Diprotonated cyclo[n]pyrroles represent a set of expanded porphyrin analogues with structures similar to that of telomestatin, a natural product known to bind to and stabilize G-quadruplexes, and it is inferred that external stacking represents the dominant binding mode for the interaction of cyclo(n)pyrrole with d(T(2)AG(3))(4).

author keywords: ion mobility; G-quadruplexes; DNA
TL;DR:
To determine if G-quadruplexes are present in a solvent-free environment, different lengths of the telomeric repeat d(T2AG3)n and dTG4T were investigated with mass spectrometry, ion mobility and molecular dynamics calculations.
