Four potent CK2 inhibitors derived from CX-4945 are described. They also provided nanomolar activity against HDAC1, therefore having promising utility as dual-target agents for cancer. The linker length between the hydroxamic acid and the CX-4945 scaffold plays an important role in dictating balanced activity against the targeted enzymes. The seven-carbon linker (compound ) was optimal for inhibition of both CK2 and HDAC1. Remarkably, showed 3.0 and 3.5 times higher inhibitory activity than the reference compounds CX-4945 (against CK2) and SAHA (against HDAC1), respectively. Compound exhibited micromolar activity in cell-based cytotoxic assays against multiple cell lines.
描述了四种源自CX-4945的强效CK2抑制剂。它们对HDAC1也具有纳摩尔活性,因此作为癌症的双靶点药物具有广阔的应用前景。异羟肟酸与CX-4945支架之间的连接子长度在决定对靶向酶的平衡活性方面起着重要作用。七碳连接子(化合物 )对于抑制CK2和HDAC1是最佳的。值得注意的是, 分别显示出比参考化合物CX-4945(针对CK2)和SAHA(针对HDAC1)高3.0倍和3.5倍的抑制活性。化合物 在针对多种细胞系的基于细胞的细胞毒性试验中表现出微摩尔活性。
