5-HT4 Receptor 7.7 (pKi) |
Velusetrag (10 pM-100 μM) concentration-dependently increases the cAMP in HEK-293 cells stably transfected with the h5-HT4(c) receptor, with a pEC50 of 8.3[1].
Velusetrag (100 pM-1 μM) produces concentration-dependent contraction of the guinea pig colonic longitudinal muscle/myenteric plexus (LMMP), with a pEC50 of 7.9[1].
TD-5108 (0.001-10 μM) produces a concentration-dependent relaxation of the carbachol (3 μM)-precontracted rat esophagus, with a pEC50 of 7.9[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Velusetrag (3 mg/kg; a single i.p.) increase hippocampal cAMP levels in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated mice[3].
Velusetrag (0.003-3 mg/kg; a single s.c.) increases colonic transit in a dose-dependent manner and reduces the time taken for excretion of the dye in guinea pigs[2].
Velusetrag (0.003-1 mg/kg; a single i.v.) dose-dependently increases inter-crystal distance, consistent with relaxation of the oesophagus in rats[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 5.5 mg/mL (10.16 mM); Clear solution
This protocol yields a clear solution of ≥ 5.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (55.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 5.5 mg/mL (10.16 mM); Clear solution
This protocol yields a clear solution of ≥ 5.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (55.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
