【摘要】:正依折麦布是通过抑制肠道吸收胆固醇的作用机制降低体内胆固醇的首创性药物。1作用靶标人体内的胆固醇来源有两个途径:自身合成和膳食摄取。体内近三分之二的胆固醇是自身合成的,由乙酰辅酶A经30多个酶催化的生化反应生成;其余部分来自于膳食,经肠吸收进入肝脏。负责胆固醇吸收的一个靶标,是酰化辅酶A胆固醇酰基转移酶(acyl-coenzyme A cholesterol acyltransferase,ACAT)。ACAT是微粒体酶,负责将游离胆固醇转变为脂肪酸
[Abstract]:Zhengezebu is the first drug to reduce cholesterol in vivo by inhibiting the absorption of cholesterol in the gut. 1. There are two sources of cholesterol in target human body: self-synthesis and dietary intake. Nearly three-thirds in vivo. Bis cholesterol is self-synthesized, Acetyl coenzyme A is produced by biochemical reaction catalyzed by more than 30 enzymes; the rest comes from diet and is absorbed by intestine into the liver. A target responsible for cholesterol absorption is acyl-coenzyme A cholesterol acyltransferase A acyltransferase Acyltransferase ACATN. ACAT is a microsomal enzyme, and a target for cholesterol absorption is acyl-coenzyme A acyltransferase A acyltransferase A acyltransferase A acyltransferase. Responsible for converting free cholesterol into fatty acids
