描述 | YM-244769 is a potent, selective, and orally active inhibitor of the Na+/Ca2+ exchanger (NCX). It preferentially targets NCX3 and inhibits the unidirectional outward NCX current (Ca2+ entry mode) with IC50 values of 18 nM and 50 nM, respectively. YM-244769 effectively guards against hypoxia/reoxygenation-induced damage in SH-SY5Y neuronal cells. Additionally, it increases urine volume and the urinary excretion of electrolytes in mice [1][2][3]. |
体外研究 | YM-244769 (1 and 10 μM) suppresses the NCX current (INCX) in a manner dependent on both concentration and intracellular sodium concentration. The IC50 for unidirectional outward INCX (Ca2+ entry mode) is 0.05 μM. The IC50 values for bidirectional outward and inward INCX are comparable, approximately 100 nM[3]. |
