Dysregulation of the CXCL12/CXCR4 axis is involved in numerous pathological conditions such as HIV infection, inflammation and cancer. Herein, we report the design, synthesis, and characterization of novel CXCR4 antagonists based on cyclic amine scaffolds. Compound 24 was identified as a potent CXCR4 receptor antagonist (competitive inhibition of 12G5 binding, IC50=24 nM; functional inhibition of CXCL12‐induced
趋化因子受体CXCR4及其天然配体CXCL12(也称为基质细胞衍生因子-1或SDF-1)调节广泛的生理功能。CXCL12 / CXCR4轴的失调涉及许多病理状况,例如HIV感染,炎症和癌症。在本文中,我们报告了基于环胺骨架的新型CXCR4拮抗剂的设计,合成和表征。化合物24被确定为有效的CXCR4受体拮抗剂(竞争性抑制12G5结合,IC 50 = 24 nM;功能性抑制CXCL12诱导的胞质钙增加,IC 50 = 0.1 nM)。另外,化合物24在基质胶侵袭试验中有效抑制了CXCR4 / CXCL12介导的趋化性中的细胞迁移。X射线晶体学阐明了化合物24的绝对构型。
