PCS1055 dihydrochloride
Based on 2 publication(s) in Google Scholar
PCS1055 dihydrochloride is a potent, selective and competitive muscarinic M4 receptor antagonist with an IC50 of 18.1 nM and a Kd of 5.72 nM. PCS1055 dihydrochloride inhibits radioligand [3H]-NMS binding to the M4 receptor with a Ki of 6.5 nM. PCS1055 dihydrochloride exhibits >100-fold selectivity over M1-, M3-, and M5-receptors and 30-fold selectivity at the M2 receptor. PCS1055 dihydrochloride is also a potent AChE inhibitor with IC50 s of 22 nM and 120 nM for electric eel and human AChE, respectively.

PCS1055 also antagonized functional signal transduction as demonstrates by the inhibition of agonist-stimulated GTP-γ-[35S] binding. PCS1055 inhibits G protein activation in a concentration dependent manner, with the highest potency at the M4 receptors. Both studies shows that PCS1055 is most potent at the M4 receptor subtype with a binding preference of 130-, 31.2-, 426- and >1000-fold, and functional preference of 255-, 69.1-, 342- and >1000-fold over the M1-, M2-, M3- and M5 receptors, respectively[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: ≥ 2.5 mg/mL (5.15 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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: ≥ 2.5 mg/mL (5.15 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
