Abstract
Aided by molecular modeling, compounds with a pyrimidine-based tricyclic scaffold were designed and confirmed to inhibit Wee1 kinase. Structure-activity studies identified key pharmacophores at the aminoaryl and halo-benzene regions responsible for binding affinity with sub-nM K i values. The potent inhibitors demonstrated sub-μM activities in both functional and mechanism-based cellular assays and also possessed desirable pharmacokinetic profiles. The lead molecule, 31, showed oral efficacy in potentiating the antiproliferative activity of irinotecan, a cytotoxic agent, in a NCI-H1299 mouse xenograft model.Entities:
