The invention relates to new thieno-triazolo-1,4-diazepino-2-carboxylic acid amides of formula I ##STR1## wherein R.sub.1 represents hydrogen, a C.sub.1 -C.sub.4 straight-chained or branched alkyl which can optionally be substituted by halogen, preferably Cl or Br, or by hydroxy, cyclopropyl, C.sub.1 -C.sub.3 alkoxy, preferably methoxy, or halogen, preferably chlorine or bromine; R.sub.2 and R.sub.3, each independently, represent hydrogen, a C.sub.1 -C.sub.4 straight-chained or branched alkyl, C.sub.1 -C.sub.4 hydroxyalkyl or the two groups R.sub.2 and R.sub.3 together with the nitrogen atom represent a 5-, 6- or 7-membered ring which optionally contains a nitrogen, oxygen or sulfur atom as a further heteroatom, the second nitrogen atom optionally being substituted by a C.sub.1 -C.sub.4 alkyl, preferably a methyl group; R.sub.4 represents alpha-pyridyl or a phenyl in which the phenyl ring can be substituted preferably in the 2-position, by methyl, halogen, preferably chlorine or bromine, nitro or trifluoromethyl; n represents one of the numbers 0, 1, 2, 3, 4, 5, 6, 7 or 8; and novel intermediates therefor. The compounds of formula I are useful in the treatment of pathological conditions and diseases in which platelet activating factor is implicated.
本发明涉及公式I的新型噻唑咪唑并[1,4]二氮杂二环-2-羧酰胺化合物,其中R1代表氢、C1-C4直链或支链烷基,可以选择性地被卤素(优选的是氯或溴)或羟基、环丙基、C1-C3烷氧基(优选的是甲氧基)或卤素(优选的是氯或溴)取代;R2和R3各自独立地代表氢、C1-C4直链或支链烷基、C1-C4羟基烷基或R2和R3两个基团与氮原子一起代表一个5-、6-或7-成员环,该环可以选择性地包含氮、氧或硫原子作为进一步的杂原子,第二个氮原子可以选择性地被C1-C4烷基(优选的是甲基基团)取代;R4代表α-吡啶基或苯基,其中苯环可以选择性地在2-位被甲基、卤素(优选的是氯或溴)、硝基或三氟甲基取代;n代表0、1、2、3、4、5、6、7或8中的一个数字;以及其新型中间体。公式I的化合物在治疗与血小板活化因子有关的病理状况和疾病方面是有用的。
