The synthesis and the biological evaluation of a new series of medetomidine analogs are reported. The substitution pattern at the phenyl ring of the tetralin analogs had a distinct influence on the alpha 2-adrenoceptor binding affinity. 4-Methylindan analog 6 was the most potent alpha 2-adrenoceptor binding ligand among these 4-substituted imidazoles, and its alpha 2-adrenoceptor selectivity was greater
报道了一系列新的美托咪定类似物的合成和生物学评估。四氢萘类似物的苯环上的取代模式对α2-肾上腺素受体的结合亲和力有明显的影响。在这些4-取代的咪唑中,4-甲基茚满类似物6是最有效的α2-肾上腺素受体结合配体,并且其α2-肾上腺素受体选择性大于5-甲基四氢化萘类似物4c。配体药效基团和受体建模相结合,以根据配体-受体相互作用合理化咪唑类似物的α2-肾上腺素受体结合数据。从本研究和以前的研究中可以明显看出,结构与活性之间的关系已通过α2肾上腺素受体的结合位点模型进行了定性的合理化。
