A series of some new tetrahydroindolocarbazole derivatives has been synthesized. The structure of the synthesized compounds has been confirmed by different spectroscopic techniques such as IR, NMR, elemental analysis and mass spectrometry. The target compounds were evaluated for their antitumor activity against breast cancer cell line MCF-7, their GI% and their LC50 have been determined. Six of the
已经合成了一系列新的四氢吲哚并咔唑衍生物。合成的化合物的结构已通过不同的光谱技术(例如IR,NMR,元素分析和质谱法)确认。评估了目标化合物对乳腺癌细胞系MCF-7的抗肿瘤活性,确定了其GI%和LC 50。六个合成的化合物对MCF-7细胞系的GI%值超过70%,在71.9%至85.0%之间,此外化合物11的GI%值为99.9%,被认为是合成衍生物中活性最高的衍生物。化合物11 与DOX相比,u PA水平显着降低至3.5 ng / ml。化合物5,11和15显示出在MTAP和CDKN2A的表达显著减少,除了在DNA损伤彗星试验方法的显着降低。进行了分子建模研究,以解释活性配体作为uPA抑制剂的行为。
