The invention relates to new pyrido[3,2-e]-as-triazine derivatives of the formula I and pharmaceutically acceptable acid addition salts thereof, ##STR1## wherein R.sub.1 stands for a C.sub.1-20 alkyl-carbonyl group, halogen-C.sub.1-4 alkyl-carbonyl, benzoyl, phenyl-C.sub.1-4 alkyl-carbonyl, or pyridyl-carbonyl group; R.sub.2 is a hydrogen atom or a C.sub.1-4 alkyl-carbonyl group; or R.sub.1 and R.sub.2 form together with the adjacent nitrogen atoms a pyrazole-2,4-dione ring which carries a C.sub.1-6 alkyl substituent in position 3; R.sub.3 is a hydrogen atom, a C.sub.1-20 alkyl, phenyl, phenyl-C.sub.1-3 alkyl, furyl or pyridyl group or a phenyl group optionally substituted by one to three C.sub.1-4 alkoxy-groups. The compounds of the formula I are prepared by acylating the respective 1,2-un-substituted 1,2-dihydropyrido [3,2-e]-as-triazine derivatives. The new compounds exert valuable effects on the central nervous system and possess analgesic, antiphlogistic effects, and can be applied to advantage in therapy.
本发明涉及公式I的新的吡啶并[3,2-e]-三嗪衍生物及其药学上可接受的酸加成盐,其中:
##STR1##
其中,R1代表C1-20烷基羰基,卤代C1-4烷基羰基,苯甲酰基,苯基-C1-4烷基羰基或吡啶基羰基;
R2是氢原子或C1-4烷基羰基;或者R1和R2与相邻氮原子一起形成一个嘧啶-2,4-二酮环,在3位上带有C1-6烷基取代基;
R3是氢原子,C1-20烷基,苯基,苯基-C1-3烷基,呋喃基或吡啶基或一个苯基,其可选地被一个到三个C1-4烷氧基取代。
公式I的化合物通过酰化相应的1,2-未取代1,2-二氢吡啶[3,2-e]-三嗪衍生物制备。这些新化合物对中枢神经系统具有有价值的作用,具有镇痛、抗炎作用,并可优势地应用于治疗中。
