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.
本发明涉及具有以下结构的N-含杂环化合物:##STR1## 其中R.sub.1和R.sub.2分别是氢、卤素、芳基、较低烷基、卤代(较低)烷基或亚硝基,R.sub.3是较低烷基,R.sub.4和R.sub.5分别是较低烷基,X是CH或N,Y是S、O、NH、C.dbd.N--OH或CO,Z是O或NH,A是氢、亚硝基、酰胺基,或##STR2## 中的一种,其中R.sub.6和R.sub.7分别是氢、较低烷基、酰基或可能被酯化羧基取代的较低烷基酰胺基,或者是--N.dbd.R.sub.8的一种,其中R.sub.8是可能被芳基取代的较低烷基亚烷基,该芳基可能被适当取代基取代。这些化合物可用于治疗血栓形成、炎症或过敏性疾病。
