Acylated pyrido \x9b3,4-e!-as-triazines of the formula (I), \n' ##STR1## wherein R.sub.1 stands for alkyl, alkoxy, haloalkyl, furyl, pyridyl, phenyl, phenyl-(C.sub.1-4 alkyl) or phyenyl-(C.sub.2-4 alkenyl) optionally substituted. R.sub.2 stands for hydrogen or a group of the formula R.sub.1 --CO--, R.sub.3 stands for hydrogen, a phenyl group or a naphthy6l group optionally substituted, or a phenyl-(C.sub.1-4 alkyl) group, pyridyl group or a C.sub.1-20 alkyl group, and R.sub.4 stands for hydrogen or a group of the formula R.sub.1 --CO--, and R.sub.5 forms together with R.sub.2 or R.sub.4 a valence bond, wherein R.sub.2 or R.sub.4 taking part in forming said valence bond may not have the above meaning, and pharmaceutically acceptable acid addition salts thereof, which are prepared by reacting a pyrido \x9b3,4-e!-as-triazine of the formula (II) or an acid addition salt \n' thereof ##STR2## R.sub.6 stands for hydrogen, and R.sub.5 forms together with R.sub. and R.sub.4 a valence bond, with an acylating agent of the formula (III). R.sub.1 --CO--X (III) The compounds exert favourable effects on the central nervous system, and can be applied primarily as analgesic and antiphlogistic agents.
公式(I)的酰化吡啶\x9b3,4-e!-三嗪,其中R.sub.1代表烷基,烷氧基,卤代烷基,呋喃基,吡啶基,苯基,苯基-(C.sub.1-4烷基)或苯基-(C.sub.2-4烯基),可选择地取代。R.sub.2代表氢或具有公式R.sub.1 --CO--的基团,R.sub.3代表氢,苯基或可选择地取代的萘基,或苯基-(C.sub.1-4烷基)基团,吡啶基或C.sub.1-20烷基基团,R.sub.4代表氢或具有公式R.sub.1 --CO--的基团,R.sub.5与R.sub.2或R.sub.4一起形成一个价键,其中参与形成所述价键的R.sub.2或R.sub.4可能没有上述含义,并且其药学上可接受的酸盐,通过将公式(II)的吡啶\x9b3,4-e!-三嗪或其酸盐与具有公式(III)的酰化试剂反应制备而成。R.sub.6代表氢,R.sub.5与R.sub.2和R.sub.4一起形成一个价键,这些化合物对中枢神经系统有良好的作用,并主要可用作镇痛和抗炎药剂。
