Summary
YM-244769 dihydrochloride is a potent, selective and orally active Na + /Ca 2+ exchanger ( NCX ) inhibitor. YM-244769 dihydrochloride 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 dihydrochloride efficiently protects against hypoxia/reoxygenation-induced SH-SY5Y neuronal cell damage. YM-244769 dihydrochloride can also increase urine volume and urinary excretion of electrolytes in mice [1] [2] [3] .

Cell Viability Assay [1]
| Cell Line: | SH-SY5Y cells treated with NCX1 or NCX3 antisense |
| Concentration: | 0.3 and 1 μM |
| Incubation Time: | |
| Result: |
Hypoxia/reoxygenation-induced LDH release was significantly attenuated: reduction in cell damage was greater in cells treated with NCX3 antisense (by 61%) than in cells treated with NCX1 antisense (by 35%).
0.3 or 1 μM efficiently suppressed the hypoxia/reoxygenation-induced cell damage in SH-SY5Y cells treated with NCX1 antisense more than in those treated with NCX3 antisense. |
In Vivo
YM-244769 (0.1-1 mg/kg; p.o.; once) exhibits dose-dependently natriuretic action in mice and significantly increases urinary excretion of Ca 2+ as well as Ca 2+ /Cr ratio [2] .
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
| 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. |
