The supermolecule approach has been used to model molecules embedded in a solid argon matrix. The interaction between the guest and the host atoms in the first solvation shell (FSS) are evaluated using density functional calculations while that beyond the FSS is incorporated using ONIOM calculat...

3H-1,2-Benzoxathiole 2,2-dioxides (benzosultones) undergo thermal extrusion of sulfur dioxide to form ortho-quinone methides that enter Diels–Alder reaction with maleimides to form chroman 2,3-dicarboxylic acid derivatives.

Gramine, a natural indole alkaloid found in Hordeum vulgare has been possesses anti-mutagenic properties. The aim of the present study was to evaluate the effect of gramine on inflammation and proliferation in 7,12-dimethylbenz[a]anthracene(DMBA)-induced hamster buccal pouch (HBP) carcinogenesis...

Basing on the previous syntheses of ester compounds containing gramine functional groups, the researchers synthesized two novel acylamino compounds containing gramine groups and the structures of target compound were established using 1HNMR, 13CNMR, IR spectra, and elemental analysis. The antiba...

In this work, a series of hydrophobic ionic liquids (ILs) with ClO4−, BF4−, PF6−, CF3SO3− and bis(trifluoromethanesulphonyl)imide (NTf2−) as anions were synthesized. Their extraction ability for the two alkaloids, quinine and gramine was studied. The experimental results suggested that the extra...

BackgroundTransforming growth factor-β (TGF-β) and its receptors are considered as a novel target in cancer chemotherapy. Gramine, an indole alkaloid, possesses various pharmacological properties including antiproliferative and anticancer. However, the anti-angiogenic property remains unexplored.

The aim of this study was to develop an efficient sorbent for separation of N,N-dimethyl-3-aminomethylindole (gramine) from bovine serum albumin. An imprinting technology was involved in the synthesis of polymers from nine different functional monomers in the presence of ethylene glycol dimethac...

Bile acids (lithocholic: LCA, deoxycholic: DCA and cholic: CA) and their formyl- and acetyl-derivatives can be used as starting material in chemical synthesis of compounds with different biological activity strongly depended on their chemical structures. Our previous studies showed that biologic...

The feasibility of using supercritical CO2 assisted by ultrasound (SC-CO2-HPU) in continuous mode (3.06 min residence time) for the non-thermal pasteurization of orange juice was evaluated. The proposed technology was effective for microbial inactivation; complete inactivation was obtained for E...

Secondary food allergies due to cross-reactivity between inhalant and food allergens are a significant and increasing global health issue. Cross-reactive food allergies predominantly involve plant-derived foods resulting from a prior sensitization to cross-reactive components present in pollen (...

Green synthesis of nanoparticles via plant extract is a novel method to spread over in the field of nanoscience and nanotechnology. Nanoparticles prepared by biological route are an eco-friendly as well as yields good results than the conventional methods. In this present work we have synthesize...

In this study, the copper nanoparticles (Cu NPs) reactivity for degradation of the reactive dye black 5 (RP5), picric acid (PA) and 2,4-D herbicide was evaluated. The RP5 degradation occurred by oxidative via, through hydroxyl radicals generated in situ, with active participation of Cu(I) and H2...

This work devoted to the investigation of adsorption of reactive orange 12 (RO-12) by gold nanoparticles loaded with activated carbon (Au-NP-AC), which in high efficiency by routine manner was synthesized in our laboratory. Generally, in batch adsorption procedure, the effect of variables, inclu...

The impact of fresh squeezed orange juice (fresh OJ) and processed orange juice (processed OJ) on blood glucose and insulin was investigated. Prospective food intake and the short-term antioxidant effect were measured. Adult men and women (n = 36), lean and obese, were challenged on three differ...

A pyrex glass semi-batch reactor was used for the pyrolysis of orange bagasse screened at 425 μm. The effect of temperature (350–600 °C), heating rate (25–100 °C min−1) and N2 gas flow rate (0.1–0.5 L min−1) on the product yield was observed. The highest pyrolysis oil yield of 35.53 wt. % ...

The solubility as well as its behaviors of a new reactive disperse orange SCF-AOL2 dye in supercritical carbon dioxide fluid, which is a potentially useful special dye for the coloration of natural fibers, was experimentally determined and investigated successfully by employing an improved batch...

Inspired by the hydrophilic, biocompatible, adsorbent properties of chitosan. A simple, adaptable, green synthesis method was developed to prepare a thin film composite membranes using chitosan as a pore decorating material for the removal of anionic dye-Reactive orange 16 (RO-16). The hydrophil...

Orange peel powder was chemically modified to enhance quaternary amine type content on the surface of adsorbent which was named as quaternary amine modified orange peel powder (QAMOPP). The effecting parameters on adsorption of Reactive Red (RR) 120 such as pH (2.0–9.0), contact time (0–300 mi...

Enantiomerically pure (S)-3-amino-3-(o-tolyl)propanoic acid [(S)-6], identified as the preferred enantiomeric form for the construction of novel β-amino acid derivatives as inhibitors of Cathepsin, was prepared through both indirect and direct enzymatic strategies. Resolution of hydroxymethylat...

In this study, we examined the antihyperglycemic and antidiabetic effects of a novel synthesized molecule, the Ethyl (S)-2-(1-cyclohexylsulfamide carbamoyloxy) propanoate (ESP1b), in streptozotocin (STZ)-induced diabetic Wistar rats. Experimental diabetes mellitus was produced by a single intrap...
