Abstact

The structure-based design, synthesis, and anticancer activity of novel inhibitors of protein kinase CK2 are described. Using pyrazolo[1,5-a][1,3,5]triazine as the core scaffold, a structure-guided series of modifications provided pM inhibitors with microM-level cytotoxic activity in cell-based assays with prostate and colon cancer cell lines.
