In vitro | Clamikalant sodium is a selective sarcosine K (ATP) channel inhibitor. It blocks the sK (ATP) current (IC (50) =0.36 mM) induced by the K (ATP) opener pinacidil. [1] In mouse atrial myocytes, both spontaneous activation and diazine-activated K (ATP) currents were effectively inhibited by 10 μM Clamikalant sodium. In contrast, in ventricular myocytes, high concentrations of Clamikalant sodium (100 μM) inhibited the K (ATP) current activated by the pinate, but low concentrations (10 μM) did not. Consistent with this finding, in COSm6 cells, Clamikalant sodium inhibits (86) Rb (+) efflux through Kir6.2/SUR1 more effectively than the Kir6.2/SUR2A channel. [2] |
In vivo | Clamikalant sodium treatment (3 mg/kg push followed by continuous intravenous injection at 17 μg/kg/min throughout the study) did not prevent the shortening of HRA-ERP and the flattening or inversion of ERP rate adaptation in dogs. [3] |
