The invention concerns novel, pharmaceutically useful compounds of formula I in which Q is a 5-membered heteroaryl optionally bearing 1 or 2 substituents independently selected from (1-4C)alkyl and halogeno; R.sup.1 is hydrogen, (1-6C)alkyl, or (1-4C)alkanoyl; R.sup.2 (when not as hereinbelow defined together with X) is hydrogen, (3-12C)cycloalkyl, (3-6C)alkenyl, phenyl(3-6C)alkenyl, tetrafluorophenyl, pentafluorophenyl, 5- or 6-membered heteroaryl, optionally substituted (1-6C)alkyl or optionally substituted phenyl; X is oxy, thio, sulphinyl, sulphonyl or an imino group of formula --NRa-- in which Ra is hydrogen, (1-6C)alkyl or together with R2 and the adjacent nitrogen atom forms a 4 to 6-membered saturated heterocyclic ring; and A is N or CT in which T is hydrogen or (1-4C)alkyl; or a pharmaceutically acceptable salt thereof; processes for the manufacture of the compounds and pharmaceutical compositions containing them. The compounds are useful as adenosine antagonists. The invention further provides novel intermediates useful in the manufacture of the compounds of formula I. ##STR1##
该发明涉及公式I中具有药用价值的新化合物,其中Q是一个5-成员杂芳基,可选地携带1或2个取代基,独立选择自(1-4C)烷基和卤素;R.sup.1是氢,(1-6C)烷基或(1-4C)烷酰基;R.sup.2(当不与X一起定义如下时)是氢,(3-12C)环烷基,(3-6C)烯基,苯基(3-6C)烯基,四氟苯基,五元或六元杂芳基,可选择取代的(1-6C)烷基或可选择取代的苯基;X是氧,硫,亚硫酰基,磺酰基或公式--NRa--中Ra是氢,(1-6C)烷基或与R2和相邻氮原子形成4到6-成员饱和杂环的环状结构的氮原子;A是N或CT,其中T是氢或(1-4C)烷基;或其药用可接受盐;制备这些化合物的方法和含有它们的药物组合物。这些化合物可用作腺苷拮抗剂。该发明还提供了在制备公式I化合物中有用的新中间体。
