optimization of a series of pyrrolopyrimidine inhibitors of interleukin-1 receptor associated kinase 4 (IRAK4) using X-ray crystal structures and structure based design to identify and optimize our scaffold. Compound 28 demonstrated a favorable physicochemical and kinase selectivity profile and was identified as a promising in vivo tool with which to explore the role of IRAK4 inhibition in the treatment of mutant
本文中,我们报告了使用X射线晶体结构和基于结构的设计来鉴定和优化我们的支架,优化了一系列白介素1受体相关激酶4(IRAK4)的吡咯并嘧啶抑制剂。化合物28表现出良好的理化和激酶选择性,并被认为是一种有前途的体内工具,可利用该工具探索IRAK4抑制作用在突变MYD88 L265P弥漫性大B细胞淋巴瘤(DLBCL)的治疗中的作用。化合物28已显示在体外高浓度下具有抑制NF-κB活化和ABC亚型ABC亚型生长的能力,但与低浓度下的BTK抑制剂联用则显示出更大的作用。在体内,化合物28和依鲁替尼的组合在ABC-DLBCL小鼠模型中导致肿瘤消退。
