TAK-779 is a highly potent and selective nonpeptide CCR5 antagonist with a IC50 value of 1.4 nM in the binding assay. TAK-779 also inhibits the replication of macrophage (M)-tropic HIV-1 (Ba-L strain) in both MAGI-CCR5 cells and PBMCs with EC50 values of 1.2 and 3.7 nM, respectively.

Synonyms: Takeda 779
