CatSper[1]
HC-056456 similarly slows the rise of [Ca2+]i that is evoked by alkaline depolarization and reported by fura-2. HC-056456 also selectively and reversibly decreased CatSper currents recorded from patch-clamped sperm. HC-056456 produces a pharmacological phenocopy of the CatSper-null sperm. Acute application of HC-056456 causes rapid loss of flagellar waveform asymmetry from hyperactivated sperm, indicating that continued entry of Ca2+ through CatSper channels is required to maintain hyperactivation. HC-056456 selectively and reversibly blocks CatSper currents. The specificity and reversibility of the blockade of CatSper-dependent currents by HC-056456 is examined by using patch clamp recordings. The observed current is blocked slightly more than 50% by 20 μM HC-056456 (estimated IC50 near 15 μM). In concept, it remains possible that CatSper channel heterogeneity explains residual HC-056456-resistant current. The action of HC-056456 on KSper channels, the other major cation channel observed in patch-clamped sperm, is also examined. Subsequent application of 50 μM HC-056456 results in partial blockade of this current. For HC-056456 action on KSper an IC50 near 40 μM is estimated[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 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (6.79 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.
