title: The discovery of novel protein kinase inhibitors by using fragment-based high-throughput x-ray crystallography.
abstract: This article describes the application of a high-throughput X-ray crystallographic fragment-based screening methodology to identify low-molecular-weight leads for structure-based optimisation into protein kinase inhibitors. The identification of two novel p38alpha MAP kinase inhibitors (with IC50=65 and 150 nM) starting from low-molecular-weight fragments is described.
