-yl)-1H-benzo[de]isoquinoline-1,3(2H)-dione, referred to as ZSM02 (9a), whose structure was further confirmed by X-ray crystallography. The structure showed a remarkable coplanarity between the N-acetyltriazene and the naphtalimide moiety. Thus, we unequivocally assigned 9a as the product of the reaction and compared its growth inhibitory activity with that of its precursor, EG22. ZSM02 exhibited identical
6-(3-甲基三唑-1-烯-1-基)-1H-苯并[去]异喹啉-1,3(2H)-二酮,称为EG22(8a),为开链3-烷基-1被称为“复合分子”的2,3-三氮烯被设计用来抑制聚(二磷酸腺苷核糖)聚合酶(PARP)并破坏DNA。为了延迟其水解,需要N3的乙酰化。作为单烷基1,2,3-三氮烯,EG22可能在溶液中呈两个互变异构体,或在反应过程中损失氮,从而导致几种乙酰化的化合物。取而代之的是,观察到一种化合物并明确指定其结构,我们在其制备过程中引入了同位素标记的试剂,目的是在N2处引入15N并在3-甲基中引入13C。结果表明,由15N-NMR证实,1,2,3-三氮烯部分保持完整,15N标记的N2和13C标记的甲基之间的偶联模式。此外,我们进行了异核单量子相干(HSQC)和异核多键相关性(HMBC)实验,该实验允许检测和分配6-(3-乙酰-3-甲基三甲基三氮-1-烯-1-基)中的所有四个氮原子。 -1H-苯并[异]喹啉-1
