Unraveling phosphodiesterase surfaces. Identification of phosphodiesterase 7 allosteric modulation cavities

The last findings of our group by using chemical genetic approaches have shown that PDE7 is an interesting target in neurodegenerative diseases. The following step in this travel to unravel PDE7 is the design of more selective inhibitors. In this sense we have proposed to perform an analysis of PDE7 surface to identify possible allosteric sites following by a docking study of different PDE7 inhibitors synthesized by our group. Thanks to these studies we have proved the existence of allosteric sites in PDE7 and we have been able to explain the binding modes of the employed PDE7 inhibitors.
