Special Issue Information

Dear Colleagues,

Natural compounds continue to serve as essential resources and sources of inspiration in drug discovery, offering a wide range of chemical diversity and biological potential. Extracts and isolated compounds from medicinal plants and marine organisms have long been investigated for their therapeutic value across various disease models. These natural products typically comprise complex mixtures containing volatile, semi-volatile, and polar molecules capable of interacting with key cellular targets.

Of particular interest are extracts and secondary metabolites, which exhibit a broad spectrum of pharmacological properties. These include antioxidant activity through free radical scavenging and regulation of redox-sensitive signaling pathways; anti-inflammatory effects via suppression of pro-inflammatory cytokines and inhibition of transcription factors such as NF-κB; anti-tumor and anti-cancer actions involving induction of apoptosis, inhibition of angiogenesis, and cell cycle arrest; and cardioprotective effects by modulating lipid metabolism, vascular integrity, and oxidative stress responses. These multifaceted bioactivities highlight the importance of investigating both the chemical composition and the underlying molecular mechanisms of action using advanced biological and analytical methods.

This Special Issue aims to gather scientific papers focusing on the chemical characterization, bioactivity profiling, and mechanistic exploration of natural extracts and compounds from herbal medicine. We welcome submissions that apply molecular and cellular biology approaches to elucidate the pharmacological properties of natural products from herbal medicine. Studies integrating phytochemistry, pharmacology, and biotechnological innovation are particularly encouraged.

Importantly, the exact active ingredient of the natural origin extract must be reported in the submitted research manuscript, as papers describing the effects of mixed extractions from natural origins do not fall within the scope of this journal.

Dr. Pham Giang Nam (nam.phamgiang@phenikaa-uni.edu.vn) is the Guest Editor Assistant, and Dr. Ángeles Carlos-Reyes helps manage this Special Issue.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Avicennia marina, commonly known as the grey mangrove, is a salt-tolerant species widely distributed in coastal and estuarine ecosystems. Traditionally, it has been used in folk medicine to treat skin diseases, rheumatism, and ulcers due to its anti-inflammatory and antimicrobial properties. However, comprehensive studies on the chemical constituents and their pharmacological effects remain limited. The dried powder of the aerial parts of A. marina (3.6 kg) was successfully extracted three times with methanol (20 L × 3, each for 2 h) using a multifunctional ultrasonic cleaner operated at 25 °C with a 50% amplitude setting. In this study, the methanolic extract of the aerial parts of A. marina led to the isolation of eight compounds, including two previously unreported iridoid glycosides—avicenosides A and B (1 and 2)—and six known compounds: techtochrysin (3), 7,4′-di-O-methyl-apigenin (4), luteolin (5), kaempferol (6), trans-caffeic acid (7), and 3,4-dihydroxybenzoic acid (8). Their chemical structures were elucidated using nuclear magnetic resonance (NMR) spectroscopy and high-resolution electrospray ionization mass spectrometry (HR-ESI-MS) and compared with previously published data. Moreover, the absolute configuration of the sugar moieties in the new compounds was also identified. All isolated compounds were evaluated for their cytotoxicity against HepG2 and A549 cancer cell lines. The results indicate potential cytotoxicity of the secondary metabolites from A. marina and provide evidence of their promising role as lead compounds for the development of novel anticancer agents.
