Dinuclear structure of platinum( ii ) complexes favours thermally activated delayed fluorescence (TADF).
Platinum(IV) compounds like oxoplatin (cis, cis, trans-diammine-dichlorido-dihydroxido-platinum(IV)) show increased stability and therefore can be applied orally. In a panel of 38 human cancer cell lines this drug induced S-phase arrest and cell death with IC(50) values 2.5-fold higher than cisplatin. Oxoplatin may be converted to cisplatin by intracellular reducing agents, however, exposure to...
Recently synthesized by the group of Sadler, the platinum(IV) diazido complexes [Pt(N(3))(2)(OH)(2)(L')(L'')] (L' and L'' are N-donor ligands) have potential to be used as photoactivatable metallodrugs in cancer chemotherapy. In the present study optimized structures and UV-Vis electronic spectra of trans,trans,trans- and cis,trans,cis-[Pt(N(3))(2)(OH)(2)(NH(3))(2)] (1t and 1c, respectively) as...
Dichloro-1,2-diaminocyclohexane (DACH):platinum(II), the prototype DACH:platinum complex, had good antitumor activity, was not cross-resistant with cis-dichlorodiammineplatinum(II) (DDP), but was, unfortunately, virtually insoluble in water and was, therefore, not evaluated clinically. This paper summarizes some of the chemical and biological attributes of a series of cis-bisascorbato-DACH:plat...
The concept of Pt(IV) prodrug design is one advanced strategy to increase the selectivity for cancer cells and to reduce systemic toxicity in comparison to established platinum-based chemotherapy. Pt(IV) complexes are thought to be activated by reduction via physiological reductants, such as ascorbic acid or glutathione. Nevertheless, only few investigations on the link between the reduction ra...
The photolytic activation of palladium(II) and platinum(II) complexes [M(BPI)(R)] (R = alkyl, aryl) featuring the 1,3-bis(2-pyridylimino)isoindole (BPI) ligand has been investigated in various solvents. In absence oxygen, formation chloro [M(BPI)Cl] is observed chlorinated solvents, most likely due to degradation solvent HCl. reactivity toward oxygen studied both experimentally computationally....
Symmetrical bis-aryl platinum complexes (DPPF)Pt(C(6)H(4)-4-R)(2) (R = NMe(2), OMe, CH(3), H, Cl, CF(3)) and electronically unsymmetrical bis-aryl platinum complexes (DPPF)Pt(C(6)H(4)-4-R)(C(6)H(4)-4-X) (R = CH(3), X = NMe(2), OMe, H, Cl, F, CF(3); R = OMe, X = NMe(2), H, Cl, F, CF(3); R = CF(3), X = H, Cl, NMe(2); and R = NMe(2), X = H, Cl) were prepared, and the rates of reductive elimination...
the in-situ method of synthesis has been used to isolate oxovanadium(iv) complexes with ligands derived by reaction of benzil with amino acids such as glycine, alanine, serine, cysteine and valine, where template effect of vo +2 cation appears to play an important role. the complexes are characterised by elemental analysis, magnetic moment measurements and spectral (infrared, electronic and ele...
