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.

Three novel sultone based Bronsted acidic ionic liquids are introduced. These ionic liquids were prepared in three similar two-steps reactions. The ring opening of 1,4-butane sultone was performed using 1,4-dimethyl piperazine or 1,10-phenantroline as nitrogen nucleophile sources to obtain zwitterions and then followed by acidification by treatment with perchloric acid to give the introduced ionic liquids. FTIR, (HNMR)-H-1, C-13-NMR, TGA and CHNS analysis techniques were used for the characterization of these ionic liquids. These ionic liquids are completely water soluble and have good thermal stability. Their catalytic efficiency was checked for the preparation of polycyclic 2H-indazolo[2,1-b]phthalazine-trione compounds. Small amount (3-7 mmol%) of the prepared acidic ionic liquid catalysts is required and targeted products are obtained in short times (6-25 min) at high yields (86-96%). Moreover, the introduced acidic ionic liquids are completely green, environmental benign and task specific and simply recoverable up to six consecutive runs without significant decrease in their catalytic.

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.

Facile synthesis of multi-functional 1,3,4-thiadiazine derivatives bearing phthalazine, pyridazine, and pyrido-pyridazine moieties

A series of novel, multifunctional 1,3,4-thiadiazine derivatives bearing phthalazines, pyridazines and pyrido-pyridazines (9-13) have been synthesized via the multicomponent reaction of (3-(2-bromo-2-[2-chloropyrimidin-4-yl]acetyl)-2-chlorophenyl)-2,6-dichloro benzene-sulfonamide with thiocarbohydrazide and various anhydrides. The reactions were performed by refluxing the components in mixed ethanol/acetic acid to afford the corresponding products in good to excellent yields. All the synthesized compounds were characterized by analytical and spectral studies. The developed method features short reaction time, simple work-up without chromatographic separation, and a broad range of substrate applicability.

Silver(I) complexes with quinazoline and phthalazine: synthesis, structural characterization and evaluation of biological activities

New silver.I) complexes with quinazoline (qz) and phthalazine (phtz), [Ag(NO3)(qz)](n) (1) and {[Ag(CH3CN)](2)(mu-phtz)(2)}[BF4](2) (2), have been synthesized and structurally characterized by using different spectroscopic and single-crystal X-ray diffraction techniques. The obtained results revealed that the reaction of AgNO3 with qz at room temperature in a 2 : 1 molar ratio led to the formation of the polynuclear complex 1. However, the reaction of AgBF4 with phtz under the same experimental conditions resulted in the formation of the dinuclear complex 2. The solution behaviour and air/light stability of these silver.I) complexes have been investigated. The complexes 1 and 2, along with the silver.I) salts used for their synthesis, were evaluated by in vitro antimicrobial studies against a panel of microbial strains that lead to many skin and soft tissue, respiratory, wound, and nosocomial infections. The obtained results indicate that all tested silver(I) compounds have good antibacterial activity with MIC values in the range from 1.5 to 15.6 mu g mL(-1) against the investigated strains. On the other hand, their antifungal activity against Candida albicans was moderate. In order to determine the therapeutic potential of 1 and 2, their antiproliferative effect on the normal human lung fibroblast cell line MRC5, hemolytic effect on red blood cells and embryotoxicity on zebrafish (Danio rerio) have also been evaluated.

Thermodynamic and Kinetic Studies of the Radical Scavenging Behavior of Hydralazine and Dihydralazine: Theoretical Insights

Hydralazine (HZ) and dihydralazine (DHZ) are phthalazine derivatives substituted at position 1 (HZ) or positions 1 and 4 (DHZ) by a hydrazinyl substituent. These compounds are widely used for treating hypertension and heart failure, essentially acting as vasodilators on the arteries and arterioles. In this study, the antioxidant activity of HZ and DHZ in the gas phase and in physiological environments was investigated by thermodynamic and kinetic calculations. It was found that the HOO center dot radical scavenging activity of these compounds follows the formal hydrogen transfer (FHT) mechanism. The H abstraction of the N9-H bond plays a deciding role in the HOO center dot radical scavenging of HZ-1 and DHZ-I, whereas the HOO center dot radical scavenging activities of HZ-2 and DHZ-2 are defined by the dissociation of the N10-H and Nil-H bonds, respectively. The rate constants for the HOO center dot radical scavenging of the HZ and DHZ in the gas phase are in the range of 9.64 x 10(6) to 4.52 x 10(8) M-1 s(-1), whereas in aqueous solutions and the lipid medium they are in the range of 2.62 X 10(4) to 5.13 x 10(7) M-1 s(-1) and 5.75 x 10(4) to 6.66 x 10(6) M-1 s(-1), respectively. The HOO center dot radical scavenging of DHZ-1 and DHZ-2 is thus faster than that of the reference antioxidant compound Trolox in all the studied environments. Consistently, DHZs are not only vasodilators but also potent antioxidants.

Oxidative ring cleavage of 2,3-dihydrophthalazine-1,4-dione in aqueous and non-aqueous solutions: Electrochemical and kinetic studies

Electrochemical oxidation of 2,3-dihydrophthalazine-1,4-dione (DHP) has been investigated in aqueous and some amphiprotic and aprotic non-aqueous solvents by cyclic voltammetric and controlled-potential coulometric techniques. Our data shows that electrochemically generated phthalazine-1,4-dione (PTD) in water and amphiprotic non-aqueous solvents participates in an oxidative ring cleavage (ORC) reaction to form phthalic acid. The rate of this reaction is dependent. On autoprotolysis constant (K-SH) and basicity of the solvent. Therefore, in the aprotic non-aqueous solvents such as acetonitrile and DMSO, the rate of ORC is too slow to be observed on the time-scale of cyclic voltammetry.
