tert-butyl moiety at the 5-position of imidazole was essential for the activity of such compounds. Immunofluorescence assay indicated that compounds 17o and 17p could efficiently inhibit microtubule polymerization. Overall, the novel furan-diketopiperazine-type derivatives could be considered as a potential scaffold for the development of anti-cancer drugs.
海洋生物天然产物“ diketopiperazine phenylahistin”的合成类似物Plinabulin对微管具有解聚作用,并靶向秋水仙碱位点,秋水仙碱位点已进入III期临床试验,用于治疗非小细胞肺癌(NSCLC)和非小细胞肺癌。预防化疗引起的中性粒细胞减少症(CIN)。为了开发更有效的抗微管和细胞毒性衍生物,总结并分析了纤连蛋白衍生物的共晶体复合物。我们对咪唑型衍生物的叔丁基部分或C环进行了进一步修饰,以通过引入不同骨架的新型骨架建立分子库。我们的结构活性关系研究表明,化合物17o(IC50 = 14.0 nM,NCI-H460)和17p(IC50 = 2.9 nM,具有呋喃基团的NCI-H460)在纳摩尔水平上针对各种人类癌细胞系表现出强力的细胞毒活性。特别是呋喃基团的5-甲基或甲氧基甲基取代基可以取代咪唑在5位上的烷基以维持细胞毒活性,这与以前的报道相反,咪唑5位上的叔丁基
