A novel series of antiproliferative agents containing pyrazolo[1,5-a]pyrimidin-7-yl phenyl amides, selective for p21-deficient cells, were identified by high-throughput screening. Exploration of the SAR relationships in the headpiece, core, and tailpiece is described. Strict steric, positional, and electronic requirements were observed, with a clear preference for both core nitrogens, a thienoyl headpiece, and meta substituted tailpiece. (c) 2007 Elsevier Ltd.
