基于已知的MNK1/2激酶(mapk相互作用激酶)抑制剂合成了两种新的含二茂铁化合物。这些化合物被设计成利用二茂铁的独特形状来利用MNK1/2中仅部分被原始化合物占据的大疏水口袋。二茂铁类似物的筛选表明,尽管MNK的效力丧失,但两者在几种乳腺癌和AML(急性髓性白血病)细胞系中都表现出强有力的抗癌作用。在体外进一步分析MDA-MB-231(三阴性乳腺癌细胞)中最有效的二茂铁化合物5。化合物5在2D和3D的剂量-反应曲线上产生的IC50值(最大半数抑制浓度)分别为0.55µM和1.25µM。
Two novel ferrocene-containing compounds based upon a known MNK1/2 kinase (MAPK-interacting kinase) inhibitor have been synthesized. The compounds were designed to use the unique shape of ferrocene to exploit a large hydrophobic pocket in MNK1/2 that is only partially occupied by the original compound. Screening of the ferrocene analogues showed that both exhibited potent anticancer effects in several breast cancer and AML (acute myeloid leukemia) cell lines, despite a loss of MNK potency. The most potent ferrocene-based compound 5 was further analysed in vitro in MDA-MB-231 (triple negative breast cancer cells). Dose–response curves of compound 5 for 2D assay and 3D assay generated IC50 values (half maximal inhibitory concentration) of 0.55 µM and 1.25 µM, respectively.
