|Biological target:||HC-056456 is a blocker of CatSper channels.|
|In vitro activity:||N/A|
|In vivo activity:||The CatSper channel is the predominant route for evoked Ca2+ entry into intact mouse sperm. Compound HC-056456 was identified as a potential inhibitor of CatSper in a chemical-library screenThe efficacy of HC-056456 to inhibit evoked Ca2+ entry was examined. In Figs. 3A–C, fura-2 reported the spatially-averaged [Ca2+]i of sperm during challenge with a paired-stimulus protocol. Medium K8.6 evoked averaged rates of rise of 8.7 and 6.6 nM Δ[Ca2+]i s−1 during the first and second stimuli when no inhibitor was present. When 3 µM HC-056456 was applied after the first stimulus, the averaged rate decreased from ∼7.5 to ∼1.6 nM Δ[Ca2+]i s−1. When 10 µM HC-056456 was applied after the first stimulus, the averaged rate decreased more strongly, from ∼7.0 to ∼0.7 nM Δ[Ca2+]i s−1. Hence HC-056456 is an effective inhibitor of the CatSper Ca2+ channel activity that is evoked by alkaline depolarization. Fig. 3D shows that at 10 µM the HC-056456 also strongly decreased the rise in [Na+]i that was evoked by removal of external Ca2+. The rates of rise before and during exposure to HC-056456 were ∼0.03 and ∼0.01 ΔRSBFI min−1. Reference: PLoS One. 2009; 4(8): e6844. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2729922/|
