✦ Synopsis

Two new phenylpentadienamides isolated from the culture filtrate of Streptomyces sp. were assigned the structures 5-(4-aminophenyl)penta-2,4-dienamide (2) and N2-[5-(4-aminophenyl)penta-2,4-dienoyl]-~-~utamine (3). In addition, 5-(4-aminophenyl)penta-2,4-dienoic acid (1) has been isolated, and its spectroscopic characteristics are reported for the first time. Compounds 1-3 exist in both the (2E,4E)-and (2E,4Z)-configurations. Electrospray and tandem MS, and HPLC/MS proved to be particularly suitable for the characterization of these metabolites.
