Bioactive Natural Products: Chemistry And Biology -

: Unlike many synthetic drugs, natural products often act through synergistic, multi-target mechanisms, influencing redox dynamics, membrane architecture, and signaling pathways simultaneously. 3. Modern Discovery Techniques

Natural products are categorized into major classes based on their chemical structures and biosynthetic origins:

: The largest group of natural products, built from five-carbon isoprene units. Examples include the antimalarial agent artemisinin. Bioactive Natural Products: Chemistry and Biology

The chemistry of these products is inextricably linked to their biology through specialized enzymatic pathways.

Bioactive natural products represent a diverse array of chemical scaffolds evolved over millions of years to perform specific biological functions. These compounds, primarily secondary metabolites, serve as a cornerstone for modern drug discovery, contributing to approximately 24% of all approved drugs. 1. Classification and Chemical Diversity : Unlike many synthetic drugs, natural products often

: Polyphenolic compounds like curcumin and quercetin, known for their significant antioxidant, anti-inflammatory, and cardioprotective properties.

: Assembled from acetate and malonate units via "assembly line" enzymes, producing complex structures like erythromycin. Examples include the antimalarial agent artemisinin

: Nitrogen-containing heterocyclic compounds often derived from amino acids. They frequently exhibit potent pharmacological effects, such as the analgesic properties of morphine.
