Structural Investigation of the Hedamycin:d(ACCGGT) 2 Complex by NMR and Restrained Molecular Dynamics
Hedamycin, a member of the pluramycin family of drugs, displays a range of biological responses including antitumor and antimicrobial activity. The mechanism of action is via direct interaction with DNA through intercalation between the bases of the oligonucleotide and alkylation of a guanine residue at 5′-PyG-3′ sites. There appears to be some minor structural differences between two earlier studies on the interaction of hedamycin with 5′-PyG-3′ sites. In this study, a high-resolution NMR...[Show more]
