Publikováno v: JBIC Journal of Biological Inorganic Chemistry. 3:236-245

The synthesis of cis-Pt(NH3)2(dCMP) is reported and by various physico-chemical methods it is demonstrated that it is a macrochelate in which Pt(II) is bound simultaneously to the N3 site of cytosine in dCMP2– and to a phosphate-oxygen atom. Accord

Coordination of two monoprotonated 2'-deoxyguanosine 5'-monophosphate species, H(dGMP)−, via N7 to cis-(NH3)2Pt2+ gives the complex cis-(NH3)2Pt(H·dGMP)2 which is a four-protonic acid. The corresponding acidity constants were measured by potentiom
