Genistein, a inhibitor of the progression of G$_{1}$ and G$_{2}$ phase of the mammalian cell cycle, was discovered through a unique screening system, in which effects of microbial metabolites on the cycle progression of the cultured mouse mammalian carcinoma cell were monitored by flow cytometry. The inhibitor was extracted from the fermentation broth of Streptomyces sp. ZF10 with ethyl acetate, and purified by silica gel column chromatography and HPLC.
