N-imidazolyl derivatives of the napththalene and chroman rings as thromboxane A2 synthase inhibitors
摘要:
A series of N-imidazol-1-yl derivatives of 1,2-dihydronaphthalene, 1,2,3,4-tetrahydronaphthalene, 2H-1-benzopyran and some related compounds were synthesized and tested as inhibitors of thromboxane A2 synthase in ex vivo experiments with orally treated rats. Some compounds showed good activity which was confirmed in experiments in vitro in rabbit whole blood. Some structural requirements for significant TxA2 synthase inhibitory activity are discussed. The selected 5,6-Dihydro-7-(H-1-imidazol-1-yl)-2-naphthalene-carboxylic acid (compound 7) was conformationally analysed using the Sybyl molecular model system in comparison with dazoxiben. Compound 7 was further pharmacologically investigated and on the basis of its interesting activities in vitro, ex vivo and in vivo and its low toxicity was selected for clinical investigation.
