Synthesis of Photoreactive Phosphatidic Acid Analogues Displaying Activatory Properties on Cyclic AMP-phosphodiesterases. Photoaffinity Labeling of an Isoform of Phosphodiesterase
photoactivatable phosphatidicacidanalogues 1-azidoPA (12) and 2-azidoPA (7 and 15), potentially suitable for covalent labeling of PDE4, have been synthesized. The ability of phospholipases A(2) and D to hydrolyze unnatural phospholipids has been considered in this paper. The effect of 1-azidoPA (12) and 2-azidoPA (7 and 15) on the activity of a recombinant PA-sensitive isoform PDE4D3 was evaluated
