Synthesis and Magnetostructural Characterization of Dinuclear Copper(II) Complexes with the Diazine Ligand, 3,6-Bis(di-2-pyridylmethyl)pyridazine

The crystal structures of *2CH3CN 1, Cl*3.5H2O 2 and 4 3 were determined by X-ray analysis, where bdpdz represents the binucleating ligand 3,6-bis(di-2-pyridylmethyl)pyridazine, formed by the reaction of 3,6-dichloropyridazine and di-2-pyridylmethyllithium.Compounds 1 and 2 consist of discrete binuclear units, in which copper atoms are linked by the diazine bridge and two halide ions.The pyridazine acts as a hexadentate ligand.In complex 2 the two copper(II) ions have a distorted octahedral co-ordination geometry, 4 + 2.Compound 3 also consists of discrete binuclear units, in which the copper centres are linked by two organic ligands.Here bdpdz acts as a pentadentate ligand, with one of the diazine nitrogen atoms not bonded.The two copper(II) ions have a square pyramidal co-ordination geometry, 4 + 1.The magnetic susceptibility was investigated in the temperature range 300-5 K.These measurements reveal an antiferromagnetic interaction for all three compounds (-2J = 98.1 for 1, 79.6 for 2 and 6.4 cm-1 for 3).The lack of a diazine bridge, N-N, for the perchlorate salt 3 substantially reduces the antiferromagnetic interaction.

Discovery and characterization of 6-{4-[3-(R)-2-methylpyrrolidin-1-yl) propoxy]phenyl}-2H-pyridazin-3-one (CEP-26401, irdabisant): A potent, selective histamine H3 receptor inverse agonist

Optimization of a novel series of pyridazin-3-one histamine H3 receptor (H3R) antagonists/inverse agonists identified 6-{4-[3-(R)-2-methylpyrrolidin-1-yl)propoxy]phenyl}-2H-pyridazin-3-one (8a, CEP-26401; irdabisant) as a lead candidate for potential use in the treatment of attentional and cognitive disorders. 8a had high affinity for both human (Ki = 2.0 nM) and rat (Ki = 7.2 nM) H3Rs with greater than 1000-fold selectivity over the hH1R, hH2R, and hH4R histamine receptor subtypes and against an in vitro panel of 418 G-protein-coupled receptors, ion channels, transporters, and enzymes. 8a demonstrated ideal pharmaceutical properties for a CNS drug in regard to water solubility, permeability and lipophilicity and had low binding to human plasma proteins. It weakly inhibited recombinant cytochrome P450 isoforms and human ether-a-go-go-related gene. 8a metabolism was minimal in rat, mouse, dog, and human liver microsomes, and it had good interspecies pharmacokinetic properties. 8a dose-dependently inhibited H3R agonist-induced dipsogenia in the rat (ED50 = 0.06 mg/kg po). On the basis of its pharmacological, pharmaceutical, and safety profiles, 8a was selected for preclinical development. The clinical portions of the single and multiple ascending dose studies assessing safety and pharmacokinetics have been completed allowing for the initiation of a phase IIa for proof of concept.

Highly selective and sensitive determination of copper ion based on a visual fluorescence method

A novel ratiometric fluorescence sensor for rapid and on-site visual detection of Cu2+ was designed and synthesized by integrating yellow-emission rhodamine fluorophore (RL) and red-emission CdTe@SiO2 QDs. The as-prepared nanohybrid fluorescence sensor shows dual-emissions at 537 nm and 654 nm under a single excitation at 500 nm in the presence of Cu2+. Owing to the strong chelating ability of RL toward Cu2+, the yellow fluorescence of RL could be selectively enhanced while the red fluorescence of CdTe QDs is almost unchanged, leading to an obvious fluorescence color change from red to yellow, which could be used for visual and ratiometric detection of Cu2+. This nanohybrid sensor exhibits excellent selectivity, sensitivity and anti-interference to Cu2+ detection and the detection limit is as low as 8.4 nM. Additionally, a simple device test strip for rapid and on-site detection of Cu2+ has been designed by immobilizing the RL-CdTe@SiO2 QDs on a common filter paper. This simple and effective paper-based sensor has a visual detection limit of 0.5 muM, showing its promising application for on-site and rapid sensing of Cu2+ in pollution water.

Synthesis, molecular modelling and biological activity of some pyridazinone derivatives as selective human monoamine oxidase-B inhibitors

Background: Since brain neurotransmitter levels are associated with the pathology of various neurodegenerative diseases like Parkinson and Alzheimer, monoamineoxidase (MAO) plays a critical role in balancing these neurotransmitters in the brain. MAO isoforms appear as promising drug targets for the development of central nervous system agents. Pyridazinones have a broad array of biological activities. Here, six pyridazinone derivatives were synthesized and their human monoamine oxidase inhibitory activities were evaluated by molecular docking studies, in silico ADME prediction and in vitro biological screening tests. Methods: The compounds were synthesized by the reaction of different piperazine derivatives with 3 (2H)-pyridazinone ring and MAO-inhibitory effects were investigated. Docking studies were conducted with Maestro11.8 software. Results: Most of the synthesized compounds inhibited hMAO-B selectively except compound 4f. Compounds 4a?4e inhibited hMAO-B selectively and reversibly in a competitive mode. Compound 4b was found as the most potent (ki = 0.022 ¡À 0.001?muM) and selective (SI (Ki hMAO-A/hMAO-B) = 206.82) hMAO-B inhibitor in this series. The results of docking studies were found to be consistent with the results of the in vivo activity studies. Compounds 4a?4e were found to be non-toxic to HepG2 cells at 25?muM concentration. In silico calculations of ADME properties indicated that the compounds have good pharmacokinetic profiles. Conclusion: It was concluded that 4b is possibly recommended as a promising nominee for the design and development of new pyridazinones which can be used in the treatment of neurological diseases.

Facile access to mono-cinchona alkaloid-derived ligands

Two facile accesses to mono-cinchona alkaloid-derived ligands, by conventional heating conditions and solvent-free microwave irradiation, are described. 1,4-Dichlorophthalazine (PHAL) or 3,6-dichloropyridazine (PYDZ) reacted with quinine (QN), cinchonine (CN), or cinchonidine (CND) by using CaH2 as acid-bonding reagent in DMF at 90-100C to provide mono-cinchona alkaloid-derived ligands 2a-f (87-95%) in 1.5 h. However, the coupling reactions were performed under solvent-free microwave conditions to yield 2a-f (64-89%) within 15 min. Copyright Taylor & Francis Group, LLC.
