A structure-activity relationship study of potent TIQ15-derived CXCR4 antagonists is reported. In this investigation, the TIQ15 side-chain was constrained to improve its drug properties. The cyclohexylamino congener was found to be a potent CXCR4 inhibitor (IC = 33 nM in CXCL12-mediated Ca flux) with enhanced stability in liver microsomes and reduced inhibition of CYP450 (2D6). The improved CXCR4 antagonist has potential therapeutic application as a single agent or combinatory anticancer therapy.
报道了强效TIQ15衍生的CXCR4拮抗剂的构效关系研究。在本研究中,对TIQ15侧链进行了限制以改善其药物性质。发现环己基氨基类似物是一种强效的CXCR4抑制剂(在CXCL12介导的钙流中IC = 33 nM),在肝微粒体中稳定性增强,对CYP450(2D6)的抑制作用降低。改进后的CXCR4拮抗剂作为单一药物或联合抗癌疗法具有潜在的治疗应用价值。
