  Fluorophore-Labeled S-Nitrosothiols

  摘要：

  A series of fluorophore-labeled S-nitrosothiols were synthesized, and their fluorescence enhancements upon removal of the nitroso (NO) group were evaluated either by transnitrosation or by photolysis. It was shown that, with a suitable alkyl linker, the fluorescence intensity of dansyl-labeled S-nitrosothiols could be enhanced up to 30-fold. The observed fluorescence enhancement was attributed to the intramolecular energy transfer from fluorophore to the SNO moiety. Ab initio density functional theory (DFT) calculations indicated that the "overlap" between the SNO moiety and the dansyl ring is favored because of their stabilizing interaction, which was in turn affected by both the length of the alkyl linker and the rigidity of the sulfonamide unit. In addition, one of the dansyl-labeled S-nitrosothiols was used to explore the kinetics of S-nitrosothiol/thiol transnitrosation and was evaluated as a fluorescence probe of S-nitrosothiol-bound NO transfer in human umbilical vein endothelial cells.

  Making a radical change! Radical CC bond formation by thermal carboaminoxylation of alkoxyamines was used for functionalization of unsaturated macromolecular systems with biologically important residues (R; see scheme). The synthesized dendritic mannose‐containing glycopolymers show very strong inhibition of the lectin Concanavalin A as measured by an enzyme‐linked lectin assay.
