Anaplastic Large Cell Lymphoma (ALCL) is an aggressive T-cell lymphoma affecting children and young adults. About 30% of patients develop therapy resistance therefore new precision medicine drugs are highly warranted. Multiple rounds of structure-activity optimization of Caffeic Acid Phenethyl Ester have resulted in CM14. CM14 causes upregulation of genes involved in oxidative stress response and downregulation of DNA replication genes leading to G2/M arrest and subsequent apoptosis induction. In accordance with this, an unbiased proteomics approach, confocal microscopy and molecular modeling showed that TUBGCP2, member of the centrosomal γ-TuRC complex, is a direct interaction partner of CM14. CM14 overcomes ALK inhibitor resistance in ALCL and is also active in T-cell Acute Lymphoblastic Leukemia and Acute Myeloid Leukemia. Interestingly, CM14 also induced cell death in docetaxel-resistant prostate cancer cells thus suggesting an unexpected role in solid cancers. Thus, we synthesized and thoroughly characterized a novel TUBGCP2 targeting drug that is active in ALCL but has also potential for other malignancies.
间变性大细胞淋巴瘤(ALCL)是一种侵袭性T细胞淋巴瘤,影响儿童和年轻人。约30%的患者会产生治疗耐药性,因此非常需要新的精准药物。对咖啡酸苯乙酯进行多轮构效优化后得到了CM14。CM14导致参与氧化应激反应的基因上调,DNA复制基因下调,导致G2/M期阻滞并随后诱导凋亡。据此,一种无偏向蛋白质组学方法、共聚焦显微镜和分子建模表明,中心体γ-TuRC复合体成员TUBGCP2是CM14的直接相互作用伙伴。CM14克服了ALCL中ALK抑制剂的耐药性,在T细胞急性淋巴细胞白血病和急性髓系白血病中也有活性。有趣的是,CM14还能诱导多西他赛耐药前列腺癌细胞死亡,因此提示其在实体癌中具有意想不到的作用。因此,我们合成并全面表征了一种新型的靶向TUBGCP2的药物,该药物对ALCL有活性,但对其他恶性肿瘤也有潜在作用。
