In vitro study | AMG 517 inhibits CAP-(500 nM), acid (pH 5.0), or heat (45°C) induced |
In vivo study | AMG 517 oral treatment, resulting in increased plasma concentrations, this effect exists in a dose-dependent manner, also reduce the number of clot withdrawal induced by Capsaicin treatment, this effect also exists in a dose-dependent manner. The lowest effective dose (MED) for AMG 517 was found to be 0.3 mg/kg based on the statistically significant difference in the number of withdrawal between the control group and the Capsaicin group. The corresponding plasma concentration of AMG 517 is 90 to 100 ng/mL. Treatment with AMG 517(3 mg/kg) for 24 hours significantly reduced Capsaicin-induced withdrawal. AMG 517 acts on CFA pain model to inhibit thermal hyperalgesia. AMG 517 acts in rodents, dogs and monkeys, but not in TRPV1 knockout mice, causing hyperthermia. Interestingly, TRPV1 selective antagonist-induced hyperthermia was attenuated by repeated administration of these antagonists to rats, dogs, and monkeys, as well as TRPV1 knockout mice, without a decrease in body temperature. |
