Several series of acyl-CoA:cholesterol O-acyltransferase inhibitors were prepared by the stepwise addition of nitrogen, oxygen, and sulfur nucleophiles to N-chlorosulfonyl isocyanate. The (aminosulfonyl)ureas 3-44 were the most potent inhibitors in vitro, with several compounds having IC50 values < 1 microM. Although the other series of compounds were not as potent in vitro, many compounds did display

脲3-44是体外最有效的
抑制剂,几种化合物的IC50值<1 microM。尽管其他系列的化合物在体外效果不佳,但许多化合物在以胆固醇喂养的大鼠中确实显示出良好的体内活性。几种氧磺酰基氨基甲酸酯(包括CI-999、115)在慢性体内筛选中显示出出色的降脂活性,表明在预先建立的高胆固醇血症状态下
胆固醇显着降低。
