To investigate these interactions, we have developed biomimetic competing ligands that are assembled from two Stargazin-derived PSD-95/DLG/ZO-1 (PDZ) domain–binding motifs using ‘click’ chemistry.
Click Chemistry is a new approach to rapidly and selectively react ("click") a pair of functional groups with each other in mild, aqueous conditions. Click Chemistry reactions can be categorized into two separate groups: (1) Cu(I)-catalyzed Azide-Alkyne Click Chemistry reaction (CuAAC); (2) Strain-promoted Azide-Alkyne Click Chemistry reaction (SPAAC).
