The invention relates to novel pyrimidinone compounds of anti-allergic and cardiotonic activity of the formula: ##STR1## wherein R.sup.1 and R.sup.2 are each lower alkyl, lower alkoxycarbonyl(lower)alkyl, carboxy(lower)alkyl or di(lower)alkylamino(lower)alkyl, R.sup.3 is hydroxy, lower alkoxy, halo(lower)alkoxy, lower alkylthio, lower alkanesulfinyl, lower alkanesulfonyl, nitro, amino or di(lower)alkanesulfonylamino, R.sup.4 is hydroxy, lower alkoxy, halo(lower)alkoxy, lower alkoxycarbonyl(lower)alkoxy or carboxy(lower)alkoxy, or R.sup.3 and R.sup.4 are taken together to form lower alkylenedioxy or lower alkylidenedioxy, R.sup.5 is phenyl substituted with 1 to 4 substituents selected from the group consisting of lower alkyl and sulfamyl, R.sup.10 is hydrogen or sulfamyl, provided that when both of R.sup.1 and R.sup.2 are lower alkyl and R.sup.3 and R.sup.4 are lower alkoxy, then R.sup.10 is sulfamoyl, and that when R.sup.3 is hydroxy, then R.sup.4 is hydroxy, and pharmaceutically acceptable salts thereof.
该发明涉及一种新型嘧啶酮化合物,具有抗过敏和心脏强效作用,其化学式为:##STR1## 其中R.sup.1和R.sup.2各自为较低的烷基,较低的烷氧羰基(较低)烷基,羧基(较低)烷基或二(较低)烷基氨基(较低)烷基,R.sup.3为羟基,较低的烷氧基,卤素(较低)烷氧基,较低的烷基硫醇,较低的烷基磺酰亚胺基,较低的烷基磺酰基,硝基,氨基或二(较低)烷基磺酰胺基,R.sup.4为羟基,较低的烷氧基,卤素(较低)烷氧基,较低的烷氧羰基(较低)烷氧基或羧基(较低)烷氧基,或R.sup.3和R.sup.4一起形成较低的烷基二氧杂环或较低的烷基亚甲基二氧杂环,R.sup.5为苯基,其上取代有1至4个选自较低的烷基和磺酰基的取代基,R.sup.10为氢或磺酰基,但当R.sup.1和R.sup.2均为较低的烷基且R.sup.3和R.sup.4均为较低的烷氧基时,R.sup.10为磺酰基,当R.sup.3为羟基时,R.sup.4为羟基,以及其药学上可接受的盐。
