p38 MAP kinase inhibitors. Part 6: 2-arylpyridazin-3-ones as templates for inhibitor design.

p38 inhibitors based on 3,4-dihydropyrido[4,3-d]pyrimidazin-2-one template were synthesized and their SAR explored. Benchmark compounds 30, 35, and 36 were found to be potent against the enzyme. Crystal structure of p38 in complex with 30 indicated a key pi-stacking interaction with the pendant tyrosine residue-35 in the glycine-rich loop.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB codes are shown on the right.
