説明Quinidine sulfate dihydrate is a diastereomer of quinine and a Na+ channel blocker. Also a class I antiarrhythmic drug. Quinidine sulfate dihydrate is a white, odorless crystalline substance that has a bitter flavor. It has limited solubility in water and alcohol but dissolves easily in chloroform and ether. This compound is effective against bacteria resistant to erythromycin, including staphylococci and streptococci, and works by inhibiting cellular ATPases.

使用Quinidine sulfate dihydrate (cas# 6591-63-5) is the hydrated, sulfate salt of Quinidine (Q685000), a dextrorotatory stereoisomer of Quinine. Antiarrhythmic (class IA). Antimalarial.

一般的な説明Quinidine sulfate dihydrate is the sulfateof an alkaloid obtained from various species ofCinchona and their hybrids. It is a dextrorotatory diastereoisomerof quinine. The salt crystallizes from wateras the dihydrate, in the form of fine, needlelike, white crystals.Quinidine sulfate contains a hydroxymethyl groupthat serves as a link between a quinoline ring and a quinuclidinemoiety. The structure contains two basic nitrogens,of which the quinuclidine nitrogen is the stronger base(pKa 10). Quinidine sulfate dihydrate is bitter and light sensitive.Quinidine sulfate dihydrates are nearly neutral or slightly alkaline. Itis soluble to the extent of 1% in water and more highly solublein alcohol or chloroform.
