(1) is scheduled for phase III clinical trials as a vascular disrupting agent. However, its biochemical receptor(s) have yet to be identified. In this report, the synthesis of azido analogues of 1 that could be used for photoaffinity labeling of proteins as an approach toward identifying its molecular targets is described. While 5-azidoxanthenone-4-acetic acid (2) and 5-azido-6-methylxantheone-4-acetic
5,6-二甲基黄嘌呤酮-4-乙酸(1)计划作为血管分裂剂进入III期临床试验。但是,尚未确定其生化受体。在此报告中,描述了1叠氮基类似物的合成,该合成可用于蛋白质的光亲和标记,作为鉴定其分子靶标的方法。虽然发现5-叠氮杂蒽酮-4-乙酸(2)和5-叠氮杂6-甲基methyl吨酮-4-乙酸(3)的生物活性与1,6-叠氮杂-5-甲基x吨酮-4-的生物活性相似。乙酸(4)不稳定,无法评估。叠氮基化合物2和3均激活了NF-κB,在培养的小鼠脾细胞中诱导了肿瘤坏死因子的产生,并在小鼠中诱导了结肠38肿瘤的出血性坏死。
