title: Pepticinnamins, new farnesyl-protein transferase inhibitors produced by an actinomycete. I. Producing strain, fermentation, isolation and biological activity.
abstract: Pepticinnamins A, B, C, D, E and F, a family of farnesyl-protein transferase (FPT) inhibitors were isolated from the fermentation broth of Streptomyces sp. OH-4652. These inhibitors were purified from whole broth by extraction with chloroform, followed by silica gel column chromatography, Sephadex LH-20 chromatography and reverse phase HPLC. Among these, pepticinnamin C showed the most potent inhibition (IC50-100 nM).
