Abstract

:
Cyclodipeptides, called 2,5-diketopiperazines (2,5-DKPs), are obtained by the condensation of two amino acids. Fungi have been considered to be a rich source of novel and bioactive cyclodipeptides. This review highlights the occurrence, structures and biological activities of the fungal cyclodipeptides with the literature covered up to July 2017. A total of 635 fungal cyclodipeptides belonging to the groups of tryptophan-proline, tryptophan-tryptophan, tryptophan–Xaa, proline–Xaa, non-tryptophan–non-proline, and thio-analogs have been discussed and reviewed. They were mainly isolated from the genera of Aspergillus and Penicillium. More and more cyclodipeptides have been isolated from marine-derived and plant endophytic fungi. Some of them were screened to have cytotoxic, phytotoxic, antimicrobial, insecticidal, vasodilator, radical scavenging, antioxidant, brine shrimp lethal, antiviral, nematicidal, antituberculosis, and enzyme-inhibitory activities to show their potential applications in agriculture, medicinal, and food industry.

1. Introduction

Cyclodipeptides (or cyclic dipeptides) are usually called 2,5-diketopiperazines (2,5-DKPs) or dioxopiperazines, and result from the condensation of two amino acids such as tryptophan, proline, alanine, histidine, leucine, isoleucine, phenylalanine, serine, and tyrosine [1]. They are the smallest cyclopeptides, and are distributed in many organisms including fungi, bacteria, plants and animals [1,2,3]. Since the first report in 1924, a large number of bioactive cyclodipeptides has been discovered to show cytotoxic, antitumor, antiviral, antifungal, antibacterial, antiprion, antioxidant, antihyperglycemic as well as biofilm and glycosidase inhibitory activities [2,3,4]. Some cyclodipeptides (e.g., tryprostatin A (103), tryprostatin B (104), FR106969 (590), and phenylahistin (392)) showed their potential applications [1].
Among the organisms, fungi have been considered as the most important sources of novel and bioactive cyclodipeptides. More and more cyclodipeptides with interesting biological activities have been isolated and characterized from fungi. However, no detailed and comprehensive summary of the fungal cyclodipeptides on their occurrence, structures and biological activities has been reported though chemistry and biology of the cyclodipeptides from either all organisms or a certain class of cyclodipeptides have been documented [3,5,6]. In this review, we aim to describe the diversity of chemical structures and biological activities of the fungal cyclodipeptides and their analogs. A total of 635 fungal cyclodipeptides have been discussed and reviewed with literature covered up to July 2017. According to their biosynthetic origins and structural characters, these cyclodipeptides are classified as tryptophan–proline, tryptophan–tryptophan, tryptophan–Xaa (Xaa is indicated as an unspecified amino acid), proline–Xaa, non-tryptophan–non-proline, and thio analogs. Some special cyclodipeptides (e.g., gunnilactams A–C (378–380)), which did not belong to 2,5-DKPs, were also included in the group of non-tryptophan-non-proline analogs.

