Structure-based design and optimization of 2-aminothiazole-4-carboxamide as a new class of CHK1 inhibitors.
Bioorg.Med.Chem.Lett., 23:2590-2594, 2013

PubMed Abstract: Drug design efforts in the emerging 2-aminothiazole-4-carboxamide class of CHK1 inhibitors have uncovered specific combinations of key substructures within the molecule; resulting in significant improvements in cell-based activity while retaining a greater than one hundred-fold selectivity against CDK2. The X-ray crystal structure of a complex between compound 39 and the CHK1 protein detailing a 'U-shaped' topology and key interactions with the protein surface at the ATP site is also reported.
