Barnidipine C화학적 특성, 용도, 생산
개요
Barnidipine is a long-acting novel calcium antagonist that belongs to the dihydropyridine (DHP) group of calcium channel blockers. It contains two chiral centres thus can have four possible enantiomers. The active component is composed of a single optical isomer (3'S, 4S configuration), which is the most potent and longest-acting of the four enantiomers. Barnidipine has shown to be an effective antihypertensive agent in the management of hypertension in elderly patients and its efficacy is not negatively affected by age.Originator
Barnidipine,YamanouchiManufacturing Process
In 5 ml of isopropyl alcohol were dissolved 1.5 g (0.01 mole) of 3- nitrobenzaldehyde, 2.6 g (0.01 mole) of 1-benzyl-3-acetoacetyloxypyrrolidine, and 1.3 g (0.01 mole) of β-aminocrotonic acid methyl ester and then the solution was refluxed for 8 hours. The solvent was distilled off under reduced pressure, the residue obtained was dissolved in a small amount of chloroform, and the solution was applied to silica gel column chromatography (column diameter 1.5 cm, height 20 cm, and about 200 ml of chloroform was used as the eluent). The eluates were collected and concentrated to give 3.4 g of oily 2,6-dimethyl-4-(3'-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylic acid-3- (1-benzylpyrrolidin-3-yl)ester-5-methyl ester: [α]D 20=+64.8° (c = 1 in methanol).Therapeutic Function
Coronary vasodilator부작용
The side effects of barnidipine are typically mild to moderate and typically occur at the beginning of treatment. Common side effects include nausea, palpitations, flushed face, hot flashes, swelling, headache, heavy sensation in the head, dizziness, and a feeling of unsteadiness. Other reported side effects include redness, rash, itching, and sensitivity to sunlight.참고 문헌
