Abstract
Benzothiazole derivatives corresponding to the general formula I ##STR1## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 represent, independently of one another, a hydrogen atom, a halogen atom, a linear C.sub.1 -C.sub.3 -alkyl group or a linear C.sub.1 -C.sub.3 -alkoxy group, R.sup.5 represents a hydrogen atom or a linear C.sub.1 -C.sub.3 -alkyl group, R.sup.6 represents a hydrogen atom, and R.sup.7 represents a formyl group, a carbalkoxy group of the formula ##STR2## wherein R.sup.8 denotes a linear or branch chained C.sub.1 -C.sub.4 -alkyl group, or it represents an acyl group of the formula ##STR3## wherein R.sup.9 denotes a linear C.sub.1 -C.sub.3 -alkyl group, or R.sup.6 and R.sup.7 together represent the group ##STR4## wherein R.sup.10 and R.sup.11 represent, independently of one another, a hydrogen atom or a linear C.sub.1 -C.sub.6 -alkyl group or R.sup.6 and R.sup.7 represent the group ##STR5## wherein R.sup.12 and R.sup.13 represent, independently of one another, a linear C.sub.1 -C.sub.3 -alkyl group or a linear C.sub.1 -C.sub.3 -alkoxy group or R.sup.6 and R.sup.7 represent the group ##STR6## wherein R.sup.14 denotes a linear C.sub.1 -C.sub.3 -alkyl group, as well as the physiologically acceptable salts thereof, a process for the preparation of these compounds, and a pharmaceutical preparation containing them, are described.
