Antimicrobial/Antibacterial Natural Product

Antimicrobial/Antibacterial Natural Products refer to active chemical substances or natural products derived from nature (such as plants, fungi, and microbial metabolites) that inhibit or kill bacteria and other microorganisms. Throughout human history, various cultures have long utilized natural antimicrobial plants and fermented products for infection prevention and treatment. Compared to synthetic antibiotics, natural antibiotics often exhibit greater structural diversity and unique molecular frameworks. They hold potential advantages in biocompatibility, cellular uptake capacity, and target-binding specificity, providing crucial molecular sources for the development of novel antimicrobial drugs.
