A synthesis of new 2,6-disubstituted and 2,6,8-trisubstituted 7-methylpurines as well as 8-substituted 3,7-dimethylxanthines containing a triple bond chain have been worked out. Purinethiones and xanthinethiones were converted into propynylthio derivatives, which were then further transformed via a Mannich reaction into aminobutynylthio derivatives (amine = pyrrolidine, piperidine, morpholine, and
合成了新的2,6-二取代的和2,6,8-三取代的7-甲基嘌呤以及含有三键链的8-取代的3,7-二甲基黄嘌呤。嘌呤硫酮和黄嘌呤硫酮被转化为丙炔硫基衍生物,然后通过曼尼希反应进一步转化为氨基丁炔硫基衍生物(胺=吡咯烷,哌啶,吗啉和二乙胺)。如此获得的产物代表各种类型的嘌呤和黄嘌呤结构:8-单-,2,6-和6,8-二丙炔硫基,6-和8-单氨基丁炔硫基,2,6-和6,8-二氨基丁炔硫基衍生物。测试所有这些化合物对人胶质母细胞瘤SNB-19,人腺癌MDA-MB-231和黑素瘤C-32细胞系的抗癌活性。抗癌活性取决于取代基的性质及其在嘌呤和黄嘌呤骨架中的定位。通常,具有两个炔硫基(丙炔硫基或氨基丁炔硫基)的化合物比仅具有一个基团的化合物更具活性。一些化合物显示出与顺铂更强或相似的抗癌活性。还测试了所有化合物对正常人成纤维细胞(HFF-1)的细胞毒活性。发现最有希望的抗癌化合物是2,6-二丙炔基硫基-7-甲基嘌呤
