A series of diazonium salts of 4-(N-methyl-N-phenylamino)-3-amino-1,8-naphthalic anhydride 5a, its naphthalimide derivative 5b, and 5e were designed and synthesized,and it was the first time to discover that aromatic radical-induced intramolecular aromatic 1, 5-hydrogen transfer was also involved in the nitrogen-contianed system during Pschorr cyclization.

实验设计合成了4--3-氨基-1，8-萘酐的重氮盐5a、其衍生物N-丁基-4--3-氨基-1，8-萘酰亚胺的重氮盐5b和N--4--3-氨基-1，8-萘酰亚胺的重氮盐5c，并首次发现了通过普朔尔环化反应以氮甲基化的氮为桥原子的体系存在着芳香自由基诱导的芳香1，5-氢转移。

However, accidental changes in DNA methylation can be transmitted through mitosis or meiosis, leading to epiallelic variation.

但是，DNA甲基化的意外变化能够通过有丝分裂或减数分裂，导致表观变异。

Moreover, we could accomplish such silencing in a cancer cell line genetically modified to lack virtually any capacity to methylate DNA.

此外，在经过遗传改变导致无法发生DNA甲基化的癌细胞系中，我们能够成功地再现这一沉默机制。

The metals which are of particular concern are those which have been shown to be methylated in nature.
