particular cell line, CNS SNB-75 cell line, but (5b) exhibited the highest growth inhibitory activity against CNS-SNB-75 cell line with (GI% = 108.81) and (IC50 = 3.703 ± 0.2) compared to erlotinib; (IC50 = 12.5 ± 0.68). It caused Pre-G1 apoptosis and growth arrest at S phase. It also increased percentage of the total apoptotic cells in CNS-SNB-75 cell line (39.26%) compared to control cells (2.17%)
脑肿瘤是顽固的癌症,预后差,存活率令人失望。迫切需要具有更高疗效和更低耐药性的靶向癌症治疗药物。通过将 1-aryl-5-cyano-1,6-dihydro-4-methyl-6-oxo-3-pyridazine-carboxylate 与肉桂腈衍生物的环加成反应,开发了一种高效的多官能化酞嗪衍生物的一锅法合成方法。噻吩并[3,4- d ]哒嗪在受控微波加热下具有高产率的活化双键或三键系统。合成的酞嗪类化合物(5a-e、9和13 )通过体外试验测试了它们的体外抗癌活性。美国国家癌症研究所的一次剂量测定。只有酞嗪(5b ) 对来自所有子组的大多数测试癌细胞系显示出广谱抗肿瘤活性,平均 % GI = 22.61。有趣的是,所有测试的化合物都对特定细胞系 CNS SNB-75 细胞系表现出不同的生长抑制活性,但 ( 5b ) 对 CNS-SNB-75 细胞系表现出最高的生长抑制活性 (GI% =
