have focused on developing analogues with more desirable physicochemical profiles. Here, we investigated the structure–activity relationship (SAR) of meisoindigo with respect to its antiproliferative activity on leukemic K562 cells and found that appending a phenalkyl side chain onto the lactam NH resulted in analogues that retained good activity. Furthermore, analogues in which the phenyl ring was
Meisoindigo一直用作靛红素的替代品,用于治疗慢性粒细胞白血病(CML)已有数年之久。鉴于其较差的溶解度和不稳定的吸收,一些研究集中在开发具有更理想的理化特性的类似物。在这里,我们研究了美isoindigo对白血病K562细胞的抗增殖活性的结构-活性关系(SAR),发现将苯烷基侧链附加在内酰胺NH上可产生保留良好活性的类似物。此外,苯环被碱性杂环取代的类似物在保持可接受的抗增殖特性的同时,其溶解性明显高于meisoindigo。最有前途的类似物(E)-1-(2-(4-甲基哌嗪-1-基)乙基)-[3,3'-联吲哚基亚基] -2,2'-二酮(5-4)在整个恶性细胞中比meisoindigo更有效,其溶解度至少是meisoindigo的40倍,几乎没有或没有在溶液中聚集的趋势,并且能够显着延长使用K562诱导的异种移植物的动物的寿命。从机制上讲,它诱导凋亡细胞死亡并破坏K562细胞从G 1到G
