2-[2-[4-(4-NITROBENZYLOXY)PHENYL]ETHYL]ISOTHIOUREA MESYLATE Chemical Properties,Usage,Production

Description

KB-R7943 (182004-65-5) is a potent and selective inhibitor of the reversed Na+/Ca2+ exchanger (NCE or NCX; IC50‘s = 1.2-2.4 μM in cardiomyocytes, smooth muscle cells, NCX1-transfected fibroblasts1; 0.7 μM in cultured rat forebrain2). KB-R7943 has also been shown to inhibit the mitochondrial Ca2+ uniporter (MCU) Ki = 5.5 μM.3 Recently shown to inhibit complex I in the mitochondrial respiratory chain (IC50 = 11.4 μM) and block NMDA receptors (IC50 = 13.4 μM).4

Uses

KB-R7943 Mesylate is a selective inhibitor of the reverse mode of Na+/Ca2+ exchange in cells expressing NCX1.

General Description

A cell-permeable inhibitor of the influx/reverse mode of the Na+/Ca2+ exchanger (NCX) (IC50 = 4.3 μM for NCX1, 4.7 μM for NCX2, and 1.4 μM for NCX3). Directly modulates Na+/Mg2+ exchange in a Ca2+-dependent manner. Reported ot offer neuronal and cardio-protection against ischemic injury. Also inhibits nicotinic acetylcholine receptors and NMDA receptor channels (IC50<10 μM).

Biological Activity

Potent, selective inhibitor of the reverse mode of the Na + /Ca 2+ exchanger (IC 50 = 0.7 mM). Does not affect Na + -dependent transport systems, Na + channels or ionotropic glutamate receptors.

Biochem/physiol Actions

Target IC50: 4.3 μM, 4.7 μM, and 1.4 μM for NCX1,NCX2, and NCX3, respectively

storage

Room temperature
