[Anti-inflammatory properties of noopept (dipeptide nootropic agent GVS-111)].
It is established that single intravenous (0.5 and 5 mg/kg, p.o.) or single peroral (10, 50, 100 mg/kg) and prolonged peroral (5 mg/kg, over 10 days) administration of noopept produces a dose-dependent inhibition of the model inflammatory response to concanavaline A in CBA mice. Intravenously injected (5 mg/kg) noopept suppressed the acute nonimmune carrageenan-induced foot inflammation in rats by 62.2% within 3 h. The most pronounced antiinflammatory effect of dipeptide was observed on the model of adjuvant arthritis in rats, where the drug administered over 25 days in a daily dose of 0.5 mg/kg (i.m.) or 5 mg/kg (p.o.) significantly reduced the chronic immune inflammation (on the 12th day, by 94.0 and 74.1%, respectively). The in vitro experiments with neutrophilic leukocytes of F1(CBA.C57BL/6) mice treated with noopept in a single dose of 5 mg/kg (i.v.) showed a 5- to 6-fold suppression of the hemiluminescence stimulated by opsoinized zymosan or phorbolmyristate acetate. It is suggested that the antiinflammatory activity of noopept is probably related to its antioxidant properties.
