Effect of microwave irradiation on covalent ligand-DNA interactions

Chem Commun (Camb). 2009 May 28:(20):2875-7. doi: 10.1039/b902357g. Epub 2009 Apr 3.

Abstract

A 30 second burst of microwave irradiation at an energy level insufficient to cause DNA denaturation or damage drives the covalent reaction between pyrrolobenzodiazepine (PBD) antitumour agents and double-stranded or hairpin oligonucleotides to completion, a process that normally takes between 3-24 hours and thus offering the opportunity for higher-throughput screening of covalent-binding DNA-interactive agents.
