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.

Preparation of a poly(phthalazine ether sulfone ketone) membrane with propanedioic acid as an additive and the prediction of its structure

In this study, propanedioic acid was investigated as a potential additive in poly(phthalazine ether sulfone ketone) (PPESK)/N-methyl-2-pyrrolidone solutions. Compared with poly(ethylene glycol) with a molecular weight of 1000 and Tween 80 as additives, different phenomena were observed: (1) both fingerlike and spongelike structures of asymmetric ultrafiltration membranes were induced by rapid gelation, and (2) a spongelike structure membrane with a high pure water flux was obtained under a high gelation rate. Moreover, the PPESK membrane formation process was recorded with a recently developed optical microscopy (OM)-charge-coupled device (CCD) camera experimental system. The predicted membrane structure with an OM-CCD system gave good correspondence with the final membrane structure and performance, as detected by scanning electron microscopy.

A Practical and Direct Comparison of Intrinsic Metabolic Clearance of Several Non-CYP Enzyme Substrates in Freshly Isolated and Cryopreserved Hepatocytes

Human hepatocytes are a physiologically relevant tool useful in evaluating liver-related pharmacokinetics, including non-cytochrome P-450 (CYP) metabolism, due to their broad spectrum of metabolic enzyme activity. To verify the usefulness of human hepatocytes in evaluating non-CYP metabolism for drug discovery, we compared intrinsic clearance values (CLint) in freshly isolated and cryopreserved hepatocytes using 14 compounds primarily metabolized by non-CYP enzymes, including UDP-glucuronosyltransferase, carbonyl/aldo-keto reductase, aldehyde oxidase, flavin-containing monooxygenase, and monoamineoxidase. Cryopreservation resulted in a > 20% reduction (maximum: 50%) in CLint in 7/14 compounds (statistically significant for 5 compounds) on comparing CLint values in freshly isolated and cryopreserved hepatocytes from the same donors (n = 4). However, the number of compounds with > 20% CLint reduction decreased to 3 on comparing average of CLint values including un-matched donors (dolasetron: -27%, naltorexone: -32%, and phthalazine: -48%; statistically significant for phthalazine, n = 6-11). These findings suggest that fresh hepatocytes are useful in evaluating intact non-CYP enzyme activities. However, we must note that the reduction in CLint by cryopreservation could be rendered negligible if high-activity lots are selected for assay. We therefore recommend using cryopreserved hepatocytes for large-scale screening for non-CYP metabolism in drug discovery research considering the advantages in usability with cryopreserved hepatocytes.

An atom-efficient and environmentally friendly approach to the synthesis of 2,5-disubstituted-1,3,4-thidiazine derivatives has been developed. These compounds were synthesized by a reaction of 2-(2-bromoacetyl)benzofuran and thiocarbohydrazide with various aryl aldehydes, acetylacetones, and pthalic anhydrides in good yields. The advantages of this methodology are mild reaction conditions, easy workup procedure, clean reaction profile, shorter reaction time, and a wide range of substrate applicability.

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.

Synthesis, structural characterization, and molecular docking study of new phthalhydrazide-coumarin hybrids

A series of new phthalhydrazide-coumarin hybrids was obtained in the reaction of phthalhydrazide with corresponding bromopropoxycoumarin derivatives. These reactions were performed in the presence of Cs2CO3, in acetonitrile as solvent, and under reflux for 5 h. Obtained hybrids contain one or two coumarin scaffolds bonded to phthalhydrazide nitrogen via propoxy linker. Ten new phthalhydrazide-coumarin hybrids were obtained in moderate to good yields, and characterized with melting point, elemental analysis, IR and NMR spectroscopy, and LC-MS spectrometry. Additionally, the structures of these compounds were elucidated based on experimental and theoretical data (IR, H-1 NMR, and C-13 NMR). Excellent agreement between experimental and simulated spectra was achieved. The prediction of the potential biological activity of synthesized compounds was done using the online program PASS (Prediction of Activity Spectra for Substances). Based on the obtained results, the serotonin 2A receptor (5-HT2AR) was selected for molecular docking study. Molecular docking was also performed with commercially available drug Risperidone, and obtained results were compared with potential bioactive conformations of obtained phthalhydrazide-coumarin hybrids.

Cu@Fe3O4 MNPs as novel nanomagnetic reagents were prepared to investigate their catalytic behavior in the preparation of tetrahydrobenzimidazo[2,1-b]quinazolin-1(2H)-ones, as important biologically active compounds. Then, characterization of the synthesized nanoparticles was performed using different methods including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) analysis, thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), energy dispersive X-ray (EDX), and scanning electron microscopy (SEM). All reactions were performed with small amounts of the Cu@Fe3O4 MNPs under solvent-free conditions. After completion of the reaction, because of the magnetic nature of the nanocatalyst, they could be simply separated with an external magnet and easily reused with no considerable decrease in the catalytic behavior even after seven runs.
