Biochem/physiol Actions DCPIB is a potent inhibitor of the volume-sensitive anion channel (VSAC). IC50 = 4.1μM ) versus ICl,swell in calf pulmonary artery endothelial (CPAE) cells. DCPIB does not inhibit CPAE cell ICl,Ca; hCFTR; nor guinea pig ICl,PKA, IKr, IKs,IKl, INa and ICa. DCPIB inhibition is reversible and voltage independent. ICl,swell is believed to be important in cardiovascular function. Studies have been limited by the lack of specific ligands. |
