摘要

通过在腺嘌呤环的 C-2 处引入未经测试的取代基，探索了氟化酶（EC 2.5.1.63）对底物的耐受性。最有活性的类似物是 N-烷基化胺，作为一个类别，它们比 O-或 S-醚好得多。这些结果都得到了硅学分析的支持。这种耐受性拓宽了氟化酶的用途，可将氟-18 同位素引入正电子发射断层扫描应用的配体中。

Exploring Fluorinase Substrate Tolerance at C-2 of SAM.

The substrate tolerance of the fluorinase enzyme (EC 2.5.1.63) is explored by introducing untested substituents at C-2 of the adenine ring. The most active analogues were N-alkylated amines and as a class these were much better than O- or S- ethers. The outcomes are supported by in silico analysis. This tolerance broadens the utility of the fluorinase as a tool for introducing the fluorine-18 isotope into ligands for positron emission tomography applications.
