New approaches for the discovery of photopharmacological agents.

Photoswitchable compounds, which can be reversibly switched between two isomers by light, continue to attract significant attention for a wide array of applications that capitalise on the high temporal and spatial precision of using light as a stimulus. The recently established field of photopharmacology1 uses photoswitchable ligands that are selective for a specific cellular target, such as a receptor or an enzyme, and are employed as therapeutic entities. These ligands undergo a change in shape, flexibility, or electronic properties upon irradiation with light that leads to a change in the affinity for their cellular target; therefore, they exhibit a light-dependent therapeutic activity.

This talk will give an overview of our recent discovery of a new class of photoswitch, the azopyrazoles2-4, which offer quantitative photoswitching and high thermal stability of the Z isomer (half-lives of up to ∼1000 days). It will then describe how these switches, together with related heteroaromatic switch designs can enable the discovery of next generation photopharmacological agents, both in terms of target-based design5,6 and new discovery methodologies.
