VU0255035 (0.1-3 μM) parallels the rightward shift of the concentration-response relationship of acetylcholine (ACh)-induced calcium mobilization and interacts with the orthosteric binding site of ACh as a competitive antagonist[1].
VU0255035 (1 nM-0.1 μM; 75 min) concentration-dependently blocks carbachol (CCh)-induced phosphatidylinositol (PI) hydrolysis in rat hippocampal slices with an IC50 of 2.4 μM[1].
VU0255035 (5 μM) completely blocks CCh-induced enhancement of NMDAR currents in hippocampal CA1 pyramidal neurons[1].
VU0255035 (5 μM) can significantly reduce the amplitude of choline-induced long-term depression (LTD) in hippocampal slice electrophysiological experiments, proving that choline-induced LTD depends on M receptors[2].
VU0255035 (5 μM) can completely block CCh-induced membrane potential depolarization of pyramidal neurons in the medial prefrontal cortex (mPFC) in brain slice membrane potential recording experiments[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
VU0255035 (3-30 mg/kg; ip; single dose) has no effect on the acquisition of contextual fear conditioning in a rat contextual fear conditioning model, similar to M1 mAChR knockout mice. VU0255035 may not cause severe cognitive deficits like non-selective anticholinergic drugs[1].

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 (4.81 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 (4.81 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
