The present invention relates to compounds of the formula ##STR1## wherein A together with the two carbon atoms to which it is attached forms the group ##STR2## AND THE BROKEN LINE REPRESENTS THE DOUBLE BOND IN GROUP (A); R.sub.1 represents a lower alkyl group; R.sub.2 represents the residue of an aromatic heterocyclic ring containing from 1 to 4 hetero atoms, which may be substituted by one or two lower alkyl groups, or a phenyl group which may be substituted by halogen, hydroxy, lower alkyl, trifluoromethyl or lower alkoxy and R.sub.3 and R.sub.4 each represent a hydrogen atom or a lower alkyl group. Also provided are methods for their preparation. The thienothiazine derivatives provided by this invention have anti-flammatory, analgesic and antirheumatic activity.
本发明涉及以下式的化合物:其中A与其连接的两个碳原子一起形成该基团,而断裂的线代表基团(A)中的双键;R.sub.1代表较低的烷基基团;R.sub.2代表含有1至4个杂原子的芳香杂环环的残基,可能被一个或两个较低的烷基基团取代,或者是一个苯基,可能被卤素、羟基、较低的烷基、三氟甲基或较低的烷氧基取代,而R.sub.3和R.sub.4分别代表氢原子或较低的烷基基团。还提供了它们的制备方法。本发明提供的噻吩噻嗪衍生物具有抗炎、镇痛和抗风湿活性。
