Background
KB-R7943 mesylate is a potent and selective inhibitor of Na+/Ca2+ exchanger (NCE) with IC50 value of 0.7 μM.NCE is an antiporter membrane protein that exchanges 3 Na+ for 1 Ca2+ and can function to cause Ca2+ accumulation (reverse mode) or Ca2+ extrusion (forward mode) depending on the concentrations of each ion on either side of the membrane and on the membrane potential [1].In transfected Chinese hamster ovary (CHO) cells expressing NCE, KB-R7943 (10 μM) inhibited NCX activity at high (140mM) but not at low (10mM) cytosolic Na+ concentrations [2]. In cultured rat forebrain neurons loaded with glutamate- (3 μM), N-methyl-D-aspartate- (30 μM), kainate- (100 μM) or KCl- (50 mM) induced [Ca2+] transients, KBR7943 inhibited these transients with IC50 values of 6.6, 8.2, 5.2 and 2.9 μM, respectively. While, KB-R7943 didn’t inhibit glutamate-induced neuronal injury [1]. In mice with ischemic acute renal failure (ARF), KB-R7943 significantly decreased endothelin-1 (ET-1) in the kidney and relieved the ARF-induced renal dysfunction [3].
