Bioactivity | Rivastigmine tartrate (ENA 713; SDZ-ENA 713) is an orally active and potent cholinesterase (ChE) inhibitor and inhibits butyrylcholinesterase (BChE) and acetylcholinesteras (AChE) with IC50s of 0.037 μM, 4.15 μM, respectively. Rivastigmine tartrate can pass the blood brain barrier (BBB). Rivastigmine tartrate is a parasympathomimetic or cholinergic agent used for the research of mild to moderate dementia of the Alzheimer's type and dementia due to Parkinson's disease[1][2]. |
Target | IC50: 0.037 μM (BChE) and 4.15 μM (AChE) |
Invitro | Rivastigmine tartrate (ENA 713; 1 µM; 24 hours) reduces LPS (2.5 µg/ml)-induced TNF-α and IL-6 by 50% and 46% combined with carbachol (10 µM), respectively and does not cause any significant reduction in pro-inflammatory cytokines [3]. Rivastigmine tartrate (1 µM), carbachol (10 µM), or a combination of both drugs, does not have a cytotoxic effect on activated cells[3]. |
In Vivo | Rivastigmine tartrate (ENA 713; 0.5-2.5 mg/kg; IP; 60 min before the tests) significantly and dose-dependently improved the behavioral impairments caused by Aluminum (HY-B1521)[4]. Rivastigmine (0.5, 1 mg/kg/day; s.c; for 8 days) reduces by about 50% and 60% respectively, the concentration of IL-6 but not those of TNF-α and IL-1β in BALB/c OlaHsd male mice aged 8-9 weeks weighing 200–250 g with acute colitis[3]. Rivastigmine (1 mg/kg), but not (0.5 mg/kg), partially antagonized colon shrinkage and completely prevented bleeding. Treatment with rivastigmine (0.5 mg/kg) causes little change in these pathological manifestations, but rivastigmine (1 mg/kg) causes a partial restoration of the structure of the crypts and a reduction in sub-mucosal edema and cell infiltration. Rivastigmine (1 mg/kg) causes a 4.7% reduction in body weight at the end of the experiment[3]. Animal Model: |
