MIV-247是选择性的组织蛋白酶S(cathepsinS)抑制剂，对人，小鼠和食蟹猴组织蛋白酶S的Ki值分别为2.1，4.2和7.5nM。
MIV-247 is a selective cathepsin S inhibitor with Kis of 2.1, 4.2 and 7.5 nM for human, mouse and cynomolgus monkey cathepsin S, respectively.
Oral administration of MIV-247 (100-200 µmol/kg) dose-dependently attenuates mechanical allodynia by up to approximately 50% reversal when given as a single dose or when given twice daily for 5 days. Cathepsin S inhibition with MIV-247 exerts significant antiallodynic efficacy alone, and also enhances the effect of gabapentin and pregabalin without increasing side effects or inducing pharmacokinetic interactions[1].

Animal experiment: | Mice[1]MIV-247 is administered via oral gavage to Male C57BL/6 mice (20-30 g) at a dose volume of 5 ml/kg at doses up to 200 μmol/kg. In the PK studies, seven blood samples (20 μL) are drawn from the lateral saphenous vein of each mouse at 15 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, 5 hours, and 7 hours postdose[1]. |
