| Abstract: | The synthesis of 3′-O-{3-N-(4-azido-2-nitrophenyl) amino] propionyl} 8-azido-adenosine 5′-triphosphate—a 3′-arylazido-8-azido ATP—is described. The ATP derivative is characterized by thin layer chromatography, infrared spectroscopy, and optical spectroscopy. Its photolysis upon irradiation with uv light and its stability in dependence on pH are tested. Its two photolabile azido groups allow the use of this ATP analog as a photoaffinity label for cross-linking the subunits of ATP binding proteins. |
