Synthesis, characterization, thermal properties and biological activity of diazine-ring containing hydrazones and their metal complexes

New coordination compounds have been synthesized by reacting Zn(II) and Co(II) nitrate or acetate in the presence of triethylamine with Schiff-base ligands containing diazine-ring, pyridine-2-carbaldehyde phthalazine-1-hydrazone,HzPYH, and di(2-pyridyl)ketone 3-chloro-pyridazine-6-hydrazone,HpDPKH. Complexes of[Co(HzPY)(2)]center dot 3.4H(2)O,[Zn(HzPY)(2)]and[Co(HpDPK)(2)]NO3 center dot H(2)Owere obtained. The crystal and the molecular structure of[Co(HzPY)(2)]center dot 3.4H(2)Owere determined using X-ray diffraction structure analysis. The compounds were characterized by elemental analysis, FT-IR and UV-Vis spectral data, conductivity and magnetic measurements, too. Except for the diamagnetic Co(III) compound with a nitrate counter-ion,[Co(HpDPK)(2)]NO3 center dot H2O, all the complexes are neutral-type. The magnetic moment of[Co(HzPY)(2)]center dot 3.4H(2)Oindicated a low-spin octahedral complex which is relatively rear amongst octahedral Co(II) complexes. Hence, its magnetic moment was measured in the temperature range of 3-300 K. To obtain products in the form of single crystals and/or to increase the yield, the reactions were carried out in solutions with different solvents or recrystallized from solvent mixtures. To determine the nature of the solvent (if any) in the crystalline products and to gain better insight into the decomposition mechanism, coupled TG-MS measurements were carried out. The desolvated compounds were stable at relatively high temperatures (> 200 degrees C). The cytotoxic, antiproliferative and efflux pump inhibitory effects of the compounds were tested in multidrug-resistant mouse T-lymphoma cells to study their effect on the suppression of MDR. The antibacterial activity of the compounds was also tested. The results of the antibacterial tests were analysed to understand better the effect of the central atoms and the structure on a specific activity.

Ag NPs on chitosan-alginate coated magnetite for synthesis of indazolo [2,1-b]phthalazines and human lung protective effects

Biocomposite nanomaterials have been evolved as the new generation catalysts and therapeutic supplement in these days. Magnetically isolation has added new features to this category. This has encouraged us to synthesize a novel Ag NP adorned chitosan-alginate dual bio-polysaccharide (two of the more versatile polysaccharides) modified core-shell magnetic nanocomposite (Fe3O4/CS-Alg/Ag NPs). The material was meticulously characterized following different physicochemical techniques, such as, FT-IR, ICP-OES, FESEM, EDX, atomic mapping, TEM, VSM, XRD and XPS studies. The as synthesized material was catalytically explored in the one-pot multicomponent synthesis of biologically potent 2H-indazolo[2,1-b]phthalazine-trione derivatives involving a wide range of substrates. The reactions were ended up with excellent yields under solvent-free heating conditions. The catalyst recyclability, heterogeneity and leaching tests were performed to ensure its high stability and robustness. It could be reused as much as 10 times in succession with almost unchanged catalytic performances. In the lung protective part of the present research, the human lung toxicity was induced by alpha-Guttiferin. The cell viability of lung MRC-5, CCD-19Lu, WI-38, and BEAS-2B cell lines was measured by trypan blue assay. Caspase-3 activity was assessed by the caspase activity colorimetric assay kit and mitochondrial membrane potential of lung cells was studied by Rhodamine123 fluorescence dye. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) test was used to show DNA fragmentation and apoptosis of lung cells. Also, the Rat inflammatory cytokine assay kit was used to measure the concentrations of inflammatory cytokines. The catalyst-treated cell cutlers significantly (p <= 0.01) reduced the DNA fragmentation, caspase-3 activity, and inflammatory cytokines concentrations, and raised the mitochondrial membrane potential and cell viability in the high concentration of alpha-Guttiferin-treated lung MRC-5, CCD-19Lu, WI-38, and BEAS-2B cells. The best result of lung protective properties of catalyst against alpha-Guttiferin was seen in the high dose of catalyst i.e., 4 mu g. DPPH test revealed similar antioxidant potentials for catalyst and butylated hydroxytoluene. The catalyst inhibited half of the DPPH molecules in the concentration of 171 mu g/mL. According to the above results, catalyst can be administrated as a lung protective drug for the treatment of lung diseases after approving in the clinical trial studies in humans.

