Biological Activity for TAK 779

TAK 779 is a potent and selective CCR5 and CCR2 chemokine receptor antagonist (IC50 values = 1 nM and 27 nM, respectively). TAK 779 blocks the binding of macrophage inflammatory protein 1α and 1β to CHO cells (IC50 = 1 nM) and inhibits replication of R5 HIV-1 at 1.6-3.7 nM. In animal models, TAK 779 protects against ischemic brain injury and prevents development of asthma features.
