Minesapride
Minesapride (DSP-6952 free base) is an orally active, selective 5-HT4 receptor partial agonist. Minesapride enhances gastrointestinal motility, colonic transit and defecation function, and inhibits visceral hypersensitivity. Minesapride does not inhibit/induce cytochrome P450 isozymes, has no significant affinity for hERG, and does not trigger the risk of cardiac ischemia via coronary vasoconstriction. Minesapride can be used in research related to constipation-predominant irritable bowel syndrome, chronic constipation, atonic constipation, spastic constipation, functional constipation and functional dyspepsia.
For research use only. We do not sell to patients.

Biological Activity
|
5-HT4 Receptor |
Minesapride exhibits no inhibitory or inductive activity against cytochrome P450 isozymes in in vitro assays[1].
Minesapride shows no significant binding affinity for the hERG cardiac potassium channel in in vitro experiments[1].
Minesapride shows no significant binding affinity for 5-HT1B, 5-HT1D or 5-HT2A receptors in in vitro assays[1].
Minesapride binds to cell membranes of CHO cells stably transfected with human 5-HT4 (a), 5-HT4 (b), and 5-HT4 (c) receptors, as well as to cell membranes of guinea pig striatal tissues, with a Ki range of 51.9-95.3 nM[2].
Minesapride binds tightly to 5-HT4 (a), 5-HT4 (b), and 5-HT4 (c) receptors (with Ki values of 66.9, 51.9, and 95.3 nM, respectively) as well as guinea pig striatal 5-HT4 receptors (Ki = 63.1 nM)[4].
Minesapride induces concentration-dependent contractions in distal colonic LMMP preparations of guinea pigs, with an EC50 of 271.6 nM and an intrinsic activity of 57% relative to 5-HT[4].
Minesapride (10-100 μM) inhibits hERG currents in hERG-transfected CHO-K1 cells, with an IC50 of 65.4 μM[4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Minesapride (0.3-10 mg/kg; i.g.) dose-dependently enhances colonic transit rate in guinea pigs via activation of 5-HT4 receptors, with significant effects seen at doses of 3 mg/kg and 10 mg/kg[2].
Minesapride (0.3-10 mg/kg; p.o.) dose-dependently increases fecal wet weight in mice without altering fecal fluid content, indicating enhanced defecation without diarrhea[2].
Minesapride (0.03-3 mg/kg; p.o.) dose-dependently improves Clonidine (HY-12721)-induced atonic constipation in mice, with an ED50 of 0.429 mg/kg[2].
DSP-6952 (6-180 mg/kg; p.o.; single dose) does not affect ECG parameters or blood pressure up to 180 mg/kg p.o. in conscious cynomolgus monkeys, but causes a transient, dose-dependent increase in heart rate that is significant at 180 mg/kg p.o[4].
