Abstract:
AIM: To study the effect of the four alkaloids of Sophora Alopecuroides On cycloxygenase(COX) activities in vitro. METHODS: The effect of matrine, oxymatrine sophocarpine and sophoridine on COX2 and COX1 activity were evaluated by the content of Prostaglandin E_2(PGE_2) and 6-Keto-PGF_~1a , respectively. The PGE_2 came from exogenous AA in cultured mouse peritoneal macrophage supernatants induced by lipopolysaccharide(LPS) 1 ug?mL~-1 was measured with radioimmunoassay(RIA) method using ~ 3H-labelled PGE_2. The 6-Keto-PGF_~1a from exogenous AA in cultured mouse peritoneal macrophage supernatants induced by calcium ionophore A23187 1 ?mol?L~-1 was measured with RIA method using~125 I-labelled 6-Keto-PGF_~1a . RESULTS: The COX2 activities were markedly inhibited in a dose dependent manner by oxymatrine, sophocarpine and sophoridine, Respectively. Excluding the sophoridine, all the other three alkaloids of Sophora Alopecuroids obviously suppressed the activities of COX1, respectively. CONCLUSION: The in vitro results show that oxymatrine, sophocarpine and sophoridine may have the significant specific inhibitory action for COX2, in contrase, matrine may be COX1 selective inhibitor.
