Phthalazine Derivatives Containing Imidazole Rings Behave as Fe-SOD Inhibitors and Show Remarkable Anti-T. cruzi Activity in Immunodeficient-Mouse Mode of Infection

A series of new phthalazine derivatives 1-4 containing imidazole rings were prepared. The monoalkylamino substituted. derivatives 2 and 4 were more active in vitro against T. cruzi and less toxic against Vero cells than both their disubstituted analogues and the reference drug benznidazole. Compounds 2 and 4 highly inhibited the antioxidant parasite enzyme Fe-SOD, and molecular modeling suggested that they interact with the H-bonding system of the iron atom moiety. In vivo tests on the acute phase of Chagas disease gave parasitemia inhibition values twice those of benznidazole, and a remarkable decrease in the reactivation of parasitemia was found in the chronic phase for immunodeficient mice. Glucose metabolism studies showed that compounds 1-4 did not affect the succinate pathway but originated important changes in the excretion of pyruvate metabolites. The morphological alterations found in epimastigotes treated with 1-4 confirmed extensive cytoplasm damage and a high mortality rate of parasites.

A novel chromogenic and fluorogenic chemosensor for detection of trace water in methanol

A novel receptor (E)-1-(phthalazine-4-yl)-2-(1-(pyridine-2-yl) ethylidene) hydrazine (3) was developed for the detection of trace water content present in methanol. Upon interaction of water molecule with receptor 3, there appears a significant color change from colorless to yellow green and the absorption band at 355 nm was shifted to 435 nm (i.e. bathochromic or red shift) due to selective encapsulation of water molecule at 1-(pthalazine-4-yl) hydrazine-NH and imine groups leading to tautomeric transformation in the ground state which is caused by an intramolecular proton transfer. Also, there was remarkable enhancement in fluorescence intensity of 3 in methanol upon addition of water. Thus the chemosensor 3 has been developed for chromogenic and fluorogenic investigation of water and the detection limit is 5 ppm in methanol. (C) 2015 Elsevier B.V. All rights reserved.

The electrochemical oxidation of 2,3-dihydrophthalazine-1,4-dione (1) has been studied in the presence of indole derivatives as nucleophiles in a water/acetonitrile mixture by means of cyclic voltammetry and controlled-potential coulometry. Results indicate that electrogenerated phthalazine-1,4-dione (1ox) participates in a Michael type addition reaction with indole derivatives (2 and 3) via an EC mechanism. In this work, we propose a mechanism for the electrode process.

Highly efficient red phosphorescent organic light-emitting diodes based on solution processed emissive layer

Highly efficient red phosphorescent organic polymer light-emitting diodes (PhOLEDs) were fabricated based on a solution-processed small-molecule host 4,4′-bis(N-carbazolyl)-1,1′-biphenyl (CBP) by doping an iridium complex, tris(1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine)iridium (III) (Ir(MPCPPZ)(3)). A hole blocking layer 1,3,5-tri(1-phenyl-1H-benzo[d]imidazol-2-yl)phenyl (TPBI) with a function of electron transport was thermally deposited onto the top of CBP layer. The diode with the structure of ITO/PEDOT:PSS (50 nm)/CBP:Ir(MPCPPZ)(3) (55 nm)/TPBI (30 nm)/Ba (4 nm)/Al (120 nm) showed an external quantum efficiency (QE(ext)) of 19.3% and luminous efficiency (LE) of 18.3 cd/A at a current density of 0.16 mA/cm(2), and Commission International de l’Eclairage (CIE) coordinates of (0.607, 0.375). It was suggested that the diodes using TPBI layer exhibited nearly 100% internal quantum efficiency and one order magnitude enhanced LE or QE(ext) efficiencies. (c) 2013 Elsevier B.V.

Enantioselective Halolactonizations Using Amino-Acid-Derived Phthalazine Catalysts

Amino-acid-derived phthalazine catalysts have been designed and synthesized for enantioselective halolactonization of prochiral dienoic acids. The scope of the reaction is evidenced by 17 examples of Spiro a-exo-methylene-halolactones with up to 99.8% enantiomeric excess. The resulting enantio-enriched Spiro halolactone products are found to exhibit potent antitumor effects. In addition, both antipodes of products with equally excellent enantioselevity could be obtained since a pair of enantiomeric catalysts is guaranteed.

An alpha 5 GABAA Receptor Inverse Agonist, alpha 5IA, Attenuates Amyloid Beta-Induced Neuronal Death in Mouse Hippocampal Cultures

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder for which no cognition-restoring therapies exist. Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the brain. Increasing evidence suggests a remodeling of the GABAergic system in AD, which might represent an important therapeutic target. An inverse agonist of alpha 5 subunit-containing GABAA receptors (alpha 5GABAARs), 3-(5-Methylisoxazol-3-yl)-6-[(1-methyl-1,2,3-triazol-4-yl)methyloxy]-1,2,4-triazolo[3-a]phthalazine (alpha 5IA) has cognition-enhancing properties. This study aimed to characterize the effects of alpha 5IA on amyloid beta (A beta(1-42))-induced molecular and cellular changes. Mouse primary hippocampal cultures were exposed to either A beta(1-42) alone, or alpha 5IA alone, alpha 5IA with A beta(1-42) or vehicle alone, and changes in cell viability and mRNA expression of several GABAergic signaling components were assessed. Treatment with 100 nM of alpha 5IA reduced A beta(1-42)-induced cell loss by 23.8% (p < 0.0001) after 6 h and by 17.3% after 5 days of treatment (p < 0.0001). Furthermore, we observed an A beta(1-42)-induced increase in ambient GABA levels, as well as upregulated mRNA expression of the GABAAR alpha 2,alpha 5,beta 2/3 subunits and the GABABR R1 and R2 subunits. Such changes in GABARs expression could potentially disrupt inhibitory neurotransmission and normal network activity. Treatment with alpha 5IA restored A beta(1-42)-induced changes in the expression of alpha 5GABAARs. In summary, this compound might hold neuroprotective potential and represent a new therapeutic avenue for AD. Interested yet?

Highly efficient and robust molecular ruthenium catalysts for water oxidation

Water oxidation catalysts are essential components of light-driven water splitting systems, which could convert water to H-2 driven by solar radiation (H2O + h nu -> 1/2O(2) + H-2). The oxidation of water (H2O -> 1/2O(2) + 2H(+) + 2e(-)) provides protons and electrons for the production of dihydrogen (2H(+) + 2e(-) -> H-2), a clean-burning and high-capacity energy carrier. One of the obstacles now is the lack of effective and robust water oxidation catalysts. Aiming at developing robust molecular Ru-bda (H(2)bda = 2,2′-bipyridine-6,6′-dicarboxylic acid) water oxidation catalysts, we carried out density functional theory studies, correlated the robustness of catalysts against hydration with the highest occupied molecular orbital levels of a set of ligands, and successfully directed the synthesis of robust Ru-bda water oxidation catalysts. A series of mononuclear ruthenium complexes [Ru(bda)L-2] (L = pyridazine, pyrimidine, and phthalazine) were subsequently synthesized and shown to effectively catalyze Ce-IV-driven [Ce-IV = Ce(NH4)(2()NO3)(6)] water oxidation with high oxygen production rates up to 286 s(-1) and high turnover numbers up to 55,400.
