Methyl 2-(2,3-Dichlorobenzylidine)acetoacetate (CAS: 74073-22-6), intermediate of Felodipine (CAS: 72509-76-3; 86189-69-7). Felodipine is a vasodilatory calcium antagonist with a high degree of vascular selectivity. Felodipine is currently indicated for use only in hypertension, either as monotherapy or in conjunction with diuretics or beta blockers Felodipine is a 1,4-dihydropyridine small molecule antagonist and calcium channel protein inhibitor. Antagonism of the vascular L-type (long-lasting) calcium channel decreases intracellular calcium concentration, softening the tone of vascular tissue and decreasing the peripheral resistance upon the blood stream, effectively decreasing systemic arterial blood pressure without affecting myocardial contractility. Felodipine is described to inhibit cytokine-induced NO and superoxide production as well as cytokine-induced NO synthase (NOS) mRNA induction, and is suggested to act as a scavenger of superoxide and not an inhibitor of inducible NOS induction. This indicates that Felodipine further protects the vasculature against endogenous free radical generation during inflammatory responses.
