The two faces of aldehyde oxidase: Oxidative and reductive transformations of 5-nitroquinoline

Aldehyde oxidase (AOX) is a cytosolic enzyme responsible for the metabolism of some drugs and drug candidates. AOX catalyzes the oxidative hydroxylation of substrates including several aliphatic and aromatic aldehydes, and nitrogen-containing heterocyclic compounds. AOX is also reported to catalyze the reductive metabolism of nitro-compounds, N-oxides, sulfoxides, isoxazoles, isothiazoles, nitrite and hydroxamic acids. These reductive transformations are not well understood and are generally believed to only occur at low oxygen concentrations. In this study, we used 5-nitroquinoline (5NQ) as a substrate to further understand both the oxidative and the reductive transformations catalyzed by AOX. In vitro reaction of 5NQ with AOX under aerobic conditions generated the oxidized (2-oxo-5-nitroquinoline, 2-oxo-5NQ), the reduced (5-aminoquinoline, 5AQ) and the oxidized/reduced (2-oxo-5-aminoquinoline, 2-oxo-5AQ) metabolites. Interestingly, in human liver cytosol, co-incubation of 5NQ and known AOX oxidative substrates DACA and phthalazine significantly increased the yield of the reduced metabolite, while oxidized metabolites production decreased. These data indicate that 5NQ can be reduced at atmospheric oxygen concentrations and that the reductive transformation occurs at a second site that is kinetically distinct from the oxidative site.

Phosphotungstic acid supported on SiO2@NHPhNH2 functionalized nanoparticles of MnFe2O4 as a recyclable catalyst for the preparation of tetrahydrobenzo[b]pyran and indazolo[2,1-b]phthalazine-triones

MnFe2O4@SiO2@NHPhNH2-phosphotungstic acid was synthesized by the reaction of diamine-modified silica coated manganese ferrite nanoparticles with H3PW12O40, the Keggin-type heteropoly acid. This is the first time that H3PW12O40 supported on diamine functionalized MnFe2O4 nanoparticles has been reported. The synthesized catalyst was characterized by various techniques, including Fourier Transform Infrared Spectroscopy (FTIR), Transmission electron-microscopy (TEM), X-ray Powder Diffraction (XRD), Scanning Electron Microscope (SEM), Energy Dispersive X-ray Spectroscopy (EDX), Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), Thermogravimetric Analysis (TGA), and Vibrating Sample Magnetometer (VSM). The synthesized nanoparticle was examined as the heterogenous nanocatalyst for the synthesis of tetrahydrobenzo[b]-pyran derivatives and 2H-indazolo-[2,1-b]-phthalazine-triones under the solvent-free heating or ultrasonic irradiation conditions. This method offers several advantages including high yield, low reaction times, and the simple work up procedure due to the presence of the magnetic nanoparticles in this catalyst, so that, it can be easily recovered and reused for at least six successive times without the loss of its high catalytic activity, suggesting its great Potential for industrial applications.

A DFT Study of Electronic Structures and Relative Stabilities of Isomeric n,m-Diazaphenanthrenes

In this study, the structural properties, energetic data, and classification of the chemical properties of n,m-diazaphenanthrine derivatives were studied by a density functional theory (DFT) method. The important and proper indices were applied in this investigation. The structures, electronic properties, and chemical reactivities of 25 isomeric n,m-diazaphenanthrenes were studied by a B3LYP/6?31+G(d) method/basis set. All the optimized geometries of these isomers kept good planarity. The structural properties such as bond lengths and dipole moments of these isomers were calculated. The energies of frontier orbitals (HOMO and LUMO) are used to determine several chemical reactivity parameters as a measure of their relative stabilities. These include total energy (E), ionization potential (I), electron affinity (A), chemical hardness (?), chemical softness (S), electronic chemical potentials (?), and electrophilicity (?). Based on these calculations, the heats of formation (?H?(f)) for all the n,m-diazaphenanthrine derivatives are predicted. Benzo[h]quinazoline (P-13) and benzo[f]cinnoline (P-34) are calculated to be the most stable and the least stable isomers, respectively. 1,10-Phenanthroline (P-110) possesses the minimum electrophilicity, while benzo[c]cinnoline (P-56) is calculated to have the highest electrophilicity among the isomeric structures. The largest and smallest dipole moments are calculated for benzo[f]phthalazine (P-23) and 3,8-phenanthroline (P-38), respectively. Linear relationships between the calculated E-LUMO (in eV) values and electrophilicity (?) of the isomeric n,m-diazaphenanthrenes were observed.

A new natural based ionic liquid 3-sulfonic acid 1-imidazolopyridinium hydrogen sulfate as an efficient catalyst for the preparation of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-triones

A novel Bronsted acidic ionic liquid 3-sulfonic acid 1-imidazolopyridinium hydrogen sulfate [Simp]HSO4 was synthesized via the reaction of caffeine with chlorosulfonic acid and was characterized by studying FT-IR, H-1 NMR, C-13 NMR, UV-Vis, and fluorescence spectra. Then, the prepared ionic liquid was utilized as an efficient catalyst for the preparation of 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-trione derivatives through one-pot, multi-component condensation of aldehydes, phthalhydrazide, and dimedone under solvent free conditions. The high Bronsted acidic function of this catalyst originates principally from the dual hydrogen bonding abilities of the SO3H group. (C) 2015 Elsevier B.V. All rights reserved.

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.

Imidazole-containing phthalazine derivatives inhibit Fe-SOD performance in Leishmania species and are active in vitro against visceral and mucosal leishmaniasis

The in vitro leishmanicidal activity of a series of imidazole-containing phthalazine derivatives 1-4 was tested on Leishmania infantum, Leishmania braziliensis and Leishmania donovani parasites, and their cytotoxicity on J774.2 macrophage cells was also measured. All compounds tested showed selectivity indexes higher than that of the reference drug glucantime for the three Leishmania species, and the less bulky monoalkylamino substituted derivatives 2 and 4 were clearly more effective than their bisalkylamino substituted counterparts 1 and 3. Both infection rate measures and ultrastructural alterations studies confirmed that 2 and 4 were highly leishmanicidal and induced extensive parasite cell damage. Modifications to the excretion products of parasites treated with 2 and 4 were also consistent with substantial cytoplasmic alterations. On the other hand, the most active compounds 2 and 4 were potent inhibitors of iron superoxide dismutase enzyme (Fe-SOD) in the three species considered, whereas their impact on human CuZn-SOD was low. Molecular modelling suggests that 2 and 4 could deactivate Fe-SOD due to a sterically favoured enhanced ability to interact with the H-bonding net that supports the antioxidant features of the enzyme.
