Abstract

Many useful natural products are usually screened based on their biological activities. On the other hand, various natural products can be detected based on their physicochemical properties. We have already reported the isolation and characterization of mangromicins from a cultural broth of Lechevalieria aerocolonigenes K10-0216 using physicochemical screening. In this report, we have conducted the mass spectrometry-based screening of new mangromicin analogs based on the neutral loss pattern originated from the unique cyclopentadecane skeleton of mangromicins. Two novel analogs were detected showing characteristic neutral loss pattern found in eight known mangromicin analogs. We propose the structures of the newly-found analogs based on the mass spectrometric as well as genomic and metabolic pathway data.
