Preclinically, aclidinium showed potent antagonism of human muscarinic receptors, with a long residence time at M3 receptors and a shorter residence time at M2 receptors, indicating the potential to provide sustained bronchodilation. Aclidinium is rapidly hydrolysed in human plasma, unlike other currently available antimuscarinics including tiotropium. Early clinical studies in healthy subjects have confirmed the low systemic bioavailability and favourable safety profile of single and multiple doses of aclidinium. In a subsequent Phase IIb study, which included 464 patients with moderate to severe COPD, aclidinium displayed long-lasting bronchodilatory activity and was well tolerated.

Aclidinium Bromide purchased from MedChemExpress. Usage Cited in: Oncol Lett. 2018 Nov;16(5):6417-6422. [Abstract]
Western blotting is used to examine the proteins closely related with apoptosis. Results reveal that after treatment with Aclidinium, the expression of the anti-apoptotic protein, Bcl-2, is decreased while the level of pro-apoptotic protein Bax and active-caspase-3 are increased significantly.

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 (4.43 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 (4.43 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.
