Abstract

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 3α and the 3β diastereomers.
