Fragmentation Reactions of Molecular Dications of Aromatic Heterocyclic Fused-ring Compounds Containing More Than One Nitrogen Atom

Fragmentation reactions of both metastable and collisionally activated dications, formed by electron impact ionization of heterocyclic fused-ring aromatic compounds containing more than one nitrogen atom, were investigated.This work is an extension of similar work on analogous compounds containing just one nitrogen atom and on the related polycyclic aromatic hydrocarbons.The results obtained are interpreted in terms of mechanistic proposals concerning the competition between charge-separation and neutral-expulsion reactions, based on variations in diradical characterwith increasing molecular size and nitrogen content of these molecular dications.

Self-assembly of ID- And 3D-networks through non-coordination intermodular forces: Synthesis and crystal structures of copper(I) complexes based on pyridazine-type ligands

Reaction of [Cu2(H3CCN)2(mu-pydz) 3][PF6]2 (1) with an excess of pyridazine or phthalazine yielded the novel dinuclear complexes [Cu2(mu-pydz) 3(pydz)2][PF6]2 (2) and [Cu 2(mupydz)(mu-phtz)2(phtz)2][PF 6]2 (5), respectively. Depolymerisation of the coordination polymer ?1{[Cu(mu-pydz) 2][PF6]} (3) in dichloromethane by addition of an excess of benzo[c]cinnoline afforded the dinuclear copper(I) salt [Cu 2(mu-pydz)2(pydz)2(benzo[c]cinnoline) 2][PF6]2 (4). Furthermore, a new route for the preparation of bis(benzonitrile)tris(mu-phthalazine)dicopper(I) bis(trifluoromethanesulfonate), [Cu2(C6H 5CN)2(i-phtz)3][CF3SO 3]2 (7), was established from {[Cu(CF3SO 3)]2 ¡¤C6H5Me}, phthalazine and benzonitrile via the very air-sensitive intermediate [Cu2(CF 3SO3)2(mu-phtz)3] (6). Copper(I) compounds 2, 4, and 7 were completely characterised and the molecular structures confirmed in the solid state by single-crystal X-ray structure determination. The analysis of the packing of the molecules in crystals of 4 and 7 revealed a self-assembly of oneand three-dimensional frameworks, respectively, resulting from intermolecular pi-pi stacking interactions between pyridazine-type ligands.

Synthesis, biological, anti-inflammatory activities and quantum chemical calculation of some [4-(2, 4, 6-trimethylphenyl)-1(2H)-oxo-phthalazin-2yl] acetic acid hydrazide derivatives

The phthalazine carbohydrazide 2 was prepared and incorporated into the corresponding 1,2,4-triazole and carbamate derivatives. Phthalazine carboxylic acid hydrazide 2 was treated with isatine and cyclo-hexanone to give the corresponding hydrazone derivatives 16, 19 in good yields. Furthermore, alpha-amino acid derivative conjugated with 1-oxophthalazine moiety 35 was synthesized by the reaction of the corresponding aizde 28, via the azide-coupling method, with glycine methyl ester. The peptide ester 35 was converted into their corresponding amide 36 by treating with methanolic ammonia. Moreover, 35 was boiled with hydrazine hydrate to afford the corresponding hydrazide 37. Finally, the dipeptide 38 was prepared by coupling of 35 with L-alanine methyl ester. Some of these compounds were screened in vitro for their antimicrobial activity. The energy gap between the highest occupied molecular orbital and lowest unoccupied molecular orbital has been calculated using the theoretical computations to reflect the chemical reactivity and kinetic stability of compounds.

Visible-Light-Induced Copper-Catalyzed Decarboxylative Coupling of Redox-Active Esters with N-Heteroarenes

Herein we report a protocol for visible-light-induced copper-catalyzed decarboxylative coupling reactions between N-heteroarenes and redox-active esters. Various N-hydroxyphthalimide esters reacted with isoquinoline, quinoline, pyridine, pyrimidine, quinazoline, phthalazine, phenanthridine, and pyridazine to give the corresponding products in modest to excellent yields. The reactions proceed under mild conditions and have a broad scope and high functional group tolerance. Mechanistic studies revealed that the catalytic behavior of CuI photocatalyst generated in situ was consistent with that of preformed [Cu(dmp)(xantphos)]BF4.

The importance of triazole scaffold in the development of anticonvulsant agents

Epilepsy is one of the most important neurological disorders with high prevalence worldwide. Many epileptic patients are not completely treated with available drugs and need multiple therapies. Also, many antiepileptic drugs have shown unwanted side effects and drug interactions. Therefore there are continuing interests to find new anticonvulsant drugs. Triazole ring has been found in the structure of many compounds with diverse biological effects. Due to the success of several triazole-containing drugs that entered the pharmaceutical market as CNS-active drugs, this class of heterocyclic compounds has great importance for discovery and development of new anticonvulsant drugs. In this article, we have tried to summarize the latest efforts which have been made in the design and development of triazole-derived anticonvulsant agents.

Design, synthesis, characterization, QSAR, docking, anti-inflammatory and analgesic evaluation of some new phthalazinediones

Background: phthalazine derivatives were reported to possess anticonvulsant, cardiotonic, antibacterial, analgesic, anti-inflammatory, and anti-microbial activity. In the current study, we applied the QSAR for prediction of newly phthalazinediones incorporating thioamide moiety aiming to reach a more potent anti-inflammatory and Analgesic agent. Methods: Phthalazinediones 10-15 have been synthesized through condensation of dibenzobarallene 3 with thiosemicarbazides 4-8. One equation was predicted using quantitative structure activity relationship (QSAR) and regression analysis for the anti-inflammatory activity with a regression correlation (R) close to unity. The docking studies were performed to investigate the biological trends of the organic compounds (thiol form) against cyclooxygenas- 2 enzyme, which is a responsible inflammation mediator by using Molgro Virtual Docker (MVD) software. The anti-inflammatory activity and analgesic effect of the thioamides 10-15 were determined by collagen II-adjuvant induced paw edema test in rats. Results: Compounds 10, 11, 12, and 14, exhibited promising anti-inflammatory activity. Furthermore, in the pain scoring, compounds 10, 11 and 12 were found to be more effective than piroxicam and the order of the analgesic effect of the investigated compounds is as followed 14 > 12 > 10 > 11 > 15. Conclusion: It is clear from the foregoing that the compound 14 is a promising compound if future pharmacological detailed studies. This is consistent with what has been predictable equation 1 in this study.

Automated assays for von Willebrand factor activity

von Willebrand factor (VWF) ristocetin cofactor activity (VWF:RCo) by platelet aggregometry has been considered the gold standard for evaluating the ability of VWF to bind platelets for over 40 years. Many automated systems no longer require platelets and rather rely on agglutination of latex particles. Automated methods of measuring VWF activity have improved performance characteristics and are performed on the same coagulation instruments used for routine testing via immunoturbidimetric methodology. Alternatively, a newer chemiluminescence assay system for measuring VWF activity demonstrates excellent performance characteristics. As these methods are becoming widely used, it is important to assess their performance in diagnosing and monitoring different types of von Willebrand disease. We review the automated methodologies and the published performance of these VWF assays. Advantages and limitations of these automated methods are discussed.
