The present invention includes compounds represented by the formula:
wherein X is O or S;
R₁ and R₂ are independently selected from the group consisting of hydrogen, hydroxy, halo, loweralkoxy, thioalkoxy and loweralkyl; or R₁ and R₂ taken together can form a methylenedioxy or ethylenedioxy bridge;
R₃ is loweralkyl;
R₄ is selected from
wherein Y is O or S, R₆ is hydrogen, methoxy or halo and m is 0 or 1;
R₅ 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
R₈ is hydrogen or R₃ and R₈ taken together form a pyrrolidine ring; or a pharmaceutically acceptable salt thereof.
本发明包括由式表示的化合物:
其中 X 是 O 或 S;
R₁和R₂独立地选自氢、羟基、卤代、低级烷氧基、硫代烷氧基和低级烷基组成的组;或R₁和R₂合在一起可形成亚甲二氧基或亚乙二氧基桥;
R₃ 是低级烷基;
R₄ 选自
其中 Y 为 O 或 S,R₆ 为氢、甲氧基或卤代,m 为 0 或 1;
