This disclosure provides novel hydrogels that can undergo multiple gel-sol transitions and methods of making and using such hydrogels, particularly in anastomosis procedures. The peptide hydrogels comprising a fibrillar network of peptides that are in an amphiphilic β-hairpin conformation. The peptides comprise photo-caged glutamate residues with a neutral photocage that can be photolytically selectively uncaged to disrupt the fibrillar network and trigger an irreversible gel- sol phase transition of the hydrogel. Isolated peptides for making the disclosed hydrogels are provided, as are methods of using the peptide hydrogels in anastomosis procedures.
A class of photo-caged and cell permeable fluorescent molecules having high uncaging cross sections, robust fluorescence enhancement, and flexible chemistry for bioconjugation. Some of the photo-caged fluorescent molecules are derived from 6-chloro-7-hydroxy-coumarin 3-carboxamide. The fluorescent molecules are useful for cellular imaging applications and particularly for tracing the molecular transfer between cellular gap junctions. The fluorescent molecules also have an emission wavelength that spectrally complements with the emission wavelength of other fluorophores, enabling simultaneous multi-color imaging.
Photolysis of a Caged, Fast-Equilibrating Glutamate Receptor Antagonist, MNI-Caged γ-D-Glutamyl-Glycine, to Investigate Transmitter Dynamics and Receptor Properties at Glutamatergic Synapses
Fast uncaging of low affinity competitive receptorantagonists can in principle measure the timing and concentration dependence of transmitter action at receptors during synaptic transmission. Here, we describe the development, synthesis and characterization of MNI-caged γ-D-glutamyl-glycine (γ-DGG), which combines the fast photolysis and hydrolytic stability of nitroindoline cages with the well-characterized
