New tricyclic ortho-fused heterocyclic compounds of formula
wherein A is the group R or the group N
in which R represents hydrogen, (C1-4) alkyl, phenyl or tolyl and R, may be (C1-4) alkyl, phenyl or tolyl, R2 is selected from (C1-4) alkyl, (C2-4) alkanoylmethyl, carbo- (C1-3) alkoxymethyl, hydroxy (C2-4) alkyl, halo (C2.4) alkyl and a group
wherein R3 is an alkylene group from 2 to 4 carbon atoms and R. and Rs independently represent hydrogen or (C1-4) alkyl or, taken together with the nitrogen atom, a fully hydrogenated 5 or 6 membered heterocyclic radical which may contain a further heteroatom selected from 0, N and S and be optionally substituted by a (C1-4) alkyl or phenyl group, or R2 may represent nil, the dotted lines x and y may represent nil or additional bonds; with the proviso that, when the symbol R2 linked to the oxygen atom is different from nil, x is an additional bond and y and the other symbol R2 represent nil; with the further proviso that. when the symbol R2 linked to the nitrogen atom is different from nil, y is an additional bond and x and the other symbol R2, represent nil; and salts therewith of pharmaceutically acceptable acids. The compounds possess antiinflammatory CNS-depressant and anti-anxiety utility.
式中的新三环正交融合杂环化合物
其中 A 是基团 R 或基团 N
其中 R 代表氢、(C1-4)烷基、苯基或甲苯基,R 可以是(C1-4)烷基、苯基或甲苯基,R2 选自(C1-4)烷基、(C2-4)烷酰甲基、羧基(C1-3)烷氧基甲基、羟基(C2-4)烷基、卤代(C2.4)烷基和一个基团
其中 R3 是 2 至 4 个碳原子的亚烷基,R.和 Rs 独立地代表氢或 (C1-4) 烷基,或与氮原子一起代表完全氢化的 5 或 6 位杂环基,该杂环基可包含选自 0、N 和 S 的另一个杂原子,并可选择被 (C1-4) 烷基或苯基取代,或 R2 可代表无,虚线 x 和 y 可代表无或附加键;附带条件是,当与氧原子相连的符号 R2 不同于 "无 "时,x 代表附加键,y 和另一个符号 R2 代表 "无";进一步的附带条件是。当与氮原子相连的符号 R2 与 "无 "不同时,y 是附加键,x 和另一个符号 R2 代表 "无";以及药学上可接受的酸的盐。这些化合物具有抗炎、中枢神经系统抑制和抗焦虑的作用。
