  A series of 2,6,9-trisubstituted purine derivatives have been synthesized and investigated for their potential role as antitumor agents. Twelve compounds were obtained by a three step synthetic procedure using microwave irradiation in a pivotal step. All compounds were evaluated in vitro to determine their potential effect on cell toxicity by the MTT method and flow cytometry analysis on four cancer cells lines and Vero cells. Three out of twelve compounds were found to be promising agents compared to a known and effective anticancer drug, etoposide, in three out of four cancer cell lines assayed with considerable selectivity. Preliminary flow cytometry data suggests that compounds mentioned above induce apoptosis on these cells. The main structural requirements for their activity for each cancer cell line were characterized with a preliminary pharmacophore model, which identified aromatic centers, hydrogen acceptor/donor center and a hydrophobic area. These features were consistent with the cytotoxic activity of the assayed compounds.

  合成并研究了一系列2,6,9-三取代嘌呤衍生物，以探讨其作为抗肿瘤剂的潜在作用。通过三步合成程序获得了十二个化合物，其中微波辐射在一个关键步骤中发挥了重要作用。所有化合物都进行了体外评估，以确定其对细胞毒性的潜在影响，使用MTT法和流式细胞术分析四种癌细胞系和Vero细胞。与已知的有效抗癌药物依托泊苷相比，十二个化合物中有三个在四种癌细胞系中显示出良好的选择性，具有潜在的应用前景。初步的流式细胞术数据显示，上述化合物能诱导这些细胞的凋亡。每种癌细胞系的活性主要结构要求通过初步药效团模型进行了表征，该模型确定了芳香中心、氢受体/供体中心和疏水区域。这些特征与所测试化合物的细胞毒性活性一致。

  Prolinamide organocatalysts with aminouracils have the features of enhanced NH acidity, an additional hydrogen‐bond donor and the self‐assembly with complementary modules by Watson–Crick pairing. Each module affects the selectivity of the reaction and particularly 2,6‐diaminopyridine is beneficial to the selectivity in the reaction.
