WebApr 11, 2024 · Photocaging of peptides can be achieved by the attachment of a photocaging molecule at a side-chain functionality, backbone amide, or at the C-or N-terminus of the peptide. Recently, we reported the optical control of orexin-B using a UV-visible light-sensitive C-terminal photocage (Duffet et al., 2024b). WebWe report a new strategy, viz. cascade photocaging, for protecting diethylamine diazeniumdiolate (O2-position), a light sensitive molecule. Upon photolysis, the cascade photocage at first releases the light activatable linker (latent fluorophore) O2-caged diazeniumdiolate, which undergoes spontaneous 1,8-eli

WebNov 24, 2024 · To this end, a team led by Andrea Rentmeister chose to use a method known as photocaging. In this method, a “photocage” is a molecule that falls apart upon irradiation, such as a 2-nitrobenzyl group. The cage first blocks the target location, then targeted irradiation with light acts as a “switch” to remove the blockade.
