appropriate 1,2- and 1,3-diamines. Some of the 11-(ω-aminoalkylamino) derivatives were further transformed into 11-ureido and thioureido analogues. Many of the prepared neocryptolepine derivatives showed submicromolar antiproliferative activity against the human leukemia MV4-11 cell line. Among them, 11-(3-amino-2-hydroxy)propylamino derivatives 2h and 2k were the most cytotoxic with a mean IC50 value of 0
新隐油菜碱是一种四环吲哚喹啉生物碱,对拓扑异构酶II具有抑制作用,并具有抗增殖活性。本研究描述了几种新的隐烯平类似物的合成和抗增殖评价,这些类似物在C11处带有分支的功能化的二元侧链。这些2-取代的5-甲基-吲哚并[2,3-b]喹啉衍生物是通过用适当的1,2-和1,3-二胺对11-氯新隐油菜碱进行亲核芳香取代(SNAr)来制备的。一些11-(ω-氨基烷基氨基)衍生物进一步转化为11-脲基和硫脲基类似物。制备的许多新隐肾上腺素衍生物对人白血病MV4-11细胞系表现出亚微摩尔的抗增殖活性。他们之中,
