  名称：

  Thiazolo[5,4-f]quinazolin-9-ones, inhibitors of glycogen synthase kinase-3

  摘要：

  In an effort to identify new protein kinase inhibitors with increased potency and selectivity, we have developed the microwave-assisted synthesis of thiazolo[5,4-f]quinazolin-9-ones. The effects of eighteen derivatives on CDK1/cyclin B, CDK5/p25, and GSK-3 were investigated. Several turned out to inhibit GSK-3 in the micromolar range. Molecular modeling studies suggest that the most selective GSK-3 inhibitors 7a-d bind into the ATP-binding site through a key hydrogen bond interaction with Val135 and target the specific hydrophobic backpocket of the enzyme.

  Continuous efforts in microwave-assisted synthesis and the structure-activity relationships' (SARs) studies of novel modified 9-oxo-thiazolo[5,4-f]quinazoline-2-carbonitriles, allowed identification of new amidine and imidate derivatives as potent and dual CDK1/GSK-3 inhibitors. Combination of lead optimization and molecular modeling studies allowed identification of a dual CDK1/GSK-3 inhibitor (compound 13d) with submicromolar values. (c) 2007 Elsevier Masson SAS.
