cancer metastasis by facilitating the homing of tumor cells to metastatic sites. Based on our previously published work on CXCR4 antagonists, we have synthesized a series of aryl sulfonamides that inhibit the CXCR4/CXCL12 interaction. Analogue bioactivities were assessed with binding affinity and Matrigel invasion assays. Computer modeling was employed to evaluate a selection of the new analogues docked
CXCR4 与 CXCL12 (SDF-1) 的相互作用通过促进肿瘤细胞归巢至转移部位而在癌症转移中发挥关键作用。基于我们之前发表的CXCR4拮抗剂工作,我们合成了一系列抑制CXCR4/CXCL12相互作用的芳基磺酰胺类药物。通过结合亲和力和基质胶侵袭测定评估类似物的生物活性。采用计算机建模来评估对接至 CXCR4 X 射线结构的新类似物的选择,并合理化亲和力与基质胶体外测定之间的差异。先导化合物在结合亲和力测定 (IC 50 =8.0 n M ) 和基质胶侵袭测定(10 n M时 100 % 阻断侵袭)中显示出纳摩尔效力。这些数据表明苯磺酰胺是一类独特的高效 CXCR4 抑制剂。

(PPI) has become a promising drug target for several oxidative stress-related and inflammatory diseases including pulmonary fibrosis, chronic obstructive pulmonary disorder (COPD) and cancer chemoprevention. For the development of a potential therapeutic agent, drug-like properties and potency are important considerations. In this work, we focused on the modification of 4 as a lead through a molecular
