Adrenergic receptor blockers

Stephanine
Catalog No: CFN98828

l-Stephanine is a potent and highly selective alpha 1 adrenoceptor blocker, inhibits anococcygeus muscle contraction induced by phenylephrine with pA2 values of 6.76. Stephanine shows significant antiplasmodial activities with IC(50) ranged from 1.2 uM to 52.3 uM. Stephanine and crebanine have high inhibitory activity against gram-positive animal pathogenic bacteria, with MIC values of 0.078-0.312g/l, but low inhibitory activity against gram-negative animal pathogenic bacteria, they also inhibit hyphal growth of the plant pathogens Cercospora kaki.
beta-Yohimbine
Catalog No: CFN98921

Beta-Yohimbine has approximately twice as toxic as yohimbine and corynanthine about one fifth as toxic. Beta-yohimbine has alpha-1 and alpha-2 adrenoceptor blocking activities, it has cardiovascular effects. Beta-Yohimbine has anti-plasmodial and anti-malarial activity.
Anisodine
Catalog No: CFN00148

Anisodine is a traditional anticholinergics, it and anisodamine possess alpha 1-adrenoceptor blocking properties, they are widely used in the People's Republic of China for the management of acute circulatory shock . Anisodine can protect optic nerve of primary open angle glaucoma (POAG) through improving the visual function and blood supply of optic nerve. The combination of Anisodine and citicoline with standard steroid and mannitol therapy appears to be effective in the treatment of early optic nerve contusion.
Quinine HCl
Catalog No: CFN90116

Quinine HCl produces alpha-adrenergic blockade. Quinine modifies catecholamine- and calcium-induced myocardial contractile force responses.
