The present invention relates to novel compounds of the following formula, where the dotted line designates an optional bond: ##STR1## wherein "het" designates a five membered heterocyclic ring which may include 1 or 2 double bonds and 1-4 heteroatoms selected from nitrogen, oxygen or sulphur, provided that "het" may not designate a 1,2,4- or 1,3,4-oxadiazole; R.sup.1 is selected from hydrogen, lower alkyl, optionally substituted with phenyl which may be substituted with halogen, lower alkyl, or lower alkoxy, or a group R.sup.6 --CO--NH--CH.sub.2 -- or R.sup.6 --O--CO--, wherein R.sup.6 is lower alkyl, branched or unbranched, or phenyl optionally substituted with halogen, trifluoromethyl, lower alkyl, hydroxy, lower alkoxy, or lower acyloxy; R.sup.2 and R.sup.3 are the same or different, each representing hydrogen, lower alkyl, cycloalkyl (3-6 C-atoms), lower alkenyl, lower alkadienyl, lower alkynyl, optionally substituted with hydroxy, halogen or phenyl, in which the phenyl group may be substituted with halogen, trifluoromethyl, lower alkyl, hydroxy or lower alkoxy; R.sup.2 and R.sup.3 may further, respectively, be selected from trifluoromethyl or phenyl optionally substituted with halogen, trifluoromethyl, lower alkyl, hydroxy, lower alkoxy or lower acyloxy, or R.sup.2 and R.sup.3 may, respectively, be a group OR.sup.7 or SR.sup.7 wherein R.sup.7 is defined as R.sup.2 or R.sup.3, and if "het" includes 2 or more carbon atoms, R.sup.4 and R.sup.5 are the same or different, and each is defined as R.sup.2 or R.sup.3, and if "het" includes only one carbon atom, there is only one substituent, R.sup.4, on the heterocyclic ring, and R.sup.4 is defined as R.sup.2 or R.sup.3, as well as individual stereo isomers and pharmaceutically acceptable acid addition salts thereof. The invention moreover relates to methods for the preparation of the compounds of formula I, to novel intermediates, to pharmaceutical compositions containing same and to methods for the treatment of disorders, caused by malfunction of the acetylcholine (AcCh) or muscarinic system, by administering a non-toxic effective amount of a compound of formula I.
本发明涉及下列公式的新化合物,其中点线表示可选键:##STR1## 其中“het”表示一个五元杂环环,可以包括1或2个双键和1-4个从氮、氧或硫选取的杂原子,但“het”不能表示1,2,4-或1,3,4-噁二唑;R.sup.1选自氢、低碳基,可选地取代苯基,该苯基可以被卤素、低碳基或低烷氧基取代,或者是一个R.sup.6-CO-NH-CH.sub.2-或R.sup.6-O-CO-基团,其中R.sup.6是低碳基,支链或直链,或者是可选地被卤素、三氟甲基、低碳基、羟基、低烷氧基或低酰氧基取代的苯基;R.sup.2和R.sup.3相同或不同,每个代表氢、低碳基、环戊烷基(3-6个碳原子)、低烯基、低二烯基、低炔基,可选地被羟基、卤素或苯基取代,其中苯基可以被卤素、三氟甲基、低碳基、羟基或低烷氧基取代;R.sup.2和R.sup.3还可以分别选自三氟甲基或可选地被卤素、三氟甲基、低碳基、羟基、低烷氧基或低酰氧基取代的苯基,或者R.sup.2和R.sup.3分别是OR.sup.7或SR.sup.7基团,其中R.sup.7定义为R.sup.2或R.sup.3,如果“het”包含2个或更多个碳原子,则R.sup.4和R.sup.5相同或不同,每个定义为R.sup.2或R.sup.3,如果“het”只包含一个碳原子,则杂环上只有一个取代基R.sup.4,且R.sup.4定义为R.sup.2或R.sup.3,以及其个别立体异构体和药学上可接受的酸加合物。此外,本发明还涉及制备公式I化合物的方法、新的中间体、含有该化合物的制药组合物以及通过给予公式I化合物的非毒性有效量来治疗由乙酰胆碱(AcCh)或肌动系统功能紊乱引起的疾病的方法。
