anti-HIV activity. Herein, we describe in detail the identification of these lead compounds using a combinatorial chemistry approach. A novel spirodiketopiperazine scaffold was designed on the basis of the concept of the privileged structure of G-protein-coupled receptors (GPCRs). This new framework was obtained in acceptable yield with high purity from the readily prepared isonitrile resin through
我们之前曾报道发现有几种螺二酮哌啶衍生物作为具有抗HIV活性的有效CCR5拮抗剂。在本文中,我们详细描述了使用组合化学方法鉴定这些先导化合物的方法。基于G蛋白偶联受体(GPCR)的优先结构的概念,设计了一种新型的螺二酮哌嗪骨架。通过Ugi反应,顺序转化和环化裂解,可以从容易制备的异腈树脂中以高收率获得可接受的高纯度新骨架。通过测量初始文库中每种化合物对MIP-1alpha刺激的细胞内钙动员的抑制活性,发现了几种化合物显示出适度但有选择性的CCR5拮抗活性。
