The energy and oscillator strength calculated by time dependent density f...

SummaryNovel 1,3,4-Oxadiazoles bearing benzimidazole nucleus were designed, synthesized using 2-(2-(substituted phenoxymethyl)-1H-benzo[d]imidazol-1-yl)acetohydrazide and carbon disulfide. These newly synthesized benzimidazolyl oxadiazoles along with benzimidazolyl acetates and benzimidazolyl ac...

The title compounds 3a–l have been synthesized by the reaction of thiocarbohydrazide with substituted phenoxy acetic acid to obtained substituted 1,2,4-triazoles (1). Compound 1 was treated with various substituted aromatic aldehydes which results in 4-(substituted benzylideneamino)-5-(substitu...

Transient absorption spectrum of anisole in acetonitrile was observed by a 248-nm laser photolysis. In addition to the structured band observed at 400 nm, which was assigned to phenoxyl radical, a broad absorption band appeared at around 440 nm. The lifetime of the unknown species was not affect...

A series of 37 dicationically substituted bis(phenoxymethyl)benzene bis(phenoxymethyl)naphthalene, and bis(benzyloxy)naphthalene analogues of pentamidine was prepared and evaluated for antiprotozoal activities and cytotoxicity in in vitro. 1,3-Bis(4-amidinophenoxymethyl)benzene (1) was the most ...

The X-ray crystal structure of 2-(4,5-dihydro-5-phenoxymethyl-1,3-oxazol-2-ylamino)-7-(2-hydroxy-3-phenoxypropyl)hexahydro-2H,6H-pyrimido[6,1-b][1,3]oxazin-6-one (1), a structure of adduct formed by the reaction of 5-(phenoxymethyl)-2-amino-2-oxazoline and acrolein, has been established. The pre...

Surfactant assisted pressurized liquid extraction (PLE) with a laboratory made system was applied for the extraction of glycyrrhizin in Radix glycyrrhizae/liquorice and ephedrine in Ephedra sinica. The proposed system set-up for this current work was simpler as no heating and back pressure regul...

A 6-week growth trial was conducted to compare the effects of different feeding strategies of dietary immunostimulants on the growth and immunity of white shrimp Litopenaeus vannamei (4.70 ± 0.20 g). Six feeding strategies were set, including feeding immunostimulants-free diet continuously (con...

By means of glycyrrhizin (GL)-affinity column chromatography, a GL-binding lipoxygenase (gbLOX) was selectively purified from the partially purified soybean LOX-1 fraction. Polypeptide analysis of the purified gbLOX by SDS-PAGE detected two distinct polypeptides (p96 and p94), which were identic...

The aim of the present work was to investigate the potential utility of chitosan nanoparticles surface modified with glycyrrhizin (CS-NPs-GL) as new hepatocyte-targeted delivery vehicles. For this purpose, chitosan nanoparticles (CS-NPs) were prepared previously by ionic gelation process and gly...

BackgroundCold ischemic injury in liver storage is an important issue pertaining to liver transplantation. Glycyrrhizin (GL), the glycoconjugated triterpene produced by the root of the licorice plant, has been used to treat chronic hepatitis; however, its function against cold ischemia injury re...

Alpha-naphthyl isothiocyanate (ANIT) is a common hepatotoxicant experimentally used to reproduce the pathologies of drug-induced liver injury in humans, but the mechanism of its toxicity remains unclear. To determine the metabolic alterations following ANIT exposure, metabolomic analyses was per...

A novel β-glucuronidase from filamentous fungus Penicillium purpurogenum Li-3 was purified to electrophoretic homogeneity by ultrafiltration, ammonium sulfate precipitation, DEAE-cellulose ion exchange chromatography, and Sephadex G-100 gel filtration with an 80.7-fold increase in specific acti...

Root extract of liquorice is traditionally used to treat several diseases. Liquorice-derived constituents present several biological actions. In particular, glycyrrhizin and its aglycone, glycyrrhetinic acid, exhibit well-known cardiovascular properties. The aim of this research was to explore t...

Thrombin activates immunocompetent microglia and increases release of inflammatory cytokines under intracerebral hemorrhage (ICH) insults. Also, thrombin injection into the striatum evokes acute necrosis and delayed apoptosis of neurons. A nucleoprotein high-mobility group box 1 (HMGB1) that is ...

Gasdermin D (GSDMD), a genetic substrate for inflammatory caspases, plays a central role in pyroptosis of macrophages and release of interleukin‑1β (IL-1β), but was mainly referred to microbial infection. High mobility group box-1 (HMGB1), served as an alarm molecule during various pathologica...

Phosphatidylinositol 3-kinase (PI3K) signaling pathway has diverse functions, including the regulation of cellular survival, proliferation, cell cycle, migration, angiogenesis and apoptosis. Among class I PI3Ks (PI3Kα, β, γ, δ), the PIK3CA gene encoding PI3K p110α is frequently mutated and ...
