The present invention relates to 1,3,6,7-Tetrahydro-7-oxoimidazo[4,5-c][1,2,6]-thiadiazine 2-oxide derivatives of the general formula (I): ##STR1## wherein R.sub.1, R.sub.2 and R.sub.4 are the same or different and represent an alkyl group, an aryl group or an aralkyl group, each of which may have one or more substituents; and R.sub.3 represents a hydrogen atom, a halogen atom, an alkyl group, an aryl group or an aralkyl group, each of which group may have one or more substituents, and a process for their preparation. The imidazothiadiazine derivatives have hypotensive and vasodilating activities and can therefore be used as medicaments.
本发明涉及一般式(I)的1,3,6,7-四氢-7-氧代咪唑并[4,5-c][1,2,6]-噻二嗪2-氧衍生物:##STR1##其中R.sub.1,R.sub.2和R.sub.4相同或不同,表示烷基,芳基或芳基烷基,每个基团可能有一个或多个取代基; R.sub.3表示氢原子,卤素原子,烷基,芳基或芳基烷基,每个基团可能有一个或多个取代基,以及它们的制备方法。咪唑噻二嗪衍生物具有降压和扩张血管的活性,因此可以用作药物。
