 Use of Manidipine hydrochloride


Manidipine 2Hcl (CV-4093) is a dihydropyridine compound and a calcium channel blocker for Ca2+ current with IC50 of 2.6 nM. IC50 value: 2.6 nMTarget: calcium channelManidipine is described to block T-type Ca2+ channels specifically and is also described to have a high selectivity for the vasculature, presenting negligible cardiodepression as compared to other Ca2+ channel antagonists. Manidipine is also described to not significantly affect norepinephrine levels, suggesting a lack of sympathetic activation with this compound. Manidipine reduces pro-inflammatory cytokines secretion in human endothelial cells and macrophages. Manidipine, unlike other third-generation dihydropyridine derived drugs, blocks T-type calcium channels present in the efferent glomerular arterioles, reducing intraglomerular pressure and microalbuminuria.
