Therapeutic Applications of Natural Products in Biomedicine and Pharmacotherapy

Natural products are the fundamentals of drug discovery due to their exceptional structural diversity and biological activity's evolutionary optimization. The review provides a critical and integrative analysis of natural products in pharmaceutical chemistry, highlighting their significance for current biomedicine and pharmacotherapy. The review is organized around a system that connects structure, function, and translation, focusing on structural analysis, scaffold design, and mechanistic understanding in major disease-relevant therapeutic areas. Investigations on representative compounds like paclitaxel, artemisinin, and curcumin are presented to explain the way molecular architecture regulates pharmacological activity, drug selectivity, and clinical performance. The review evaluates significant medicinal chemistry strategies, including semisynthetic modification, prodrug design, and scaffold optimization, and their crucial roles in enhancing potency, pharmacokinetics, and safety. We critically examine the latest advancements in drug delivery technologies, particularly those based on nanotechnology and carrier-free methods, regarding their translational potential and regulatory concern. Current challenges pertaining to pharmacokinetics and ADMET properties, as well as the standardization of analysis, are also examined, emphasizing their impact on reproducibility in research. Researchers investigate the role and limitations of emerging fields such as genome mining, synthetic biology, and network pharmacology in enhancing discovery pipelines. Thus, this review integrates chemical, pharmacological, and translational approaches and suggests an effective strategy to overcome challenges in the development of natural products as the next generation of precision medicine therapeutic agents.
