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.
描述了具有抗胆碱作用的呋喃酮化合物和组合物。这些化合物的化学式为:##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可以相同也可以不同,可以是氢、噻吩基、呋喃基、环丙烷基(C.sub.3 -C.sub.6)、苄基、苯基、取代苯基或取代苄基,其中苯基或苄基可能被卤素、三氟甲基、低烷基、低烷氧基或羟基取代;R.sub.3、R.sub.4和R.sub.5可以相同也可以不同,可以是氢、低烷基、带有卤素、烷氧基、氨基或羧酸基的取代低烷基,R.sub.4和R.sub.5之间或R.sub.3和环N之间的烷基或烷基烯桥,三氟甲基、硝基、含有3至6个碳原子的环丙烷基、卤素、苄基、苯基、取代苯基或取代苄基,其取代基与R.sub.1和R.sub.2中所述的相同,取代苄基或苯基。二氢呋喃酮系列中的R.sub.6是氢或低烷基。还描述了这些化合物的药用可接受的季铵烷基和酸盐。这些化合物在治疗神经源性膀胱障碍和慢性阻塞性肺疾病方面特别有用。
