Summary

Antimicrobial Compounds Produced by the Marine Actinomycete Streptomyces sp. G668

From the ethyl acetate extract of the Streptomyces sp. G668 strain, seven compounds were isolated: 9H-pyrido[3,4-b]indole (1), L-tryptophan (2), indole-3-carboxylic acid (3), 3-indolylacetic acid (4), cyclo-(Pro-Ala) (5), uracil (6), thymine (7). Their structures were elucidated by nuclear magnetic resonance spectroscopy (NMR), mass spectroscopy (MS) and comparison with the reference data. Compound 1 exhibited moderate antibacterial activity against Escherichia coli ATCC25922 and compound 5 strongly inhibited Candida albicans ATCC10231.
