TAK-220 是一种选择性的，可口服的 CCR5 拮抗剂，能够抑制 RANTES，MIP-1α 与 CCR5 结合，IC₅₀ 值分别为 3.5 nM 和 1.4 nM，但是对 CCR1，CCR2b，CCR3，CCR4 或者 CCR7 无作用; TAK-220 也可选择性地抑制 HIV-1，在外周单核细胞中，EC₅₀ 值分别为 1.2 nM (HIV-1 KK)，0.72 nM (HIV-1 CTV)，1.7 nM (HIV-1 HKW)，1.7 nM (HIV-1 HNK)，0.93 nM (HIV-1 HTN) 和 0.55 nM (HIV-1 HHA)，EC₉₀ 值分别为 12 nM (HIV-1

TAK-220 is a selective and orally bioavailable CCR5 antagonist, with IC 50 s of 3.5 nM and 1.4 nM for inhibition on the binding of RANTES and MIP-1α to CCR5, respectively, but shows no effect on the binding to CCR1, CCR2b, CCR3, CCR4, or CCR7; TAK-220 also selectively inhibits HIV-1, with EC 50 s of 1.2 nM (HIV-1 KK), 0.72 nM (HIV-1 CTV), 1.7 nM (HIV-1 HKW), 1.7 nM (HIV-1 HNK), 0.93 nM (HIV-1 HTN), and 0.55 nM (HIV-1 HHA), and EC 90 s of 12 nM (HIV-1 KK), 5 nM (HIV-1 CTV), 12 nM (HIV-1 HKW), 28 nM (HIV-1 HNK), 15 nM (HIV-1 HTN), and 4 nM (HIV-1 HHA) in PBMCs.

Solid

MIP-1α-CCR5 1.4 nM (IC50, in CHO cells) RANTES-CCR5

TAK-220 is a selective CCR5 antagonist, with IC50s of 3.5 nM and 1.4 nM for inhibition on the binding of RANTES and MIP-1α to CCR5 in CHO cells, respectively, but shows no effect on the binding to CCR1, CCR2b, CCR3, CCR4, or CCR7. TAK-220 (0-1000 nM) interacts with CCR5 but not with RANTES and inhibits the CCR5-mediated Casup>2+ signaling. TAK-220 inhibits R5 HIV-1 (JR-FL) envelope-mediated membrane fusion, with an IC50 value of 0.42 nM, but does not alter X4 HIV-1 (HXB2) envelope-mediated membrane fusion. TAK-220 also selectively inhibits HIV-1, with EC50s of 1.2 nM (HIV-1 KK), 0.72 nM (HIV-1 CTV), 1.7 nM (HIV-1 HKW), 1.7 nM (HIV-1 HNK), 0.93 nM (HIV-1 HTN), and 0.55 nM (HIV-1 HHA), and EC90s of 12 nM (HIV-1 KK), 5 nM (HIV-1 CTV), 12 nM (HIV-1 HKW), 28 nM (HIV-1 HNK), 15 nM (HIV-1 HTN), and 4 nM (HIV-1 HHA) in PBMCs.
