The molecular hydrogen complex of osmium, [trans-en2Os (ŋ-H2)]2+ (en, entlylendediamine) is a new1H NMR recognition probe for biomolecules. By using this probe, the coordination between deoxyguanylic acid (dGMP) and four metal anticancer complexes, titanocene dichloride, (C2H5)2SnCl2(phen). (C2H5)2SnCl2 and cisplatin are studied in D2O under the condition near the physiological one. The results show that the former three complexes mainly and strongly coordinate with the phosphate oxygen of dGMP,...

Abstract This contribution reports a solution and solid-state study of the aqueous nucleotide coordination chemistry of the dieihyltin(IV) antitumor agent, (C 2 H 5 )2SnC1 2 (phen). [trans-en 2 OS(η-H 2 ] (CF 3 SO 3 ) 2 , a versatile 1 H NMR probe for biomolecules, is first used to investigate the interaction of (C 2 H 5 ) 2 SnC1 2 (phen) with DGMP in neutral aqueous solution, and then the synthesis of mixed-ligands complexes formulated as (C 2 Hn5) S nC1(phenXNu) (Nu is nucleotide) by reactions...