2. Tryptophan–Proline Cyclodipeptides

Tryptophan and proline are simultaneously incorporated into the cyclodipeptides in fungi. The proline residue adopts a cis-conformation about the Xaa–Pro tertiary amide bond and hence makes the Xaa–Pro sequence prone to cyclodipeptide formation. The tryptophan-proline cyclo(l-Trp–l-Pro) core was derived from condensation of tryptophan and proline residues, and this was often further modified by heterocyclization and isoprenyl addition [6]. The occurrence and biological activities of the tryptophan-proline cyclodipeptides from fungi are listed in Table 1, and their structures are provided in Figure 1.
About 116 tryptophan-proline cyclodipeptides have been isolated from fungi so far. They are mainly distributed in the genera Aspergillus and Penicillium, and are also distributed in other genera such as Alternaria, Paecilomyces, and Pseudallescheria.
(+)-Austamide (4) and (+)-deoxyisoaustamide (28) were isolated from the maize meal cultures of the toxigenic fungus Aspergillus ustus, and (+)-austamide (4) caused acute toxicosis in day-old ducklings [7].
Fumitremorgin C (40) and its derivatives (38, 39) were identified in Aspergillus fumigatus from the holothurian Stichopus alternata. They displayed significant cytotoxic activity against MOLT-4 (human acute lymphoblastic leukemia cells), A-549 (human lung adenocarcinoma epithelial cells), and HL-60 (human promyelocytic leukemia cells), which speculated that this cytotoxic activity may be linked to hydroxyl groups in the side chains of the molecules [8]. Demethoxyfumitremorgin C (26) from marine-derived Aspergillus fumigatus showed inhibitory activity in the mouse cell cycle against tsFT210, and also inhibited tumor cell cycle arrest at G2/M with a minimum inhibitory concentration (MIC) value of 0.45 μM [9].
18-Oxotryprostatin A (77) was isolated from the marine-derived fungus Aspergillus sydowi and found to exhibit weak cytotoxic activity against A-549 cells with a median inhibitory concentration (IC50) value of 1.28 μM [10]. This compound was also obtained from the endophytic fungus Aspergillus fumigatus from Melia azedarach to display plant growth inhibitory activity [11].
Spirotryprostatins (87–94) were isolated from Aspergillus fumigatus. These compounds showed cytotoxic activity by inhibiting mammalian cell cycle at G2/M phase [8,12,13].
Stephacidin B (98) was isolated from Aspergillus ochraceus. This compound exhibited potent cytotoxic activity against LNCaP (a testosterone-dependent prostate cancer cell line), with IC50 values from 91 to 621 nM [14].
Both tryprostatins A (103) and B (104), which are prenylated, were isolated from the fermentation broth of the marine-derived fungus Aspergillus fumigatus [15]. Tryprostatin A (103) was an inhibitor of the multidrug-resistance breast cancer protein (BCRP) that mediated resistance to chemotherapeutics in breast cancer treatment [16], whereas tryprostatin B (104) was a mammalian cell-cycle inhibitor, attractive as a potential anticancer agent [17]. Furthermore, tryprostatin A (103) exhibited inhibitory activity on the elongation of lettuce shoots [11].

3. Tryptophan–Tryptophan Cyclodipeptides

The ditryptophan cyclodipeptides, which have two tryptophan units, are widely distributed in filamentous fungi, especially in the genera Penicillium and Aspergillus. Their occurrence and biological activities are listed in Table 2, and the structures are provided in Figure 2.
Amauromine (117) from Amauroascus sp. [54] was identical with nigrifortine (117) from Penicillium nigricans. It is a diannulated DKP analog which shows hypotensive vasodilating activity [55]. This compound was later isolated from Auxarthron reticulatum, and identified as a selective cannabinoid CB1 receptor antagonist [56].
Epiamauromine (120) and N-methylepiamauromine (127) were isolated from the sclerotia of Aspergillus ochraceus. They caused moderate reduction in weight gain against the corn earworm Helicoverpa zea [57].
Fellutanines A–D (121, 123–125), the analogs of cyclo(l-Trp–d-Trp), were isolated from the cultures of Penicillium fellutanum. Among them, only fellutanine D (125) was diannulated and displayed cytotoxic activity against K-562 (human myeloid leukemia cells), L-929 (mouse fibroblastic cell), and HeLa (human epitheloid cervix carcinoma cells) with IC50 values of 9.5, 11.6 and 19.7 μg/mL, respectively [58].
Novoamauromine (128) was obtained from Aspergillus novofumitatus CBS117520. This compound had inhibitory activity on the cell proliferation of A549, HeLa, LNCap (human prostate carcinoma cells) [59].
Okaramines A–U (129–149) have been isolated from Aspergillus aculeatus [60], Aspergillus taichungensis [61], and Penicillium simplicissimum [62,63,64,65]. Structure–activity studies indicated the importance of the azetidine and azocine rings to okaramine insecticidal activity [66]. The action of okaramine B (130) on silkworm larval neurons using patch-clamp electrophysiology revealed that this compound activated the l-glutamate-gated chloride channel (GluCl) [67].

