Abstract
The molecular hydrogen complex of osmium, [trans-en(2)Os(eta-H-2)](2+) (en, entlylendediamine) is a new H-1 NMR recognition probe for biomole cules. By using this probe, the coordination between deoxyguanylic aci d (dGMP) and four metal anticancer complexes, titanocene dichloride, ( C2H5)(2)SnCl2(phen), (C2H5)(2)SnCl2 and cisplatin are studied in D2O u nder the condition near the physiological one. The results show that t he former three complexes mainly and strongly coordinate with the phos phate oxygen of dGMP, while cisplatin mainly coordinates with N(7) of dGMP.
