Tauramamide, a lipopeptide antibiotic produced in culture by Brevibacillus laterosporus isolated from a marine habitat: structure elucidation and synthesis.
Tauramamide (1), a new lipopeptide antibiotic, is produced by cultures of the marine bacterial isolate Brevibacillus laterosporus PNG276 obtained from Papua New Guinea. Tauramamide was isolated as its methyl and ethyl esters 2 and 3, whose structures were elucidated by analysis of NMR, MS, and chemical degradation data. A total synthesis of tauramamide (1) and tauramamide ethyl ester (3) confirmed the structure proposed from spectroscopic analysis and provided the natural product for antimicrobial testing. Tauramamide (1) and ethyl ester 3 show potent and relatively selective inhibition of pathogenic Enterococcus sp.
