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?

For further development of successors of Agomelatine through modulation of its pharmacokinetic properties, we report herein the design, synthesis and pharmacological results of a new family of melatonin receptor ligands. Issued from the introduction of quinazoline and phthalazine scaffolds carrying an ethyl amide lateral chain and a methoxy group as bioisosteric ligands analogues of previously developed Agomelatine. The biological activity of the prepared analogues was compared with that of Agomelatine. Quinazoline and phthalazine rings proved to be a versatile scaffold for easy feasible MT1 and MT2 ligands. Potent agonists with sub-micromolar binding affinity were obtained. However, the presence of two nitrogen atoms resulted in compounds with lower affinity for both MT1 and MT2, in comparison with the parent compound, balanced by the exhibition of good pharmacokinetic properties.

We report an air-stable bisboron complex as an efficient catalyst for the inverse electron-demand Diels-Alder (IEDDA) reaction of 1,2-diazine as well as 1,2,4,5-tetrazine. Its stability towards air and moisture was demonstrated by NMR studies enabling its application in organic transformations without glovebox. A one-pot procedure for its synthesis was developed starting from 1,2-bis(trimethylsilyl) benzene greatly enhancing its practicality. Comparative reactions were carried out to evaluate its catalytic activity in IEDDA reactions of diazine including phthalazine as well as 1,2,4,5-tetrazine.

Binuclear complexes of copper(II) with 1′-phthalazinylhydrazones of substituted salicylic aldehydes have been prepared and studied. Antiferromagnetic exchange interaction between copper(II) ions has been revealed in all the complexes. Taking advantage of quantum-chemical simulation, we have investigated the influence of the complexes structural isomerism on the character of the exchange interaction between the paramagnetic centers. X-ray absorbance spectroscopy afforded the structural parameters of coordination spheres of copper(II) ions; it has been demonstrated that dimerization occurred via the nitrogen atoms of phthalazine fragments.

PbO nanoparticles were explored as a highly efficient, simple, cheap, and recyclable catalyst for the fast synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives by means of a one-pot three-component reaction of phthalhydrazide, aromatic aldehyde, and malononitrile under solvent-free conditions at 80 A degrees C. Furthermore, nanosized PbO was prepared by the two conventional methods of planetary ball milling and dispersion of commercial PbO in n-octane, and their catalytic performances were compared with the commercial bulk PbO. The prepared nano-PbO via ball milling was described by SEM, TEM, XRD, EDX, and FT-IR spectroscopy. The present protocol conveyed major proficiencies such as the use of a reasonable and readily available catalyst, simple work-up and purification of products by nonchromatographic strategy, low reaction times, and enhanced yields under relatively environmental benign conditions. The heterogeneous catalyst was appropriately recyclable and could be reused for several times without loss of activity.

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.
