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.

Experimental and theoretical study on one-pot, three-component route to 2H-indazolo[2,1-b]phthalazine-triones catalyzed by nano-alumina sulforic acid

A simple, efficient, and high yielding one-pot protocol for the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives has been developed by three-component coupling of phthalhydrazide, dimedone and some aromatic aldehydes in ecofriendly neat conditions promoted by nano-gamma-alumina sulforic acid. This protocol avoids the use of expensive catalysts, toxic solvents and chromatographic separation. Also the proposed protocol was extended to the linear beta-diketone (acetylaceton) instead of cyclic diketone (dimedone). The generality and functional tolerance of this convergent and environmentally benign method is demonstrated. The nature of each step of the suggested mechanism for this condensation reaction is also identified through Density Functional Theory (DFT) calculations using B3LYP/6-31G** level of theory. It is shown that the first step is charge controlled; whereas the second one is controlled by frontier molecular orbitals. The H-1 and C-13 chemical shift values together with the structural parameters of the title compound have been also computed and the scaled values have been compared with the corresponding experimental NMR and X-ray spectra. As a result, the calculated spectroscopic data and optimized geometry show a good agreement with the experimental results. (C) 2012 Elsevier B.V. All rights reserved.

Efficient synthesis of selected phthalazine derivatives

Four phthalazine derivatives have been prepared from substituted 2-bromobenzaldehyde acetals by a sequence involving: (1) lithiation and formylation; (2) deprotection; and (3) condensative cyclization with hydrazine. Two additional phthalazines were prepared by a similar sequence following direct lithiation of benzaldehyde acetals substituted by anion-stabilizing groups at C3. These syntheses can be conveniently carried out to give phthalazines in overall yields of 40-70%.

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 1571-08-0, in my other articles.

Anticancer activity assessment of two novel binuclear platinum (II) complexes

In the current study, two binuclear Pt (II) complexes, containing cis, cis-[Me2Pt (mu-NN) (mu-dppm) PtMe2] (1), and cis,cis-[Me2Pt(mu-NN)(mu dppm,) Pt((CH2)(4))] (2) in which NN = phthalazine and dppm = bis (diphenylphosphino) methane were evaluated for their anticancer activities and DNA/purine nucleotide binding properties. These Pt (II) complexes, with the non-classical structures, demonstrated a significant anticancer activity against Jurkat and MCF-7 cancer cell lines. The results of ethidium bromide/acridine orange staining and Caspase-III activity suggest that these complexes were capable to stimulate an apoptotic mechanism of cell death in the cancer cells. Using different biophysical techniques and docking simulation analysis, we indicated that these complexes were also capable to interact efficiently with DNA via a non-intercalative mechanism. According to our results, substitution of cyclopentane (in complex 2) with two methyl groups (in complex 1) results in significant improvement of the complex ability to interact with DNA and subsequently to induce the anticancer activity. Overall, these binuclear Pt (II) complexes are promising group of the non-classical potential anticancer agents which can be considered as molecular templates in designing of highly efficient platinum anticancer drugs.

ONE-POT FOUR COMPONENT REACTION FOR THE SYNTHESIS OF 1-(1H-INDOL-2-YL)-1H-PYRAZOLO [1,2-b]PHTHALAZINE-5,10-DIONE DERIVATIVES BY SELF-CATALYSIS

In this, we performed a four component domino reaction of phthaloyl dichloride, hydrazine hydrate, indole-3-carboxaldehydes and malononitrile/ethyl cyanoacetate to form 1-(1H-indol-2-yl)-1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives by in situ generation of HCl as catalyst in refluxing ethanol for 1 h in good yields. This four component domino reaction transformation presumably proceeds via addition/dehydrohalogenation/condensation/cyclization of reactions. The material was thoroughly characterized at various stages of its formation by means of FTIR, NMR spectroscopic and Mass spectrometric analysis and is confirmed to be the derivative of 1-(1H-indo1-2-yl)-1H-pyrazolo [1,2-b]phthalazine-5,10-dione.
