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##
本发明涉及一种新型的药用化合物,其化学式为I,其中Q是一种5-成员的杂环芳基,可选地带有1或2个独立选择的取代基,所述取代基选自(1-4C)烷基和卤素;R.sup.1是氢、(1-6C)烷基或(1-4C)酰基;当R.sup.2(不与X在此下文中定义的情况下)是氢、(3-12C)环烷基、(3-6C)烯基、苯基(3-6C)烯基、四氟苯基、五氟苯基、5-或6-成员的杂环芳基、可选地取代的(1-6C)烷基或可选地取代的苯基时,X是氧、硫、亚砜基、磺酰基或式为--NRa--的亚胺基,其中Ra是氢、(1-6C)烷基或与R2和相邻的氮原子形成4到6-成员饱和杂环的环状结构;A是N或CT,其中T是氢或(1-4C)烷基;或其药学上可接受的盐;制造该化合物的过程以及含有该化合物的制药组合物。该化合物可用作腺苷拮抗剂。该发明还提供了制造化合物I的新型中间体。
