Design, synthesis, and evaluation of non-ATP-competitive small-molecule polo-like kinase 1 (Plk1) inhibitors

, p. 2 - 9 (2015)
A series of small-molecule Plk1 inhibitors targeting the substrate-binding pocket were designed through rational drug design for the first time. The designed compounds were synthesized and their activities were evaluated in vitro. Some of the targeted compounds showed potent Plk1 inhibitory activities and anti-proliferative characters. Particularly, 5i showed Plk1 inhibitory activity with an IC50 value of 0.68 μM. Compound 5i also showed cell growth inhibitory activity on HeLa cells with an IC50 value of 0.51 μM, which is about four times more potent compared to thymoquinone. The mechanism of action suggested that 5i was an ATP-independent and substrate-dependent Plk1 inhibitor. Compound 5i demonstrated excellent Plk1 inhibitory selectivity against Plk2, Plk3, and five serine/threonine and tyrosine kinases. Our discovery and structure-activity relationship study may provide useful lead compounds for further optimization of non-ATP-competitive Plk1 inhibitors.

Radical cyclisation onto imidazoles and benzimidazoles
Aldabbagh, Fawaz,Bowman, W. Russell
, p. 4109 - 4122 (2007/10/03)
New synthetic methodology has been developed for the synthesis of [1,2- a]fused imidazoles and benzimidazoles using intramolecular homolytic aromatic substitution. In the intramolecular substitution, N-(ω-alkyl) radicals are generated using Bu3SnH from N-(ω-phenylselanyl)alkyl side chains. Phenylselanyl groups are used as radical leaving groups to avoid problems in the N-alkylation of imidazoles and benzimidazoles. Arylsulfones for imidazoles, and phenylsulfides for benzimidazoles, are used at the leaving groups in the homolytic substitutions.
