Abstract

Substituted thienobenzodiazepinones of the general formula I ##STR1## [wherein R.sup.1 denotes a hydrogen atom (--H) or an alkyl radical with 1 to 4 carbon atoms; R.sup.2 represents a halogen atom (halo) or has one of the meanings of R.sup.1 ; R.sup.3 denotes a halogen atom (halo) or the group --N(R.sup.4)R.sup.5 ; R.sup.4 denotes an alkyl radical with 1 to 4 carbon atoms or an alkenyl radical with 3 to 5 carbon atoms; R.sup.5 has one of the meanings of R.sup.4 or represents the group --(CH.sub.2).sub.m --N(R.sup.6)R.sup.7 ; or R.sup.4 and R.sup.5, together with the nitrogen atom to which both are bonded, denote a morpholino group, a pyrrolidino group, a piperidino group, a hexahydroazepin-1-yl group, a piperazin-1-yl group (which is optionally substituted in the 4-position by a methyl, ethyl or benzyl group), a 2,4-dimethylpiperazin-1-yl group, or a hexahydro-1H-1,4-diazepin-1-yl group (which is substituted in the 4-position by a methyl or ethyl group); R.sup.6 denotes an alkyl group with 1 to 4 carbon atoms; R.sup.7 denotes an alkyl group with 1 to 4 carbon atoms; A denotes a straight-chain or branched alkylene group with 1 to 5 carbon atoms; and m denotes 2 or 3] and their acid-addition salts are new compounds. They either have a protective action on the stomach and intestine and are suitable for treating illnesses based on disorders of the stomach or intestine, or they are intermediates for preparing products having protective action. Processes for the preparation of the new pharmacologically-active compounds and of the intermediate products are presented.
