Fluorescent Sensing of Triphosphate Nucleotides via Anthracene Derivatives
摘要:
A nucleotide is composed of a nucleobase, a five-carbon sugar, and phosphate groups. Recognition of these three sites can provide useful information for the development of selective fluorescent receptors for a specific nucleotide. In this paper, anthracene derivatives with two imidazolium groups at the 1,8- and 9,10-positions, quaternary ammonium groups, or the boronic acid group were examined for the recognition of nucleotides, such as ATP, GTP, CTP, TTP, UTP, ADP, and AMP, via fluorescence changes. The anthracene group provides the interaction between the bases of the nucleotides. The imidazolium and quaternary ammonium groups induce hydrogen bonding interactions with the phosphate groups of the nucleotides. The boronic acid group can interact with the ribose of the nucleotides.

Two new anthracene thiourea derivatives, 1 and 2, were investigated as fluorescentchemosensors for the chiralrecognition of the twoenantiomers of α-amino carboxylates. Especially, host 2 displayed Kl/Kd values as high as 10.4 with t-Boc alanine. Furthermore, the d/l selectivity of hosts 1 and 2 is opposite, even though both hosts bear the same glucopyranosyl units. These intriguing opposite d/l
