Blueberry, raspberry, and strawberry extracts reduce the formation of carcinogenic heterocyclic amines in fried camel, beef and chicken meats

Heterocyclic amines (HCAs) are toxic products from the Maillard reaction that form from the reaction of sugars, amino acids and creatine/creatinine when cooking protein rich food. In this work, commonly consumed meats in Saudi Arabia (camel, beef and chicken) were fried under conditions resembling home cooking. The effect of marinades made of blueberry, raspberry and strawberry were tested separately on meat at different marinating times (1, 6, 12, 24h, at 4 degrees C) before frying. The marinades caused an overall reduction of HCAs. The decrease was more noticeable with long marination time >= 6h. The reduction of individual HCAs, after 24h marinades, was 91-100% for pyridines; 40-67% for beta-carbolines; and 100% for quinoxalines, quinolines, alpha-carbolines and gamma-carbolines, although the latter three were seldomly detected in this study. An increase, up to 2 times, on the formation of the studied quinoxalines was observed in every meat and marination for no more than 1h. Therefore, longer marinating times with berry extracts, from 6h, are recommended over those below (1h).

Synthesis of nanorod MOF catalyst containing Cu2+ and its selective oxidation of styrene

Different from the traditional aldimine condensation reaction, N-containing ligand: pyridine-2-formaldehyde was selected as the source of aldehyde group, and NH2-MIL-53(Al) containing a large number of amino functional groups was took as the carrier, transition metal Cu2+ coordinated with N-containing ligand to prepare a new and more stable MOFs catalyst named Cu@Al-MIL-53-P21. The catalyst exhibited a cross-linked nanorod morphology. The effect of the morphology on the catalytic oxidation activity of styrene was studied, the results showed that the catalyst could not only promote the production of benzaldehyde, but also inhibit the production of benzoic acid and phenylacetaldehyde. In addition, the optimal reaction conditions and the reaction mechanism were also discussed in this paper.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 91-02-1, in my other articles.

New Approach to the Synthesis of 2-Sulfonylaminosubstituted Imidazo[1,2-a]pyridines via the Cascade Reaction of N-(1-aryl-2,2,2-trichloroethyl) sulfonamides with 2-Aminopyridines

2-Aminopyridines react with N-(1-aryl-2,2,2-trichloroethyl)arenesulfonamides in the presence of K2CO3 and DABCO to afford previously unknown 2-sulfonylaminosubstituted imidazo[1,2-a]pyridines.

Broadband rotational spectroscopy of trans 3-pentenenitrile and 4-pentenenitrile

Titan, a moon of Saturn, has a nitrogen- and methane-rich atmosphere that is similar to prebiotic earth, and is replete with organic nitriles. Pentenenitriles have not yet been detected in Titan’s atmosphere or in molecular clouds, but are potential precursors to hetero-aromatic compounds such as pyridine. We performed broadband microwave studies in the 8-18 GHz range on the trans isomer of 3-pentenenitrile (3-PN) and 4-pentenenitrile (4-PN) under jet-cooled conditions. Strong-field coherence breaking (SFCB) was used to selectively modulate the intensities of microwave transitions in a conformer-specific manner for 3-PN, aiding analysis. Two conformers of 3-PN and five conformers of 4-PN were identified and the rotational transitions were assigned. Evidence for methyl internal rotation splitting was observed for both the conformers of 3-PN, and the barrier heights of both conformers was determined experimentally. Comparison is made of the conformational preferences, stability and isomerization barriers through the acquired rotational spectra and potential energy surface (PES) calculations of the structural isomers 3-PN and 4-PN.

Structure-Activity Relationship Studies of Pyridine-Based Ligands and Identification of a Fluorinated Derivative for Positron Emission Tomography Imaging of Cannabinoid Type 2 Receptors

The cannabinoid type 2 (CB2) receptor has emerged as a valuable target for therapy and imaging of immune mediated pathologies. With the aim to find a suitable radiofluorinated analogue of the previously reported CB2 positron emission tomography (PET) radioligand [C-11]RSR-056, 38 fluorinated derivatives were synthesized and tested by in vitro binding assays. With a K-i (hCB2) of 6 nM and a selectivity factor of nearly 700 over cannabinoid type 1 receptors, target compound 3 exhibited optimal in vitro properties and was selected for evaluation as a PET radioligand. [F-18]3 was obtained in an average radiochemical yield of 11 +/- 4% and molar activities between 33 and 114 GBq/mu mol. Specific binding of [F-18]3 to CB2 was demonstrated by in vitro autoradiography and in vivo PET experiments using the CB2 ligand GW-405 833. Metabolite analysis revealed only intact [F-18]3 in the rat brain. [18F]3 detected CB2 upregulation in human amyotrophic lateral sclerosis spinal cord tissue and may thus become a candidate for diagnostic use in humans.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 1202-34-2. SDS of cas: 1202-34-2.

Hydrogen-free hydrogenation of furfural to furfuryl alcohol and 2-methyl-furan over Ni and Co-promoted Cu/gamma-Al2O3 catalysts

Catalytic transformation of furfural to furfuryl alcohol and 2-methylfuran without H-2 supply toward transfer hydrogenation process using 2-propanol as a H-2 source was systematically investigated over the bimetallic NiCuAl and CoCuAl catalysts in comparison with the monometallic CuAl, NiAl, and CoAl catalysts. The XRD analysis confirmed the generation of Ni-Cu and Co-Cu alloys after the reduction in presence of H-2. The interaction between Cu and Ni or Co resulted in a simplicity of the reduction behavior of Ni and Co species observed in H-2-TPR experiments. It was evident from pyridine adsorption FTIR analysis that the formation of bimetallic NiCu and Co-Cu alloys apparently improved the stronger Lewis acidic sites. The influences of reaction temperature and time were examined and optimized to maximize the yields of furfuryl alcohol and 2-methylfuran. The highest two major products yield and selectivity with lower by-products were obtained over the NiCuAl and CoCuAl catalysts compared with the CuAl and NiAl catalysts. The superior performance of the bimetallic catalysts was attributed to the stronger Lewis acidic centre on the catalyst surface. The CoCuAl catalyst was found to have lower catalyst deactivation and carbon deposition among the CuAl and NiCuAl catalysts under H-2-free atmosphere.

Unprecedented Formation of 2-Chloro-5-(2-chlorobenzyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine 5-oxide via Oxidation-Chlorination Reaction Using Oxone: A Combination of Synthesis and 1D-2DNMR Studies

Ticlopidine hydrochloride (1 center dot HCl, Ticlid (TM)) is a prodrug that, through bioactivation by cytochrome P450 (CYP), interacts with the P2Y(12) receptor ADP inhibiting platelet aggregation. This prodrug mediated by a multistep biochemical process led to the formation of active metabolic intermediates. In this work, an eco-friendly and efficient protocol for the formation of 2-chloroticlopidine (2) using 1 center dot HCl and oxone in aqueous methanol media via an unprecedented formation of reactive thienopyridine intermediate 2-chloro-5-(2-chlorobenzyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine 5-oxide (4) was developed. The key to success of 4 is the oxidation of tertiary amines to N-oxides, followed by mono-chlorination at the 2-position of the thiophene ring by oxidation of the chloride counterion of this prodrug. In addition, we use the 1D and 2DNMR techniques as a tool to monitor reaction progress, and for assigning the signals of all compounds involved, especially for the novel thienopyridine 4.
