A novel series of CXCR4 antagonists with substituted piperazines as benzimidazole replacements is described. These compounds showed micromolar to nanomolar potency in CXCR4-mediated functional and HIV assays, namely inhibition of X4 HIV-1IIIB virus in MAGI-CCR5/CXCR4 cells and inhibition of SDF-1 induced calcium release in Chem-1 cells. Preliminary SAR investigations led to the identification of a
描述了具有取代的哌嗪作为苯并咪唑替代物的一系列新的CXCR4拮抗剂。这些化合物在CXCR4介导的功能和HIV检测中显示出微摩尔至纳摩尔的效价,即在MAGI-CCR5 / CXCR4细胞中抑制X4 HIV-1 IIIB病毒和在Schem- 1细胞中抑制SDF-1诱导的钙释放。SAR的初步研究导致鉴定出一系列N-芳基哌嗪为最有效的化合物。结果表明,SAR表示芳香环的类型和位置,以及接头和立体化学的类型对于活性均很重要。对几种先导化合物进行分析表明,一种(49b)降低了对CYP450和hERG的敏感性,同时考虑了SDF-1和HIV效力(6–20 nM)时获得了最佳的总体特征。
