Popis: In the quest for novel allosteric inhibitors of the p38 MAP kinase, we recently described the A-loop regulatory site, identified through molecular modeling studies together with the disclosure of a small molecule hit with a moderate inhibitory profile. Starting from this structure, we subsequently identified two additional hits with simpler molecular structures from an in silico screening study, using a substructure search in the SciFinder database. After corroboration of their inhibitory profile, analysis of their structures permitted to conclude about the suitability of the [1,2,5]oxadiazolo[3,4-b]pyrazine (furazano[3,4-b]pyrazine) scaffold for the development of potent A-loop regulatory site p38 MAP kinase inhibitors. Accordingly, we report the synthesis and pharmacological evaluation of a series of di-substituted analogs with a potent inhibitory profile of p38 MAP kinase, as shown by in vitro assays of their capability to inhibit IL-1β secretion in human monocyte-derived macrophages.
