| Description | SKA-31 (40172-65-4) is a KCa3.1 and KCa2 potassium channel activator (EC50 =260, 2900, 2900 nM for KCa3.1, KCa2.1 and KCa2.2 respectively). Enhanced acetylcholine-induced EDHF dilator response in mouse carotid arteries and lowers blood pressure in mouse models at 30 mg/Kg.1,2 Evokes robust vasodilation in rat mesenteric arteries.3 | | Uses | SKA-31 is a potent potassium channel activator with EC50s of 260 nM, 1.9 μM, 2.9 μM, and 2.9 μM for KCa3.1, KCa2.2, KCa2.1 and KCa2.3, respectively. SKA-31 potentiates endothelium-derived hyperpolarizing factor response and lowers blood pressure[1]. | | Biological Activity | Activator of K Ca 3.1 and K Ca 2 channels (EC 50 values are 260, 2900, 2900 nM for K Ca 3.1, K Ca 2.1 and K Ca 2.2 respectively). Potentiates acetylcholine-induced EDHF-type dilations of mouse carotid arteries and lowers blood pressure in normotensive and hypertensive mice. | | in vivo | SKA-31 is not acutely toxic and has good pharmacokinetic properties[1].
SKA-31 potentiates native KCa3.1 and KCa2.3 in murine carotid endothelium with EC50 values of 225 nM and 1.6 μM for KCa3.1 and KCa2.3, respectively[1].
SKA-31 stimulates KCa3.1 and KCa2.3 in vascular endothelial cells and increases acetylcholine-induced endothelium-derived hyperpolarizing factor (EDHF) -mediated vasodilation[1].
SKA-31 potentiates EDHF-type vasodilations and lowers blood pressure in mice. Injections of SKA-31 (1-30 mg/kg; i.p.) lower MAP over 24 hours in normotensive wild-type mice but not in KCa3.1(-/-) mice (-/-)[1].
| Animal Model: | 16-25 weeks mice[1] | | Dosage: | 1 mg/kg, 10 mg/kg, and 30 mg/kg | | Administration: | Intraperitoneal injection | | Result: | Lower MAP over 24 hours in normotensive wild-type mice but not in KCa3.1(-/-) mice (-/-). |
