Our present results concerning dinuclear platinum(II) complexes with benzenefused aromatic diazines as bridging ligands along with those previously reported for analogous platinum(II) complexes with pyrazine and pyridazine [35,44,48,75] showed that selective cleavage of a peptide molecule containing both methionine and histidine side chains can be achieved by dinuclear platinum(II) complexes containing ortho- and meta-positioned nitrogen atoms in the aromatic diazine-bridging ligand.
The enthalpy of formation in the ideal gas state of the histidine stereoisomers was calculated by means of the same quantity in the crystalline state and of the standard enthalpy of sublimation (Table 6).
