2- (1, t- and c-4-Dialkylcyclohex-r-1-yl) -2-oxoethyl arenesulfonates, 2- (4, 4-dialkylcyclohex-1-yl) -2-oxoethyl arenesulfonates and related compounds were synthesized and evaluated for esteraseand chymotrypsin-inhibitory activities in vitro and for hypolipidemic effect in vivo. The transisomers of 2- (1, 4-dialkylcyclohex-1-yl) -2-oxoethyl arenesulfonates showed much more potent esterase-inhibitory action (about 13 to 6200 times) than the cis-isomers as well as more potent hypolipidemic action (about 1.5 to 10 times) but the chymotrypsin-inhibitory actions of the two isomers were similarly low. On the other hand, the 2-oxoethyl arenesulfonates having a 4, 4- disubstituted cyclohexane ring mostly exhibited potent esterase-inhibitory action (order of IC50; 10-8 to 10-9M) and marked hypolipidemic effect (78% to 95% reductions of plasma triglyceride).
合成了 2-(1,t- 和 c-4-二烷基环己-r-1-基)-2-氧代乙基异辛烷磺酸盐、2-(4,4-二烷基环己-1-基)-2-氧代乙基异辛烷磺酸盐和相关化合物,并对其体外酯酶和糜蛋白酶抑制活性以及体内降血脂作用进行了评估。2-(1, 4-二烷基环己-1-基)-2-氧代乙基甲磺酸酯的反式异构体显示出比顺式异构体更强的酯酶抑制作用(约 13 至 6200 倍)以及更强的降血脂作用(约 1.5 至 10 倍),但这两种异构体的糜蛋白酶抑制作用同样较低。另一方面,具有 4,4- 二取代环己烷环的 2-氧代乙基异磺酸盐大多具有强效的酯酶抑制作用(按 IC50 的顺序排列;10-8 至 10-9M)和明显的降血脂作用(血浆甘油三酯降低 78% 至 95%)。
