The present invention relates to N-containing fused heterocyclic compounds of the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each hydrogen, halogen, aryl, lower alkyl, halo (lower) alkyl or nitro, R.sub.3 is lower alkylene, R.sub.4 and R.sub.5 are each lower alkylene, X is CH or N, Y is S, O, NH, C.dbd.N--OH or CO, Z is O or NH, and A is hydrogen, nitroso, amidino, a group of ##STR2## wherein R.sub.6 and R.sub.7 are each hydrogen, lower alkyl, acyl, or lower alkaneimidoyl which may be substituted with esterified carboxy, or a group of the formula: --N.dbd.R.sub.8, wherein R.sub.8 is lower alkylidene which may be substituted with aryl optionally substituted with suitable substituent(s). The compounds are useful for treatment of thrombosis, inflammation, or allergic disease.
本发明涉及公式为:##STR1##的含氮融合杂环化合物,其中R.sub.1和R.sub.2分别为氢、卤素、芳基、低烷基、卤代(低)烷基或硝基,R.sub.3为低烷基,R.sub.4和R.sub.5分别为低烷基,X为CH或N,Y为S、O、NH、C.dbd.N--OH或CO,Z为O或NH,A为氢、亚硝基、酰胺基、##STR2##的基团,其中R.sub.6和R.sub.7分别为氢、低烷基、酰基或低烷基亚胺基,其可以被酯化羧基取代,或者为--N.dbd.R.sub.8的基团,其中R.sub.8为低烷基亚烷基,其可以被适当取代的芳基取代。这些化合物对于治疗血栓形成、炎症或过敏疾病有用。