4. Tryptophan–Xaa Cyclodipeptides

Apart from Trp–Pro and Trp–Trp cyclodipeptides, other tryptophan cyclodipeptides are also abundant in fungi and represent a structurally diverse group of natural products. Their occurrence and biological activities are shown in Table 3, and their structures are provided in Figure 3.
Aspertryptanthrins A–C (156–158) were obtained from a terrestrial-derived fungus Aspergillus sp. These compounds all contain an anthranilate unit and a tryptophan residue. In addition, aspertryptanthrin C (158) contains a rare 16-membered ring [74].
The cyclodipeptides brevicompanine C (163), cyclo(l-Trp–d-Ile) (182) and cyclo(l-Trp–d-Leu) (183) from Penicillium brevi-compactum [75], as well as cyclo(l-Trp–l-Phe) (187) from Penicillium sp. [76] accelerated the root growth of the lettuce seedlings in proportion to their concentrations from 1 to 100 mg/L.
Brevicompanines D–H (164–168) were isolated from a deep ocean sediment derived fungus Penicillium sp. [77]. Both brevicompanines E (165) and H (168) inhibited lipopolysaccharide (LPS)-induced nitric oxide production in BV2 microglial cells. Further studies showed that brevicompanine E (165) reduced lipopolysaccharide-induced production of pro-inflammatory cytokines and enzymes in microglia by inhibiting activation of activator protein-1 and nuclear factor κB and, hence, may be potentially useful for modulating neuroinflammation [78].
Cycloechinulin (190) was isolated from the sclerotia of Aspergillus ochraceus, and it showed moderate insecticidal activity against the lepidopteran crop pest Helicoverpa zea [57].
Echinulin (206) is one of the simplest classes of isoprenylated tryptophan cyclodipeptides. It was toxic to rabbits, producing a significant degree of damage to lung and liver [79].
Fructigenines A (211) and B (212) are annulated derivatives of cyclo(l-Trp–l-Phe) (187), and were isolated from Penicillium fructigenum. Only fructigenine A (211) inhibited growth of Avena coleoptiles and L-5178Y (mouse lymphoma cells), and was subsequently found to have more potent anti-inflammatory activity than indomethacin in the mouse ear edema model [80]. Fructigenine A (211) was also named rugulosuvine B (211) in Penicillium rugulosum, and showed potent anti-inflammatory and antitumor activities in vitro [81].
Neoechinulin A (234) had scavenging, neurotrophic factor-like and antiapoptotic activities. The protective properties of neoechinulin A (234) against SIN-1-induced neuronal cell death suggested that neoechinulin A (234) could protect against neuronal cell death in neurodegenerative diseases [82].
The valine analog polanrazine A (250) was isolated from the blackleg fungus Phoma lingam (teleomorph: Leptosphaeria maculans). This compound was toxic to canola (Brassica napus and B. rapa) [83].
Rubrumlines A–O (267–281) were isolated from the marine-derived fungus Eurototium rubrum. Among them, rubrumlines D (270), F (272), G (273), J (276), M (279), N (280), and O (281) showed inhibitory activity against influenza A/WSN/33 virus. Further analysis of the structure–activity relationship revealed that the analogs with an isoprenyl unit in indole ring displayed stronger cytotoxic effects than those linked by an oxygenated isoprenyl unit. Neoechinulin B (235) was also isolated from Eurototium rubrum. This compound was efficient in inhibiting influenza A/WSN/33 virus propagation even after the fifth passage. In addition, it exerted potent inhibition against H1N1 virus infected in MDCK cells, and was able to inhibit a panel of influenza virus strains including amantadine- and oseltamivir-resistant clinical isolates. The high potency and broad-spectrum activities against influenza viruses with less drug resistance made neoechinulin B (235) a new lead for the development of potential inhibitor of influenza viruses [84].
The prenylated pyranoindole derivatives talathermophilins A (284) and B (285) were isolated from a thermophilic fungus Talaromyces thermophilus strain YM1-3. Both talathermophilins A (284) and B (285) showed nematicidal activity toward the worms of the free-living nematode Panagrellus redivevus [85].
Variecolorins A–L (293–304) were isolated from halotolerant fungus Aspergillus variecolor [80], and variecolorins M–O (305–307) from deep ocean sediment-derived fungus Penicillium griseofulvum [86]. They all showed weak radical scavenging activity against DPPH [86,87].

