The dihydropyranoindole scaffold was identified as a promising target for improving the anti-cancer activity of HDAC inhibitors from the preliminary screening of a library of compounds. A suitable methodology has been developed for the preparation of novel dihydropyranoindoles via the Hemetsberger indole synthesis using azido-phenylacrylates, derived from the reaction of corresponding alkynyl-benzaldehydes
从化合物库的初步筛选中,二氢吡喃吲哚支架被确定为提高 HDAC 抑制剂抗癌活性的有希望的目标。已经开发了一种合适的方法,通过 Hemetsberger 吲哚合成使用叠氮苯基丙烯酸酯制备新型二氢吡喃并吲哚,衍生自相应的炔基苯甲醛与叠氮乙酸甲酯的反应,然后在高沸点溶剂中进行热环化。评估了所有新合成化合物对 SH-SY5Y 和 Kelly 神经母细胞瘤细胞以及 MDA-MB-231 和 MCF-7 乳腺癌细胞系的抗癌活性。生物学研究表明,四环系统在较高浓度下对神经母细胞瘤癌细胞具有显着的细胞毒活性。更重要的是,这些系统在较低浓度下显着增强了 SAHA 毒性。除此之外,发现指定系统对健康人体细胞的毒性显着低于癌细胞。
