Rhodamine based colorimetric and fluorescent probe for recognition of nucleoside polyphosphates through multi-hydrogen bond
A novelty rhodamine B based chemosensor containing 2-amino-7-methyl-1,8-naphthyridine moiety was designed and synthesized for colorimetric and fluorescent response on corresponding nucleoside polyphosphates through multi-hydrogen bond interaction in aqueous solution. The supramolecular recognition between the RBS and Cytidine-5′-diphosphate disodium hydrate (CDP) was investigated carefully: H-1 nuclear magnetic resonance confirmed that the formation of multi-hydrogen bonds between naphthyridine moiety and the nucleoside base group could untie the spiro structure of RBS, and the ESI-MS spectra proved the formation of the 1:1 complexation species between RBS and CDP. The strong emission response of the RBS toward COP and Adenosine-5′-triphosphate disodium trihydrate (ATP) ensures its application in living cells imaging. (C) 2013 Elsevier Ltd. All rights reserved.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 99-55-8. COA of Formula: 152.1506.
