Styrylheterocycles as a novel class inhibitor of cyclooxygenase-2-mediated prostaglandin E 2 production
摘要:
The inhibitory effects of a series of styrylheterocycles on the production of cyclooxygenase-2-mediated prostaglandin E, (PGE(2)) were evaluated in lipopolysaccharide-stimulated RAW264.7 murine macrophages. A new series of potential inhibitors, including 3-[2-(4-methoxy-phenyl)-vinyl]-thiophene, have been identified, thus providing novel chemical leads for the further development of potential inhibitors in this capacity. The suppression of COX-2 mRNA expression by the active styryl heterocycles, in part, was involved in the inhibitory activity against the overproduction of PGE(2).(C) 2004 Elsevier Ltd.

A series of trans-stilbene derivatives containing a 3,5-dimethoxyphenyl moiety were prepared through a new efficient solution phase synthetic pathway, and their inhibitory activities were evaluated on human cytochrome P450s (CYP) 1A1, 1A2, and 1B1 to find a potent and selective CYP1B1 inhibitor. We found that a substituent at the 2-position of the stilbene skeleton plays a very important role in discriminating between CYP1As and CYP1B1. Among the compounds tested, the most selective and potent CYP1B1 inhibitor was 2,3',4,5'-tetramethoxystilbene, Compound 7j, 2-[2-(3,5-dimethoxy-phenyl)vinyl]thiophene, showed greater inhibitory activities but had a lower selectivity toward all of the CYP1s tested.

A stilbene derivative having cytochrome P450 1B1 inhibitory activity, pharmaceutically acceptable salt thereof, method for preparing the same, and composition including the same are disclosed. The stilbene derivative is a strong and selective inhibitor of cytochrome P450 1B1, thereby to decrease or prevent chemical carcinogenesis in mammals, in particular the development of a breast cancer, and can be used as a pharmaceutical tool to elucidate the function of cytochrome P450.
