以4-氨基苯甲酸为原料, 经重氮化反应后与甲基烷基胺反应构建三氮烯骨架, 随后将羧基与2-二乙基氨基乙氨缩合, 合成了11个1-(4-(N-(2-二乙氨基)乙基)氨甲酰基)苯基-3-甲基-3-烷基(R2)三氮烯化合物1-(4-(N-(2-二乙氨基)乙基)氨甲酰基)-3-甲基-3-环己基三氮烯(6a)~1-(4-(N-(2-二乙氨基)乙基)氨甲酰基)-3-甲基-3-(4-硝基)苄基三氮烯(6k), 3步反应的总收率为46.5%~68.3%. 噻唑蓝(MTT)比色法检测发现, 6a、1-(4-(N-(2-二乙氨基)乙基)氨甲酰基)-3-甲基-3-苯基三氮烯(6e)~1-(4-(N-(2-二乙氨基)乙基)氨甲酰基)-3-甲基-3-(4-甲氧基)苄基三氮烯(6j)对人肝癌细胞(HepG-2)、大鼠胶质瘤细胞(C6)、人结肠癌细胞(SW620)、人前列腺癌细胞(PC-3)、小鼠黑色素瘤细胞(B16)和人非小细胞肺癌细胞(A549)共六株肿瘤细胞都有良好的抗肿瘤活性, 显示出广谱的抗癌特性; 其中, 1-(4-(N-(2-二乙氨基)乙基)氨甲酰基)-3-甲基-3-(4-氯)苯基三氮烯(6g)的抗癌活性最为突出, 对C6、SW620、PC-3和B16的IC50值均小于10 μmol/L, 抗癌活性远优于阳性对照药达卡巴嗪. 研究发现, 当R2为具有适当吸电子效应的芳基时, 化合物的抗癌活性较高. 药物安全性评价发现, 6e6g、1-(4-(N-(2-二乙氨基)乙基)氨甲酰基)-3-甲基-3-(4-氯)苄基三氮烯(6h)对C6、SW620、PC-3, 6g~1-(4-(N-(2-二乙氨基)乙基)氨甲酰基)-3-甲基-3-(4-甲氧基)苯基三氮烯(6i)对B16, 6e6h6i对HepG-2, 6i对C6、SW620, 其安全指数(SI)均大于2.0, 其安全性高于达卡巴嗪. 化合物6e6g~6i的油水分布系数(lg P)为3.0~4.0, 具有较高的膜渗透性. 所有数据证实, 新型三氮烯化合物6e6g~6i具有更佳的成药性.

Eleven novel 1-(4-(N-(2-diethylamino)ethyl)aminoformoxyl)phenyl-3-methyl-3-alkyl (R2) triazenes have been designed and synthesized. Firstly, 4-aminobenzoic acid, as starting material, underwent diazo reaction following the reaction with methyl alkylamine to build the triazene scaffold. Condensation of carboxylic group with 2-diethylaminoethylamine resulted in all the title compounds. The overall yield of these 3-step reactions was between 46.5% and 68.3%. By using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, 1-(4-(N-(2-diethylamino)ethyl)aminoformoxyl)phenyl- 3-methyl-3-cyclohexyltriazene (6a), 1-(4-(N-(2-diethylamino)ethyl)aminoformoxyl)phenyl-3-methyl-3-phenyltriazene (6e)~1-(4-(N-(2-diethylamino)ethyl)aminoformoxyl)phenyl-3-methyl-3-(4-methoxyl)benzyltriazene (6j) were confirmed as good broad-spectrum anti-cancer agents again/st human liver cancer cells (HepG-2), rat glioma cells (C6), human colon cancer cells (SW620), human prostate cancer cells (PC-3), murine melanoma cells (B16), and human non-small-cell lung cancer cells (A549). Among them, 1-(4-(N-(2-diethylamino)ethyl)aminoformoxyl)phenyl-3-methyl-3-(4-chloro)phenyltriazene (6g) show- ed as the most active agent, where IC50 values of 6g against C6, SW620, PC-3, and B16 cell lines are less than 10 μmol/L, which is far better than the positive dacarbazine. It was found that when R2 is aryl group with propriate electron-withdrawal intensity, the triazene will have good even excellent anti-cancer activity. Through drug safety evaluation, the safety indexes (SI) of 6e, 6g, and 1-(4-(N-(2-diethylamino)ethyl)aminoformoxyl)phenyl-3-methyl-3-(4-chloro)benzyltriazene (6h) against C6, SW620, and PC-3 cell lines, respectively; 6g, 6h, and 1-(4-(N-(2-diethylamino)ethyl)aminoformoxyl)phenyl-3-methyl-3-(4- methoxyl)phenyltriazene (6i) against B16 cell line respectively; 6e, 6h, and 6i against HepG-2 cell line respectively; 6i against C6, and SW620 cell lines, respectively; were identified more than 2.0, implied better drug safety than dacarbazine. The partition coefficient (lg P) of 6e, 6g~6i lied between 3.0 and 4.0, meaning good membrane permeability. All the data support that the novel triazenes 6e, 6g~6i have better druggability.