5. Proline–Xaa Cyclodipeptides

Except Trp–Pro cyclodipeptides, other proline containing cyclodipeptides (Pro–Xaa) are also abundantly distributed in fungi. Their occurrence and biological activities are shown in Table 4, and their structures are provided in Figure 4.
Cyclo(l-Pro–l-Ala) (318) was isolated from Alternaria alternata [149] and the phytopathogenic fungus Colletotrichum gloesporoides [150]. This compound inhibited aflatoxin production in aflatoxigenic fungi without affecting fungal growth. Further investigation on the mode of action suggested that this cyclodipeptide inhibited aflatoxin biosynthesis by affecting glutathione S-transferase (GST) function in Aspergillus flavus to show its potency as the biocontrol agent [151].
Cyclo(l-Pro–l-Phe) (334) and cyclo(l-Pro–l-Tyr) (337), which were also called maculosin-2 (334) and maculosin-1 (337), were host-specific fungal phytotoxins produced by Alternaria alternata on spotted knapweed (Centaurea maculosa) to show their protential as the bioherbicides [149].
The dechlorinated cyclodipeptide, cyclo(13,15-dichloro-l-Pro–l-Tyr) (338), isolated from the fungus Leptoxyphium sp. is considered as an inhibitor of monocyte chemotactic protein-1 (CCL2)-induced chemotaxis and was 10- to 20-fold more active than the nonchlorinated from maculosin-1 (337). In addition, no cellular toxicity was observed when cyclo(13,15-dichloro-l-Pro–l-Tyr) (338) at 100 μM was in contact with human monocyte culture for 24 h, suggesting its potential as a lead structure for the future development of anti-inflammatory compounds [152].

