Imidafenacin
Based on 1 Customer Validation
Imidafenacin (KRP-197; ONO-8025) is an orally active inhibitor of muscarinic (mAChR) M1 and M3 receptors. Imidafenacin potently inhibits bladder contraction in vivo and exerts an antidiuretic effect by enhancing the signaling pathway of vasopressin (antidiuretic hormone). Imidafenacin can be used in research related to overactive bladder.

Imidafenacin (0.05-0.2 mg/kg; p.o.; single dose) dose-dependently prevents carbamylcholine-induced reductions in bladder capacity in conscious female rats with an ID50 of 0.055 mg/kg, and significantly lowers maximum intravesical pressure at doses of 0.05, 0.1, and 0.2 mg/kg[2].
Imidafenacin (0.0625-1 mg/kg; p.o.; singe dose) dose-dependently inhibits distention-induced rhythmic bladder contractions in conscious male rats with an ID30 of 0.17 mg/kg, with effects peaking 30-50 minutes post-dosing and lasting at least 120 minutes[2].
Imidafenacin (0.3-2.4 mg/kg; p.o.; single dose) dose-dependently inhibits carbamylcholine-induced salivary secretion in conscious male rats with an ID50 of 1.5 mg/kg[2].
Imidafenacin (1-10 mg/kg; p.o.; daily; 7 days) does not impair spatial learning or memory in male rats tested in the Morris water maze task[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Sprague-Dawley (female, 220-290 g, orally water-loaded)[1]
-
Dosage:3-300 μg/kg
-
Administration:i.v.; single dose
-
Result:Dose-dependently suppressed urine production, with the minimum effective dose identified as 10 μg/kg.
Produced approximately 50% inhibition of urine volume relative to the vehicle group at 100 μg/kg.
Enhanced the antidiuretic effect beyond that of either agent alone when administered at 10 μg/kg in combination with desmopressin at its minimum effective dose.
Had its antidiuretic effect completely inhibited by pretreatment with 3 mg/kg mozavaptan at 10 μg/kg and 300 μg/kg.
Further suppressed urine production compared to desmopressin alone in the presence of mozavaptan when 300 μg/kg was added to a combination of 3 mg/kg mozavaptan and 0.1 μg/kg desmopressin.
-
Animal Model:Wistar rats (male, 190-340 g)[2]
-
Dosage:1 mg/kg; 10 mg/kg
-
Administration:p.o.; daily; 7 days
-
Result:Did not alter escape latencies during the acquisition phase compared to vehicle controls at doses of 1 mg/kg and 10 mg/kg.
Showed a significant preference for the quadrant where the platform was previously placed during the spatial probe trial at doses of 1 mg/kg and 10 mg/kg, similar to vehicle controls.

Solvent & Solubility
DMSO : 31.25 mg/mL (97.84 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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: ≥ 2.08 mg/mL (6.51 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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: ≥ 2.08 mg/mL (6.51 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
