7-氨基-6-硝基-[1，2，5]噁二唑并[3，4-b]吡啶-1-氧化物（1）与胺在温和条件下反应，氧化呋咱环开环，释放一分子次硝酸，得到了蓝绿色的开环产物2-胺取代的-3-亚硝基-4-氨基-5-硝基吡啶5a~5f.发现化合物1中的6-位硝基对其氧化呋咱开环起到关键作用.利用1H NMR，13C NMR和HRMS对目标化合物进行了结构表征.用四甲基偶氮唑盐（MTT）法测试了目标化合物体外抑制人肺癌细胞株（H522）和脑胶质瘤细胞株（U87）两种肿瘤细胞的增殖活性.测试结果显示，所有目标化合物均表现较强的体外肿瘤细胞抑制活性.

Reaction of 7-amino-6-nitro[1,2,5]oxadiazolo[3,4-b]pyridine-1-oxide (1, namely pyridofuroxan) with ammonia or/and amines under mild conditions let to the corresponding 5-nitro-3-nitroso-2,4-diaminopyridine 5a~5f. It is shown that the ring-opening reactivity of pyridofuroxan 1 was significantly affected by the 6-nitro substituent. The structures of all target compounds were identified by 1H NMR, 13C NMR and HRMS. The biological evaluation was performed on human lung cancer cell line (H522) and glioma cell line (U87) by 3-(4,5-dimethylthigal-2-yl)-2,5-(diphenyltetragalium) bromide (MTT) assay. The results suggested that all of the target compounds exhibited potent anti-tumor activities in vitro.
