ABSTRACT:
This invention provides novel physiologically active substances PF1092A, PF1092B and PF1092C, which can inhibit binding of progesterone to progesterone receptor. These substances were obtained by culturing a fungal microorganism belonging to the genus Penicillium using a medium containing ordinary nutrients for microorganisms and isolating the physiologically active substances PF1092A, PF1092B and PF1092C from the resulting culture mixture by means of solvent extraction, silica gel column chromatography, and the like. Molecular formulae of the novel physiologically active substances PF1092A, PF1092B and PF1092C are C.sub.17 H.sub.20 O.sub.5, C.sub.17 H.sub.20 O.sub.5 and C.sub.15 H.sub.18 O.sub.4, respectively.
