Pharmacologically active R(-) 3-quinuclidinol derivatives are described which are muscarinic receptor blocking agents useful for the treatment of gastrointestinal and respiratory tract disorders of the following formula (I)
wherein
R represents a linear or branched lower alkyl group, a cycloalkyl-C₁₋₂alkyl or an aralkyl group, or it is absent;
X represents the anion of an organic or inorganic acid, or it is absent, when R is absent;
R₁ represents H, a linear or branched lower alkyl group or an acyl group of the type R₂-CO, in which R₂ is H or a linear or branched lower alkyl group;
A represents a cycloalkyl, an aromatic ring or a 5- or 6-membered heterocyclic ring;
Y and Z may be simultaneously or alternatively present or absent; when they are simultaneously present, they represent oxygen; when only one of them is present, it is oxygen or sulphur;
n is 1, 2 or 3;A and the 3-quinuclidinyl ester groups are inserted simultaneously on the same carbon atom of the ring to give rise to a geminal substitution.The process of the preparation of the compounds of formula (I) as well as pharmaceutical compositions containing them are also described.
本文描述了具有药理活性的R(-) 3-喹诺啡醇衍生物,它们是肌肉型受体阻滞剂,可用于治疗以下化学式(I)中的胃肠道和呼吸道疾病,其中:R表示线性或支链低级烷基,环烷基-C₁₋₂烷基或芳基烷基,或者它不存在;X表示有机或无机酸的阴离子,或者当R不存在时,它不存在;R₁表示H,线性或支链低级烷基或R₂-CO类型的酰基,其中R₂为H或线性或支链低级烷基;A表示环烷基,芳香环或5-或6-成员杂环;Y和Z可以同时或交替存在或不存在;当它们同时存在时,它们表示氧;当只有其中之一存在时,它是氧或硫;n为1、2或3;A和3-喹诺啡醇酯基同时插入环的同一碳原子上,形成双基取代。本文还描述了化学式(I)化合物的制备过程以及含有它们的制药组合物。
