neocryptolepine core, the 5-Me-indolo[2,3-b]quinoline skeleton, was emblazoned with substituents at C11 and C2 and then tested against various cancer cell lines to find potent anticancer agents. In the in vitro antiproliferative activity assay against the breast cancer MDA-MB-453 cell line, the attachment of alkylamino substituents at C11 of the 5-Me-indolo[2,3-b]quinoline induced improved activities. Specifically
摘要植物来源的新隐油菜籽芯5-Me-吲哚并[2,3- b ]喹啉骨架在C11和C2处被取代基修饰,然后针对各种癌细胞系进行测试,以找到有效的抗癌剂。在针对乳腺癌MDA-MB-453细胞系的体外抗增殖活性测定中,在5-Me-吲哚并[2,3- b ]喹啉的C11处连接烷基氨基取代基可诱导活性提高。具体而言,11-(3-氨基丙基氨基)和11-(4-氨基丁基氨基)衍生物对MDA-MB-453(IC 50 = 0.3–0.5μM),并且对结肠腺癌(WiDr)和卵巢癌(SKOv3)细胞系表现出更高的细胞毒性。对于给电子基团,例如CH 3 O,有利地观察到通过取代基在C2处的结合产生的协同作用,而对于诸如F和CF 3的吸电子基团,则不利地观察到。套索在C11处的末端游离氨基进一步修饰成相应的酰基酰胺和2,3-二氢苯并[e] [1,3]噻嗪-4-酮对抗增殖活性无效。计算机辅助数据库分析COMPARE表明,
