- Light-triggered self-assembly of a dichromonyl compound in water
-
External control over self-assembling structures is achieved by incorporating an azobenzene photoswitch into the structure of a dichromonyl compound. The self-assembly of dichromonyl compounds into fibers leads to the formation of a hydrogel and can be triggered with visible light. The Royal Society of Chemistry 2013.

- Design, synthesis, and inhibitory activity of potent, photoswitchable mast cell activation inhibitors
-
Allergic reactions affect millions of people worldwide. The need for new and effective antiallergic agents is evident, and insight into the underlying mechanisms that lead to allergic events is necessary. Herein, we report the design, synthesis, and activity of photoswitchable mast cell activation inhibitors. In mast cell degranulation assays, these inhibitors possess significantly greater potency than an original, chromone-based antiallergic agent. Furthermore, one of the photoswitchable inhibitors shows a significant difference in inhibitory activity between its two photoisomeric forms. Further optimization could ultimately lead to a photoswitchable compound suitable for studying mechanisms involved in allergic reactions in a novel manner, with activity addressable by light and with precise spatiotemporal control over events at the molecular level.
