Structure-based de novo design and synthesis of aminothiazole-based p38 MAP kinase inhibitors

Bioorg Med Chem Lett. 2015 Sep 15;25(18):3784-7. doi: 10.1016/j.bmcl.2015.07.094. Epub 2015 Aug 5.

Abstract

p38 mitogen-activated protein kinase (MAPK) is a promising target for the development of therapeutics for various immunological diseases. We designed and synthesized aminothiazole-based p38 MAPK inhibitors of with IC50 values ranging from 0.1 to 2 μM by means of the structure-based de novo design of phenyl-(2-phenylamino-thiazol-5-yl)-methanone scaffold. Because these newly identified inhibitors were also screened for having desirable physicochemical properties as a drug candidate, they deserve consideration for further investigation as anti-inflammatory drugs. Structural features relevant to the stabilization of the newly identified inhibitors in the ATP-binding site of p38 MAPK are discussed in detail.

Keywords: Anti-inflammatory drugs; De novo design; Inhibitor; Kinase; p38 MAPK.
