Starting with 3-amino-2-quinoxalinecarbonitrile 1,4-dioxide 1, a new series of quinoxaline derivatives was prepared through chemical modifications of the 2-cyano and 3-amino groups. Nitration of 3-amino-2-quin-oxalinecarbonitrile 3 afforded the 7-nitro derivative 6. Diazotation of 3 gave the 3-chloro compound 9. 2,3-Quinoxalinedicarbonitrile 14 was obtained from 9. Pyridazino[4,5-b]quinoxalines 15 and 16
从3-氨基-2-喹喔啉腈1,4-二氧化物1开始,通过化学修饰2-氰基和3-氨基制备了一系列新的喹喔啉衍生物。硝化3-氨基-2-喹喔啉腈3,得到7-硝基衍生物6。3的重氮化得到3-氯化合物9。从9获得2,3-喹喔啉二甲腈14。吡啶并[4,5- b ]喹喔啉15和16是通过将14与水合肼缩合而制备的。三唑并[4,5- b ]喹喔啉18,鉴定出异噻唑并[4,5- b ]喹喔啉20和两个吡唑并[3,4- b ]喹喔啉21和22。测试了化合物在有氧和低氧细胞中的细胞毒性作用。
