1-Methoxypyrrole-2-carboxamide—A new pyrrole compound isolated from Streptomyces griseocarneus SWW368

A new pyrrole compound, 1-methoxypyrrole-2-carboxamide, was obtained from a culture broth of Streptomyces griseocarneus SWW368, which was isolated from the rhizospheric soil under a Para rubber tree (Hevea brasiliensis). The chemical structure was elucidated by 1D NMR, 2D NMR, and MS, as a pyrrole ring with a N-methoxy group and a primary amide group. It exhibited antibacterial properties against Kocuria rhizophila, Staphylococcus aureus and Xanthomonas campestris pv. oryzae; however, cytotoxicity of the compound at 714 μM against several mammalian tumor cell lines, i.e. A549, PANC1, HT29, HT1299 and HeLa S3, were not detected.
