  Property- and Structure-Guided Discovery of a Tetrahydroindazole Series of Interleukin-2 Inducible T-Cell Kinase Inhibitors

  摘要：

  Interleukin-2 inducible T-cell kinase (ITK), a member of the Tec family of tyrosine kinases, plays a major role in T-cell signaling downstream of the T-cell receptor (TCR), and considerable efforts have been directed toward discovery of ITK-selective inhibitors as potential treatments of inflammatory disorders such as asthma. Using a previously disclosed indazole series of inhibitors as a starting point, and using X-ray crystallography and solubility forecast index (SFI) as guides, we evolved a series of tetrahydroindazole inhibitors with improved potency, selectivity, and pharmaceutical properties. Highlights include identification of a selectivity pocket above the ligand plane, and identification of appropriate lipophilic substituents to occupy this space. This effort culminated in identification of a potent and selective ITK inhibitor (GNE-9822) with good ADME properties in preclinical species.

• Highly Regioselective Organocatalyzed Synthesis of Pyrazoles from Diazoacetates and Carbonyl Compounds

  β‐ketoesters, β‐diketones, and aldehydes), as well as the operational simplicity of this process, a convenient, practical, and highly modular pyrazole synthesis has been developed. We believe that this work will arouse more research interest in the organocatalytic synthesis of other biologically active heterocycles. Such studies are currently underway in our laboratory.

  已经开发了一系列羰基化合物与重氮乙酸酯之间的一般有机催化逆电子需求[3 + 2]环加成反应。该反应被仲胺作为“绿色促进剂”催化，以生成具有高区域选择性的取代吡唑。值得注意的是，这种[3 + 2]环加成反应在室温下使用简单且廉价的催化剂即可有效地进行。考虑到起始原料（例如酮，β-酮酸酯，β-二酮和醛）的多样性和现成的可用性，以及该方法的操作简便性，已开发了一种方便，实用且高度模块化的吡唑合成方法。我们相信这项工作将在其他生物活性杂环的有机催化合成中引起更多的研究兴趣。
