A series of 3-[α-(acylamino)acyl]-1-aryl-3-methyltriazenes 6a–l, potential cytotoxic triazene prodrugs, were synthesised by coupling 1-aryl-3-methyltriazenes to N-acylamino acids. Their hydrolysis was studied in isotonic pH 7.4 phosphate buffer and in human plasma, while hydrolysis of the derivative 6a was studied in more depth across a range of pH values. Prodrugs 6a–l hydrolyse by cleavage of the
通过将1-芳基-3-甲基三氮烯与N-酰基氨基酸偶联,合成了一系列3- [α-(酰基氨基)酰基] -1-芳基-3-甲基三氮烯6a - 1,潜在的细胞毒性三氮烯前药。在等渗pH 7.4磷酸盐缓冲液和人血浆中研究了它们的水解,而在一系列pH值范围内更深入地研究了衍生物6a的水解。前药6a – l通过裂解三氮烯酰基水解得到相应的单甲基三氮烯。在人体血浆中的研究表明,氨基酸载体的α-氨基的酰化是降低α-氨基酰基衍生物的化学反应性同时保持快速酶水解速率的有效手段。这些衍生物显示出log P值,表明它们应该被生物膜很好地吸收。