6. Non-Tryptophan–Non-Proline Cyclodipeptides

Non-tryptophan–non-proline cyclodipeptides mean neither tryptophan nor proline is incorporated into this group of cyclodipeptides in the fungi. Their occurrence and biological activities are shown in Table 5, and the structures are provided in Figure 5.
3-Acetamino-6-isobutyl-2,5-dioxopiperazine (346) and 3-isopropyl-6-isobutyl-2,5-dioxopiperazine (383), belonging to the aliphatic isoleucine cyclodipeptide, were isolated from Cordyceps sinensis. Only 3-acetamino-6-isobutyl-2,5-dioxopiperazine (346) had cytotoxic activity against L-929, A375, and HeLa cells [169].
Azonazine (350) was isolated from a Hawaiian marine sediment-derived fungus Aspergillus insulicola, and exhibited anti-inflammatory activity by inhibiting NF-κB luciferase (IC50, 8.37 μM) and nitrate production (IC50, 13.7 μM) [170].
Cyclo(l-Phe–l-Phe) (357) originally isolated from Penicillium nigricans was also isolated from a marine mangrove endophytic fungus [171], and exhibited good anthelmintic activity against Hymenolepis nata and Schistosoma mansoni in mice [172].
Cyclic phenylalanyl serine cyclo(Phe–Ser) (358) was isolated from the insect pathogenic fungus Verticillium hemipterigenum. It exhibited concentration-dependent atypical intestinal absorption in the small intestine of rats, which consisted of passive transport, carrier-mediated absorptive transport by PEPT1, and carrier-mediated excretive transport. It also exhibited weak inhibition of several cancer cell lines and selected microorganisms [173,174].
The tyrosine analog cyclo(l-Tyr–l-Tyr) (360) isolated from the culture broth of Cordyceps sinensis reversibly blocked voltage-dependent L-type calcium channels [169].
Diatretol (365) from the fungus Clitocybe diatreta exhibited a weak antibacterial activity. A single-crystal X-ray analysis showed that diatretol (365) has a nearly planar boat conformation in the solid state [175].
Dimerumic acid (368) has been isolated from the fungus Monascus anka, traditionally used for fermentation of food, and shown to be an antioxidant with hepatoprotective actions against chemically induced liver injuries [176], as well as protecting against oxidative stress-induced cytotoxicity in the isolated rat hepatocytes [177].
Gliocladride (374) isolated from marine fungus Gliocladium sp. showed a cytotoxic effect with an IC50 value of 3.86 mg/mL against human A375-S2 melanoma cell line [178].
Gliocladrides A (375) and B (376) as well as deoxymycelianamide (363) were isolated from the marine fungus Gliocladium sp. to show cytotoxic activity against the three cell lines (HL-60, U937 and T47D) with IC50 values 11.6–52.8 μg/mL, while deoxymycelianamide (363) showed the strongest cytotoxic activity against U937 cell line with an IC50 value of 0.8 μg/mL [179].
Golmaenone (377) from the culture broth of the marine-derived fungus Aspergillus sp. exhibited a significant radical scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) and showed UV-A (320–390 nm) protecting activity which was more active than oxybenzone currently used as a sunscreen [103].
The marine-derived fungus Aspergillus sp. yielded mactanamide (386) containing an R-2,6-dihydroxyphenylalanine, which showed fungistatic activity to Candida albicans at nontoxic concentration [180].
Three siderophores NBRI16716A (388), NBRI16716B (389), and NBRI16716C (390) were isolated from the fungus Perisporiopsis melioloides Mer-f16716. Compounds NBRI16716A (388) and NBRI16716B (389) inhibited the growth of human prostate cancer DU-145 cells in the coculture with human prostate stromal cells (PrSCs) more strongly than that of DU-145 cells alone. Furthermore, both compounds showed antitumor effect against xenograft models of DU-145 cells and PrSCs in vivo [181].
Phenylahistin (392) from the culture broth of Aspergillus ustus NSC-F038 exhibited a strong growth inhibition on various tumor cell lines for its microtubule binding function to show its potency as the tubulin depolymerizing agent [182].

7. Thio-Cyclodipeptides

The thio-cyclodipeptides are 2,5-diketopiperazines containing thio functionality in bridged or open form, and their occurrence and activities have been reviewed in 2006 and 2014 [1,207]. According to the positions of the sulfur linkages, we divide thio cyclodipeptides into four subgroups: 1,4-bridged epipolythioxopiperazines (ETPs), derivatives with sulfur-bridge outside 2,5-DKP ring, nonbridged dimethylthio derivatives, and other sulfur-containing cyclodipeptides. About 232 thio-cyclodipeptides have been isolated from fungi.

