The present invention relates to the products of general formula: ##STR1## in which: R represents a straight or branched alkyl group having from 2 to 5 atoms of carbon, or the group ##STR2## represents a morpholino or piperidino group possibly substituted by 1 or 2 methyl groups; n=2 or 3; R.sub.1 and R.sub.2 considered independently each represent hydrogen or a lower alkyl group (1 to 4 carbon atoms) or R.sub.1 and R.sub.2 taken together represent a (CH.sub.2).sub.m group where m=4 or 5, R.sub.3 being equal to H or R.sub.1 is H and R.sub.2 and R.sub.3 considered together represent (CH.sub.2).sub.p where p is 3 or 4 the butyrolactone cycle substitutes the pyridyl group in 2', 3' or 4' position, the salts, isomers and mixtures of isomers of said products; and to a process for preparing said products and to the myocardium-protecting drugs containing same.
本发明涉及一般式的产品:##STR1##
其中:R代表具有2至5个碳原子的直链或支链烷基,或者##STR2##代表可能被1或2个甲基基团取代的吗啡啶或哌啶基团; n = 2或3; R.sub.1和R.sub.2分别独立地表示氢或较低的烷基(1到4个碳原子),或者R.sub.1和R.sub.2一起表示(CH.sub.2).sub.m基团,其中m = 4或5,R.sub.3等于H或R.sub.1为H且R.sub.2和R.sub.3共同表示(CH.sub.2).sub.p,其中p为3或4,丁内酯环替代2'、3'或4'位置的吡啶基团,所述产品的盐、异构体和异构体混合物;以及含有该产品的心肌保护药物的制备方法。
