The preparation of a series of 2-(1H-imidazol-1-ylmethyl)-substituted carboxylic acids of benzo[b]furan, benzo-[b]thiophene, indole, and naphthalene is described. All compounds showed a similar level of activity as TxA2 synthetase inhibitors in vitro, having IC50 values between 1 and 7 X 10(-8) M. In the cases examined, compounds had, at most, only negligible activity against PGI2 synthetase, cyclooxygenase
描述了苯并[b]呋喃,苯并-[b]噻吩,吲哚和萘的一系列2-(1H-咪唑-1-基甲基)取代的羧酸的制备。在体外,所有化合物均显示出与TxA2合成酶抑制剂相似的活性水平,IC50值为1至7 X 10(-8)M。在所检查的情况下,化合物对PGI2合成酶,环加氧酶的活性至多仅微不足道。和类固醇11β-羟化酶。苯并[b]噻吩通常在体内表现出最大的效力,在向有意识的狗口服施用0.5 mg / kg后的6小时内,化合物72、73和75几乎完全抑制了血栓烷的产生。在73和75的情况下,24小时后血栓烷的产生仍被抑制了80%。
