  描述：

  6-(2,4-difluorophenoxy)-8-ethyl-2-methylsulfonyl-8H-pyrido[2,3-d]pyrimidin-7-one 在 盐酸 作用下， 以 N-甲基吡咯烷酮 、 甲醇 、 乙醚 为溶剂， 反应 2.0h， 生成 6-(2,4-difluorophenoxy)-8-ethyl-2-(tetrahydro-2H-pyran-4-ylamino)pyrido[2,3-d]pyrimidin-7(8H)-one hydrochloride

  Discovery of 6-(2,4-Difluorophenoxy)-2-[3-hydroxy-1-(2-hydroxyethyl)propylamino]-8-methyl-8H-pyrido[2,3-d]pyrimidin-7-one (Pamapimod) and 6-(2,4-Difluorophenoxy)-8-methyl-2-(tetrahydro-2H-pyran-4-ylamino)pyrido[2,3-d]pyrimidin-7(8H)-one (R1487) as Orally Bioavailable and Highly Selective Inhibitors of p38α Mitogen-Activated Protein Kinase

  摘要：

  The development of a new series of p38 alpha inhibitors resulted in the identification of two clinical candidates, one of which was advanced into a phase 2 clinical study for rheumatoid arthritis. The original lead, an lck inhibitor that also potently inhibited p38a, was a screening hit from our kinase inhibitor library. This manuscript describes the optimization of the lead to p38-selective examples with good pharmacokinetic properties.
