introducing lipophilic bicyclic cores in place of the polar pyrazolopyrimidine core of 5-amino-N-(1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamides. Replacement of the pyrazolo[1,5-a]pyrimidine core with the pyrrolo[2,1-f][1,2,4]triazine, the pyrrolo[1,2-b]pyridazine, and thieno[2,3-b]pyrazine cores guided by c Log D led to the identification of highly permeable IRAK4 inhibitors with excellent
IRAK4在IL-1R和TLR信号传导中起关键作用,选择性抑制蛋白激酶活性代表了炎性疾病治疗的诱人靶标。通过引入亲脂性双环核取代5-氨基-N-(1 H-吡唑-4-基)吡唑的极性吡唑并嘧啶核,开发了一系列可渗透的N-(1 H-吡唑-4-基)羧酰胺[ 1,5 - α ]嘧啶-3-羧酰胺。用吡咯并[2,1- f ] [1,2,4]三嗪,吡咯并[1,2- b ]哒嗪和噻吩并[2,3-]取代吡唑并[1,5- a ]嘧啶核b ]由c引导的吡嗪核 Log D导致鉴定出具有出色效能和激酶选择性的高渗透性IRAK4抑制剂。
