Genome-driven discovery of new serrawettin W2 analogues from Serratia fonticola DSM 4576

Org Biomol Chem. 2023 Nov 22;21(45):9029-9036. doi: 10.1039/d3ob01642k.

Abstract

By expressing a multimodular NRPS gene sefA from Serratia fonticola DSM 4576 in E. coli, four new serrawettin W2 analogues, namely sefopeptides A-D (1-4), were isolated and structurally characterized and their biosynthesis was proposed. A bioactivity assay showed that sefopeptide C (3) exhibits moderate cytotoxic activity against acute promyelocytic leukemia NB4 cells.
