A new method to introduce iminodiacetic acid (IDA) onto polyethersulfone (PES) matrix through chlorosulfonation was described in this work, and the prepared PES‐IDA was used as adsorbent for the removal of metal ions from aqueous solutions. Chlorosulfonic groups (SO2Cl) were introduced onto PE...
An attempt has been made to prepare a new blend polymer electrolytes (BPEs) based on PVdF-co-HFP and PVAc doped with Mg (ClO4)2 by using the solvent-casting technique. The physicochemical properties of the as prepared polymer electrolytes were characterized by XRD, FTIR, SEM, TG/DTA, linear swee...
Thermal decomposition characteristic of calcium magnesium acetate (CMA), calcium acetate (CA) and magnesium acetate (MA) are investigated through thermogravimetric (TG) analysis at the heating rates of 5Kmin −1 , 7.5Kmin −1 , 10Kmin −1 and 15Kmin −1 . After dehydr...
A new two‐dimensional (2D) magnesium acetate, Mg7(OH)2(OAc)12(H2O)4·4H2O (1), was obtained from zero‐dimensional (0D) magnesium acetate tetrahydrate as a single source of the metal and carboxylate ions with nonpolar benzene as the solvent. Compound 1 exhibits an unusual 2D inorganic [Mg7(OH)2...
Proteins are not considered as true antioxidants but are known to protect antioxidants from oxidation in various antioxidant activity assays. This study aims to investigate the contribution of proteins, especially thiol-containing proteins, to the observed overall antioxidant capacity measured b...
Cupric oxide mesoporous nanosheets (CuO‐MNS) were successfully synthesized via a novel cupric acetate self‐induced, stabilized route. X‐ray diffraction analysis showed that CuO‐MNS are well crystallized and present a pure monoclinic phase. Transmission electron microscopy (TEM) exhibited tha...
A modification of the Wacker oxidation of terminal olefins to methyl ketones using substoichiometric amounts of Cu(OAc) 2 as a redox shuttle reagent is described. The modified procedure is generally high yielding despite reduced levels of copper salt and convenient. Importantly, in a pro...
2‐Arylethylbut‐3‐en‐1‐ol is found to undergo smooth Prins cascade reactions with various aldehydes in the presence of Sc(OTf)3 (10 mol‐%) and a stoichiometric amount of TsOH to afford the corresponding trans‐fused hexahydro‐1H‐benzo[f]isochromenes in good yields with excellent selectivi...
In this contribution, the first direct and efficient functionalization of the preformed 2‐phenyltetrahydropyran (2‐PhTHP) nucleus by electrophilic interception of the corresponding α‐lithiated derivative by employing sBuLi as the base and THF as the solvent at –78 °C was explored. The pres...
The protozoan parasites Trypanosoma brucei, Trypanosoma cruzi and Leishmania spp. are responsible for the severely debilitating neglected Tropical diseases of African sleeping sickness, Chagas disease and leishmaniasis, respectively. As part of our ongoing programme exploring the potential of si...
The title compound, a salt of C13H20O2 2+ 2Cl− 0.5 H2O, (I), crystallizes in the monoclinic space group C 2/c with unit cell parameters a = 34.091(4) Å, b = 7.2312(4) Å, c = 12.5827(5) Å, β = 96.870(6)°, Z = 8. The dihedral angle between the mean plane of the benzyl ring and the piperazin-1-yl...
Cetirizine is a piperazine-derived second-generation antihistaminic drug recommended for treatment of pruritus associated with atopic dermatitis. The present investigation encompasses development of a nanosized novel elastic vesicle-based topical formulation of cetirizine dihydrochloride using c...
The effect of anthelmintic treatment of pigs on the embryonation and infectivity of Ascaris suum eggs isolated from expelled worms was investigated. Four groups of two naturally infected pigs were dosed with albendazole, pyrantel pamoate, ivermectin or piperazine dihydrochloride, respectively. F...
The reaction of Zn(NO 3 ) 2 .6H 2 O with PPz hexahydrate (PPz=piperazine) and NH 4 SCN in CH 3 OH afforded the complex [Zn(NCS) 2 (PPz)] n (1). The reaction of CoCl 2 .6H 2 O with PPz in CH 3 OH afforded the complex ...
Single crystals of (C4H12N2)[Ni(H2O)6](SeO4)2 were synthesized by the slow evaporation method from an aqueous solution of piperazine hexahydrate, nickel(II) carbonate, and selenic acid. This hybrid compound crystallizes in the monoclinic system, space group P21/c, with the following unit cell pa...
Ciprofloxacin hexahydrate has been prepared and its crystal structure has been determined by X-ray crystallography. The molecule is in the zwitterionic form in solid state, the carboxylic proton being present at terminal piperazine nitrogen atom (N(74)) which is in contrast to the previously re...
ε-Amino caproic acid (EACA), a lysine analog that inhibits the activity of plasmin, was added to Nycomed (TC-S) fibrin bandages, and the bandages were tested for hemostatic efficacy in a swine femoral artery bleeding model. The blood loss using the bandage with EACA (TC-S+EACA; 728.8±132 g, n=...
The objective of this study was to identify and quantify fermentation end‐products, detected with chromatographic techniques, that were negatively related to intake of grass silage by cattle. Further, the aim was to verify the intake‐depressing effect of these compounds in a feeding trial. A s...
