Abstract In this work, we used the design strategy “doped nonpolar polymers” and synthesized polyurethane elastomers (PUEs) by doping with highly polar aromatic molecules such as benzoic acid (BA), 4(para)-nitro-benzoic (PNBA), 3, 5-di-nitro-benzoic (3, 5-DNBA) using solution casting method. The effect of each molecule in three different weight percentages 2%, 4%, 6% on electrical thermo-mechan...

Nitro compounds are an important class of organic molecules with broad application in synthesis, medicinal chemistry, and materials science. Among the variety methodologies available for their direct oxidation primary amines represents attractive alternative route. Efforts towards development oxidative procedures synthesis nitro derivatives have spanned over past decades, leading to a wide prot...

Background & Aims of the Study: One of the most carcinogenic and toxic pollutants is p-Nitro Cresol. In this study, the degradation and mineralization of p-Nitro Cresol in aqueous solution were investigated by Fenton process in a batch reactor. Materials & Methods: This study is an experimental research on a laboratory scale. The study executed on synthetic wastewater hav...

A series of new 2-(phenylthio) benzoylaryl hydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. The chemical structures of the compounds were elucidated by FT-IR, 1H-NMR and Mass spectra. All newly synthesized compounds were evaluated for their antimycobacterial activities against Mycobacterium tuberculosis H37Rv using the microplate alamar blu...

Hydrolytic lignin is a large-tonnage waste product of ethyl alcohol production and renewable resource. The structure characterized by the presence large number hydroxyl groups, which provides value as raw material for synthesis in polymer chemistry. But due to their low chemical stability dilute alkalis, acids solvents, lignins are little use wide practical use. introduction additional function...

A series of five-membered heterocyclic rings were synthesized by the reaction between benzoyl chloride and various chlolro-nitro-benzoyl chlorides and semi carbazide to form (C1-C7) compounds and was tested for their anti-inflammatory activity determined by rat-paw-oedema method. All the synthesis compounds have been characterized by 1HNMR, IR and Mass spectral data. The compounds were purified...

Nitro catechols via 2 hydroxyl group and a nitro group have a wide range of functions including reagents form stable complexes with more than 40 elements in the fields of analytical chemistry, biochemistry, coordination chemistry, environmental chemistry, atrium exploration, organic chemistry, pharmacy, etc. Moreover, the nitro to amine recovery has a potential function in different fields. In ...

BACKGROUND Chronic treatment with the dietary flavonoid quercetin is known to lower blood pressure and restore endothelial dysfunction in animal models of hypertension. This study investigated the direct effects of quercetin on vascular response in chronic 2-kidney, 1-clip (2K1C) renal hypertensive rats. The effects of antioxidant vitamin ascorbic acid on the vasoreactivity were also examined. ...

The purpose of this study was to test the hypothesis that endothelium-dependent dilation is impaired in soleus resistance arteries from hindlimb-unweighted (HLU) rats. Male Sprague-Dawley rats (300-350 g) were exposed to HLU (n = 14) or weight-bearing control (Con, n = 14) conditions for 14 days. After the 14-day treatment period, soleus first-order (1A) arterioles were isolated and cannulated ...
