AMD 3465 also potently inhibits the replication of X4 HIV strains (IC50: 1-10 nM). However, it has no effect on CCR5-using (R5) viruses. AMD 3465 (GENZ-644494) is a potent antagonist of CXCR4, inhibits binding of 12G5 mAb and CXCL12AF647 to CXCR4, with IC
CXCR4 antagonist 8 (Compound 3) is a potent inhibitor of CXCR4. It demonstrates an IC50 value of 57 nM in CXCR4 antagonism. In addition, it effectively inhibits the increase in cytosolic calcium induced by CXCL12 with an IC50 value of 0.24 nM. Furthermore, Compound 3 shows efficacy in the inhibition of CXCL12 CXCR4-mediated cell migration [1].
CXCR4 antagonist 5 (compound 23), a potent CXCR4 antagonist, exhibits high inhibition efficacy against CXCR4 with an IC50 value of 8.8 nM. It effectively suppresses CXCL12-induced cytosolic calcium increase (IC50 = 0.02 nM) and hinders CXCR4 CXCL12-mediated chemotaxis. Moreover, Compound 23 demonstrates favorable physicochemical properties and in vitro safety profiles, exhibiting only marginal to moderate inhibition of CYP isozymes and hERG [1].
CXCR4 antagonist 6 (compound 46) is a highly potent inhibitor of CXCR4 with an IC50 value of 79 nM. It effectively inhibits the cytosolic calcium flux induced by CXCL12, achieving an IC50 of 0.25 nM. Moreover, CXCR4 antagonist 6 demonstrates significant mitigation of cell migration mediated by the CXCL12 CXCR4 interaction. Notably, this compound exhibits remarkable efficacy in a mouse model of cancer metastasis [1].
CXCR4 antagonist 9 (Compound 2) is a potent CXCR4 antagonist displaying an IC50 of 15 nM. It effectively inhibits the cytosolic calcium increase induced by CXCL12, with an IC50 value of 1.3 nM [1].
