Abstract excerpt
The interaction of newly synthesised water-soluble planar complexes of general structure [Pt(diimine)(N,N-dihydroxyethyl-N'-benzoylthioureato)]+Cl- with DNA was investigated by means of DNA melting studies, CD spectroscopy, and DNA gel mobility studies. Addition of stoichometric amounts of [Pt(diimine)H2L-S,O]Cl complexes to polynucleotides caused a significant increase in the melting temperature of poly(dA-dT)...
