Papaverine is a drug that can be easily oxidized to papaverinol, papaveraldine and to recently discovered 2,3,9,10-tetramethoxy-12-oxo-12H-indolo[2,1-a]isoquinolinium chloride. In a strong alkaline medium the spectroscopic properties of this latter compound are modified indicating formation of a new compound. The isolation and structure elucidation of this compound as 2-(2-carboxy-4,5-dimethoxyphenyl)-6
罂粟碱是一种很容易被氧化为罂粟碱,罂粟碱和最近发现的2,3,9,10-四甲氧基-12-氧代-12 H-吲哚并[2,1 - a ]异喹啉氯化物的药物。在强碱性介质中,后一种化合物的光谱性质被修饰,表明形成了新化合物。据报道该化合物为2-(2-羧基-4,5-二甲氧基苯基)-6,7-二甲氧基异喹啉鎓内盐的分离和结构解析。
