In vitro leishmanicidal activity of imidazole- or pyrazole-based benzo[g]phthalazine derivatives against Leishmania infantum and Leishmania braziliensis species

Objectives: To evaluate the in vitro leishmanicidal activity of imidazole-based (1-4) and pyrazole-based (5-6) benzo[g] phthalazine derivatives against Leishmania infantum and Leishmania braziliensis. Methods: The in vitro activity of compounds 1-6 was assayed on extracellular promastigote and axenic amastigote forms, and on intracellular amastigote forms of the parasites. Infectivity and cytotoxicity tests were performed on J774.2 macrophage cells using meglumine antimoniate (Glucantime) as the reference drug. The mechanisms of action were analysed by iron superoxide dismutase (Fe-SOD) and copper/zinc superoxide dismutase (CuZn-SOD) inhibition, metabolite excretion and transmission electronic microscopy (TEM). Results: Compounds 1-6 were more active and less toxic than meglumine antimoniate. Data on infection rates and amastigote mean numbers showed that 2, 4 and 6 were more active than 1, 3 and 5 in both L. infantum and L. braziliensis. The inhibitory effect of these compounds on the antioxidant enzyme Fe-SOD of promastigote forms of the parasites was remarkable, whereas inhibition of human CuZn-SOD was negligible. The ultrastructural alterations observed in treated promastigote forms confirmed the greater cell damage caused by the most active compounds 2, 4 and 6. The modifications observed by 1H-NMR in the nature and amounts of catabolites excreted by the parasites after treatment with 1-6 suggested that the catabolic mechanisms could depend on the structure of the side chains linked to the benzo[g] phthalazine moiety. Conclusions: All the compounds assayed were active in vitro against the two Leishmania species and were less toxic against mammalian cells than the reference drug, but the monosubstituted compounds were significantly more effective and less toxic than their disubstituted counterparts.

Improvement of antibacterial activity of some sulfa drugs through linkage to certain phthalazin-1(2H)-one scaffolds

RAB1 5 is a lead antibacterial agent in which trimethoprim is linked to phthalazine moiety. Similarly, our strategy in this research depends on the interconnection between some sulfa drugs and certain phthalazin-1(2H)-one scaffolds in an attempt to enhance their antibacterial activity. This approach was achieved through the combination of 4-substituted phthalazin-1(2H)-ones 9a, b or 14a, b with sulfanilamide 1a, sulfathiazole 1b or sulfadiazine 1c through amide linkers 6a, b to produce the target compounds 10a-d and 15a-e, respectively. The antibacterial activity of the newly synthesized compounds showed that all tested compounds have antibacterial activity higher than that of their reference sulfa drugs 1a-c. Compound 10c represented the highest antibacterial activity against Gram-positive bacteria Streptococcus pneumonia and Staphylococcus aureus with MIC = 0.39 mu mol/mL. Moreover, compound 10d displayed excellent antibacterial activity against Gram-negative bacteria Escherichia coli and Salmonella Lyphimurium with MIC = 0.39 and 0.78 mu mol/mL, respectively.

Synthesis of new, vital and pharmacologically important bis phthalazine-triones using an efficient magnetic nanocatalyst and their HF and NBO investigation

One-pot pseudo five-component synthesis of some new, vital and pharmaceutically important bis 1H-Indazolo [1,2-b]phthalazine-triones has been considered in presence of prepared NiFe2O4@TiO2-DEA-OSO3H nanostructure as an efficient magnetic nanocatalyst. The synthesized compounds can be good candidates to have diverse biological potency and efficacy. The geometry, electronic structure, natural bond orbitals (NBO) and molecular electrostatic potential (MEP) surface analysis were carried out for some bis 1H-Indazolo [1,2-b]phthalazine-triones using HF/3-21G computational method. The theoretical studies revealed the existense of intramoleculare hydrogen bonds and high HOMO-LUMO energy gap for the products structures. Some advantages of this protocol are high yields, short reaction times, simple purification, and environmentally mild reaction conditions. Furthermore, the catalyst was reused at least six times without substantial loss of catalytic activity. (C) 2019 Elsevier B.V. All rights reserved.

