The synthesis, cytotoxic activities and selectivities of 35 derivatives related to quinazoline and pyrido[2,3-d]pyrimidine are described. The synthesized compounds were screened in vitro against four tumoral cell lines – leukemia (CCRF-CEM), colon (HT-29), lung (HTB-54) and breast (MCF-7) – and two cell lines derived from non-malignant cell lines, one mammary (184B5) and one from bronchial epithelium
描述了与喹唑啉和吡啶并[2,3- d ]嘧啶有关的35种衍生物的合成,细胞毒活性和选择性。体外针对四种肿瘤细胞系(白血病(CCRF-CEM),结肠(HT-29),肺(HTB-54)和乳腺癌(MCF-7))和两种源自非恶性肿瘤的细胞系筛选了合成的化合物细胞系,一种是乳腺(184B5),另一种是支气管上皮细胞(BEAS-2B)。MCF-7和HTB-54是最敏感的细胞系,其中11种和10种化合物的GI 50值分别低于10μM。鉴定出两种化合物(2o和3a)在所有测试的细胞系中均引起明显的细胞毒性作用,而一种化合物7h对MCF-7具有强效和选择性。对有效衍生物2o,3a和7h的机理的初步研究表明,这些化合物的细胞毒性活性可能是通过诱导细胞死亡而不影响细胞周期阶段来介导的。
