The present invention includes compounds represented by the formula: ##STR1## wherein X is O or S; R.sub.1 and R.sub.2 are independently selected from the group consisting of hydrogen, hydroxy, halo, loweralkoxy, thioalkoxy and loweralkyl; or R.sub.1 and R.sub.2 taken together can form a methylenedioxy or ethylenedioxy bridge; R.sub.3 is loweralkyl; R.sub.4 is selected from ##STR2## wherein Y is O or S, R.sub.6 is hydrogen, methoxy or halo and m is 0 or 1; R.sub.5 is hydrogen, loweralkyl, phenyl or substituted phenyl wherein the phenyl ring is substituted with one, two or three substituents independently selected from loweralkyl, halo, hydroxy, loweralkoxy, amino and thioalkoxy; and R.sub.8 hydrogen or R.sub.3 and R.sub.8 taken together form a pyrrolidine ring; or a pharmaceutically acceptable salt thereof.
本发明包括以下式子所代表的化合物:##STR1## 其中X为O或S;R1和R2分别选自氢、羟基、卤素、低碳基氧基、硫基低碳基氧基和低碳基;或者R1和R2可以共同形成甲亚氧基或乙亚氧基桥;R3为低碳基;R4选自##STR2## 其中Y为O或S,R6为氢、甲氧基或卤素,m为0或1;R5为氢、低碳基、苯基或取代苯基,其中苯环上独立选择一个、两个或三个取代基,所选取代基为低碳基、卤素、羟基、低碳基氧基、氨基和硫基低碳基氧基;R8为氢或R3和R8共同形成吡咯烷环;或其药学上可接受的盐。
