Product Data
Biological target:
Mepenzolate Bromide is a muscarinic antagonist.
In vitro activity:
In this study’s attempt to isolate the pharmacologically active ingredients in the aqueous extracts of Mareya micrantha, this study has selected the contractions of the longitudinal muscle of the isolated guinea-pig ileum preparation as a pharmacological marker to monitor retention of pharmacological activity during the chromatographic separation. Mepenzolate (10(-8)-10(-5) M), a specific muscarinic receptor antagonist, similarly antagonized contractions elicited by the aqueous extracts suggesting that the cholinergic ingredient(s) in the extract are acting at the muscarinic receptors of the preparation.

In vivo activity:
The present study aimed at exploring the effect of niacin on experimental colitis in rats as well as throwing some light on the ability of niacin to modulate angiogenesis which plays a crucial role of in the pathogenesis of inflammatory bowel disease. Mepenzolate bromide, a GPR109A receptor blocker, abolished the beneficial effects of niacin on body weight, colon wet weight as well as colonic levels of MPO and VEGF.
