This invention relates to the novel 1,6-naphthyridine derivatives useful as antidinic and/or cerebral circulation improver, such novel derivatives being represented by the following general formula: ##STR1## (wherein R is a C.sub.2-10 alkyl which may have hydroxyl, lower alkylcarbonyl, lower alkyloxycarbonyl or phenoxy as a substituent; a C.sub.2-10 unsaturated aliphatic hydrocarbon group having unsaturated double bond(s); a phenyl-lower alkyl which may have halogen, lower alkyl, lower alkoxy or lower alkylthio as substituent(s) attached to the phenyl ring; a cinnamyl which may have halogen, nitro, lower alkyl or lower alkoxy as substituent(s) attached to the phenyl ring; propargyl; 1-naphthylmethyl; 2-thenyl; cyclohexenyl; a cycloalkyl-lower alkyl with a 3- to 6-membered ring; 1/2(C.sub.2-4 alkylene); 1/2(butenylene), or diphenylmethyl, and in case two alkoxyl groups are present attached to the phenyl ring, they may be bonded to form a ring) and salt thereof.
这项发明涉及新颖的1,6-萘啶衍生物,可用作抗晕和/或改善脑循环的药物,这种新颖的衍生物由以下一般式代表:##STR1##(其中R是一个C.sub.2-10烷基,可能具有羟基,较低烷基羰基,较低烷氧羰基或苯氧基作为取代基;一个具有不饱和双键的C.sub.2-10不饱和脂肪烃基;一个苯基-较低烷基,可能具有卤素,较低烷基,较低烷氧基或较低烷硫基作为取代基附着在苯环上;一个肉桂基,可能具有卤素,硝基,较低烷基或较低烷氧基作为取代基附着在苯环上;丙炔基;1-萘甲基;2-茚基;环己烯基;具有3-至6-成员环的环烷基-较低烷基;1/2(C.sub.2-4烷基);1/2(丁烯基),或二苯甲基,如果有两个烷氧基附着在苯环上,它们可以连接形成一个环)及其盐。
