Cinanserin hydrochloride
Based on 1 publication(s) in Google Scholar
Cinanserin hydrochloride (SQ 10643) is a potent, selective and highly affinity 5-HT2 receptor antagonist with a Ki of 41 nM. Cinanserin hydrochloride has a much higher binding affinity for the 5-HT2 than for the 5-HT1 receptor (Ki of 3500 nM). Cinanserin is also an inhibitor of 3C-like proteinase of severe acute respiratory syndrome coronavirus and strongly reduces virus replication in vitro.

Cinanserin/Cinanserin hydrochloride have binding affinity to SARS-CoV 3CLpro, HCoV-229E 3CLpro, with the KD values of 49.4 μM/78.0 μM for SARS-associated coronavirus (SARS-CoV) 3CLpro and 18.2 μM/36.6 μM for human coronavirus 229E (HCoV-229E) 3CLpro[1].
The IC50 values of Cinanserin and Cinanserin hydrochloride for inhibiting the catalytic activity of SARS-CoV 3CLpro are calculated as 4.92 μM and 5.05 μM, respectively, The corresponding IC50 values for HCoV-229E 3CLpro are 4.68 μM and 5.68 μM. None of the compounds have inhibitory activity against HRV-14 3Cpro at concentrations up to 200 μM[1].

Solvent & Solubility
DMSO : 125 mg/mL (331.62 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 100 mg/mL (265.29 mM; Need ultrasonic)
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, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

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 (5.52 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 (5.52 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.
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.
