The novel pyridone derivatives of the formula ##STR1## wherein Ra is hydrogen or halogen, Rb is --NR.sup.2 R.sup.3 wherein R.sup.2 and R.sup.3 taken together with the nitrogen atom to which they are attached is a 1-azetidinyl, 1-pyrrolidinyl, 1-piperidinyl which is unsubstituted or mono- or disubstituted by lower alkyl, hydroxy, lower alkoxy, lower hydroxyalkyl, lower alkoxyalkyl or phenyl; B and the carbon atom denoted by .alpha. taken together is a group of the formula >C.sub..alpha. --CR.sup.4 .dbd.CH--CH.dbd.CH-- and R.sup.4 is hydrogen, fluorine or chlorine, can be used for the control or prevention of illnesses. In particular, they have muscle relaxant, sedative-hypnotic, anxiolytic and/or anticonvulsive activity and can accordingly be used in the control or prevention of muscle tensions, stress conditions, insomnia, anxiety states and/or convulsions.
该小说的吡啶酮衍生物的公式为##STR1##其中Ra是氢或卤素,Rb是--NR.sup.2 R.sup.3,其中R.sup.2和R.sup.3与它们所连接的氮原子一起是未取代或被低烷基,羟基,低烷氧基,低羟基烷基,低烷氧基烷基或苯基单取代或双取代的1-氮杂环丙基,1-吡咯烷基,1-哌啶基; B和表示α的碳原子一起是公式>C.sub..alpha. --CR.sup.4 .dbd.CH--CH.dbd.CH--的基团,其中R.sup.4是氢,氟或氯,可用于控制或预防疾病。特别地,它们具有肌肉松弛,镇静催眠,抗焦虑和/或抗惊厥活性,因此可以用于控制或预防肌肉紧张,压力状态,失眠,焦虑状态和/或惊厥。
