DNA alkylation promoted by an electron-rich quinone methide intermediate

Chengyun Huang,Steven E. Rokita

Frontiers of Chemical Science and Engineering 2016, Volume 10, Issue 2,   Pages 213-221 doi: 10.1007/s11705-015-1541-3

Abstract: methides have previously been limited by the slow exchange of their covalent self-adducts and subsequent alkylationprecursor and a 5'-aminohexyloligonucleotide accelerates formation of its reversible self-adduct and alkylationof its complementary DNA as predicted from prior model studies.
