Special Issue Information

Dear Colleagues,

Cancer, chronic inflammation, and microbial resistance remain among the most pressing global health challenges. The limitations of conventional therapies have prompted research groups worldwide to explore novel therapeutic strategies to address these issues. In this context, natural products offer an attractive alternative due to their structural diversity, multi-targeted actions, and favorable safety profiles. Moreover, emerging trends in natural product research—artificial intelligence, virtual screening, and molecular docking—are revolutionizing the paradigm for discovering new active compounds. These tools, combined with omics approaches and the exploration of understudied ecosystems, are facilitating the development and design of more precise and sustainable drugs with greater potential to overcome current challenges.

This Special Issue welcomes original research articles focused on the analysis of the anticancer, anti-inflammatory, and antimicrobial properties of natural extracts, isolated compounds, or formulated products, and their mechanisms of action. Studies involving in vitro and in vivo evaluations, or clinical trials, are encouraged. By bringing together interdisciplinary perspectives, this collection seeks to drive innovation and deepen the understanding of natural products in the development of therapies for cancer, inflammation, and infectious diseases.

Background/Objectives: Annona muricata (AM), commonly known as soursop or guanabana, has long been used in traditional medicine for its purported anticancer properties. However, scientific studies evaluating its potential enhancing or additive effects with conventional antineoplastic drugs (ADs) remain limited. This study aimed to assess the cytotoxic effects of an aqueous AM infusion alone and in combination with standard ADs in cancer cell lines, while also evaluating its safety in healthy cells. Additionally, we explored the potential molecular interactions of AM metabolites with therapeutic targets using silico modeling. Methods: An AM infusion (125 and 250 µg/mL) was tested on two cancer cell lines—MDA-MB-231 (human triple-negative breast cancer) and TC-1 (murine HPV16-positive cancer)—as well as healthy human leukocytes and a non-tumorigenic mouse lung cell line. Cell viability was assessed using the Alamar Blue™ assay. The combined effects of AM with multiple first-line ADs were evaluated. In silico molecular docking was performed with Molegro Virtual Docker to assess the interaction of AM metabolites (quercetin and hyperoside) with the A2B adenosine receptor. Additionally, the physicochemical properties of 13 AD were analyzed to explore correlations with cytotoxic outcomes. Results: AM infusion alone exhibited low cytotoxicity in both cancer and healthy cell types. However, when combined with ADs, it enhanced cytotoxic effects in cancer cells while sparing healthy cells at the evaluated concentrations. Docking studies revealed strong interactions between quercetin and hyperoside (major metabolites in the AM infusion) and the A2B receptor, supporting a possible mechanistic explanation for the observed effects. Conclusions: AM infusion may act as a chemical modulator, potentiating the effects of conventional ADs in cancer cells while preserving normal cell viability. These findings encourage further preclinical exploration of AM as a complementary agent in integrative oncology. Full article
