Background:

SKF 96365 hydrochloride is an inhibitor of store-operated calcium entry (SOCE). Also, it inhibits transient receptor potential cation channels (TRPCs) and voltage-gated sodium current [1] [2] [3].

Store-operated calcium entry (SOCE) increases cytosolic Ca2+ and induces the entry of extracellular calcium. TRPC channels are divided into store-operated and receptor-operated channels and play a critical role in brain development [1] [2].

SKF 96365 hydrochloride is a SOCE inhibitor. In MPP+ stressed PC12 cells, SKF-96365 (10, 50 μM) significantly prevented nuclear damage, decreased LDH release, increased cell viability and inhibited apoptosis. Also, SKF-96365 inhibited Homer1-mediated endoplasmic reticulum (ER) Ca2+ release and intracellular calcium overload induced by MPP+ injury [1]. In rat ventricular myocytes, SKF-96365 inhibited INa in a frequency-dependent and use-dependent way [3]. In Madin Darby canine kidney (MDCK) cells, SKF 96365 (25-100 μM) induced a robust [Ca2+]i transient in a dose-dependent way [4].

In rats, SKF-96365 significantly inhibited persistent spontaneous nociception induced by melittin and reduced hypersensitivity to both mechanical and thermal stimuli. These results suggested that SKF-96365-sensitive TRPC channels were involved in the processing of melittin-induced hypersensitivity and inflammatory pain [2].
