| Bioactivity | Vicriviroc maleate (SCH-417690 maleate; SCH-D maleate) is a potent, selective, oral bioavailable and CNS penetrated antagonist of CCR5, with a Ki of 2.5 nM, and also inhibits HIV-1 in PBMC cells, with IC90s of 3.3 nM (JrFL), 2.8 nM (ADA-M), 1.8 nM (301657), 4.9 nM (JV1083) and 10 nM (RU 570). |
| Invitro | Vicriviroc maleate (SCH-417690 maleate; SCH-D maleate) is a potent, selective and oral bioavailable inhibitor of CCR5, with a Ki of 2.5 nM, and also inhibits HIV-1 in PBMC cells, with IC90s of 3.3 (JrFL), 2.8 (ADA-M), 1.8 (301657), 4.9 (JV1083) and 10 nM (RU 570). In addition, Vicriviroc maleate shows a mean IC50 and IC90 of 0.45 nM and 4 nM for a panel of HIV isolates, and has weak activity against hERG activity (IC50, 5.8 μM)[1]. Vicriviroc maleate inhibits chemotactic response to MIP-1α with IC50 values below 1 nM, and suppresses RANTES-induced signaling with a mean IC50 of 4.2 ± 1.3 nM. Vicriviroc maleate potently suppresses all the viral isolates tested, with geometric mean EC50s of 0.04-2.3 nM and IC90s of 0.45-18 nM[2]. |
| In Vivo | Vicriviroc maleate (SCH-417690 maleate; SCH-D maleate; 10 mg/kg) has good oral availablity in rats and monkeys, with no acute CNS or GI effects in rats[1]. |
