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.

A bulk enabling synthesis of the CCR-5 receptor antagonist, Maraviroc (UK-427,857) (1), is presented. Synthesis of the three key fragments, β-amino ester 3, 4,4-difluorohexanecarboxylic acid (2), and 1,3,4-triazole-substituted tropane fragment 4 are described. Coupling strategies for these fragments are discussed and described, including synthetic challenges, protection strategies, impurity generation

Bivalent ligands which bind to MOR-CCR5 heterodimers are provided. The bivalent ligands comprise two discrete pharmacophores, naltrexone and maraviroc, linked by a spacer and bind to MOR-CCR5 heterodimers, e.g. at the surface of a cell. The bivalent ligands are useful in assays to detect MOR-CCR5 heterodimers, as therapeutic agents to prevent and/or treat diseases characterized by the presence of MOR-CCR5 heterodimers.
