Thiazolo[3, 2-a]thieno[3, 2-d]-, [3, 4-d]- and [2, 3-d]pyrimidin-5-one derivatives (6, 11, and 16), and polymethylene condensed thieno[3, 2-d]-, [3, 4-d]- and [2, 3-d]pyrimidin-5-one derivatives (19-21), in which the oxygen atom of the oxazolidine moiety in 3 was replaced by a sulfur atom or methylene groups, were synthesized and evaluated for gastric antisecretory activity in pylorus-ligated rats. The structure-activity relationships of these compounds are discussed.
合成并评估了噻唑并噻吩和嘧啶-5-酮衍生物(6、11和16)以及多亚甲基缩合的噻吩-和嘧啶-5-酮衍生物(19-21),其中在3的噁唑烷环中的氧原子被硫原子或亚甲基取代,并对在幽门结扎大鼠中进行的胃抗分泌活性进行了评估。文中讨论了这些化合物的结构-活性关系。
