the synthesis and antiproliferative evaluation of certain 11-aminoalkylamino-substituted 5H- and 6H-indolo[2,3-b]quinolines and their methylated derivatives. These 5-Me- and 6-Me-indolo[2,3-b]quinoline derivatives 10–14, 20 were prepared by amination at the C-11 position of the 11-chloro-5-methyl-5H- and 11-chloro-6-methyl-6H-indolo[2,3-b]quinolines with different substituents on the quinoline ring
本报告描述了某些11-氨基烷基氨基取代的5 H-和6 H-吲哚并[2,3- b ]喹啉及其甲基化衍生物的合成和抗增殖评价。这些5-ME-和6-ME-吲哚并[2,3- b ]喹啉衍生物10 - 14,20是由胺化在11氯-5-甲基-5-的C-11位置制备ħ -和11在喹啉环上具有不同取代基的-氯-6-甲基-6 H-吲哚并[2,3- b ]喹啉。在11 aminoalkylaminomethylated 23,的同系物11从相同的中间体制备了,用于进一步的SAR研究。这些中间体可从4-取代的苯胺或其N-甲基化的类似物和吲哚-3-羧酸甲酯作为对应物获得。体外抗增殖试验表明,5-甲基化衍生物10-14比其各自的6-甲基化6 H-吲哚并[2,3- b ]喹啉衍生物20具有更高的细胞毒性。其中,N-(3-氨基丙基)-2-溴-5-甲基-5 H-吲哚并[2,3 - b ]喹啉-11-胺12f具有最大的细胞毒性,平均IC
