Synthesis, characterization, and anti-rheumatic potential of phthalazine-1,4-dione and its Cu(II) and Zn(II) complexes

Two new metal complexes derived from the reaction of 2-[(2-hydroxybenzoyl) 2,3,4a,5,10,10a-hexahydro-5,10[1′,2′]-benzenobenzo[g]phthalazine-1,4-dione] (HBPD) with Cu(II) and Zn(II) have been synthesized and characterized by using elemental analysis, spectral analysis (UV-Vis, IR, H-1 NMR, C-13 NMR), conductance, thermal analysis, and magnetic moments. The in vivo collagen-adjuvant arthritis model in rats revealed a significant antioxidant, analgesic, and anti-rheumatic effects for HBPD and its copper and zinc complexes in comparison with standard piroxicam. The results showed that, the investigated Cu and Zn complexes have higher anti-inflammatory activity than the free ligand.

Introducing new and effective catalysts for the synthesis of pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine derivatives

In this study, a new and effective catalyst for the synthesis of pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine derivatives was introduced. Triethanolammonium acetate ([TEAH][OAc]) accelerates the reaction in a one-pot and four-component condensation of aldehydes, hydrazine hydrate, succinic/phthalic anhydride, and 1,3-dicarbonyl compounds. The yield of the products is high, and the reaction conditions are mild and solvent-free. Furthermore, the model reaction was conducted in the presence of triethanolammonium sulphate ([TEAH][HSO4] and triethanolammonium formate ([TEAH][HCOO]) under various conditions. In addition, the catalyst is recyclable, therefore, it can be reused several times. The structure of the obtained products was confirmed by comparing the M.P., IR, and H-1 NMR. Advantages of this technique are as following: Synthesis of novel, green, and one-pot and four-component condensation (4CC) under solvent-free conditions at room temperature. The catalytic reaction is performed under mild and environmentally friendly conditions in short reaction times and excellent yields. The catalyst is easily recycled and exhibits good chemical and structural stability. (C) 2020 The Author(s). Published by Elsevier B.V.

Organoacid-Decorated NiFe2O4 Nanoparticles: An Efficient Catalyst for Green Synthesis of 2H-Indazolo[2, 1-b]phthalazine-Triones and Pyrimido[1,2-a]benzimidazoles

Organo-Sulfonic acid tags anchored on magnetic titana coated NiFe2O4 nanoparticles (nano-NiFe2O4@TiO2-SiO2-Pr-DEA-OSO3H) was prepared and characterized by various analysis methods including Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), vibrating sample magnetometer (VSM), X-ray diffraction (XRD) and thermo gravimetric analysis (TGA). These modified nanoparticles were used as efficient and recoverable hybrid nanocatalyst in multicomponent synthesis of some phthalazine-trione and benzo[4,5]imidazo[1,2-a]pyrimidine derivatives under green conditions. High yields within shorter reaction times, simple purification, and environmentally mild reaction conditions are some advantages of this protocol.

Organocatalytic, Enantioselective Dichlorination of Unfunctionalized Alkenes

The use of a new class of unsymmetrical cinchona-alkaloid-based, phthalazine-bridged organocatalysts enabled the highly enantioselective dichlorination of unfunctionalized alkenes. In combination with the electrophilic chlorinating agent 1,3-dichloro-5,5-dimethylhydantoin (DCDMH) and triethylsilyl chloride (TES-Cl) as the source of nucleophilic chloride, 1-aryl-2-alkyl alkenes were dichlorinated with enantioselectivities of up to 94:6 er. Initial mechanistic investigations suggest that no free chlorine is formed, and by replacement of the chloride by fluoride, enantioselective chlorofluorinations of alkenes are possible.

