compounds revealed good to excellent activities against colon carcinoma cell lines (HCT-116) and human Hepatocellular carcinoma cell lines (HePG-2). Compounds 5 and 10-12 showed higher antiproliferative activity (from 2.68 to 16.82 µg/mL) against the two types of cancer cell lines as compared with the reference drug (5-fluoeouracil). Quantitative structure activity relationship (QSAR models) were created
6-Amino-5-formyluracil ( 1 ) 被有效地用于构建多种新型异环嘧啶。化合物1与一些环状活性亚甲基酮(包括 1,3-环己二酮、二甲酮、1,3-茚满二酮、取代的吡唑啉酮、1,3-噻唑烷-2,4-二酮和硫代巴比妥酸)的Friedländer 缩合反应得到多种稠合杂环吡啶并[2,3-d]嘧啶。化合物1与5-氨基-3-甲基-1 H-吡唑、6-氨基尿嘧啶和6-氨基-1,3-二甲基尿嘧啶等环状烯胺反应生成吡唑并[4',3':5,6]吡啶并[ 2,3-d]嘧啶和嘧啶并[5',4':5,6]吡啶并[2,3-d]嘧啶。此外,化合物1的反应与一些杂环烯醇即 4-hydroxycoumarin、1-ethyl-4-hydroxyquinolin-2(1 H )-one 和 2-hydroxy-4 H -pyrido[1,2-a]pyrimidin-4-one 产生多种 polyfused系统。在
