A series of new 6,9-disubstituted purine analogs with 4-substituted piperazine at C-6 and 4-substituted benzyl at N-9 were designed and synthesized in four steps. All synthesized compounds ( 7 – 26 ) were screened initially for their in vitro anticancer activity on Huh7 liver, HCT116 colon and MCF7 breast carcinoma cell lines. Cytotoxic bioactivity studies revealed that all compounds screened, with
设计并在四个步骤中合成了一系列新的6,9-二取代嘌呤类似物,它们在C-6处具有4-取代的哌嗪,在N-9处具有4-取代的苄基。最初筛选了所有合成的化合物(7–26)对Huh7肝癌,HCT116结肠癌和MCF7乳腺癌细胞系的体外抗癌活性。细胞毒性生物活性研究表明,除化合物19外,所有被筛选的化合物均对IC癌细胞Huh7,HCT116和MCF7的IC 50范围为0.05–21.8μM,具有有希望的细胞毒活性。在制备的嘌呤类似物中,其中两个(12和22)对Huh7细胞表现出优异的细胞毒性活性,IC 50为0.08-0.13μM,可与喜树碱(CPT)媲美,且优于克拉屈滨,氟达拉滨和5-FU。然后,针对最有效的嘌呤类似物的细胞毒性评估针对进一步的肝细胞癌(HCC)细胞系进行了筛选。6-(4-(4-三氟甲基苯基)哌嗪(12)和6-(4-(3,4-二氯苯基)哌嗪类似物(25)与HCC细胞(Huh7和Hep
