Summary
YM-244769 hydrochloride is a potent, selective and orally active Na + /Ca 2+ exchanger ( NCX ) inhibitor. YM-244769 hydrochloride preferentially inhibits NCX3 and suppresses the unidirectional outward NCX current (Ca 2+ entry mode), with IC 50 s 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] .
IC50 & Target

In Vitro
YM-244769 (0.003-1 μM) inhibits dose dependently the initial rates of

values of 68 ± 2.9, 96 ± 3.5, and 18 ± 1.0 nM, respectively

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
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 Ca 2+ as well as Ca 2+ /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. |
