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

Biological Activity
IC50: 18 nM (NCX3), 68 nM (NCX1), 96 nM (NCX2)[1]
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].

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.

-
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.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
