well as N6-hydroxyagelasine analogs were synthesized by selective N-7 alkylation of N6-[tert-butyl(dimethyl)silyloxy]-9-methyl-9H-purin-6-amine in order to install the terpenoid side chain, followed by fluoride mediated removal of the TBDMS-protecting group. N6-Hydroxyagelasine D and the analog carrying a geranylgeranyl side chain displayed profound antimicrobial activities against several pathogenic
通过对N6- [叔丁基(二甲基)甲硅烷氧基]进行选择性N-7烷基化反应,合成了(+)-N6-羟基芥子油D,(-)-己糖肟D拟议结构的对映体以及N6-羟基芥子油类似物。 -9-甲基-9H-嘌呤-6-胺,以安装萜类侧链,然后氟化物介导的TBDMS保护基的去除。N6-羟基芥子油D和带有香叶基香叶基侧链的类似物显示出对几种病原菌和原生动物的深层抗菌活性,并抑制了细菌生物膜的形成。但是这些化合物对哺乳动物的成纤维细胞(MRC-5)也有毒性。N6-羟基尿嘧啶D的光谱数据与以前报道的Ageloxime D的光谱数据不匹配。因此,提出了一种改型的阿糖肟肟D的结构。
