Stereodifferentiation in fluorescence quenching within cholic acid aggregates.
نویسندگان
چکیده
Two cholic acid (ChA) analogues, containing a 4-nitrobenzo-2-oxa-1,3-diazole (NBD) moiety at C-3, were incorporated into ChA aggregates and submitted to fluorescence quenching by the two enantiomers of several tryptophan derivatives. In all cases, a significant stereodifferentiation was observed; the most remarkable effect was found when comparing the 3alpha and the 3beta diastereomers.

Two-channel dansyl/tryptophan emitters with a cholic acid bridge as reporters for local hydrophobicity within supramolecular systems based on bile salts.
The aim of the present work is to develop two-channel emitters to probe local hydrophobicity by means of fluorescence quenching within different biomimetic supramolecular environments. To achieve this goal, the dansyl (Dns) and tryptophan (Trp) fluorophores have been covalently attached to cholic acid (CA) in order to ensure simultaneous incorporation of the two emitting units into the same com...
متن کاملFluorescence properties of pyrene derivative aggregates formed in polymer matrix depending on concentration.
We investigated the fluorescence properties of dye aggregates formed in a poly(vinylalcohol) (PVA) matrix by phase separation. Trimethyl-(2-oxo-2-pyrene-1-yl-ethyl)-ammonium bromide (PyAm) was used as a fluorescent dye molecule. The size of PyAm aggregates in the PVA thin films were increased with increasing dye concentration, which was confirmed by atomic force microscope (AFM) measurements. T...
متن کاملA cholic acid-based fluorescent chemosenor for the detection of ATP.
A novel ditopic cholic acid-based fluorescent chemosensor for ATP, 1a, was designed and synthesized. Its interactions with phosphates, AMP, ADP, ATP, CTP, GTP, and TTP have been investigated. When ATP was added to a 1:1 aqueous CH3CN solution of the sensor at pH 7.4, a significant decrease in fluorescence of 1a was observed, whereas other guest molecules showed a much smaller effect. The comple...

1872 CLINICAL CHEMISTRY, Vol. 29, No. 10, 1983 we measure serum total bile acids by the 3HSD-diaphorase method, using the “Sterognost 3a Flu” kit (Nyeg#{228}rd, Oslo, Norway), 50 L of serum + 1200 L of Tris HCI buffer (0.1 moUL, pH 9.0) + 250 L of Sterognost solution. Table 1 shows the effect of protein with and without pre-heating the sample. The “calculated cholic acid concentration” refers t...

Water-soluble fluorescent probes, including 1-pyrene butyric acid, rhodamine B, sodium salt 1,5diaminoanthraquinone-2,6-disulfonic acid, quinine hemisulfate and monosodium salt 8-amino1-naphthol-3,6-disulfonic acid were used to determine the critical micelle concentration (cmc) of inverted micelles formed by cholic acid in tetrahydrofuran. Another water-insoluble fluorescent probe, namely pyren...
