cycloalkylcarbonyl derivatives. Certain other acidic sulfonamides, such as sulfonylcarbamates and disulfimides also displayed high affinity for the AT1 receptor. In addition, AT2 binding for some of these compounds was increased by as much as 1000-fold over the corresponding tetrazole (e.g., AT2 IC50 17 nM for the tert-butyl sulfonylcarbamate 92). When evaluated for inhibition of the AII pressor response, the benchmark
几个系列的2,4-二氢-2,4,5-三取代的3H-1,2,4-三唑-3-酮在联苯-4-基甲基的2'-位上被四唑的酸性磺酰胺取代制备N4链并作为血管紧张素II(AII)拮抗剂进行测试。三唑啉酮环上的优选取代基是在C5处的正丁基和在N2处的2-(三氟甲基)苯基。对于多种酰基磺酰胺,包括芳酰基,杂芳酰基和环烷基羰基衍生物,观察到AT1受体亚型的亚纳摩尔IC50值。某些其他酸性磺酰胺,如磺酰氨基甲酸酯和二硫化亚胺也对AT1受体表现出高亲和力。另外,这些化合物中某些化合物的AT2结合量比相应的四唑增加了1000倍(例如,叔丁基磺酰基氨基甲酸酯92的AT2 IC50 17 nM)。当评估抑制AII升压反应时,基准苯甲酰磺酰胺9(L-159,913)在几种物种中均有效,在有意识的恒河猴中优于氯沙坦(1a)。随后的几种类似物,包括2-氯苯甲酰基(18),(3-氯噻吩-2-基)羰基(51),((S)-2,2
