Special Issue Information

Dear Colleagues,

Since ancient times, plant-derived products have been used as traditional medicines, becoming an essential source of drugs. The significant potential of plants, the majority of which remains unexplored, for providing new active chemical entities encourages scientists to continue researching them. These structures could become promising scaffolds to inspire the design and development of novel therapeutic leads able to enrich libraries to be used in drug discovery pipelines.

This Special Issue intends to collect cutting-edge research and review works illustrating the potential of plant products to reflect upon the approaches of such drug discoveries and bring together organic chemists, pharmacognocists, pharmacologists, toxicologists, biologists, artificial intelligence experts, computer-aided drug design scientists, and clinicians working as a multidisciplinary team in the area of natural products.

We do hope that this Special Issue will provide extensive and applied knowledge of interest to scientists, such that they contribute to finding new avenues to develop potential therapeutic agents of natural origin against diseases.

Potential topics include but are not limited to the following:

  • Characterization of compounds obtained from plants with activity against pathogenic microorganisms, enzymes, or cancer;
  • In vitro screening of an important number of plant extracts with activity against pathogenic microorganisms, enzymes, or cancer;
  • In vivo models for testing plant-derived products with activity against pathogenic microorganisms, enzymes, or cancer;
  • Mechanisms of action of plant-derived compounds active against pathogenic microorganisms, enzymes, or cancer;
  • Computer-aided drug design (CADD) as a virtual tool for the screening and prediction of bioactive compounds;
  • Evaluation of synergy among bioactive chemical compounds (plant-derived and synthetic);
  • Synthetic derivatives of bioactive plant-derived compounds accompanied by their biological evaluation data and corresponding structure–activity relationship studies (SARSs).

Fuchsia standishii J.Harrison is a species widely used in traditional medicine in southern Ecuador for treating various ailments, including high blood pressure, as an antacid and a relaxant. The pharmacological basis for these traditional uses is unknown. Given the reported anti-inflammatory and cytotoxic properties of the Onagraceae family, we investigated the plant’s potential for addressing chronic conditions. This study explored the bioactive potential of polar extracts from the aerial parts of F. standishii, focusing on antiproliferative activity against a panel of human tumor cell lines (A549, HBL-100, HeLa, SW1573, T-47D). The plant material was sequentially extracted and partitioned into nine fractions. All fractions were screened for antiproliferative activity, and the most active fractions were further evaluated for their mechanism of cell death (apoptosis/necrosis), genotoxicity, and induction of oxidative stress. Specialized metabolites in the fractions were characterized using UHPLC-DAD-MS3 analysis. F. standishii extracts showed potent antiproliferative activity. The dichloromethane fraction (MWD) was the most active (GI50 range: 8.5–39 µg/mL), demonstrating the ability to induce apoptosis in tumor cells and cause genotoxic damage linked to oxidative stress. The UHPLC-DAD-MS3 analysis successfully characterized the specialized metabolites present in the active fractions. The initial aqueous extract yielded a total of 47 secondary metabolites, 15 of which remained unassigned. F. standishii possesses a promising pharmacological profile that extends beyond its documented traditional uses. The MWD fraction represents a plausible source of novel anti-cancer agents due to its ability to induce apoptosis, supporting further bioguided investigation of this ethnobotanically relevant species.
