Abstract
Polo-like kinase 1 (Plk1), a member of a family of serine/threonine kinases, is an attractive target for the development of anticancer drugs because it is involved in the regulation of cell-cycle progression and cytokinesis. This kinase provides two pockets for developing Plk1 inhibitors: the N-terminal catalytic domain (NCD) and the polo-box domain (PBD). For both of the two pockets, some natural products were identified as Plk1 inhibitors and some synthetic Plk1 inhibitors were developed by mimicking ATP and phosphopeptides, natural products binding to NCD and PBD respectively. This article not only reviews the progression of Plk1 inhibitors binding to these two pockets, but also discusses diversity evolution and jump in the process of drug development using Plk1 inhibitors as examples and how they impact on drug design and pharmacophore modeling.
