To develop a phosphate adsorbent in powder form that is easily separated from water, we prepared magnetic spinel zinc ferrite using a facile solvothermal technique. Characterization of zinc ferrite was done by VSM, XRD, TEM, and FTIR measurements. We found that zinc ferrite crystallized as a cub...

A new, highly selective turn-on fluorescent chemosensor based on 2-(2′-tosylamidophenyl)thiazole (1) for the detection of zinc and phosphate ions in ethanol was synthesized and characterized. Sensor 1 showed a high selectivity for zinc compared to other cations and sequentially detected hydroge...

The structures of several azo-benzoic acids, 4-[((E)-1-{2-hydroxy-5-[(E)-2-(aryl)-1-diazenyl]phenyl}methylidene)amino]benzoic acid along with their precursors 2-hydroxy-5-[(E)-(aryldiazenyl)]benzaldehydes were confirmed using 1H, 13C NMR, UV–VIS and IR spectroscopic techniques. UV–VIS absorpti...

A series of new N-substituted anthranilic acid dimer derivatives having a C-terminal Phe residue was synthesized and evaluated for their affinity for CCK receptors. These compounds resulted from a blended approach based firstly on the use of an alternative substructure embedded within asperlicin...

To cope with developing pest resistance and ecological problems associated with conventional insecticides and to search for potent insecticides targeting at ryanodine receptor (RyR), a series of novel anthranilic diamides containing N-substitued nitrophenylpyrazole were designed and synthesized....

An efficient iodine-mediated electrophilic tandem cyclization of substituted 2-alkynylbenzaldehydes with anthranilic acids under basic medium leading to iodo-1,2-dihydroisoquinoline-fused benzoxazinones is presented. Success of the protocol for the reaction of substituted 2-alkynylbenzaldehydes ...

Structure–affinity relationship (SAR) and structure–kinetics relationship (SKR) studies were combined to investigate a series of biphenyl anthranilic acid agonists for the HCA2 receptor. In total, 27 compounds were synthesized and twelve of them showed higher affinity than nicotinic acid. Two ...

Highly porous and interconnected methacrylate-based porous materials were prepared by photopolymerisation of the continuous phase of high internal phase emulsion (HIPE) templates. The rapid cure afforded by photopolymerisation effectively ‘locks’ the emulsion morphology prior to emulsion desta...

In this work, poly(carboxybetaine methacrylate) as an extremely hydrophilic polymer was modified on superparamagnetic Fe3O4 nanoparticles (pCB-Fe3O4), which were employed to immobilize porcine pancreatic lipase. The properties of immobilized lipase were investigated in comparison with the free e...

This article reports on the synthesis of a thermosensitive hydrophilic diblock copolymer with the thermosensitive block containing a catalytic 4-N,N-dialkylaminopyridine and the study of the effect of thermo-induced micellization on its catalytic activity in the hydrolysis of p-nitrophenyl aceta...

Our recent work proved that Candida rugosa lipase (CRL) covalently bonded on poly(glycidyl methacrylate) grafted silica nanoparticles (S-pGMA) showed hyperactivation while on a zwitterionic polymer grafted silica exhibited higher stability. Inspired by the research, we have herein proposed to mo...

We compare the photorefractivity in Poly(vinylcarbazole) (PVK)-based composites doped with N-(4-nitrophenyl)-(l)-prolinol (NPP) and its derivative, N-(4-nitrophenyl)pyrrolidine-2-methyl methacrylate (NPPMMA) at the ratio of PVK:NPP (or NPPMMA):2,4,7-trinitro-9-fluorenone: N-ethylcarbazole=35:50:...

In the present study, third-order nonlinear optical properties of three chalcone derivatives, (2E)-3-(4-methoxyphenyl)-1-(4-nitrophenyl)prop-2-en-1-one (MNC), (2E)-3-(4-methylphenyl)-1-(3-nitrophenyl)prop-2-en-1-one (ML3NC) and (2E)-3-(3,4-dimethoxyphenyl)-1-(4-methoxyphenyl)prop-2-en-1-one (DMM...

Categories and read-across are essential tools for supplying information for assessments of endpoints without data while minimizing animal testing. This study is based on the guidance of ECHA in its Read-Across Framework (RAAF). A category of C1 – C8 alkyl methacrylate esters (methyl, ethyl, n-...

Elevated low-density-lipoprotein cholesterol (LDL-C) level is a major risk factor leading to cardiovascular diseases. Therefore, since the proprotein convertase subtilisin kexin type 9 (PCSK9) regulates LDL-C receptors, it represents the appropriate target for cholesterol-lowering gene therapy. ...

Cholesterol esterase-like (CE) activity from saliva and esterase from cariogenic bacteria hydrolyze ester linkages of dental methacrylate resins. Collagenolytic, matrix metalloproteinase-like (MMP) activities from dentin and bacteria degrade collagen in demineralized tooth dentin. Human neutroph...

ESR study of VO2+ doped trisodium citrate pentahydrate is undertaken at room temperature. The observed spectra are correlated with the available crystal structure data and are fitted to a spin Hamiltonian of orthorhombic symmetry with gx = 1.998 ± 0.001, gy = 1.992 ± 0.001, gz = 1.934 ± 0.001...

The aim of this study is to examine from a biochemical and histological perspective, whether vanadium has a protective effect on the pancreas of diabetic rats. Male, 6–6.5 months old, Swiss albino rats were divided into four groups. Group I: control (intact) animals (n = 13). Group II: control ...
