General description

CGP-37157 is a benzothiazepine compound, which is derived from clonazepam. It functions as a sarco/endoplasmic reticulum Ca2+ ATPase (SERCA) antagonist and ryanodine receptor channels (RyR) agonist. CGP-37157 regulates intracellular signaling of calcium in smooth, cardiac and skeletal muscle cells and non-muscle systems.

Application

CGP-37157 has been used as a mitochondrial sodium-calcium exchanger (mNCX) inhibitor to study the role of normal mitochondrial calcium dynamics in sustaining dendritic spinogenesis.

Biochem/physiol Actions

Specific inhibitor of mitochondrial Na+/Ca2+ exchange as well as sarcoplasmic reticulum calcium-stimulated ATPase and possibly other calcium channels.

We studied how mitochondrial Ca2+ transport influences [Ca2+](i) dynamics in sympathetic neurons. Cells were treated with thapsigargin to inhibit Ca2+ accumulation by SERCA pumps and depolarized to elevate [Ca2+(i); the recovery that followed repolarization was then examined. The total Ca2+

7-Chloro-5-(2-chlorophenyl)-1,5-dihydro-4,1-benzothiazepin-2(3H)-one [CGP-37157 (CGP)], a benzothiazepine derivative of clonazepam, is commonly used as a blocker of the mitochondrial Na+/Ca²+ exchanger. However, evidence suggests that CGP could also affect other targets, such as L-type Ca²+ channels and plasmalemma Na+/Ca²+ exchanger. Here, we

Many models have been developed to account for stimulus-evoked [Ca(2+)] responses, but few address how responses elicited in specific cell types are defined by the Ca(2+) transport and buffering systems that operate in the same cells. In this study, we
