desomorphine
Desomorphine (dihydrodesoxymorphine, former brand name Permonid, street name krokodil) is a derivative of morphine with powerful, fast-acting opioid effects, such as sedation and analgesia. First synthesized in 1932 and patented in 1934, desomorphine was used in Switzerland under the brand name Permonid〔(【引用サイトリンク】 Krokodil )〕 and was described as having a fast onset and a short duration of action, with relatively little nausea or respiratory depression compared to equivalent doses of morphine. Dose-by-dose it is eight to ten times more potent than morphine.〔
Desomorphine is derived from morphine where the 6-hydroxyl group and the 7,8 double bond have been reduced.〔 The traditional synthesis of desomorphine starts from α-chlorocodide, which is itself obtained by reacting thionyl chloride with codeine. By catalytic reduction, α-chlorocodide gives dihydrodesoxycodeine, which yields desomorphine on demethylation.
