Herein we reported three new platinum(ii)-triarylpyridines complexes with peralkylated ammonium pendants that strongly stabilize G-quadruplex DNA.
Synthesis of diazirinyl organo-platinum complexes, which specifically interact with purine base, characterization of photoreactivity and interaction between guanosine 5'-monophosphate (GMP) were examined. The results indicated that the diazirinyl organo-platinum complex was useful for manipulations of photoaffinity labeled components.
A novel series of platinum (II) complexes was synthesized and the complexes were evaluated for their in vitro cytotoxicity against four human cancer cells lines. Five platinum complexes showed activity against at least one tumor cell line. Complexes 3 and 6 were promising, being active, at micromolar concentrations, against all the assayed tumor cell lines. Compound 3 was selected for further s...
A selected chemical library of six platinum(II) complexes having 1,2-bis(aminomethyl)carbobicyclic ligands were synthesized after a rational design in order to evaluate their antiproliferative activity and the structure-activity relationships. The cytotoxicity studies were performed using cancer cell lines sensitive (A2780) and resistant (A2780R) to cisplatin. Excellent cytotoxicity was observe...
We illustrate a new approach toward the synthesis of a porous supramolecular honeycomb based on triptycene. A coordination polymer has been prepared where the triptycene groups are linked through triptycenesemiquinonediimine platinum complexes, but the product is disordered rather than the intended honeycomb structure. A model platinum complex and its (15)N-labeled isotopomer have been prepared...
Platinum(IV)-based anticancer prodrugs have attracted much attention due to their relative inertness under physiological conditions, being activated inside cells, and their capacity for functionalization with a variety of small-molecule or macromolecule moieties. Novel asymmetric platinum(IV) compounds synthesized through expedient and unique methods are desired. Here we utilize N-bromosuccinim...
We present the synthesis and characterization of six novel bidentate cyclometalated platinum(ii) complexes derived from saturated N-heterocyclic carbene precursors, namely 1-aryl-3-methyl-1H-4,5-dihydroimidazolium salts. The title compounds were then synthesized by a multi-step reaction, which includes an in situ generation silver complex, followed transmetalation to platinum subsequent introdu...
