โœฆ Synopsis

The interaction of 8-anilino-1-naphthalenesulfonate CANS) with 2,6-di-O-methyl-cyclomaltoheptaose (2,6-DM$CD) was investigated in a 0.1 M phosphate buffer at pH 7.4 by fluorescence spectrophotometry. Utilizing the fact that the fluorescence intensity of ANS increases in the presence of 2,6-DM-PCD, the thermodynamic parameters for inclusion complex formation were determined as follows: AGo= -10.3 kJ.mol-' at 25ยฐC AH"= -13.4 kJ.mol-', As"= -10.9 J.degg'.mol-'.

The main driving force for the inclusion complex formation was considered to be the Van der Waals-London dispersion forces, while the contribution of the hydrophobic interaction was small. Also, from the measurements of proton nuclear magnetic resonance spectra and studies with Corey-Pauling-Koltun models, the probable structure was determined.

The proton magnetic resonance (PMR) and phosphorus magnetic resonance (PhMR) spectra of egg phosphatidylcholine in the presence of l-anilino-8-naphthalenesulfonate (ANS) have been studied. At low ratios of ANS to phospholipid, the spectra indicate that ANS molecules are in the lipid interface region

## Abstract The addition of the fluorescent dye, ANS, to intact ascites tumor cells results in an enhancement of fluorescence intensity. The increase in fluorescence intensity as a function of time is biphasic which suggests that at least two processes occur. The first associated with the rapid ini
