Novel cytocidal compounds designated oxopropalines A, B, D, E and G were isolated from the fermentation of an actinomycete namedStreptomyces sp. G324, a strain that also produced an antitumor antibiotic, lavendamycin. All these compounds possessed a β-carboline chromophore. The structures of the oxopropalines were elucidated by several NMRspectral analyses and other spectroscopic experiments.
