Prucalopride in the presence of IBMX on the S2/S1 ratio of electrically induced total tritium outflow. Tissues were stimulated twice (S1 and S2; 1 millisecond, 15 V, 4 Hz, 2 minutes); IBMX was added 36 minutes and prucalopride 15 minutes before S2. Mean S2/S1±SEM; one‐way ANOVA followed by Bonferroni corrected t test with ns not significant, *P<.05 and ***P<.001.

Prucalopride induces contractions in a concentration-dependent manner with pEC50 of 7.5. Prucalopride (1 mM) significantly amplifies the rebound contraction of the guinea-pig proximal colon after electrical field stimulation. Prucalopride induces relaxation of the rat oesophagus preparation of rat oesophagus tunica muscularis mucosae with pEC50 of 7.8, yielding a monophasic concentration–response curve.  Prucalopride (0.1 μM) concentration-dependently increases the amplitude of submaximal cholinergic contractions and of acetylcholine release induced by electrical field stimulation in pig gastric circular muscle, and the effect is induced and enhanced IBMX (10 μM).  Prucalopride (1 μM) significantly enhances the electrically induced cholinergic contractions in pig descending colon, and the facilitating effect is significantly enhanced by Rolipram. 
|In vivo||Prucalopride alters colonic contractile motility patterns in a dose-dependent fashion by stimulating high-amplitude clustered contractions in the proximal colon and by inhibiting contractile activity in the distal colon of fasted dogs. Prucalopride also causes a dose-dependent decrease in the time to the first giant migrating contraction (GMC); at higher doses of prucalopride, the first GMC generally occurres within the first half-hour after treatment. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
