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.

A series of 3-anilino-quinoxalinones has been identified as a new class of glycogen phosphorylase inhibitors. The lead compound I was identified through high throughput screening as well as through pharmacophore-based electronic screening. Modifications were made to the scaffold of 1 to produce novel analogues, some of which are 25 times more potent than the lead compound. (c) 2005 Elsevier Ltd. All rights reserved.
