Special Issue Information

Dear Colleagues,

Recently, we accepted an invitation to serve as Guest Editors for this Special Issue, " Natural Products and Derivatives in Human Disorders” of the journal Molecules (ISSN 1420-3049 https://www.mdpi.com/journal/molecules) with an impact factor 3.098 (2017) in Biochemistry and Molecular Biology and Chemistry, multidisciplinary areas. In this regard, we would be pleased if you would agree to contribute an original research paper, a short communication, or a focus review to this issue. Provided below is some information that you may find useful in your consideration of this invitation.

This Special Issue aims to collect and disseminate some of the most significant and recent contributions in the use of natural compounds and derivatives to reduce the risk of developing inflammatory and oxidant diseases such as cancer and others human disorders. Articles regarding the anticancer activity of natural compounds and derivatives are particularly encouraged.

Natural products are bioactive compounds synthesized by terrestrial and marine plants, microorganisms and animals. Traditionally, they have been used in the prevention and treatment of various human diseases in different cultures. In parallel, chemical derivatives of these natural compounds have been used in order to enhance their bioactivities. During the last ten years, most of them have been reported to have a variety of interesting and significant biological properties, such as analgesic, anti-allodynic, anti-diabetic, anti-oxidant, anti-parasitic, antimicrobial, anti-viral, anti-atherogenic, anti-inflammatory, anti-proliferative, anti-tumor, growth-stimulating activities, as well as cardio and neuro-protective activities. However, special attention has been focused on the study of their anti-tumor capacity, through the potential modulation of cancer initiation and growth, cellular differentiation, apoptosis and autophagy, angiogenesis, and metastatic dissemination. Moreover, a considerable number of studies reported the relation of the anticancer effect with their anti-inflammatory and antioxidant activities. Besides these capacities, the use of natural compounds and derivatives represent one of the most promising strategies to treat metabolic disorders (oxidative stress, diabetes, obesity, metabolic syndrome, and so on). The biological activity of natural extracts without a proper chemical characterization will not be considered.

Topics:

  • New natural compounds and derivatives as anticancer agents
  • Use of natural compounds and derivatives as anti-inflammatory agents in human disorders
  • Natural products and derivatives in oxidative stress associated with human diseases
  • Molecular mechanism implicated of natural products and derivatives
  • Effects of natural products and derivatives on nutrition and diet on human diseases
  • Type of natural product and derivatives with potential bioactive, extraction and synthesis

Osteoarthritis (OA) is the common form of arthritis and is characterized by disability and cartilage degradation. Although natural product extracts have been reported to have anti-osteoarthritic effects, the potential bioactivity of Ryupunghwan (RPH), a traditional Korean medicinal botanical formula that contains Astragalus membranaceus, Turnera diffusa, Achyranthes bidentata, Angelica gigas, Eclipta prostrata, Eucommia ulmoides, and Ilex paraguariensis, is not known well. Therefore, the inhibitory effects of single compounds isolated from RPH on the OA-related molecules were investigated using IL-1β-stimulated chondrosarcoma SW1353 (SW1353) cell model. Two bioactive compounds, isomucronulatol 7-O-β-d-glucoside (IMG) and ecliptasaponin A (ES) were isolated and purified from RPH using column chromatography, and then the structures were analyzed using ESI-MS, 1H-NMR, and 13C-NMR spectrum. The expression or amount of matrix metalloproteinase 13 (MMP13), COX1/2, TNF-α, IL-1β or p65 was determined by RT-PCR, Western blot, and enzyme-linked immunosorbent assay (ELISA). RPH pretreatment reduced the expression and amounts of MMP13, and the expression of collagen II, COX1/2, TNF-α, IL-1β or p65, which were increased in IL-1β-stimulated SW1353 cells. IMG reduced the expression of all OA-related molecules, but the observed inhibitory effect was less than that of RPH extract. The other single compound ES showed the reduced expression of all OA-related molecules, and the effect was stronger than that in IMG (approximately 100 fold). Combination pretreatment of both single components remarkably reduced the expression of MMP13, compared to each single component. These synergic effects may provide potential molecular modes of action for the anti-osteoarthritic effects of RPH observed in clinical and animal studies. Full article

Dry eye disease is affected by a broad range of causes such as age, lifestyle, environment, medication and autoimmune diseases. These causes induce tear instability that activates immune cells and promotes expression of inflammatory molecules. In this study, we investigated the therapeutic effects of an ethanolic extract of Aucuba japonica (AJE) and its bioactive compound, aucubin, on dry eye disease. The human corneal cells were exposed to desiccation stress induced by exposing cells to air, so that viability was decreased. On the other hand, pre-treatment of AJE and aucubin restored cell survival rate depending on the dose under the dry condition. This result was confirmed again by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining. The mRNA expression of inflammatory molecules was reduced by the pretreatment of AJE and aucubin under the dry state. The therapeutic effects of AJE and aucubin were examined in the animal model for dry eye induced by unilateral excision of the exorbital lacrimal gland. Declined tear volumes and corneal irregularity in the dry eye group were fully recovered by the administration of AJE and aucubin. The apoptotic cells on the cornea were also decreased by AJE and aucubin. Therefore, this study suggests that administration of AJE can be a novel therapeutic for dry eye disease and that the pharmacological activities of AJE may be in part due to its bioactive compound, aucubin.
