Abstract:

Nine metabolites thymine (1), pyrrole-2-carboxylic acid (2), kalamycin (3), 3-indole propionic acid (4), indol-3-carboxylic acid (5), N-acetyl-tyramine (6), 2'-deoxythymidine (7), N-β-acetyltryptamine (8), and triethylamine hydrochloride (9) were isolated by column and preparative thin layer chromatography from the extract of fermented broth of Streptomycete sp. S007. Their structures were established by NMR and MS data. Among of them, 9 was firstly obtained from Streptomycete; The brine shrimp bioassay showed the mortality rates of kalamycin to brine shrimp are 86. 5% at a concentration of 40 µg/mL, indicating kalamycin possessed significant toxicity on brine shrimp.