Application of O-sulfonic acid poly(4-vinylpyrrolidonium) chloride as an efficient polymer-supported catalyst in the rapid synthesis of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products

In this work, a series of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products were efficiently synthesized for the first time using O-Sulfonic acid poly(4-vinylpyrrolidonium) chloride ([PVP-SO3H]Cl) as an eco-friendly polymer-supported catalyst. At first, the catalyst preparation process was optimized based on the chlorosulfonic acid amount and the sulfonation time to obtain a catalyst with the maximum acidity content. The maximum acidity content for [PVP-SO3H]Cl was obtained to be 3.31 mmol g(-1). Then, the optimized [PVP-SO3H]Cl was used as a catalyst for the synthesis of a series of 2H-indazolo[2,1-b]phthalazine-triones and Biginelli-like products. It was observed that only 10 mg of the catalyst was enough to catalyze these reactions under mild conditions, and the corresponding products were obtained in high to excellent yields. Moreover, the catalyst could be repeatedly used for at least five times without a noticeable decrease in its catalytic activity.

Synthesis and Antitumor Activity of Novel 1,3-Disubstituted Pyridazinone Derivatives

In order to find more efficient and low toxicity antitumor drugs, a series of novel 1,3-disubstituted pyridazinone derivatives were synthesized and evaluated for their antiproliferative activities against four human cancer cell lines (MCF-7, PC-3, SW-620 and HGC-27) in vitro. The results showed that most compounds had good antiproliferative activities, especially 2-(4-(4-bromophenyl)-1-oxo-tolylazine-2(1H)-yl)-N-(2-fluorophenyl)acetamide (5g) exhibited better antiproliferative activities with IC50 value of 6.01 mu mol/L. In a nutshell, this work provided clues to discover antitumor agent based on the quinazoline scaffold.

Crystallographic Study on the Structure of 5,6,7,8-Tetrahydro-1,4-di (2 ‘-pyridyl) Phthalazine

The solid-state structure of 5,6,7,8-tetrahydro-1,4-di(2’-pyridyl)phthalazine (6-dppn) was characterized by X-ray diffraction and a crystallographic study was then conducted. It was found that 6-dppn exists in the trans/trans conformation. This ligand crystallizes in P2(1)/c(14) space group with unit cell parameters of a = 9.698(2) angstrom, b = 9.999(4) angstrom, c = 10.7268(3) angstrom, beta = 92.890(6)degrees, Z = 8 and V = 2958.2(14) angstrom(3). The non-covalent interactions involved in the structure of 6-dppn were investigated and presented in terms of supramolecular chemistry and crystal engineering.

Synthesis of new (trifluoromethyl)-1H-benzo[e][1,2,4]triazolo[1,2-a] [1,2,4]triazine-1,3(2H)-diones and (trifluoromethyl)benzo[5,6][1,2,4] triazino [1,2-b]phthalazine-8,13-diones

In this paper we investigated reactions of urazole and phthalazine with N-(aryl)-2,2,2-trifluoroacetimidoyl chloride derivatives. Results showed that when imidoyl chloride derivative has a fluorine atom at ortho position (3a-c), in two steps under a S(N)i mechanism and then SNAr reaction mechanism produce ay1-5-(trifluoromethyl)-1H-benzo [el [1,2,4]triazolo[1,2-a] [1,2,4]triazine-1,3(2H)-diones (4a-c) and 6-(trifluoromethyl)benzo[5,6][1,2,4]triazino[1,2-b]phthalazine-8,13-diones (4i,4j) in good to excellent yields. In the other imidoyl derivatives (3d-h and 3i,3j) under these conditions cyclization reaction does not occur and therefore produce 1-aryl-2,2,2-trifluorornethyl)-4-phenyl-1,2,4-triazolidine-3,5-diones (4d-h) and 2-(2,2,2-trifluoro-1-(arylimino)ethyl)-2,3-dihydrophthalazine-1,4-diones(4k,41) (non-cyclic products) in good to excellent yields.

EPR spectral study of copper(II) chelates with hetarylhydrazones of glyoxylic acid

Structure of copper(II) chelates based on glyoxylic hetarylhydrazones containing benzazole (quinoxaline and phthalazine) fragments have been studied by EPR spectroscopy. Spectral parameters in polycrystalline state and dimethylformamide solutions have been determined. Spectral parameters of benzimidazole derivative are typical for square planar structure of the chelate node, while phthalazine derivative displays formation of polymeric structures due to reduction of copper(II) atom.
