ABSTRACT
Abstract The interaction of CXCR4 with CXCL12 (SDF‐1) plays a critical role in cancer metastasis by facilitating the homing tumor cells to metastatic sites. Based on our previously published work antagonists, we have synthesized series aryl sulfonamides that inhibit CXCR4/CXCL12 interaction. Analogue bioactivities were assessed binding affinity and Matrigel invasion assays. Computer modeling was employed evaluate selection new analogues docked into X‐ray structure rationalize discrepancies between vitro A lead compound displays nanomolar potency assay (IC 50 =8.0 n M ) (100 % blockade at 10 ). These data demonstrate benzenesulfonamides are unique class inhibitors high potency.
