Application

TAK-779 has been used to inhibit CC chemokine ligand 5 (CCL5)– C-C chemokine receptor type 5 (CCR5) interaction in vitro in natural killer (NK) cytotoxicity assay. It has also been used as a blocker of CCR5 to study its effects and to evaluate the opening of the Panx-1 channels on peripheral blood mononuclear cells (PBMCs) isolated from human immunodeficiency virus (HIV)-infected individuals.

Biochem/physiol Actions

TAK-779 is a potent, dual antagonist at chemokine receptors C-C chemokine receptor type 2 (CCR2) and C-C chemokine receptor type 5 (CCR5) with IC⁵⁰ = 1.4 nM at CCR5 and 2.3 nM at CCR2. Antagonists of both CCR2 and CCR5 such as TAK-779 have been investigated for treatment of viruses, rheumatoid arthritis, multiple sclerosis, and cancer. CCR5 is particularly targeted for anti-HIV therapy, since HIV entry into cells requires chemokine coreceptors CCR5 and C-X-C motif chemokine receptor 4 (CXCR4).

TAK-779 inhibits human immunodeficiency virus (HIV) entrance by blocking the C-C chemokine receptor type 5 (CCR5). It also impairs the formation of atherosclerotic lesions by preventing T-helper 1 cells from entering the plaque. TAK-779 possesses anti-immunogenic properties. In an arthritis model, it could prevent the inflow of CCR5- and chemokine (C-X-C motif) receptor 3 (CXCR3)-positive T cells into inflamed joints. In mice, TTAK-779 protects the brain from focal cerebral ischemia.
