解説ウアバイン.キョウチクトウ科Strophanthus gratusやAcokanthera ouabaioの種子中に存在する強心配糖体.加水分解により1 mol のウアバゲニンと1 mol のL-ラムノースを与える.板状晶(八水和物).融点190 ℃(分解).[α]25D-31°(メタノール).光で分解する.水,エタノールに難溶.LD50 17.2 mg/kg(ネズミ,静注).
説明One of several cardiac glycosides that have been used clinically as cardiotonic agents and diuretics. Ouabain is obtained from the seeds of Strophanthus gratus, Acokanthera ouabaio, and related species. It was formerly prescribed under the name strophanthuis as the purified seed extract.
一般的な説明Odorless, white crystals or crystalline powder as an octahydrate. Used to produce rapid digitalization in acute congestive heart failure. Also recommended in treatment of atrial or nodal paroxysmal tachycardia and atrial flutter.
純化方法It crystallises from water as the octahydrate. Dry it at 130o. It decomposes at 190o when dry. Store it in the dark as it is light sensitive, but it is stable in air. Its solubility (g/100mL) in H2O is 1.3 (~25o), 20 (~100o), and in EtOH it is 1.0 (~25o) and 12.5 (~78o). It is highly TOXIC as it is an inhibitor of cation transport and of Na+ and K+ ATPase.
