Drug Discovery from Diverse Bacteria – Bioactivity-guided Isolation of Known and New Metabolites

Creator:: Zhu, Chenxi
Abstract:: Exploring bioactive natural products has contributed largely to clinically approved drugs we have been using over the last 100 years. Especially among the anti-infective drugs, around 70% of currently used antibiotics were discovered or derived from microbial secondary metabolites, among them compounds like vancomycin, chloramphenicol, and erythromycin. Facing the unavoidable...
