Description HI-TOPK-032 is an effective and specific inhibitor of TOPK.
In vitro HI-TOPK-032通过降低ERK-RSK磷酸化以及通过调节p53、裂解的caspase-7和裂解的PARP的含量增加结肠癌细胞凋亡,从而抑制锚定依赖和锚定独立的结肠癌细胞生长。然而,在最高浓度(5 μM)时,HI-TOPK-032还能将MEK1活性抑制40%。HI-TOPK-032强烈抑制TOPK激酶活性,但对细胞外信号调节激酶1(ERK1)、c-jun-NH2激酶1或p38激酶活性影响较小。HI-TOPK-032占据TOPK的ATP结合位点,并非常适合该结合位点。该化合物与GLY83和ASP151形成氢键,并与LYS30发生疏水作用。
In vivo HI-TOPK-032(1或10 mg/kg;小鼠)治疗明显抑制了HCT-116肿瘤生长,相对于对照组抑制率超过60%。小鼠对HI-TOPK-032治疗耐受良好。
