The question of whether monofunctional DNA platinum(II) adducts block synthesis of DNA by purified DNA polymerases of different types and origin has been investigated by comparing the time dependence of synthesis arrest and of DNA adduct formation. Activated salmon testis DNA is used as a suitable substrate for DNA synthesis allowing to probe inhibition by platinum(II) monoadducts for the varie...

The trinuclear BBR3464 ([{trans-PtCl(NH(3))(2)}(2)µ-(trans-Pt(NH(3))(2)(H(2)N(CH(2))(6)NH(2))(2))](4+)) belongs to the polynuclear class of platinum-based anticancer agents. DNA adducts of this complex differ significantly in structure and type from those of clinically used mononuclear platinum complexes, especially, long-range (Pt, Pt) intrastrand and interstrand cross-links are formed in both...

A series of platinum(II) complexes with 1,3-bis(2-pyridylimino)isoindoline (BPI) derivatives were prepared by substitution of the coordinated Cl in the precursor complex Pt(BPI)Cl with a N-heterocyclic ligand such as pyridine, phthalazine or phenanthridine. These complexes display orange to red luminescence in fluid dichloromethane solutions and in the solid states at room temperature. The phot...

Correction for 'Platinum complexes as light promoted anticancer agents: a redefined strategy for controlled activation' by Koushambi Mitra, et al., Dalton Trans., 2016, 45, 19157-19171.

The incorporation of platinum(II) complexes into block copolymers leads to the formation of luminescent polymeric hybrids with hierarchical nanostructures from spherical, rodlike micelles to vesicles in solvents.

Steroidal compounds exhibit particular physiological activities. In this paper, some steroidal thiosemicarbazones platinum (Pt(II)) complexes were synthesized by the condensation of steroidal ketones with thiosemicarbazide using estrone, chenodeoxycholic acid, and 7-deoxycholic acid as starting materials and complexation of steroidal thiosesemicarbazones with Pt(II). The complexes were characte...

The preparation of Pt(ii) complexes of the type trans-L2Pt(Ar)Cl, L2Pt(Ar)2, and L2Pt(Ar)(Ar') (L = PBu3, Ar = arylene) by CuI catalyzed reaction of cis-(PBu3)2PtCl2 with aryl-stannanes is reported. The reactions proceed at 25-60 °C in moderate to good yields. The reaction is demonstrated to occur with phenyl- and 2-thienyl-stannanes that include a variety of functionality, and all of the resul...

A wide range of research activities have been carried out so far on benzimidazole and pyridine derivatives to evaluate their Antiviral, Anticancer, Anticonvulsant, Anthelmintic Activity and many promising results are obtained with respect to the anticancer activity. Out of the various ligands used, the alkylating agents are found to be highly active with respect to cancer chemotherapy. Nitrogen...

This perspective summarizes the chemistry of platinum metal complexes of β-diiminate ligands bearing aryl groups at the nitrogen atoms. While β-diiminate ligands mostly coordinate in a κ(2)-N,N' mode, palladium complexes have a tendency to rearrange to C-bound structures (κ(2)-N,C or μ-N,N':C). Diiminate ligands are remarkably effective at stabilizing coordinatively unsaturated metal centers, a...
