The invention provides new substituted amides of formula R--CONH--Het in which: either R is phenyl substituted by acyloxy, alkylthio or alkyloxycarbonylamino, or by chloro at the 2- or 4-position, or by two alkyloxy radicals, or R is 2- or 4-pyridyl, pyrazinyl, 5,6-dihydrodithiin-2-yl, 5,6-dihydrooxathiin-2-yl, 1,3-dithiolyl, thiazolyl or substituted thienyl or furyl, or R is alkenyl (of 2 to 4 carbons) unsaturated in the .alpha.-position to the amide carbonyl, and Het is 1,8-naphthyridin-2-yl substituted at the 7-position by halogen, alkyloxy, phenoxy, 3-chloro- or dichlorophenoxy, hydroxy or cyano, or R is methoxyphenyl and Het is 1,8-naphthyridin-2-yl substituted in the 7-position by 3-chloro- or dichlorophenoxy, hydroxy or cyano, or R is methoxy-3-pyridazinyl and Het is 1,8-naphthyridin-2-yl substituted at the 7-position by phenoxy, the said alkyl and acyl radicals containing 1 to 4 carbon atoms in a linear or branched chain, their preparation and the pharmaceutical compositions which contain them. These new amides are useful as anxiolytics, hypnotics and muscle relaxants.
本发明提供了新的取代酰胺化合物,其化学式为R-CONH-Het,其中:R可能是苯基,被酰氧基、烷硫基或烷氧羰基氨基、2-或4-位氯代基或两个烷氧基基团取代;或者R是2-或4-吡啶基、吡嗪基、5,6-二氢二硫杂环-2-基、5,6-二氢噁二杂环-2-基、1,3-二硫杂环基、噻唑基或取代的噻吩基或呋喃基;或者R是α-位不饱和的烯基(2到4个碳)与酰胺羰基相连;Het是1,8-萘啶-2-基,在7-位被卤素、烷氧基、苯氧基、3-氯代苯氧基或二氯代苯氧基、羟基或氰基取代;或者R是甲氧基苯基,Het是1,8-萘啶-2-基,在7-位被3-氯代苯氧基或二氯代苯氧基、羟基或氰基取代;或者R是甲氧基-3-吡唑基,Het是1,8-萘啶-2-基,在7-位被苯氧基取代。所述的烷基和酰基基团中,线性或支链链中含有1到4个碳原子。本发明还涉及这些新酰胺化合物的制备方法以及含有它们的药物组合物。这些新的酰胺化合物可用于治疗焦虑症、催眠药和肌肉松弛剂。
