The invention relates to pharmaceutical preparations containing compounds of formula I ##STR1## in which X.sub.1 and X.sub.2, independently of each other, represent hydrogen, halogen, unsubstituted or substituted amino or a quaternary ammonium salt; etherified or esterified hydroxy; free, etherified, esterified or oxidized mercapto; nitro; functionally modified formyl; free or functionally modified carboxyl; acyl; an unsubstituted or substituted hydrocarbon radical, or an unsubstituted or substituted heterocyclic radical; with the proviso that at least one of the radicals X.sub.1 and X.sub.2 is bonded by a carbon atom to the ring system and with the proviso that X.sub.1 and X.sub.2 cannot be together halogen and formyl; in which Y represents oxygen, sulfur, sulfinyl or sulfonyl but must be sulfur, sulfinyl or sulfonyl, if X.sub.1 is hydrogen and X.sub.2 is formyl, and the rings A and B are each unsubstituted or substituted; or pharmaceutically acceptable salts of such compounds that contain a salt-forming group, and to novel compounds of formula I. The compounds are useful e.g. for the treatment of diseases of the respiratory tract and of liver diseases. The are prepared by methods known per se.
本发明涉及含有式I的化合物的制药制剂:##STR1## 其中X.sub.1和X.sub.2独立地表示氢、卤素、未取代或取代的氨基或季铵盐;醚化或酯化羟基;自由、醚化、酯化或氧化的巯基;硝基;功能修饰的甲酰基;自由或功能修饰的羧基;酰基;未取代或取代的碳氢基团或未取代或取代的杂环基团。但是要注意,至少一个X.sub.1和X.sub.2基团通过碳原子与环系相结合,并且要注意X.sub.1和X.sub.2不能同时为卤素和甲酰基;其中Y表示氧、硫、亚硫酰基或磺酰基,但如果X.sub.1为氢且X.sub.2为甲酰基,Y必须为硫、亚硫酰基或磺酰基,并且环A和环B均未取代或取代;或者是包含有盐形成基团的这种化合物的药学上可接受的盐,以及式I的新化合物。这些化合物可用于治疗呼吸道疾病和肝脏疾病等。它们是通过已知的方法制备的。
