Dinuclear Platinum Complexes with Biological Relevance Based on the 1,2-Diaminocyclohexane Carrier Ligand
摘要:
The synthesis of bifunctional dinuclear platinum complexes, [{PtCl-(dach)} (2)-mu-Y]Cl-n+(n) (1-3;Y = H2N(CH2)(3)NH2(CH2)(4)NH2, H2N(CH2)(6)NH2(CH2) 6NH2, and H2N(CH2)(6)NH2(CH2)(2)NH2(CH2)(6)NH2, respectively; Figure 1) is reported. There was no labilization of the polyamine linker groups of the cis-1,2-diaminocyclohexane complexes in the presence of sulfur-containing species at physiological pH, in contrast to previous studies preformed on trans complexes. Metabolism reactions are somewhat dependent on the nature of the polyamine: at physiological pH, the spermidine complex 1 forms an inert (tetraamine) platinum species in which one platinum is chelated by a central and terminal amino group. The stability of cis-geometry complexes may make them viable second-generation polynuclear platinum clinical candidates.
