Abstract
ESI mass spectrometry was used to assess the ability of metal complexes to inhibit binding of a transcription factor to a DNA molecule containing its recognition sequence. ESI-MS showed that both [Ru(phen)₂(dppz)]²⁺ and [Pt(5,6-Me₂phen)(S,S-dach)] ²⁺ can interfere with binding of the transcription factor PU.1-DBD to a dsDNA molecule containing its consensus binding site. This further highlights the potential of metal complexes as drug leads for transcription therapy, and the potential role that ESI-MS may play as a rapid screening tool in drug development.
