Barnidipine hydrochloride

Описание

Barnidipine hydrochloride, chemically known as (3S)-1-benzyl-3-pyrrolidinylmethyl-(4S)-2,6-dimethyl-4-(m-nitrophenyl)-1,4-dihydropyridine-3,5-dicarboxylate hydrochloride, is a new long-acting dihydropyridine calcium antagonist developed and marketed by Yamanouchi Pharmaceutical (now Astellas Pharma). This medication effectively lowers blood pressure without impacting heart rate by specifically targeting calcium channels responsible for transmembrane potential. By inhibiting calcium influx into cells, it selectively relaxes smooth muscle in peripheral and coronary blood vessels.

Химические свойства

Pale Yellow Solid. Melting point 226-228°C. [α]D20+116.4° (C=1, methanol). Insoluble in water. Acute toxicity LD50 male and female rats (mg/kg): 105, 113 Oral.

Использование

Barnidipine hydrochloride is a vasodilating dihydropyridine calcium antagonist useful in the treatment of primary hypertension and renal hypertension. In experimental animals, its hypotensive effect was more potent and longer acting than nicardipine, nifedipine and nitrendipine.

Определение

ChEBI: Barnidipine hydrochloride is a dihydropyridine. 1,4-Dihydropyridine calcium antagonist with antihypertensive and diuretic effects. It is a potential candidate in the treatment of patients with renal parenchymal hypertension.

Биологическая активность

Barnidipine is a dihydropyridine calcium channel blocker that has an IC50 value of 0.35 nM in potassium-induced tonic contraction of pig coronary artery. It demonstrates antihypertensive activity by reducing peripheral vascular resistance. It decreases blood pressure in spontaneously hypertensive rats when administered orally at 1 and 3 mg/kg per day. Formulations containing barnidipine have been used as a treatment for hypertension.
