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.
本发明涉及以下式的新化合物,其中虚线表示可选键:##STR1##其中“het”表示一个五元杂环,可能包括1或2个双键和1-4个从氮、氧或硫中选择的杂原子,但“het”不能表示1,2,4-或1,3,4-噁二唑;R.sup.1选择自氢、较低的烷基,可选地取代为苯基,苯基可能被卤素、较低的烷基或较低的烷氧基取代,或者是一个基团R.sup.6--CO--NH--CH.sub.2--或R.sup.6--O--CO--,其中R.sup.6是较低的烷基、支链或直链,或者是可选地取代为卤素、三氟甲基、较低的烷基、羟基、较低的烷氧基或较低的酰氧基的苯基;R.sup.2和R.sup.3相同或不同,各自代表氢、较低的烷基、环烷基(3-6个碳原子)、较低的烯基、较低的烷二烯基、较低的炔基,可选地取代为羟基、卤素或苯基,其中苯基可能被卤素、三氟甲基、较低的烷基、羟基或较低的烷氧基取代;R.sup.2和R.sup.3还可以分别选择三氟甲基或可选地取代为卤素、三氟甲基、较低的烷基、羟基、较低的烷氧基或较低的酰氧基的苯基,或者R.sup.2和R.sup.3可以分别是一个基团OR.sup.7或SR.sup.7,其中R.sup.7定义为R.sup.2或R.sup.3,如果“het”包括2个或更多个碳原子,则R.sup.4和R.sup.5相同或不同,各自定义为R.sup.2或R.sup.3,如果“het”只包括一个碳原子,则在杂环上只有一个取代基R.sup.4,R.sup.4定义为R.sup.2或R.sup.3,以及其单独的立体异构体和药学上可接受的酸盐。此外,本发明还涉及制备式I化合物的方法,新的中间体,含有相同化合物的药物组合物,以及通过给予式I化合物的非毒性有效量来治疗由乙酰胆碱(AcCh)或肌碱系统功能障碍引起的疾病的方法。
