Comparative effect of the prolyl endopeptidase inhibitors, benzyloxycarbonyl-prolyl-prolinal and benzyloxycarbonyl-methionyl-cyanopyrrolidine, on the acute exudative inflammation and visceral pain in mice
Abstract:A selective prolyl endopeptidase (PEP) inhibitor benzyloxycarbonyl-prolyl-prolinal (IC50 = 1,61±0,12 nmol/l) and a nonselective PEP inhibitor benzyloxycarbonyl-methionyl-cyanopyrrolidine (IC50 = 2,01±0,14 nmol/l) exhibit a comparable antiexudative effect at single doses of 2 mg/kg and 5 mg/kg (intraperitoneally) in outbred mice with peritonitis induced by 1% acetic acid. However, only benzyloxycarbonyl-methionyl-cyanopyrrolidine at a dose of 5 mg/kg reduces acetic acid induced pain in animals.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
