YM-244769 hydrochloride is a potent, selective and orally active Na+/Ca2+ exchanger (NCX) inhibitor. YM-244769 hydrochloride preferentially inhibits NCX3 and suppresses the unidirectional outward NCX current (Ca2+ entry mode), with IC50s of 18 nM and 50 nM, respectively. YM-244769 hydrochloride efficiently protects against hypoxia/reoxygenation-induced SH-SY5Y neuronal cell damage. YM-244769 hydrochloride can also increase urine volume and urinary excretion of electrolytes in mice[1][2][3].

Target	IC50: 18 nM (NCX3)[1]
In Vitro	YM-244769 (0.003-1 μM) inhibits dose dependently the initial rates of 45Ca2+ uptake into NCX1, NCX2, and NCX3 transfectants with IC50 values of 68 ± 2.9, 96 ± 3.5, and 18 ± 1.0 nM, respectively[1]. YM-244769 (0.3 or 1 μM) efficiently protects against the hypoxia/reoxygenation-induced lactate dehydrogenase (LDH) release in SH-SY5Y cells and in LLC-PK1 cells (1 μM)[1]. YM-244769 possesses reverse mode-selectivity[1]. YM-244769 (1 and 10 μM) inhibits NCX current (INCX) in a concentration- and [Na+]i-dependent manner, the IC50 against the unidirectional outward INCX (Ca2+ entry mode) is 0.05 μM. The IC50 values against the bidirectional outward and inward INCX are similar and approximately 100 nM with a Hill coefficient of about 1[3]. YM-244769 is trypsin-insensitive[3].
In Vivo	YM-244769 (0.1-1 mg/kg; p.o.; once) exhibits dose-dependently natriuretic action in mice and significantly increased urinary excretion of Ca2+ as well as Ca2+/Cr ratio[2]. Animal Model: Wild-type C57BL/6J mice and NCX-KO mice[2] Dosage: 0.1, 0.3 and 1 mg/kg Administration: Oral administration, once Result: Caused a dose-dependent increase (up to approximately 200%) in urine volume and urinary excretion of electrolytes (Na+, K+ and Cl-). Natriuretic actions were equivalently observed in NCX1-KO and WT, but disappeared in NCX2-KO and double KO.
