A class of benzothiazepine esters having structures related to that of diltiazem are provided which possess vasodilating activity while being virtually free of cardiodepressive effects. The esters are useful in the treatment of arterial hypertension and disturbances of the cerebral circulation.
The compounds have the general formula I
wherein
R represents hydrogen or an electronegative group (preferably a halogen atom, or a nitro, trifluoromethyl or methoxy group);
and
X is a hydrocarbyl group containing from 1 to 15 carbon atoms.
本研究提供了一类苯并硫氮杂卓酯,其结构与地尔硫卓有关,具有血管扩张活性,同时几乎没有心脏抑制作用。这些酯类可用于治疗动脉高血压和脑循环障碍。
这些化合物的通式为 I
其中
R 代表氢或负电性基团(最好是卤原子,或硝基、三氟甲基或甲氧基);
和
X 是含有 1 至 15 个碳原子的烃基。
