摘要
The actinomycete strain FIM06-0036 was isolated from marine sponge sample collected from the East China Sea and identified as Verrucosispora sp. based upon the results of 16S rRNA sequence analysis. One new alkaloid, 2-ethylhexyl 1H-imidazole-4-carboxylate (1), together with a known alkaloid butyl 1H-imidazole-4-carboxylate (2) was obtained from the fermentation products of this strain, the structures of compounds 1 and 2 were determined by their detailed analysis of 1 D, 2 D NMR and HR-ESI-MS data, along with literature data analysis. Compounds 1 and 2 were evaluated for their antimicrobial activity with MIC (minimum inhibitory concentration) values ranging from 8 to 256 mu g center dot mL(-1) against Helicobacter pylori, Klebsiella Pneumonia, Staphylococcus aureus and Enterococcus faecalis.
