HF50731 (HF-50731) is a novel potent, selective CXCR4 antagonist with Ki of 19.8 nM in the CXCR4 competitive binding assay.
HF50731 significantly inhibited SDF-1α-induced calcium mobilization (IC50=621 nM) and cell migration, and blocked HIV-1 infection via antagonizing CXCR4 coreceptor function (IC50=1.5 uM).
The structure-activity relationship analysis demonstrated that HF50731 could primarily occupy the minor subpocket of CXCR4 and partially bind in the major subpocket by interacting with residues W94, D97, D171, and E288.
