Abstract

Through a combination of chemical and molecular analysis, a new polyene macrolactam named micromonolactam was obtained from two marine-derived Micromonospora species. This new polyene metabolite is a constitutional isomer of salinilactam A but contains a different polyene pattern and one cis double bond, in contrast to the all trans structure reported for salinilactam A. The molecular analysis data also established that micromonolactam is a hybrid polyketide derived from 11 polyketide units and a modified glutamate starter unit.
