  • Title: Identification of acylthiourea derivatives as potent Plk1 PBD inhibitors.
    Author: Yun T, Qin T, Liu Y, Lai L.
    Journal: Eur J Med Chem; 2016 Nov 29; 124():229-236. PubMed ID: 27592392.
    Abstract:
    Thiourea derivatives have drawn much attention for their latent capacities of biological activities. In this study, we designed acylthiourea compounds as polo-like kinase 1 (Plk1) polo-box domain (PBD) inhibitors. A series of acylthiourea derivatives without pan assay interference structure (PAINS) were synthesized. Four compounds with halogen substituents exhibited binding affinities to Plk1 PBD in low micromole range. The most potent compound (3v) showed selectivity over other subtypes of Plk PBDs and inhibited the kinase activity of full-length Plk1.
