| AROTINOLOL HCL Usage And Synthesis |
| Description | Arotinolol hydrochloride i s a β-adrenergic
blocker with weak
α-antagonistic properties,
useful in the treatment of hypertension. | | Originator | Sumitomo (Japan) | | Uses | Arotinolol is both and alpha- and beta-adrenoceptor antagonist and is used to treat essential tremors and hypertension. | | Manufacturing Process | To a solution of 2-mercapto-4-(5'-carbamoyl-2'-thiophenyl)thiazole, 3.2 g in
20 ml of 0.3 % aqueous sodium hydroxide solution, 1-chloro-3-tbutylaminopropanol,
12.64 g in 20 ml of methanol was added, while the
temperature was maintained at 20°C.
The reaction solution was stirred at room temperature for 4 h, and then
condensed to a half volume in vacuo. The residual solution, added with 100 ml
of water, was extracted with chloroform. The chloroform extract was washed
with water, dried over anhydrous magnesium sulfate and evaporated in vacuo
to give 4.8 g of 2-(3'-t-butylamino-2'-hydroxypropylthio)-4-(5'-carbamoyl-2'-
thiophenyl)thiazole, as crystals, melting point 234°-235.5°C (dec.,
recrystallized from methanol/water).
In practice it is usually used as hydrochloride. | | Brand name | ALMARL | | Therapeutic Function | Beta-adrenergic blocker |
