Determining the molecular basis for the pH-dependent interaction between 2′-deoxynucleotides and 9H-pyrido[3,4-b]indole in its ground and electronic excited states
Interaction between norharmane and three different 2′-deoxynucleotides (dNMP) (2′-deoxyguanosine 5′-monophosphate (dGMP), 2′-deoxyadenosine 5′-monophosphate (dAMP) and 2′-deoxycytidine 5′-monophosphate (dCMP)), in aqueous solution, was studied in the ground state by means of UV-vis and 1H-NMR spectr...
