چکیده

8-Azidoadenosine 3',5'-cyclic monophosphate (8-azido cAMP) was directly detected in living cells, by applying Cu-free azide-alkyne cycloaddition to probe cAMP derivatives by fluorescence light-up. Fluorescence emission was generated by two non-fluorescent molecules, 8-azido cAMP as a model target and difluorinated cyclooctyne (DIFO) reagent as a probe. The azide-alkyne cycloaddition reaction between 8-azido cAMP and DIFO induces fluorescence in 8-azido cAMP. The fluorescence emission serves as a way to probe 8-azido cAMP in cells.

Three-Component and Click Strategy for Synthesis of β-Hydroxy 1,4-Disubstituted 1,2,3-Triazoles Derivatives Catalyzed by 1,4-Dihydroxyanthraquinone-copper(II) Complex onto Nano AlPO4

In this work, copper(II) heterogeneous nanocatalyst supported on modified AlPO4 (Cu(II)-DA@Nano AlPO4) was used for the synthesis of some biological active heterocyclic molecules, particularly for the efficient conversion of a wide range of non-activated terminal alkynes to β-hydroxy 1,4-disubstituted 1,2,3-triazolethrough a three-component “click” reaction at room temperature in water. The reg...

Three Component Syntheses of Pyrrolo Imidazole Derivatives in the Presence of N-methyl imidazole, Activated Acetylenes and Phenylsulfonylacetophenone

Because of the significant role in biological processes in living cells and the diverse types of physiological activities, heterocyclic compounds are in focus of intense investigations by academic, industry and applied-oriented chemists. Considerably, ascientific renaissance of heterocycles during the last decades is closely related to the development of multicomponent approaches to their s...

ANTICALMODULIN DRUGS DUE TO THE NET EFFECTS CANNOT ANTAGONIZE DIBUTYRYL-CAMP-MEDIATED SUPPRESSION OF DE NOVO SYNTHESIZED LIPID SECRETION IN BOTH CULTURED MCARDLE CELLS AND RAT HEPATOCYTES

The effects and interaction between cAMP-analogue dibutyryl-cAMP and calmodulin antagonists were investigated on de novo synthesis and secretion of lipids in cultures of hepatoma McArdle-RH7777 cells and normal rat hepatocytes. Dibutyryl cAMP caused a significant decrease in the secretion of de novo synthesized triacyl [3H] glycerol in both cultures of McArdle cells and rat hepatocytes. The ...
