A solid phase linker strategy for the direct synthesis of EDANS-labeled peptide substrates. Beythien, Joerg; White, Peter D. (Novabiochem, Merck Biosciences AG, Laufelfingen CH-4448, Switz.). Tetrahedron Letters, Volume Date 2005, 46(1), 101-104 (English) 2004 Elsevier B.V. 275375-42-3 and 50402-56-7 which are cas registry numbers are also used here. CODEN: TELEAY. ISSN: 0040-4039. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) A novel linker strategy for the efficient synthesis of peptides C-terminally labeled with the EDANS [EDANS = 1-Naphthalenesulfonic acid, 5-[(2-aminoethyl)amino]-] fluorophore is described. Using this support, FRET peptide substrates bearing EDANS/Dabcyl [Dabcyl = benzoic acid, 4-[[4-(dimethylamino)phenyl]azo]-] fluorescent donor/acceptor groups can be readily prepd. using std. Fmoc (Fmoc = 9-fluorenylmethyloxycarbonyl) solid phase methods. .

DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) Section cross-reference(s): 73 The authors synthesized anionic hydrogels contg. fluorophores and investigated the adsorption of a cationic quencher having an amino group into hydrogels by fluorescence resonance energy transfer (FRET). FRET from the fluorophore to the quencher in hydrogels was examd. by fluorescence intensity and fluorescence decay using a fluorescence spectrophotometer and femtosecond laser spectroscopy. The fluorescence intensity of the fluorophore-contg. hydrogels decreased rapidly with increasing amts. 914477-52-4 and 50402-56-7 which are cas registry numbers of chemicals are mentioned. of adsorbed cationic quencher. The fluorescence emission of the fluorophore in the quencher-adsorbed hydrogels contg. fluorophores decayed more rapidly than that of the original hydrogels. The aforementioned result indicates that the fluorescence of the fluorophore-contg. hydrogels is quenched due to FRET from the fluorophore to the quencher as the cationic quenchers can approach the fluorophores in hydrogels by electrostatic interactions. .
