Two new mohangic acid derivatives from the deep-sea bacteria Alcanivorax dieselolei BC-5

Abstract

Mohangic acids are a class of p-aminoacetophenonic acids that contain a conjugated triene or diene moiety. Herein, this paper reports two new mohangic acids E and F (1-2) together with a known compound mohangic acid A (3), which were isolated from the deep-sea sediment-derived bacteria Alcanivorax dieselolei BC-5. The structures of 1 and 2 were established by HRESIMS, 1 D and 2 D NMR, and IR spectroscopy.
