The mitotic kinesin Eg5 (or KSP) is a crucial player in the development and function of the mitotic spindle. Inhibition of this protein leads to cell cycle arrest and apoptosis without interfering with other microtubule-dependent processes. Therefore, it is a potential target in cancer therapy. Here, we report the synthesis and biological evaluation of a small library of molecules based on the structure of the known Eg5 inhibitor HR22C16. One of these derivatives (compound trans-24) proved to be a potent and specific Eg5 inhibitor.
有丝分裂驱动蛋白Eg5（或KSP）在有丝分裂纺锤体的发育和功能中起着关键作用。抑制这种蛋白质会导致细胞周期停滞和凋亡，而不会干扰其他依赖微管的过程。因此，它是癌症治疗中的一个潜在靶点。在此，我们报告基于已知Eg5抑制剂HR22C16的结构合成并生物学评估了一个小分子文库。这些衍生物之一（化合物反式-24）被证明是一种有效的、特异性的Eg5抑制剂。
