โœฆ Synopsis


The interaction specificities of Co(III) with DNA were investigated via consideration of thermodynamic characteristics of the duplex to single strand transition for DNA oligomers incubated in the presence of [Co(NH 3 ) 5 (OH 2 )](ClO 4 ) 3 . It has previously been demonstrated that incubation of the DNA oligomer [(5medC-dG) 4 ] 2 with this cobalt complex leads to coordination of the cobalt center to the DNA, presumably at N7 of guanine bases [D.
