IC50: 0.8 μM (Na⁺/Ca²⁺ exchanger)^[1]

CGP37157 (Compound XVI) is a potent, selective inhibitor of Na⁺/Ca²⁺ exchanger, inhibiting the Na⁺-induced Ca²⁺-release from guinea-pig heart mitochondria, with an IC₅₀ of 0.8 μM^[1]. CGP37157 (10 μM) shows inhibitory effect on mitochondrial Na⁺/Ca²⁺ exchanger in cortical neurons, modulates intracellular Ca²⁺ levels via suppresssing voltage-gated calcium channels, and reduces NMDA-induced cytosolic and mitochondrial Ca²⁺ overloads. CGP37157 (10 μM) also reduces NMDA-induced excitotoxicity, and such an effect is via attenuating mitochondrial damage and calpain activity in neurons^[2]. CGP37157 (10 μM) in combination with salinomycin significantly attenuates cell viability and increases apoptosis of FaDu and HLaC79 cells. Moreover, CGP37157 has no inhibitory effect on salinomycin tumor toxicity^[3].

Cell toxicity assays are performed. Neurons are exposed to NMDA in HBSS (free of Ca²⁺ and Mg²⁺) containing 2.6 mM CaCl₂, 10 mM glucose and 10 μM glycine for 10 or 30 min at 37°C, depending on the experiment. CGP37157 is present before and during the excitotoxic insult and cell viability is assessed 24 h later using Citotox 96 colorimetric assay. All experiments are performed in quadruplicate and the values provided are the normalized mean ± S.E.M. of at least three independent experiments^[1].
