Ruthenium(II) eta6-arene complexes containing a dinucleating ligand based on 1,8-naphthyridine

Ruthenium arene complexes, [(eta6-p-cymene)2Ru2(L)Cl2](PF6)2 [3b, L = 2, 7-bis(di-2-pyridinyl)-1,8-naphthyridine] and [(eta6-p-cymene)Ru(L?)Cl](PF6) [4, L? = tri(2-pyridinyl)amine], were synthesized and characterized by spectroscopic and analytical techniques. The molecular structure of [(eta6-p-cymene)2Ru2(L)Cl2]Cl2 (3a) was further determined by single-crystal X-ray analysis. The use of these ruthenium complexes as pre-catalysts for oxidative coupling of 1,2-diols/1,2-aminoalcohol with o-phenylenediamines leading to quinoxalines was investigated. Complex 3b appeared to be a good catalyst for this transformation.

Crystal structure, infrared spectra and density functional theory study on 2,3-diketo-benzopiperazine dimer

2,3-Diketo-benzopiperazine, which exists as dimeric form in its crystal structure has been synthesized. The calculated results on the dimer at B3LYP/6-31G* level show that the average strength of the double hydrogen bonds is of medium-grade. Natural bond orbital analyses have been performed. The predicted harmonic vibration frequencies support the experimental values. The thermodynamic properties of the dimer at different temperatures have been calculated and the change of Gibbs free energy for the aggregation from the monomer to the dimer DeltaGr = -30.86 kJ/mol at 298.15 K, which implies the spontaneous process of the dimer formation.

Fragment based design of new H4 receptor-ligands with anti-inflammatory properties in vivo

Using a previously reported flexible alignment model we have designed, synthesized, and evaluated a series of compounds at the human histamine H 4 receptor (H4R) from which 2-(4-methyl-piperazin-l-yl)- quinoxaline (3) was identified as a new lead structure for H4R ligands. Exploration of the structure-activity relationship (SAR) of this scaffold led to the identification of 6,7-dichloro 3-(4-methylpiperazin-l-yl) quinoxalin-2(1H)-one (VUF 10214, 57) and 2-benzyl-3-(4-methyl-piperazin-l-yl) quinoxaline (VUF 10148, 20) as potent H4R ligands with nanomolar affinities. In vivo studies in the rat reveal that compound 57 has significant anti-inflammatory properties in the carrageenan-induced paw-edema model.

Large-scale solvent-free chlorination of hydroxy-pyrimidines,-pyridines,- pyrazines and-amides using equimolar POCl3

Chlorination with equimolar POCl3 can be efficiently achieved not only for hydroxypyrimidines, but also for many other substrates such as 2-hydroxy-pyridines,-quinoxalines, or even-amides. The procedure is solvent-free and involves heating in a sealed reactor at high temperatures using one equivalent of pyridine as base. It is suitable for large scale (multigram) batch preparations.

Design, synthesis and anticancer properties of IsoCombretaQuinolines as potent tubulin assembly inhibitors

The synthesis and evaluation of a new series of IsoCombretaQuinolines (IsoCoQuines) 2 with a 2-substituted-quinoline in place of the 3,4,5-trimethoxyphenyl ring present in isoCA-4 and CA-4 are described. Most of these compounds displayed a potent cytotoxic activity (IC50< 10 nM) against a panel of five human cancer cell lines and inhibited tubulin assembly at a micromolar level. The most potent analogue 2b, having a 3-hydroxy-4-methoxyphenyl as B-ring, led to cell cycle arrest in G2/M phase. Docking studies indicate that 2b showed a binding mode comparable to those previously observed with quinazoline analogous (IsoCoQ) and with isoCA-4 at the colchicine binding site of tubulin.

Studies on synthesis of 2-acetylbenzimidazole and related benzimidazole derivatives

Condensation of o-phenylenediamine (1) with propanoic acid under Phillips’ conditions gives 2-ethylbenzimidazole (2). Attempts to oxidise 2 to 2-acetylbenzimidazole (3) using H2O2, SeO2, KMnO4/acetone were unsuccessful. Condensation of 2 with benzaldehyde yields 2-(alpha-methylstyryl)benzimidazole (4) which on oxidation with KMnO4 gives benzimidazole-2-carboxylic acid (5) as the sole product. Reaction of 1 with pyruvic acid results in 3-methylbenzo-1H-dihydropyrazine-2-one (7) rather than 3 as the major product. Treatment of 1 with formic acid gives the known compound benzimidazole (9) which with acetic anhydride in the presence of NaOAc does not yield 3. Reaction of 1 with lactic acid under Phillips’ conditions gives 2-(alpha-hydroxyethyl)benzimidazole (10) which on oxidation with acid dichromate, however, yields 3. Studies on syntheses and spectral properties of related benzimidazoles are reported.
