  肿瘤进展基因2（Tpl2）激酶和肿瘤坏死因子α（TNF-α）产生的抑制剂：新型8取代4-苯胺基6-氨基喹啉3-腈的选择性和体内抗炎活性。

  摘要：

  肿瘤进展基因座2（Tpl2）（Cot / MAP3K8）是MAP3K家族中位于MEK上游的丝氨酸/苏氨酸激酶。最近使用Tpl2敲除小鼠的研究表明Tpl2在脂多糖（LPS）诱导的肿瘤坏死因子α（TNF-alpha）和其他与风湿性关节炎等疾病有关的促炎细胞因子的产生中具有重要作用。最初的4-苯胺基-6-氨基喹啉-3-甲腈导线显示出对Tpl2的选择性较表皮生长因子受体（EGFR）激酶差。使用和不使用EGFR激酶特异性4-苯胺基喹唑啉抑制剂（erlotinib，Tarceva）的EGFR激酶结构域的分子模型和晶体学数据，我们假设我们可以通过在C-8位置进行取代来减少对EGFR激酶的抑制作用4-苯胺基-6-氨基喹啉-3-腈引线。由适当的2-取代的4-硝基苯胺制备8-取代的4-苯胺基-6-氨基喹啉-3-甲腈。对C-6和C-8位置的修饰导致鉴定了对LPS刺激的大鼠和人类血液中TNF-α释放抑制作用增强的

  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.
