Formulários:
in vitro AMPylation of proteins^[1,2]
in vitro polyadenylation of RNA^[3]
The resulting alkyne-functionalized protein^[1,2] or RNA^[3] can subsequently be processed via Cu(I)-catalyzed (azide-alkyne) click chemistry that offers the choice

• to introduce a Biotin group for subsequent purification tasks (via Azides of Biotin)
• to introduce fluorescent group for subsequent microscopic imaging (via Azides of fluorescent dyes)
• to crosslink the RNA to azide-functionalized biomolecules e.g.proteins

Presolski et al.^[4] and Hong et al.^[5] provide a general protocol for Cu(I)-catalyzed click chemistry reactions that may be used as a starting point for the set up and optimization of individual assays.
Agonistic ligand, mainly for nucleoside receptor A₁
Nucleoside-triphosphates can be converted by different membrane-bound phosphatases into nucleosides acting as nucleoside receptor ligands. In some cases nucleoside phosphates act also directly on nucleoside receptors.

Please note: This compound contains a phosphoramide linkage which is hydrolyzed at pH
