Cleavage of the Pt–S bond of thiolated terpyridine–platinum(II) complexes by copper(II) and zinc(II) ions in phosphate buffer

“…The NMR spectrum of [Pt(terpy)-(BAT)] 4+ in D 2 O showed a new downfield peak at d 8.82 and the UV-VIS spectrum displayed the absorbances at 486 nm (e = 698 dm 3 mol 21 cm 21 ), 342 (12 959), 329 (12 397) and 311 (11 903) in phosphate buffer (pH 8.0), which agreed with the characteristic features for establishing the formation of thiolateplatinum bonds in the previous report. 11 In addition, the integration ratio of protons of terpyridine and the triamine moiety in NMR spectra (D 2 O) was approximately 0.93, suggesting no S-bridged diplatinum complex was generated. 14 In the presence of CuCl 2 •6H 2 O (42 mm), the solution of [Pt(terpy)(BAT)] 4+ (40 mm) exhibited a decreasing UV-VIS absorption at 342 nm accompanied by an increasing absorption at 329 nm in phosphate buffer (10 mm, pH 8.0).…”

“…[Pt(terpy)(AET)] + was prepared by published methods. 11 The synthesis of a triamine derivative, [Pt(terpy)(BAT)] 4+ , was achieved by the coupling reaction of [Pt(terpy)Cl] + with the modified multistep synthesis [12][13][14][15] of triaminothiol, 1, in water as illustrated in Scheme 1. The NMR spectrum of [Pt(terpy)-(BAT)] 4+ in D 2 O showed a new downfield peak at d 8.82 and the UV-VIS spectrum displayed the absorbances at 486 nm (e = 698 dm 3 mol 21 cm 21 ), 342 (12 959), 329 (12 397) and 311 (11 903) in phosphate buffer (pH 8.0), which agreed with the characteristic features for establishing the formation of thiolateplatinum bonds in the previous report.…”
