  1,2,4-Triazolo[4,3-a]quinoxaline-1,4-diones as antiallergic agents

  摘要：

  A series of new 1,4-dihydro-1,2,4-triazolo[4,3-]quinoxaline-1,4-diones has been prepared. These compounds were tested as inhibitors of antigen-induced release of histamine (AIR) in vitro from rat peritoneal mast cells (RMC) and as inhibitors of IgE-mediated rat passive cutaneous anaphylaxis (PCA). Most of this new class of antiallergic agents showed good activity in the RMC and PCA tests. The most potent compound, 2-acetyl-7-chloro-5-n-propyl-1,2,4-triazolo[4,3-a]quinoxaline-1,4-dione (1x), with an I50 value of 0.1 microM, is 30 times more potent than disodium cromoglycate (DSCG) in the RMC assay.

• Visible-Light-Induced Recyclable g-C3N4 Catalyzed C–H Hydroxylation of Quinoxalin-2(1H)-ones

  A visible-light-promoted hydroxylation of quinoxalin-2(1H)-ones using recyclable graphitic carbon nitride (g-C3N4) as a heterogeneous photocatalyst has been developed. This protocol enables the selective synthesis of various hydroxyl-containing quinoxalin-2(1H)-ones in good to excellent yields under an ambient air atmosphere. Importantly, this heterogeneous catalyst can be used at least six times without significant loss of activity.

  摘要：本文报道了一种可回收的石墨烯碳氮化物（g-C3N4）作为异相光催化剂，促进喹诺啉-2（1H）-酮的可见光催化羟基化反应。该方法在常温常压空气下，能够高选择性地合成各种含羟基的喹诺啉-2（1H）-酮产物，产率良好至优良。重要的是，该异相催化剂可以重复使用至少六次而不会显著降低活性。

  A practical protocol for the preparation of quinoxaline‐2,3(1H,4H)‐diones through direct C(sp2)−H hydroxylation of quinoxalin‐2(1H)‐ones in recyclable DL‐α‐Tocopherol methoxypolyethylene glycol succinate solution (2 wt% in water) (TPGS‐750‐M/H2O) was developed. The target products were exclusively generated and could be collected through extraction and recrystallization.