7.1. 1,4-Bridged Epiplythiodioxopiperazine Analogs

The sulfur-bridged cyclodipeptides are a class of metabolites mainly dominated by the epipolythiodioxopiperazines (ETPs) [1]. The toxicity of ETPs is due to the presence of a sulfide bridge, which can inactivate proteins via reaction with thiol groups and by generation of reactive oxygen species by redox cycling [5]. The ETPs are known for their cytotoxic effect on cancer cell lines, and it has been shown mechanistically that ETPs were transcriptional antagonists that block the interaction of the p300/CBP coactivator with the hypoxia-inducible transcription factor HIF-1α by a zinc ejection mechanism, which resulted in rapid down regulation of hypoxia-inducible genes critical for cancer progression [208]. The occurrence and biological activities of 1,4-bridged epiplythiodioxopiperazine analogs from fungi are shown in Table 6, and their structures are provided in Figure 6.
The dimeric ETP chaetocin (420) was isolated from the fungus Chaetomium minutum, and, in addition to its antibacterial and cytostatic activity, was reported to have inhibitory activity against lysine-specific histone methyltransferases (HMTs), which are key enzymes in the epigenetic control of gene expression [209]. Chaetocins B (421) and C (422) from a Chaetomium sp. fermentation broth were potent inhibitors of Staphylococcus aureus, and exhibited potent cytotoxic activity against HeLa cells with IC50 values of 0.03 and 0.02 μg/mL, respectively [210].
Chaetocochins B (423) and C (424), which were isolated from Chaetomium cochliodes, showed cytotoxic activity to the cells of Bre-04 (breast cancer cells), Lu-04 (big cell lung cells), and N-04 (glioma cells) [211].
Three ETPs deoxyapoaranotin (432), acetylaranotin (408) and acetylapoaranotin (407) were isolated from Aspergillus sp. KMD 901 found in the marine sediment obtained from the East Sea of Korea. They had directly cytotoxic and apoptosis inducing effects toward HCT116 colon cancer cell lines [212].
Emethallicins A–F (444–449) were obtained from Emericella heterothallica. These compunds all displayed inhibitory activity on histamine release from mast cells [213,214,215].
The best known ETP was the small lipid-soluble gliotoxin (461), which exerted toxic effects on phagocytic cells and T-lymphocytes at low concentrations in vitro. This compound was the first ETP to be obtained from fungi. It has been isolated from a variety of fungi including species in the genera of Penicillium, Aspergillus, Gliocladium, Thermoascus, and Candida [2]. High levels of gliotoxin (461) were produced by Aspergillus fumigatus in vivo, and it appeared to be a virulence factor associated with invasive aspergillosis of immunocompromised patients [216]. Gliotoxin (461) was also a dual inhibitor of farnesyltransferase and geranylgeranyltransferase I with antitumor activity against breast cancer in vivo [217].
Two bridged disulfides epicoccin T (450) and rostratin A (493) were isolated from the endophytic fungus Epicoccum nigrum obtained from the leaves of Lysidice rhodostegia. However, they did not show detectable cytotoxic activities toward six tumor cell lines in the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay [188]. In contrast, the rostratins A–D (493–496), which were extracted from Exserohilum rostratum, were found to be modestly cytotoxic against human colon carcinoma HCT-116 [218]. Similarly, the unsaturated analogs epicorazines A (452), B (453), and C (454) isolated from the culture broth of the basidiomycete Stereum hirsutum HKI 0195 were highly cytotoxic against HeLa cells and also exhibited antiproliferative effects against several mouse fibroblast and cancer cell lines [219].
The antifungal macrolide MPC1001 (438) possessing an ETP ring was isolated from the fungus Cladorrhinum sp. KY4922, which was found in a soil sample collected in Indonesia. It possessed antiproliferative activity against the human prostate cancer cell line (DU145) with an IC50 of 9.3 nM, and had antibacterial activity against Gram-positive bacteria [220].
Secoemestrin D (500) was obtained from the endophytic fungus Emericella sp. AST0036 isolated from a healthy leaf tissue of Astragalus lentiginosus. This compound showd cytotoxic activity with IC50 values ranging from 0.06 to 0.24 μM on tumor cell lines [221].
Verticillin A (515) was obtained from Gliocladium roseum derived from submerged wood. It showed antinematodal activity against Panagrellus redivivus and Caenorhabditis elegans, and cytotoxic activity against HeLa cells with an IC50 value of 0.2 μg/mL [222]. Verticillins B (516) and C (517) were isolated from Verticillium sp. [223]. Verticillin D (518), which was isolated from Bionectria byssicola [222] and Gliocladium catenulatum [224], showed antibacterial activity against Staphylococcus aureus. Verticillins E (519) and F (520) from Gliocladium catenulatum showed antibacterial activity [224]. Verticillin G (521) from Bionectra byssicola showed antibacterial activity against Staphylococcus aureus including methicillin-resistant and quinolone-resistant varieties with minimum inhibitory concentrations (MICs) of 3–10 μg/mL [225].

