As a part of our studies on the structure-activity relationship of 1, 3-disubstituted 5-dialkylamino-6-methyluracil derivatives, we have synthesized 1, 3-disubstituted 5-dialkylaminomethyl-6-methyluracils (B). In the synthesis, 1, 3-disubstituted 5-cyano-uracils (1-6) were hydrogenated with Raney-cobalt followed by methylation to give the 5-dimethylaminomethyluracil compounds (16-20). The Mannich reaction of 1, 3-disubstituted uracils (23-26, 33) did not proceed, but halogenomethylation of them and subsequent amination gave the 5-dialkylaminomethyl compounds (20, 34-41). As to their pharmacological activities, analgetic, antipyretic and antiinflammatory activities and acute toxicity were tested. The compounds (B) showed only antiinflammatory activity.
作为 1,3-二取代 5-二烷基氨基-6-甲基尿嘧啶衍生物结构-活性关系研究的一部分,我们合成了 1,3-二取代 5-二烷基氨基甲基-6-甲基尿嘧啶 (B)。在合成过程中,1, 3-二取代的 5-氰基-脲嘧啶(1-6)先用雷尼钴氢化,然后甲基化,得到 5-二甲氨基甲基脲嘧啶化合物(16-20)。1,3-二取代尿嘧啶(23-26,33)的曼尼希反应没有进行,但对它们进行卤代甲基化,然后进行胺化,得到了 5-二烷基氨基甲基化合物(20,34-41)。在药理活性方面,对这些化合物的镇痛、解热和抗炎活性以及急性毒性进行了测试。化合物(B)只显示出抗炎活性。
