IDENTIFICATION OF NOVEL P38 ALPHA MAP KINASE INHIBITORS USING FRAGMENT-BASED LEAD GENERATION.
Overview
We describe the structure-guided optimization of the molecular fragments, 2-amino-3-benzyloxypyridine 1 (IC(50) 1.3 mM) and, 3-(2-(4-pyridyl)ethyl)indole 2 (IC(50) 35 microM) identified using X-ray, crystallographic screening of p38alpha MAP kinase. Using two separate case, studies, the article focuses on the key compounds synthesized, the, structure-activity relationships and the binding mode observations made, during this optimization process, resulting in two potent lead series that, demonstrate significant increases in activity. We describe the process of, compound elaboration either through the growing out from fragments into, adjacent pockets or through the conjoining of overlapping fragments and, demonstrate that we have exploited the mobile conserved activation loop, consisting in part of Asp168-Phe169-Gly170 (DFG), to generate significant, improvements in potency and kinase selectivity.
