  2-（苯基硒基）乙烷磺酰胺作为苯胺的新型保护基，可通过自由基反应脱保护

  摘要：

  通过2-氯磺酰氯进行磺酰化，然后共轭加入苯硒酚，苯胺被保护为2-（苯基硒代）乙烷磺酰苯胺（SeES苯胺）。在AIBN存在下，使用氢化三丁基锡通过自由基还原将SeES苯胺脱保护。当将氢化物和AIBN缓慢添加到系统中时，可以高收率获得相应的苯胺。由于自由基反应在中性条件下进行，因此实现了SeES基团的化学选择性脱保护。SeES苯胺在各种条件下（包括某些恶劣条件）都稳定。

  Discovery and Structure–Activity Relationship of Potent and Selective Covalent Inhibitors of Transglutaminase 2 for Huntington’s Disease

  摘要：

  Tissue transglutaminase 2 (TG2) is a multifunctional protein primarily known for its calcium-dependent enzymatic protein cross-linking activity via isopeptide bond formation between glutamine and lysine residues. TG2 overexpression and activity have been found to be associated with Huntington's disease (HD); specifically, TG2 is up-regulated in the brains of HD patients and in animal models of the disease. Interestingly, genetic deletion of TG2 in two different HD mouse models, R6/1 and R6/2, results in improved phenotypes including a reduction in neuronal death and prolonged survival. Starting with phenylacrylamide screening hit 7d, we describe the SAR of this series leading to potent and selective TG2 inhibitors. The suitability of the compounds as in vitro tools to elucidate the biology of TG2 was demonstrated through mode of inhibition studies, characterization of druglike properties, and inhibition profiles in a cell lysate assay.

  SeES anilide was deprotected by radical reduction using tributyltin hydride in the presence of AIBN. The corresponding anilines were obtained in high yields when the hydride and AIBN were added to the system slowly. Since the radical reaction proceeds under neutral conditions, chemoselective deprotection of the SeES group was accomplished. The SeES anilide was stable under various conditions, including
