The invention provides new substituted amides of formula: R--CONH--Het in which: either R is cycloalkyl (3 to 6 carbons), cyclohexadienyl, phenyl, substituted phenyl or a heterocyclic systems chosen from 3-pyridyl, alkyloxy-3-pyridyl, thienyl, alkylthienyl, furyl, tetrahydropyridyl, pyridazinyl, and alkylpyridazinyl, and Het is 1,8-naphthyridin-2-yl substituted at the 7-position by alkyloxy, alkylthio or alkylsulphinyl, themselves substituted with alkylamino or dialkylamino (in which the alkyl portions can form, with the nitrogen atom, a 5- or 6-membered heterocyclic system optionally containing another hetero atom chosen from O, S or N, and optionally substituted by alkyl) or by dialkylcarbamoyl or N-alkyl-N-(alkyloxycarbonyl)amino, or substituted at the 7-position by dialkylaminovinyl; or R is 4-(alkylamino)phenyl or 4-(alkyloxycarbonylamino)phenyl and Het is 1,8-naphthyridin-2-yl substituted at the 7-position by alkyloxy or alkylthio, the said alkyl radicals and alkyl portions containing 1 to 4 carbons, their salts, their preparations and pharmaceutical compositions which contain them. These new substituted amides are especially active as anxiolytics, hypnotics, anticonvulsants, antiepileptics and muscle relaxants.
该发明提供了新的取代酰胺,其化学式为:R--CONH--Het,在其中:R为环烷基(3至6个碳原子)、环己二烯基、苯基、取代苯基或从3-吡啶基、烷氧基-3-吡啶基、噻吩基、烷基噻吩基、呋喃基、四氢吡啶基、吡啶并嘧啶基和烷基吡啶并嘧啶基中选择的杂环系统,Het为在7位被烷氧基、烷硫基或烷磺基取代的1,8-萘啶-2-基,它们本身被烷基氨基或二烷基氨基取代(其中烷基部分可以与氮原子形成含有另一杂原子(O、S或N)的5-或6-成员杂环系统,并且可以被烷基取代)或被二烷基氨基甲酰或N-烷基-N-(烷氧羰基)氨基取代,或在7位被二烷基氨基乙烯基取代;或R为4-(烷基氨基)苯基或4-(烷氧羰基氨基)苯基,Het为在7位被烷氧基或烷硫基取代的1,8-萘啶-2-基,所述的烷基基团和烷基部分含有1至4个碳原子,它们的盐、它们的制备物和含有它们的药物组合物。这些新的取代酰胺在抗焦虑、催眠、抗抽搐、抗癫痫和肌肉松弛剂方面特别活跃。
