The invention relates to thiazole derivatives with the general formula I ##STR1## wherein R.sup.1 is halogen, CF.sub.3, CN, NO.sub.2, OH or C.sub.1 -C.sub.6 alkoxy; R.sup.2 is hydrogen, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, aryl, C.sub.6 -C.sub.13 aralkyl, an unsubstituted amino group, a substituted amino group, or an amino group which is part of a 5- or 6-membered ring; R.sup.3 is C.sub.1 -C.sub.6 hydrocarbon, C.sub.6 -C.sub.13 aralkyl, C.sub.2 -C.sub.7 alkoxyalkyl or C.sub.1 -C.sub.13 acyl; and their pharmaceutically acceptable acid addition salts. These new compounds have .alpha..sub.2 -antagonist activity without dopamine agonist activity and as such are specifically useful for the treatment of depression and other related illnesses, e.g. for treating patients with anxiety disorders and cognitive disturbances.
该发明涉及具有通式I的噻唑衍生物,其中R.sup.1是卤素,CF.sub.3,CN,NO.sub.2,OH或C.sub.1-C.sub.6烷氧基;R.sup.2是氢,C.sub.1-C.sub.6烷基,C.sub.1-C.sub.6烷氧基,芳基,C.sub.6-C.sub.13芳基烷基,未取代的氨基,取代的氨基或作为5-或6-成员环的氨基;R.sup.3是C.sub.1-C.sub.6碳氢化合物,C.sub.6-C.sub.13芳基烷基,C.sub.2-C.sub.7烷氧基烷基或C.sub.1-C.sub.13酰基;以及它们的药学上可接受的酸盐。这些新化合物具有α2-拮抗活性而无多巴胺激动剂活性,因此特别适用于治疗抑郁症和其他相关疾病,例如用于治疗患有焦虑症和认知障碍的患者。
