Synthesis and reactivity of novel γ-phosphate modified ATP analogues

We hereby present a simple yet novel chemical synthesis of a family of γ-modified ATPs bearing functional groups on the γ-phosphate that are amenable to further derivatization by highly selective chemical manipulations (e.g., click chemistry, Staudinger ligations). A preliminary screen of these compounds as phosphate donors with a typical wild type protein kinase (cdk2) and one of its known substrates p27kip1 is also presented.
