  Synthesis of new acylsulfamoyl benzoxaboroles as potent inhibitors of HCV NS3 protease

  摘要：

  HCV NS3/4A serine protease is essential for the replication of the HCV virus and has been a clinically validated target. A series of HCV NS3/4A protease inhibitors containing a novel acylsulfamoyl benzoxaborole moiety at the P1 ' region was synthesized and evaluated. The resulting P1-P3 and P2-P4 macrocyclic inhibitors exhibited sub-nanomolar potency in the enzymatic assay and low nanomolar activity in the cell-based replicon assay. The in vivo PK evaluations of selected compounds are also described. (C) 2010 Elsevier Ltd. All rights reserved.

  靶向丝裂原活化蛋白激酶激酶 4 (MKK4) 的 1H-吡唑并[3,4-b]吡啶的设计和合成——肝再生的一个有希望的靶点

  摘要：

  目前，治疗肝功能衰竭的治疗选择非常有限。由于最近通过体内RNAi 实验发现丝裂原活化蛋白激酶激酶 4 (MKK4)是肝细胞再生的主要调节因子，因此我们致力于开发一种针对该蛋白激酶的小分子。从已获批的 BRAF V600E抑制剂 vemurafenib ( 8 )开始，该抑制剂在初始筛选中显示出对 MKK4 的高脱靶亲和力，我们采用了支架跳跃方法，将核心杂环从 1 H -吡咯 [2,3- b ]吡啶到 1 H-吡唑并[2,3- b ]吡啶（10）。对 MKK4 的亲和力可以得到保留，而对脱靶蛋白激酶的选择性略有提高。进一步的修改导致58和59在低纳摩尔范围内显示出对 MKK4 的高亲和力，以及来自必需抗靶点（MKK7、JNK1）和脱靶点（BRAF、MAP4K5、ZAK）的强制性多参数优化的优异选择性。 MKK4 通路。在此我们报告了此类中的第一个选择性 MKK4 抑制剂。

  The invention relates to pyrazolo-pyridine compounds which inhibit mitogen-activated protein kinase kinase 4 (MKK4) and in particular, selectively inhibit MKK4 over protein kinases JNK1 and MKK7. The compounds are useful for promoting liver regeneration or reducing or preventing hepatocyte death. They are further useful for treating osteoarthritis or rheumatoid arthritis, or CNS-related diseases.
