Two novel secondary metabolites, bagremycin A (2) and B (3), were detected in the culture filtrate of Streptomyces sp. Tü 4128 by HPLC-diode-array screening. They are phenol esters of 3-amino-4-hydroxybenzoic acid with a derivative of p-coumaric acid and show a moderate activity against Gram-positive bacteria and some fungi.
