Synthesis, cytotoxic activity and DNA interaction studies of new dinuclear platinum(ii) complexes with an aromatic 1,5-naphthyridine bridging ligand: DNA binding mode of polynuclear platinum(ii) complexes in relation to the complex structure

The synthesis, spectroscopic characterization, cytotoxic activity and DNA binding evaluation of seven new dinuclear platinum(ii) complexes Pt1-Pt7, with the general formula [{Pt(L)Cl}(2)(-1,5-nphe)](ClO4)(2) (1,5-nphe is 1,5-naphthyridine; while L is two ammines (Pt1) or one bidentate coordinated diamine: ethylenediamine (Pt2), (+/-)-1,2-propylenediamine (Pt3), trans-(+/-)-1,2-diaminocyclohexane (Pt4), 1,3-propylenediamine (Pt5), 2,2-dimethyl-1,3-propylenediamine (Pt6), and 1,3-pentanediamine (Pt7)), were reported. In vitro cytotoxic activity of these complexes was evaluated against three tumor cell lines, murine colon carcinoma (CT26), murine mammary carcinoma (4T1) and murine lung cancer (LLC1) and two normal cell lines, murine mesenchymal stem cells (MSC) and human fibroblast (MRC-5) cells. The results of the MTT assay indicate that all investigated complexes have almost no cytotoxic effects on 4T1 and very low cytotoxicity toward LLC1 cell lines. In contrast to the effects on LLC1 and 4T1 cells, complexes Pt1 and Pt2 had significant cytotoxic activity toward CT26 cells. Complex Pt1 had a much lower IC50 value for activity on CT26 cells compared with cisplatin. In comparison with cisplatin, all dinuclear Pt1-Pt7 complexes showed lower cytotoxicity toward normal MSC and MRC-5 cells. In order to measure the amount of platinum(ii) complexes taken up by the cells, we quantified the cellular platinum content using inductively coupled plasma mass spectrometry (ICP-QMS). Molecular docking studies performed to evaluate the potential binding mode of dinuclear platinum(ii) complexes Pt1-Pt7 and their aqua derivatives W1-W7, respectively, at the double stranded DNA showed that groove spanning and backbone tracking are the most stable binding modes.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 96-49-1 is helpful to your research. Name: Ethylene carbonate.

One-Pot Four-Component Synthesis of 5,10-Diarylpyrido[4,3-b][1,6] Naphthyridine Derivatives in Ionic Liquids Catalyzed by TsOH

A one-pot four-component reaction of aldehyde, aromatic amine, and two equivalents of piperidine-2,4-dione was treated in ionic liquids of [BMIm]Br catalyzed by TsOH (p-toluenesulfonic acid), and gave a series of 5,10-diarylpyrido[4,3-b][1,6]naphthyridine derivatives in good yields. This procedure has the advantages of mild reaction conditions, good yields, one-pot, and environmentally benign.

In a document, author is Seebacher, Werner, introduce the new discover.

1,3-Diphenyl-3,4-dihydrobenzo[b][1,6]naphthyridine

The title compound, C24H18N2, is the first structural example containing the 3,4-dihydrobenzo[b][1,6] naphthyridine fragment. It was synthesized from 2,4,6,8-tetraphenyl-3,7-diaza-bicyclo[3.3.1] nonan-9-one and was crystallized from a methanol-ethanol solution over two years as a racemate. The C=N double bond [1.2868 (15) angstrom] is bent significantly out of the plane of the aromatic bicyclic ring system [N-C-C-C = -157.63 (12)degrees] and out of the plane of the phenyl ring bonded at the 1-position [N-C-C-C = 41.15 (16)degrees].