Tetrakis(acetonitrile)copper(I) Hexafluorophosphate as an Efficient Catalyst for the Synthesis of Triazolo[1,2-a]indazole-1,3,8-trione and 2H-indazolo[2,1-b]phthalazine-trione Derivatives

Tetrakis(acetonitrile) copper(I) hexafluorophosphate, [Cu(CH3CN)(4)]PF6, was explored as an efficient catalyst to promote the three-component reaction of aryl aldehydes, dimedone and urazole or phthalhydrazide to afford the corresponding triazolo[1,2-a]indazole-1,3,8-trione and 2H-indazolo[2,1-b]phthalazine-trione derivatives respectively in high yields. The reactions were conducted at 80-100 degrees C under solvent-free conditions. The catalyst was easily prepared from available and inexpensive materials and was quantitatively recovered from the reaction by simple filtration and reused for a number of cycles with almost consistent activity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 54381-16-7. Quality Control of 2,2′-((4-Aminophenyl)azanediyl)diethanol sulfate.

Azines and Azoloazines, Part 1: Reactions of Triazolo[3,4-a]phthalazine and Its Derivatives with Carbanions

Triazolo[3,4-a]phthalazine as well as their chloro and nitro derivatives were subjected to the reactions with the carbanions typical for the vicarious nucleophilic substitution (VNS) of hydrogen. The reactions were strongly dependent on the substituents present on the triazolo[3,4-a]phthalazine ring and resulted not only in the substitution of hydrogen but also in exchange of chlorine atom and pyridazine ring scission; the latter process dominated for the unsubstituted triazolophthalazine. Two of the products showed promising stimulating activity towards the central nervous system with no significant toxic effects.

Tel-Cu-NPs Catalyst: Synthesis of Naphtho[2,3-g]phthalazine Derivatives as Potential Inhibiters of Tyrosinase Enzymes and Their Investigation in Kinetic, Molecular Docking, and Cytotoxicity Studies

Novel one-pot synthesis naphtho[2,3-g]phthalazine (1a-1k) of Mannich base derivatives can be achieved via grindstone chemistry using a Tel-Cu-NPs (telmisartan-copper nanoparticles) catalyst. This method offers efficient mild reaction conditions and high yields. Tyrosinase inhibitory activity was evaluated for all synthesized compounds, along with analysis of kinetic behavior and molecular docking studies. The synthesized compound, 1c was (IC50 = 11.5 mu M) more active than kojic acid (IC50 = 78.0 mu M). Lineweaver Burk plots were used to analyze the kinetic behavior of the most active compound 1c, it was reversible and competitive behavior. Compound 1c and kojic acid occurred in the presence of 2-hydroxyketone, which has the same inhibitory mechanism. The molecular docking of compound 1c and the control kojic acid were docked against 2Y9X protein via the Schrodinger Suite. The compound 1c showed a respectable dock score (-5.6 kcal/mol) compared to kojic acid with a dock score of (-5.2 kcal/mol) in the 2Y9X protein. Cytotoxicity activity was also evaluated by using HepG2 (liver), MCF-7 (breast), and HeLa (cervical) cancer cell lines, and high activity for 1c (GI(50) = 0.01, 0.03, and 0.04 mu M, respectively) against all cell lines was found compared to standard and other compounds. Therefore, this study succeeded in testing a few promising molecules as potential antityrosinase agents.

Pyridazine-Containing Diazatwistanthracene and Tetraazatwisttetracene: Synthesis, Crystal Structures and Third Order Non-linear Optical Properties

In this paper, two pyridazine-heterocycles-containing azaacenes 9,12-diphenylphenanthro[4,5-fgh]phthalazine (DPPA) and 2,9-di-tert-butyl-4,7,11,14-tetraphenylpyridazino[4′,5′:9,10] phenanthro[4,5-fgh]phthalazine (TPPA) have been synthesized and fully characterized. The single crystal analysis of TPPA showed that TPPA molecule exhibits a twisted structure with the dihedral angel of 27 degrees between pyrene and pyridazine unit, which suppresses the pi-pi stackings in the solid state. The two-photon absorption properties of DPPA and TPPA were investigated, respectively, by using the femtosecond Z-scan technique. The results showed that both DPPA and TPPA showed moderate two-photon absorption cross-section values, and the larger one was found to be 454 GM with TPPA. Obviously, the introduction of pyridazine ring into the skeleton of acenes forming a A-D-A structure could lead to a much larger two-photon absorption coefficient and two-photon absorption cross section.

Synthesis and vasorelaxant and antiplatelet activities of a new series of (4-Benzylphthalazin-1-ylamino)alcohol derivatives

A new series of phthalazine derivatives was synthesized by reaction of phthalic anhydride and different substituted phenylacetic acids to yield the benzyliden-3H-isobenzofuran-1-one intermediates 2a-d. Treatment of them with hydrazine afforded 4-benzyl-2H-phthalazin-1-one derivatives 3a-d, which were substituted with the corresponding aminoalkylalcohol to obtain the (4-benzylphthalazin-1-ylamino)alcohol derivatives 4a-h. In general, these phthalazine derivatives relaxed the contractions produced by phenylephrine both in intact or endothelium-denuded aortic rings. In addition, platelet aggregation induced by thrombin was also inhibited by compounds 4c and 4g.
