Description

SN 6 is a selective Na+/Ca2+ exchanger (NCX) inhibitor, and inhibits 45Ca2+ uptake by NCX1, NCX2, and NCX3, with IC50s of 2.9, 16, and 8.6 μM, respectively.

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].

Protocol

Cell experiment:

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].
