cancer cells migration. These pleiotropic roles make CXCR4 an attractive target to mitigate human disorders. Here a new class of symmetrical polyamines was designed and synthesized as potential small molecule CXCR4 antagonists. Among them, a representative compound 21 (namely HF50731) showed strong CXCR4 binding affinity (mean IC50 = 19.8 nM) in the CXCR4 competitive binding assay. Furthermore, compound
CXCR4是一种经过深入研究的1型人类免疫缺陷病毒(HIV-1)进入的共受体,它认识到其同源配体SDF-1α(也称为CXCL12),它起着许多重要作用,包括调节免疫细胞,控制造血干细胞和指导癌细胞迁移。这些多效作用使CXCR4成为缓解人类疾病的诱人靶标。在这里,设计并合成了一类新型的对称多胺,作为潜在的小分子CXCR4拮抗剂。其中,代表性化合物21(即HF50731 )在CXCR4竞争性结合测定中显示出强的CXCR4结合亲和力(平均IC 50=19.8nM)。此外,化合物21可以显着抑制SDF-1α诱导的钙动员和细胞迁移,并通过拮抗CXCR4共受体功能阻止HIV-1感染。进行了结构活性关系分析,定点诱变和分子对接,以进一步阐明化合物21的结合方式,表明化合物21可以主要占据CXCR4的次要亚型,并通过与残基相互作用而部分结合在主要的次要空间中。 W94,D97,D171和E288。我们的
