CCR5, as the major co-receptor for HIV-1 entry, is an attractive novel target for the pharmaceutical industry in the HIV-1 therapeutic area. In this study, based on the structures of maraviroc and 1,4-bis(4-(7-chloroquinolin-4-yl)piperazin-1-yl)butane-1,4-dione (1), which was identified using structure-based virtual screening in conjunction with a calcium mobilization assay, a series of novel small molecule CCR5 antagonists have been designed and synthesized through fragment assembly. Preliminary SARs were obtained, which are in good agreement with the molecular binding model and should prove helpful for future antagonist design. The novel scaffold presented here might also be useful in the development of maraviroc-derived second generation CCR5 antagonists.
CCR5作为HIV-1入侵的主要共受体,是制药工业在HIV-1治疗领域的一个具有吸引力的新型靶点。本研究基于马拉韦罗克和1,4-双(4-(7-氯喹啉-4-基)哌嗪-1-基)丁烷-1,4-二酮(1)的结构,通过片段组装设计并合成了一系列新型小分子CCR5拮抗剂,其中1是通过结构虚拟筛选结合钙动员测定鉴定的。初步的SARs(构效关系)得以获得,这些SARs与分子结合模型吻合良好,有望对未来拮抗剂设计具有指导意义。本文所展示的新型骨架在开发由马拉韦罗克衍生的第二代CCR5拮抗剂中可能还有用武之地。
