Manidipine dihydrochloride

Manidipine dihydrochloride (CV-4093) is a hydrochloride salt of manidipine that is a lipophilic, third-generation, highly vasoselective dihydropyridine calcium antagonist with an IC50 of 2.6 nM. Manidipine dihydrochloride (CV-4093) causes systemic vasodilation by inhibiting the voltage-dependent calcium inward currents in smooth muscle cells. Manidipine dihydrochloride (CV-4093) is used clinically as an antihypertensive. Manidipine dihydrochloride (CV-4093) suppressed the DNA synthesis of vascular smooth muscle cells (VSMC) dose dependently at concentrations of more than 10 nM. Mandipine hydrochloride (1 uM) suppressed proliferation of VSMC to 50% of the control value. Manidipine hydrochloride stimulated the synthesis of GAG at concentrations above 0.01 nM. Manidipine hydrochloride (10 nM) stimulated synthesis of glycosaminoglycans (GAG) to 450% of control.
