Abstract
Microbially-derived secondary me tabolites have long been regarded as a crucial resource for drug development due to their structural diversity and biological activities. This study aims to systematically evaluate the potential of microbial secondary me tabolites in the discovery of novel drugs and explore their application values in anti-infection, anti-cancer, and immune regulation fields. By integrating genomic mining techniques with high-throughput screening methods, we conducted a comprehensive analysis of microbial strains from diverse ecosystems, successfully identifying several compounds with significant pharmacological activities. The findings suggest that some underexplored microbial groups may harbor rich chemical diversity, with certain compounds exhibiting superior activity profiles compared to existing drugs. Furthermore, this study proposes a novel target association model based on me tabolic network prediction, offering new insights into the rapid identification of potential drug mechanisms of action. The results indicate that combining modern bioinformatics tools with traditional isolation and purification techniques can substantially enhance the efficiency of secondary me tabolite development. In conclusion, microbially-derived secondary me tabolites still hold immense potential for drug development, and the application of interdisciplinary approaches will further advance progress in this field.
