Abstract

The design, synthesis, and spectroscopic and chemical properties of four members of a new class of heterobifunctional photocleavable (caged) cross-linking reagents were described. One of the two reactive groups of the cross-linker reacted with amine groups to form the corresponding photolabile carbamates. Amino group containing compounds or proteins caged with these reagents can be coupled through the thiol reactive oxirane group of the cross-linker to a different biomolecule or to a thiolderivatized surface. The 3,4-dimethoxy-6-nitrophenyl photoisomerization group of the reagent was physically and chemically isolated from the cross-linking functionality, and the high extinction coefficient and red-shifted action spectrum of this chromophore make it suitable for photoactivation applications of caged compounds on surfaces or in living cells. The bifunctional, photocleavable crosslinking reagents were used to prepare a thiol reactive caged rhodamine 110. The new reagents and conjugation procedures described may be used as part of a general procedure to cage the activity of proteins by physically masking binding sites.