7.2. Analogs with Sulfur-Bridge outside 2,5-DKP Ring

There are a group of sulfur-bridged cyclodipeptides where the sulfur linkage is outside the 2,5-diketoperazine ring. The occurrence and biological activities of fungal analogs with sulfur-bridges outside 2,5-DKP ring are shown in Table 7, and their structures are provided in Figure 7.
Both aspirochlorine (524) and tetrathioaspirochlorine (551) were isolated from Aspergillus flavus and were potent antifungals that inhibited azole-resistant Candida albicans [107]. Aspirochlorine (524) was a rather potent and selective inhibitor of fungal protein synthesis that did not inhibit bacterial or mammalian protein synthesis [267].
Epicoccins are diannulated 2,5-DKPs containing mono- or bis-cross ring sulfide/disulfide bridges. Epicoccins A–F (528–533) have been isolated from the solid-substrate fermentation culture of the Cordyceps-colonizing fungus Epicoccum nigrum [194,268]. Epicoccin A (528) showed modest antimicrobial activity against Bacillus subtilis [268].
The dimeric 2,5-DKPs vertihemiptellides A (553) and B (554) were isolated from the insect pathogenic fungus Verticillium hemipterigenum, and exhibited growth inhibitory activity against Mycobacterium tuberculosis H37Ra, and also showed moderate cytotoxic activity [174].

7.3. Nonbridged Methylthio-Containing Cyclodipeptide Analogs

Nonbridged methylthio-containing analogs were often isolated from fungi as co-metabolites with their sulfur-bridge 2,5-DKP parents. They had a related biosynthetic pathway [275]. The occurrence and biological activities of this group of fungal metabolites are shown in Table 8, and their corresponding structures are provided in Figure 8.
Alternarosin A (555) from Alternaria raphanin, a halotolerant marine fungus obtained from the sediment of the Hongdao sea salt field, showed very weak antimicrobial activity against Escherichia coli, Bacillus subtilis, and Candida albicans with MIC values ranging from 200 to 400 μM [276].
Three 2,5-DKPs, bilains A–C (558–560) and cis-bis(methylthio)silvatin (480) were isolated from the marine-derived fungus Penicillium bilaii collected in Tasmania. However, only cis-bis(methylthio)silvatin (569) showed weak cytotoxicity against NS-1 cells [161]. Both cis-bis(methylthio)silvatin (569) and its enantiomer Sch 54794 (524) were previously isolated from the fungus Fusarium chlamydosporum OUPS-N124 obtained from the marine alga Carpopeltis affinis. They exhibited weak cytotoxic activity against P388 lymphocytic leukemia cells [277].
Bis-N-norgliovictin (570) was first isolated from Gliocladium virens [233]. It was also isolated from three marine-derived fungi Aspergillus fumigatus [278], Neosartorya pseudosidcheri [136], and Dichotomomyces sp. L-8 [113]. Bis-N-norgliovictin (570) significantly inhibited lipopolysaccharide (LPS)-induced inflammation in macrophages and improved survival in sepsis, and it should be a therapeutic candidate for the treatment of sepsis and other inflammatory diseases [279].
Dehydroxybisdethiobis(methylthio)gliotoxin (577) has been isolated from the broth of a marine-derived fungus Pseudallescheria sp. and exhibited weak antibacterial activity against methicillin-resistant and multidrug-resistant Staphylococcus aureus with MIC values of 31.2 μg/mL [280].
Ent-epicoccin G (582) from the endophytic fungus Epicoccum nigrum showed potent in vitro activity (IC50, 3.07 μM) against the release of β-glucuronidase in rat polymorphonuclear leukocytes induced by platelet-activating factor [188].
The bis(methylthio)-2,5-DKP FR106969 (590) isolated from Penicillium citrinum showed high inhibitory activity against the platelet activating factor (PAF)-induced rabbit platelet aggregation to have its potency as the anti-inflammatory inhibitor [281].
The indole derivatives gliocladins A (594) and B (595) as well as glioperazine (597) have been obtained from a marine-derived fungus Gliocladium roseum PS-N132 isolated from the sea hare Aplysia qkurodai. All three 2,5-DKPs exhibited cytotoxicity against murine P388 lymphocytic leukemia cells [125].
Both haematocin (600) and mycoediketopiperazine (607) were dimethylthio 2,5-DKPs. Haematocin (600) was isolated from the phytopathogenic fungus Nectria haematococca and had inhibitory activity on the spore germination and germ-tube elongation of Magnarporte oryzae [282]. Mycoediketopiperazine (607) from the fungus Papularia sp. exhibited potent cytotoxic activity on KB cells with an IC50 value of 120 μg/mL [283].
Plectosphaeroic acids A (620) and B (621) were obtained from marine-derived fungus Plectosphaerella cucumerina. They were inhibitors of indoeamine 2,3-dioxygenase (IDO), which existed in primary tumor cells. IDO has been considered as an important molecular target for cancer therapy [254].

