  Imidazo[1,5-d][1,2,4]triazines as potential antiasthma agents

  摘要：

  By using inhibition of histamine release from antigen-challenged, sensitized human basophils as a means of identifying a potentially prophylactic drug for the treatment of asthma, a series of substituted imidazo[1,5-d][1,2,4]triazines were found, which were active. These compounds were prepared by treating imidazolecarboxaldehydes with excess Grignard agent and then oxidizing the resulting alcohols to ketones with Jones reagent. Pyrolysis of a mixture of ketone and methyl carbazate at 200 degrees C in diphenyl ether produced the desired imidazo[1,5-d][1,2,4]triazines. Those compounds with the greatest basophil activity were tested for in vivo activity in the mouse passive cutaneous anaphylaxis (PCA) and the guinea pig passive anaphylaxis tests. The best compounds, 1-ethyl-8-methyl-6-propylimidazo[1,5-d][1,2,4]triazin-4(3H)- one (4-17) and 1,8-dimethyl-6-propylimidazo[1,5-d][1,2,4]triazin-4-(3H)-one (4-16) were chosen for further study.
