Abstract

Formicins A-C (1-3) were discovered from Streptomyces sp. associated with wood ants. The structures of 1 and 2 were elucidated as indenone thioesters bearing N-acetylcysteamine based on spectroscopic analysis. The configurations of 1-3 were determined by the analysis of ROESY correlations, the phenylglycine methyl ester method, and chemical derivatization from 3 to 2. Formicin A inhibited the growth of human triple-negative breast cancer cells by regulating the liver kinase B1-mediated AMPK signaling pathway.