7.4. Other Sulfur-Containing Cyclodipeptide Analogs

Other sulfur-containing cyclodipeptide analogs included MPC1001G (633), silvathione (634) and taichunamide D (635) with their structures shown in Figure 9. MPC1001G (633) was isolated from Cladorrhinum sp. KY4922 [236], silvathione (634) from Aspergillus silvaticus [235], and taichunamide D (635) from Aspergillus taichungensis IBT 19404 [53]. Their biological activities have not been reported.

8. Conclusions and Future Perspectives

A large number of cyclodipeptides have been identified in fungi, and many have received attention not only as challenging synthetic targets but also because some of these compounds displayed diverse and interesting biological activities. Since then, interest has increased in the biosynthesis, genetics, total synthesis, biological activities, and medicinal properties of this class of natural products. Some cyclodipeptides such as tryprostatins A (103) and B (104), cyclo(l-Pro–l-Ala) (318), cyclo(l-Pro–l-Phe) (334), cyclo(l-Pro–l-Tyr) (337), phenylahistin (392), and FR106969 (590) have displayed their potential applications in agriculture and medicinal industry [16,17,149,151,182,281].
The fungal cyclodipeptides are mainly distributed in the genera of Aspergillus and Penicillium. However, the cyclodipeptides in the remaining genera seem to be less explored. Further identification and exploration of the cyclodipeptides from all of the fungal genera are needed. In recent years, more and more cyclodipeptides have been isolated from marine-derived and plant endophytic fungi [297,298,299,300]. These fungi inhabiting particular environments could be rich sources of biologically active cyclodipeptides that are indispensable for medicinal and agricultural applications.
The biological activities (shown in Table 1, Table 2, Table 3, Table 4, Table 5, Table 6, Table 7 and Table 8) of the cyclodipeptides reported by each investigator were random and limited. Systematical screening of biological activities for each cyclodipeptide should be necessary. In most cases, the biological activities as well as the mode of action of fungal cyclodipeptides have been investigated based on in vitro studies or animal modes. Few studies have been performed at the level of clinical trials in patients. Effective research and development methods for these compounds should be explored to maximize their usefulness in the drug discovery and development processes [6]. For the diverse biological activities, the cyclodipeptides from fungi are expected to inspire medicinal chemists in their search for better agents such as antitumors, antifungals, and antibacterials than existing ones [297].
It is very important to understand biosynthetic mechanisms of the cyclodipeptides in fungi. These need to combine their biochemical and genetic approaches. More and more designed biologically active cyclodipeptides will be expected to be produced by genetic manipulation. With a good understanding of the biosynthetic pathways of bioactive cyclodipeptides, we can not only increase outputs of the beneficial cyclodipeptides but also block biosynthesis of some harmful cyclodipeptides by specific interferences [6].
