Biological Activity
IC50：2.9 μM (NCX1), 16 μM (NCX2), 8.6 μM (NCX3)[1]
SN 6 is a selective Na+/Ca2+ exchanger inhibitor, which inhibits the initial rate of 45Ca2+ uptake into NCX1, NCX2, and NCX3 transfectants with IC50 values of 2.9 ± 0.12, 16 ± 1.1, and 8.6 ± 0.27 μM. SN 6 (up to 30 μM) also less potently inhibits muscarinic acetylcholine receptor, with a higher IC50 of 18 μM. SN 6 (0.3-30 μM) completely inhibits the initial rate of Na+i-dependent 45Ca2+ uptake into Na+-loaded sarcolemmal vesicles in a dose dependent manner (IC50, 5.3 ± 0.37 μM). SN 6 (0.3-10 μM) dose-dependently protects against the hypoxia/reoxygenation-induced LDH release in parental LLC-PK1 cells and NCX1 transfectants but not in K229Q transfectants[1]. SN 6 (1-30 μM) suppresses the bidirectional outward and inward INCX in a concentration-dependent manner, with IC50 values of 2.3 μM and 1.9 μM, respectively. SN 6 also inhibits bidirectional current (INCX) in a [Na+]i concentration-dependent manner, with IC50 values of 3.4 μM, 2.3 μM, and 1.1 μM at 10 mM, 20 mM, and 30 mM [Na+]i, respectively[2]. SN 6 inhibits hypoxia/reoxygenation-induced LDH release with an IC50 value of 0.63 ± 0.15 μM in NCX1 transfectants[3].

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: 2.08 mg/mL (5.17 mM); Suspended solution; Need ultrasonic and warming
This protocol yields a suspended solution of 2.08 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol
Na+i-dependent 45Ca2+ uptake into cells expressing the wild-type or mutated exchangers are assayed. In brief, confluent transfectants in 24-well dishes are loaded with Na+ by incubation at 37°C for 40 min in 0.5 mL of balanced salt solution (BSS) (10 mM HEPES/Tris, pH 7.4, 146 mM NaCl, 4 mM KCl, 2 mM MgCl2, 0.1 mM CaCl2, 10 mM glucose, and 0.1% bovine serum albumin) containing 1 mM ouabain and 10 μM monensin. 45Ca2+ uptake is then initiated by switching the medium to Na+-free BSS (replacing NaCl with equimolar choline chloride) or to normal BSS, both of which contain 0.1 mM 45CaCl2 (370 kBq/mL) and 1 mM ouabain. After a 30-s incubation, 45Ca2+ uptake is terminated by washing cells four times with an ice-cold solution containing 10 mM HEPES/Tris, pH 7.4, 120 mM choline chloride, and 10 mM LaCl3. Cells are then solubilized with 0.1 N NaOH, and aliquots are taken for determination of radioactivity and protein. When present, SN 6 and KB-R7943 are included in the medium 15 min before the start of 45Ca2+ uptake[1].
