Non-covalent interactions between nucleosides and molecular clips comparison of phosphate, phosphonate and sulphate containing clipsRaditzky, B.
Water-soluble clips are possible molecules to study the weak, non-covalent interactions, responsible for many biological processes. The association between nucleosides and sulphate containing clips, with naphthalene or anthracene sidewalls, has been studied by time-resolved laser-induced fluorescence spectroscopy with ultrafast pulses (fs-TRLFS). The determined association constants for the 1:1 complexes range from log Ka = 3.9 4.2. The measured spectra assumes the appearance of excited state species.
