چکیده
a-Amino Acid Esters, Peptide Esters, Platinum(IV) Complexes, "N NMR Spectra, Pt NMR Spectra The platinum(IV) complexes PtX4L2 (X = Cl, Br; 2 X = oxalate; L = glyOEt, glyglyOEt, gly-cleuOEt; 2 L = metOEt) have been obtained by oxidative addition of halogenes to platinum(II) compounds PtX2L2A high field shift of <3N (—50 ppm) is observed for the coordinated amino acid ligand of various platinum complexes, compared to the free ligand. Platinum(II) and platinum(IV) can be distinguished by their Pt NMR signals.

The binding assessment with human serum albumin of novel six-coordinate Pt(IV) complexes, containing bidentate nitrogen donor/methyl ligands
The interactions between platinum complexes and human serum albumin (HSA) play crucial roles in the distribution, metabolism, and activity of platinum-based anticancer drugs. Octahedral platinum (IV) complexes represent a significant class of anticancer agents that display molecular pharmacological properties different from cisplatin. In this study, the interaction between two Pt(IV) complexes ...
