There are described compounds of formula I, ##STR1## in which X is O, S or N--R.sub.7, each Y, which may be the same or different, is H, OH, alkyl C1-C8, alkoxy C1-C8 or halogen, n is an integer from 1 to 4 inclusive, R and R.sub.1, which may be the same or different, are each H; alkanoyl C2-C8 or a group R.sub.4 in which R.sub.4 is alkyl C1-C8 optionally substituted by phenyl; or is cycloalkyl C5 or C6; or is a group of formula XVI, ##STR2## in which W and Z, which may be the same or different, are each H, OH, alkoxy C1-C8, phenyl-alkoxy C7 to C10, alkyl C1-C8, halogen, --NR.sub.2 R.sub.3, --COOR.sub.2, NO.sub.2, alkanoyloxy C2-C8, or --OCH.sub.2 CH.sub.2 NR.sub.2 R.sub.3, and R.sub.2, R.sub.3 and R.sub.7, which may be the same or different, are each H or alkyl C1-C8, provided that when X is N--R.sub.7 and R is H, then R.sub.1 is not (a) H when any Y groups are H, alkyl C1-C8, alkoxy C1-C8 or halogen, or (b) unsubstituted phenyl when all Y groups are H, and pharmaceutically acceptable salts thereof. There is also described the formulation and use of the compounds as pharmaceuticals, and processes for their production.
描述了化合物的化学式I,其中X为O、S或N-R.sub.7,每个Y可能相同也可能不同,为H、OH、烷基C1-C8、烷氧基C1-C8或卤素,n为1到4的整数,R和R.sub.1可能相同也可能不同,分别为H、烷酰基C2-C8或基团R.sub.4,其中R.sub.4为烷基C1-C8,可选择地被苯基取代;或者为环烷基C5或C6;或者为化学式XVI的基团,其中W和Z可能相同也可能不同,分别为H、OH、烷氧基C1-C8、苯基-烷氧基C7到C10、烷基C1-C8、卤素、-NR.sub.2R.sub.3、-COOR.sub.2、NO.sub.2、烷酰氧基C2-C8或-OCH.sub.2CH.sub.2NR.sub.2R.sub.3,且R.sub.2、R.sub.3和R.sub.7可能相同也可能不同,分别为H或烷基C1-C8,只要当X为N-R.sub.7且R为H时,R.sub.1不是(a) H,当任何Y基团为H、烷基C1-C8、烷氧基C1-C8或卤素时,或者(b) 未取代的苯基,当所有Y基团为H时,以及其药用盐。还描述了这些化合物的配方和用途作为药物,以及它们的生产工艺。
