Advances in Natural Products and Their Biological Activities

The ongoing exploration of natural products remains fundamental to drug discovery, as they offer exceptional structural diversity and complex biological activities. The Special Issue, "Advances in Natural Products and Their Biological Activities," published in Molecules and Guest-Edited by Dr. Irwin Rose Alencar Menezes, Prof. Dr. Henrique Douglas Melo Coutinho, Prof. Dr. Almir Gonçalves Wanderley, and Prof. Dr. Jaime Ribeiro-Filho, serves as a comprehensive compendium of recent research in this evolving field. This collection presents studies that emphasize the potential of natural compounds, semi-synthetic derivatives from plants, essential oils, and metabolites from microorganisms. These investigations address significant human health challenges, such as cancer, infectious diseases, and inflammatory disorders. The Special Issue comprises original research articles and reviews that reflect the global effort to characterize, optimize, and elucidate the molecular mechanisms of bioactive molecules. It also illustrates how traditional knowledge can inform the discovery of novel bioactive resources. The research featured in this Special Issue employs advanced methodologies to investigate how extraction systems, seasonal variations, and innovative formulations can improve the yield and pharmacological efficacy of active compounds. Furthermore, the collection underscores the essential role of natural products in providing new chemical entities and innovative strategies for contemporary pharmacotherapy.
