Cholesteryl ester transfer protein (CETP) is a potential target for cardiovascular disease therapy as inhibition of CETP leads to increased HDL-C in humans. Based on the structure of Merck's biphenyl CETP inhibitor, we designed novel N,N-substituted-cycloalkenyl-methylamine scaffold derivatives by utilizing core replacement and conformational restriction strategies. Consequently, twenty-eight compounds
胆固醇酯转移蛋白(CETP)是心血管疾病治疗的潜在目标,因为抑制CETP会导致人类HDL-C升高。基于Merck的联苯CETP抑制剂的结构,我们利用核心置换和构象限制策略设计了新型的N,N-取代的环烯基-甲胺骨架衍生物。因此,合成了28种化合物并评估了其对CETP的抑制活性。他们的初步结构-活性关系(SARs)研究表明,极性取代基在A部分中具有耐受性,而环己烯5-位的疏水烷基对效能至关重要。其中,化合物17a带有N-(5-吡唑基-嘧啶-2-基)-环烯基-甲胺支架在体外表现出出色的CETP抑制活性(IC 50 = 0.07μM)。此外,它在SD大鼠中显示出可接受的药代动力学特征,在高脂喂养的仓鼠中有效地增加了HDL-C。
