  Cisplatin analogues with sulfur donor ligands. (Ethylenediamine)platinum(II) complexes with ligands possessing a sulfinyl or sulfanyl group linked to an anionic oxygen donor atom. Reactivity and cytotoxicity

  摘要：

  Complexes of formula [Pt(en)L]NO3, where en = ethylenediamine and L is a ligand in which a methylsulfinyl or methylsulfanyl group is linked to a carboxylate or phenolate moiety, have been synthesized and characterized by spectroscopic techniques. The ligand L is chelated to Pt via the sulfur and anionic oxygen atoms. The reactivities of these complexes towards nucleophiles [Nu = Cl- or guanosine 5'-monophosphate(2-), GMP] have been investigated by H-1 NMR spectroscopy; GMP is more reactive than Cl-. The Pt-O bonds react more readily than the Pt-S bonds and, depending on the nature of L and Nu, the reactions either stop at the monosubstituted complex [Pt(en)L(Nu)] (with L monodentate and co-ordinated to Pt via the sulfur atom), or yield [Pt(en)(Nu)2]. The complex with L = 2-(methylsulfanyl)phenolate is unreactive. The stable monosubstituted products have been characterized. There is little correlation between the rates and the modes of reactivity of complexes [Pt(en)L]NO3 towards GMP and their cytotoxicities against the human ovarian carcinoma A2780 cell line.

Thiourea and N,N′-dimethylthiourea also react, because they give rise to cyclometallated products [Pt(phos)2(NRC(S)NHR)]+ (R = H, CH3), with one ionised thioamido group, as revealed by an X-ray investigation of [Pt(PPh3)2(NHC(S)NH2)]+.
