kinase inhibitors resulting in several compounds entering clinical development and two FDA approved NMEs. However, despite significant effort during the past 2 decades, identification of highly selective JAK3 inhibitors has eluded the scientific community. A significant effort within our research organization has resulted in the identification of the first orally active JAK3 specific inhibitor, which
致力于发现JAK激酶抑制剂的重要工作导致了几种化合物进入临床开发阶段,以及两个FDA批准的NME。然而,尽管在过去的20年中付出了巨大的努力,但高度选择性的JAK3抑制剂的鉴定仍未引起科学界的重视。我们研究机构的一项重大工作已导致鉴定出第一种口服活性JAK3特异性抑制剂,该抑制剂通过与独特的JAK3残基Cys-909共价相互作用而达到JAK同工型特异性。JAK3酶的相对较快的再合成速率在设计具有适当药效学性质以及有限的不需要的脱靶反应性的共价抑制剂时,提出了独特的挑战。经过努力,确定了11个(PF-06651600)是一种有效的低清除率化合物,具有体内功效。此JAK3特异性抑制剂11的良好疗效和安全性导致了其在多项人类临床研究中的评估。
