Cytosine Derivatives Form Hemiprotonated Dimers in Solution and the Gas Phase
摘要:
Hemiprotonated dimers of cytosine derivatives, implicated in the formation of the i-motif of DNA, have been created in solution and the gas phase. The mechanism of dimerization has been analyzed by mass spectrometry and multidimensional NMR spectroscopy.

masses of E2Zn2W2 (dimeric Zn-CDA with two water molecules), E2Zn2W2Fz, and E2Zn2W2Fz2, where Fz represents the 3,4-hydrate of 5-fluorozebularine. In the absence of an inhibitor, E2Zn2 is the only dimeric species detected, with no additional water molecules. Experiments conducted in H218O indicate that the added mass W represents a trapped water molecule rather than an isobaric ammonium ion. This appears