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 122-03-2, in my other articles.

Montmorillonite K-10 Supported 11-molybdo-1-vanadophosphoric Acid (H4PMo11V1O40/K-10) Catalysts for Environmentally Benign Synthesis of 2H-indazolo[2,1-b]phthalazine-triones Under Solvent-free Condition

A series of 11-molybdo-1-vanadophosphoric acid supported on montmorillonite K-10 catalysts were prepared and characterized by FT-IR spectroscopy, thermal analysis, XRD, BET and SEM analysis techniques. Characterization data reveals the chemical immobilization of H4PMo11V1O40 catalyst on the montmorillonite K-10 support. The catalytic performance of synthesized catalysts was investigated for the synthesis of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione derivatives by one-pot three-component reaction of phthalhydrazide, dimedone and aromatic aldehydes under solvent-free conditions. Among different catalysts, 20% H4PMo11V1O40 supported on to montmorillonite K-10 showed the highest catalytic activity. Effect of reaction parameters such as catalyst loading, temperature and the nature of substituents on the aromatic ring of aldehydes were also evaluated. The protocol developed using H4PMo11V1O40/K-10 has several distinct advantages such as operational simplicity, short reaction time, high yield, reusable catalyst and preclusion of toxic solvent.

Synthesis, structural and magnetic characterization of oxalate copper(II) complexes of phthalazine, 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine and 6,7-dimethyl-2,3-di(2-pyridyl)quinoxaline. Supramolecular architectures stabilized by hydrogen bonding

The paper presents a combined experimental and computational study for three oxalate copper(II) complexes [Cu(ptz)(2)(C2O4)(H2O)center dot 1.5H(2)O (1), [Cu(dppt)(C2O4)(H2O)]center dot H2O.MeOH (2) and [Cu(dmdpq)(C2O4)(- H2O)]center dot 5H(2)O (3) (ptz = phthalazine, dppt = 3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine and dmdpq = 6,7-dimethyl-2,3-di(2-pyridyl)quinoxaline). The compounds have been studied by IR, UV-Vis spectroscopy and single crystal X-ray analysis. Due to the presence of coordinated water molecules and oxalate groups together with the lattice solvent molecules (water and methanol) their crystal structures are dominated by the hydrogen-bonding interactions that give rise to the supramolecular architectures. To elucidate the structural and spectroscopic properties of[Cu(ptz)(2)(C2O4)(H2O)], [Cu(dppt)(C2O4)(H2O)] and [Cu(dmdpq)(C2O4)(H2O)], calculations at DFT, TDDFT level were undertaken. Magnetic studies of all complexes under study showed paramagnetic behavior with large orbital magnetic contribution. (c) 2013 Elsevier Ltd. All rights reserved.

Chemiluminescence of a cyclometallated iridium(III) complex and its application in the detection of cysteine

Chemiluminescence (CL) of a cyclometallated iridium (III) complex {tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium(III)} in the presence of potassium permanganate and oxalic acid is reported for the first time. Cysteine exhibits sufficient enhancing effect on the CL generated from the cyclometallated iridium(III) complex, which make it possible for the sensitive detection of cysteine using a flow-injectionchemiluminescence (FICL) method. The optimum conditions for the chemiluminescence emission were investigated. Under the optimal condition, the linear range for the determination of cysteine was 1.0?x?1095.0?x?106?mol/L with a detection limit of 6.9?x?1010?mol/L. A relative standard deviation of 1.6% was obtained for eight replicate determinations. The mechanisms of CL are proposed and the emitting species was identified as the metal-to-ligand charge-transfer (MLCT) excited states of the iridium complex.
