Characterization of Regioisomeric Conjugates Arising from Pixantrone at AP Sites in DNA

Abstract Alkylation at N7 of guanine leads to formation of abasic (AP) sites in DNA. These equilibrate between α and β anomers and form conjugates with 6,9-bis[(2-aminoethyl)amino]benzo[g]isoquinoline-5,10-dione (Pixantrone, PIX). NMR revealed that these conjugates formed as regi...
