SCH 32615 is an enkephalinase (the enzymes responsible for the degradation of endogenous enkephalins) inhibitor. SCH 32615 can enhance surgery- and pregnancy-induced analgesia in mice[1][2].
SCH 32615 blocks the degradation of Met5-enkephalin by isolated enkephalinase, with the Ki of 19.5 nM[3].
SCH 32615 (150 mg/kg; s.c.) enhances surgery activated endogenous analgesia in mice[1].
