alkyl or aryl groups were substituted on the carbon alpha to the phosphonate function in amide compounds to see whether substituted phosphonates can act as a secondary pharmacophore. A tert-butyl group (16) on the alpha carbon was found to yield most potent inhibition on the target enzyme. A 4-50-fold drop in inhibition was induced by other substituents such as aryls, substituted aryls, cycloalkyls, and
研究了作为人类可溶性环氧水解酶(sEH)抑制剂的酰胺-膦酸酯衍生物的构效关系。首先,将一系列烷基或芳基基团在碳原子α上取代为酰胺化合物中的膦酸酯官能团,以查看取代的膦酸酯是否可以充当次级药效团。发现α碳上的叔丁基(16)对目标酶产生最有效的抑制作用。其他取代基(如芳基,取代的芳基,环烷基和烷基)诱导抑制作用降低4-50倍。然后,O-取代基在膦酸酯官能团上的修饰表明,二乙基(16和23)对于抑制其他更长的烷基或取代的烷基是优选的。在具有优化的二乙基膦酸酯部分和烷基取代的酰胺化合物(如金刚烷(16),四氢萘(31)或金刚烷甲烷(36))中,获得了高度有效的抑制作用。另外,所得的有效的酰胺-膦酸酯化合物具有合理的水溶性,这表明酰胺抑制剂中的取代的膦酸酯对于抑制人sEH的效力和作为辅助药效团的水溶性均是有效的。
