Abstract
6,7-Dimethyllumazine more selectively binds to adenine (A) base opposite the abasic site in DNA duplexes (5′-TCC AGX GCA AC-3′/3′-AGG TCN CGT TG-5′, X = AP site (Spacer C3), N = A, T, C and G) than the other three nucleobases with a dissociation constant Kd of ca. 1.0 μM; substituted methyl groups enhance the binding affinity to A and the selectivity for A over T, compared to the parent molecule, lumazine.
