Green synthesis of 1H-pyrazolo[1,2-b]phthalazine-2-carbonitrile derivatives using a new bifunctional base-ionic liquid hybrid magnetic nanocatalyst

The ionic liquid-base N,N,2,2,6,6-hexamethyl-N-(3-(trimethoxysilyl)propyl)piperidin-4-amonium iodide was grafted onto titana-coated NiFe2O4 nanoparticles for obtaining an efficient and reusable ionic liquid-base hybrid nanocatalyst. The structure of hybrid nanoparticles was characterized using FT-IR (Fourier-transform infrared spectroscopy), field emission scanning electron microscopy, EDS (energy-dispersive X-ray spectroscopy), EDS map scan, Brunauer-Emmett-Teller surface area analysis, CHN (elemental analysis), vibrating sample magnetometer and thermogravimetric analysis techniques. Furthermore, this novel hybrid catalyst was used in one-pot three-component synthesis of 3-amino-1-aryl-5,10-dioxo-1H-pyrazolo[1,2-b]phthalazine-2-carbonitrile derivatives under green and environmentally benign conditions. This protocol avoids the use of harmful catalysts, toxic solvents and harsh reaction conditions. The products were synthesized in excellent yields within short reaction time and identified using elemental analysis, FT-IR, H-1 NMR and C-13 NMR spectroscopies.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 58743-75-2, in my other articles.

Synthesis of phthalazine derivative based organic nanoflakes in aqueous solvent as a potential nano-anticancer agent: A new approach in medical field

A simple phthalazine derivative 13-(4-bromophenyl)-3,3-dimethyl-3,4-dihydro-1H-indazolo[1,2-b] phthalazine-1,6,11(2H,13H)-trione (IDP) was synthesized by Knoevenagel condensation with Michael addition reaction. The present articles deals with preparation of highly fluorescent nanoparticles as prepared drug (IDP) by simple reprecipitation method using single aqueous solvent. The DLS measurement predicted the 150 nm size of a synthesized IDP NPs. Furthermore UV-Visible and fluorescence spectroscopy measurement showed a distinct peak for IDP NPs from their parent molecule. Scanning Electron Microscopy (SEM) microphotograph of air dried film of nanoparticles exhibited nanoflakes type and feathery morphology. The highly fluorescent nature of IDP NPs ultimately revealed in high quantum yield than IDP parent molecule. These fluorescent organic nanoflakes then further applied as anticancer agent. Interestingly it showed better activity than IDP molecules. Thus this is the first report to use organic nanoflakes as an anticancer agent, which may open new avenues in medical field’s and related sciences. (C) 2019 Elsevier B.V. All rights reserved.

Synthesis of some pyridazine derivatives as antioxidants and antimicrobial agents

Purpose: To prepare some pyridazine derivatives as antioxidant and antimicrobial agents. Methods: The coupling of aryl diazonium salts with diethyl 2-cyano-3-methylglutaconate afforded pyridazine-5-carbonitrile derivatives (3a-e). The methyl function in the pyridazine derivatives (3a-e) reacted with cinnamonitriles to yield phthalazine derivatives (6a-h). Imino-pyridazine derivatives (9a-h) were obtained by reacting 2-aminoprop-1-ene-1,1,3-tricarbonitrile along with aryl diazonium salts (1a-h). Structure elucidation was done by spectral analysis. The 1,1-diphenyl-2-picryl hydrazyl (DPPH) technique was employed to assess antioxidant effect, while evaluation of antimicrobial activity was carried out by serial dilution technique. Results: Compounds, 6f (IC50 = 12.68 mu g/mL; p < 0.05), 6a (IC50 = 14.23 mu g/mL; p < 0.05), and 3c (IC50 = 14.34 mu g/mL; p < 0.05) displayed good antioxidant activity compared to ascorbic acid (IC50 = 12.45 mu g/mL; p < 0.05). Based on the zone of inhibition, compound 6c (p < 0.05) displayed higher activity than ofloxacin (p < 0.05) against E. coli. Conclusion: The presence of an oxo group and carboxylate group plays an important role in the antioxidant activity of these compounds. Compounds 6a, 6f, and 3c can potentially serve as lead compounds for the development of promising antioxidants. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 524-95-8.

Synthesis, vasorelaxant activity, and molecular modeling study of some new phthalazine derivatives

New phthalazine-based vasodilators were synthesized through the chloroacylation of the starting compound 1-hydrazinophthalazine 4 to give the two key intermediates 5 and 7. These intermediates were used to alkylate various cyclic amines to furnish the final compounds 6a-h and 8a-h. Compounds were tested for their vasorelaxant activities against nor-adrenaline-induced spasm on thoracic rat aorta rings and compared to the reference drug, prazosin. Seven compounds showed higher activity than prazosin, especially compound 8d having an IC50 = 0.10 mM. Molecular modeling studies, including fitting of the synthesized compounds to a 3D-pharmacophore and their docking into optimized homology model as alpha(1)-AR antagonists showed high docking score and fit values. Most vasodilation activities of tested compounds are consistent with their molecular modeling results. (C) 2012 Elsevier Masson SAS. All rights reserved.

Deep eutectic solvent an efficient reaction medium for the synthesis of chromeno pyrazolo and indazolo phthalazine derivatives

The volatile, harmful and hazardous solvents have impact on human health, all organisms and environment. To reduce the use of hazardous volatile solvents, there is need to develop the alternative green reaction medium for organic transformations and is the main goal of green chemistry. The green solvent should be nonvolatile, nontoxic, biodegradable and biorenewable. Considering these parameters, herein, we have reported an efficient and environmentally benign green synthesis of chromeno pyrazolo and indazolo phthalazine derivatives in deep eutectic solvent. The present protocol contains excellent yield of the product, short reaction time, operation simplicity, reusability of solvent and no need of further purification.

Quinazoline and phthalazine derivatives as novel melatonin receptor ligands analogues of agomelatine

For further development of successors of Agomelatine through modulation of its pharmacokinetic properties, we report herein the design, synthesis and pharmacological results of a new family of melatonin receptor ligands. Issued from the introduction of quinazoline and phthalazine scaffolds carrying an ethyl amide lateral chain and a methoxy group as bioisosteric ligands analogues of previously developed Agomelatine. The biological activity of the prepared analogues was compared with that of Agomelatine. Quinazoline and phthalazine rings proved to be a versatile scaffold for easy feasible MT1 and MT2 ligands. Potent agonists with sub-micromolar binding affinity were obtained. However, the presence of two nitrogen atoms resulted in compounds with lower affinity for both MT1 and MT2, in comparison with the parent compound, balanced by the exhibition of good pharmacokinetic properties.
