Furanone compounds and compositions having anticholinergic activity are described. The compounds have the formula: ##STR1## wherein: the dashed line indicates either the 4,5-unsaturated or the 4,5-dihydrofuranone ring; R.sub.1 and R.sub.2 may be the same or different and are hydrogen, thienyl, furanyl, or cycloalkyl (C.sub.3 -C.sub.6), benzyl, phenyl, substituted phenyl or substituted benzyl wherein the phenyl or benzyl group may be substituted with halogen, trifluoromethyl, lower alkyl, lower alkoxy or hydroxy; R.sub.3, R.sub.4 and R.sub.5 may be the same or different and are hydrogen, lower alkyl, lower alkyl substituted with a halogen, alkoxy, amino or carboxylic acid group, an alkyl or alkylene bridge between R.sub.4 and R.sub.5 or R.sub.3 and the ring N, trifluoromethyl, nitro, a cycloalkyl group containing 3 to 6 carbons, halogen, benzyl, phenyl, substituted phenyl or substituted benzyl, for which the substituents are the same as those set forth for R.sub.1 and R.sub.2 substituted benzyl or phenyl. R.sub.6 in the dihydrofuranone series is hydrogen or lower alkyl. Also described are the pharmaceutically acceptable quaternary alkyl and acid addition salts of such compounds. The compounds are particularly useful in the treatment of neurogenic bladder disorder and chronic obstructive pulmonary diseases.
本文描述了具有抗胆碱作用的呋喃酮化合物和组合物。该化合物的化学式为:##STR1## 其中:虚线表示4,5-不饱和或4,5-二氢呋喃酮环; R.sub.1和R.sub.2可以相同或不同,可以是氢、噻吩基、呋喃基或环烷基(C.sub.3-C.sub.6)、苯甲基、苯基、取代苯基或取代苯甲基,其中苯基或苯甲基可以被卤素、三氟甲基、低碳基、低碳氧基或羟基取代;R.sub.3、R.sub.4和R.sub.5可以相同或不同,可以是氢、低碳基、被卤素、烷氧基、氨基或羧酸基取代的低碳基、R.sub.4和R.sub.5或R.sub.3和环N之间的烷基或烷基桥、三氟甲基、硝基、含3至6个碳的环烷基、苯甲基、苯基、取代苯基或取代苯甲基,其中取代基与R.sub.1和R.sub.2中的取代基相同。二氢呋喃酮系列中的R.sub.6是氢或低碳基。还描述了这些化合物的药物可接受的季铵基和酸加成盐。这些化合物在神经源性膀胱障碍和慢性阻塞性肺疾病的治疗中特别有用。
