Nilvadipine Usage And Synthesis
Description
Nilvadipine is a new, second-generation calcium channel blocker effective in the treatment of hypertension and angina pectoris. Its potent inhibitory effect on the stimulated chemotaxis of smooth muscle cells and protective action against calcium deposition suggest that nilvadipine may be useful for preventing and treating atherosclerosis.
Chemical Properties
Yellow Prisms
Originator
Fujisawa (Japan)
Uses
Used as an antihypertensive and antianginal.
Uses
antihypertensive;calcium channel blocker
Definition
ChEBI: Nilvadipine is an isopropyl ester, a methyl ester, a nitrile and a dihydropyridine.
Manufacturing Process
To a solution of isopropyl ester of 6-formyl-5-methoxycarbonyl-2-methyl-4-(3- nitrophenyl)-1,4-dihydropyridine- 3-carboxylic acid (4.5 g) in acetic acid (35 ml) were added hydroxylamine hydrochloride (0.97 g) and sodium acetate (1.43 g), and the mixture was stirred at ambient temperature for 2.5 hours. After acetic anhydride (4.14 g) was added to this reaction mixture, the mixture was stirred at ambient temperature for 1.5 hours and at 95-100°C for additional 4 hours. The acetic acid and the excess of acetic anhydride were removed in vacuum, followed by adding water to the residue and it was neutralized with a saturated aqueous solution of sodium bicarbonate. This aqueous suspension was extracted twice with ethyl acetate, and the combined extract was washed with water, dried over anhydrous magnesium sulfate and evaporated to dryness under reduced pressure to give a reddish-brown oil (4.88 g), which was chromatographed over silica gel (150 g) with a mixture of benzene and ethyl acetate (10:1 by volume) as an eluent to give a crude crystals (2.99 g). These were recrystallized from ethanol to give yellow prisms (1.89 g) of isopropyl ester of 6-cyano-5-methoxycarbonyl-2-methyl-4-(3- nitrophenyl)-1,4-dihydropyridine-3-carboxylic acid melting point 148-150°C (yellow prisms from ethanol); [α]D20 = 222.4° (c = 1 in methanol).
