  名称：

  O-alkylhydroxylamines as rationally-designed mechanism-based inhibitors of indoleamine 2,3-dioxygenase-1

  摘要：

  Indoleamine 2,3-dioxygenase-1 (IDO1) is a promising therapeutic target for the treatment of cancer, chronic viral infections, and other diseases characterized by pathological immune suppression. Recently important advances have been made in understanding IDO1's catalytic mechanism. Although much remains to be discovered, there is strong evidence that the mechanism proceeds through a heme-iron bound alkylperoxy transition or intermediate state. Accordingly, we explored stable structural mimics of the alkylperoxy species and provide evidence that such structures do mimic the alkylperoxy transition or intermediate state. We discovered that O-benzylhydroxylamine, a commercially available compound, is a. potent sub-micromolar inhibitor of IDO1. Structure activity studies of over forty derivatives of O-benzylhydroxylamine led to further improvement in inhibitor potency, particularly with the addition of halogen atoms to the meta position of the aromatic ring. The most potent derivatives and the lead, O-benzylhydroxylamine, have high ligand efficiency values, which are considered an important criterion for successful drug development. Notably, two of the most potent compounds demonstrated nanomolar-level cell-based potency and limited toxicity. The combination of the simplicity of the structures of these compounds and their excellent cellular activity makes them quite attractive for biological exploration of IDO1 function and antitumor therapeutic applications.

  钯(II)催化芳烃的远程元C-H功能化，通过多任务草酰胺作为连接剂实现

  摘要：

  已经建立了使用腈模板作为导向基团在含有草酰胺的芳烃中进行间位-C-H键的钯催化烯化反应。该方法表现出高间位选择性并耐受不同的官能团，例如苄氧基酰胺和烯烃底物。以良好的收率获得了所需的产物。这种方法能够对天然产物和药物进行修饰，并且也适用于克级。此外，通过选择性裂解酰胺键或O-N键，可以轻松去除定向模板，以获得间位官能化的羟胺和苯甲醇。所提出的方法对于新药的设计具有巨大的潜力。

  product PF1022A. In particular an improved efficacy against Haemonchus contortus Rudolphi and Trichostrongylus colubriformis Giles in sheep compared to the potent cyclic octadepsipeptide PF1022A and its mono-thionated derivative has been observed. Here we report on a specific modification at the N-methyl amide linkage by using the mono-thionated PF1022A, resulting in novel anthelmintically active backbone

  The present disclosure relates to a novel vascular leakage inhibitor. The novel vascular leakage inhibitor of the present invention inhibits the apoptosis of vascular endothelial cells, inhibits the formation of actin stress fibers induced by VEGF, and enhances the cortical actin ring structure, thereby inhibiting vascular leakage. Accordingly, the vascular leakage inhibitor of the present invention can prevent or treat various diseases caused by vascular leakage. Since the vascular leakage inhibitor of the present invention is synthesized from commercially available or easily synthesizable pregnenolones, it has remarkably superior feasibility of commercial synthesis.
