Resumen

The studies carried out made it possible to establish that during the industrial preparation of second lunch dishes with a garnish, heterocyclic aromatic amines are formed in the meat components. Heterocyclic aromatic amines were found in all samples tested. However, the lack of information on the preparation technology of the selected samples does not allow a full analysis of the results obtained. The largest amount of heterocyclic aromatic amines was formed in samples with chicken meat, which was prepared at the highest temperatures relative to other samples. The presence of heterocyclic aromatic amines in all studied samples indicates the potential harm of consumption of such products for human health

Resumen

In the selective N-arylation of amines or azoles with aryl halides, methyl-α-d-glucopyranoside (MG) was found to function as a green ligand of copper powder. In addition, nitrogen heterocyclic amine compounds can also undergo the N-arylation coupling with heterocyclic aryl chlorides. This process allows access to a variety of aromatic amines and aryl azoles under mild reaction conditions, has good tolerance, and proceeds in moderate to high yield.

Resumen

Efficient and versatile catalytic systems were developed for the N-methylation of both aliphatic and aromatic primary amines using methanol as the methylating agent. Iridium complexes bearing an N-heterocyclic carbene (NHC) ligand exhibited high catalytic performance for this type of transformation. For aliphatic amines, selective N,N-dimethylation was achieved at low temperatures (50–90 °C). For aromatic amines, selective N-monomethylation and selective N,N-dimethylation were accomplished by simply changing the reaction conditions (presence or absence of a base with an appropriate catalyst). These findings can be used to develop methods for synthesizing useful amine compounds having N-methyl or N,N-dimethyl moieties.

Resumen

Biogenic Amines (BA) are low molecular weight organic bases that have biological activity, they can be formed and degraded as a result of normal metabolic activity in animals, plants and microorganisms, and are usually produced by the decarboxylation of amino acids. The most common biogenic amines which can be found in foods are aliphatic (putrescine, cadaverine, spermine, spermidine), aromatic (tyramine, phenylethyl amine) or heterocyclic (histamine, tryptamine) structures.

Resumen

The aim of the present study was to evaluate the effects of grilling temperatures on the formation of heterocyclic aromatic amines (HAAs) in steaks from the pork loin (longissimus lumborum muscle). Grilling was carried out on a double hot plate grill set to the usual grilling temperatures of 120 °C to 280 °C and stopped when the internal temperature of 72 °C was reached. Among individual HAAs, the most abundant was 2-amino-1-methyl-6-phenylimidazo(4,5-b)pyridine (PhIP), as a maximum of 28.62 ng g<sup>–1</sup> pork steak. in general, the total HAA levels increased with increasing grilling temperature. Higher HAA levels were observed at 260 °C compared to 240 °C, at 13.97 ng g<sup>–1</sup>, as a 68.7% increase. The highest total HAA levels were found at 280 °C (29.64 ng g<sup>–1</sup> grilled pork steak), as a 258.0% increase compared to 240 °C. These data indicate that the formation of potentially carcinogenic HAAs during the grilling of pork steaks can be minimised by the using of lower grilling temperatures (≤ 240 °C).

Resumen

Frequent consumption of thermally processed meat was classified by the International Agency for Research on Cancer to directly carcinogenic agents for humans. During the heat treatment of high protein food, mutagenic and carcinogenic, as well as neurotoxic heterocyclic aromatic amines are formed. Epidemiological studies confirm that exposure to some of these compounds may increase the risk of cancer in humans, especially the colon cancer. Most heterocyclic amines contain fried and grilled meat products, and the lowest content of these compounds can be found in boiled and slightly baked dishes. The use of spices and vegetable additives with antioxidant properties allows to obtain dishes with reduced content of these xenobiotics. An effective way to reduce human exposure to cancerogenic amines may be simultaneous consumption, together with meat dishes, products containing fiber which can adsorb molecules of heterocyclic amines in the gastrointestinal tract, as well as enrichment of the diet in the crucifers plants, as isothiocyanates released from them can inhibit the metabolic activation processes of heterocyclic amines. Raising the public awareness of the formation of mutagenic and carcinogenic compounds, including heterocyclic aromatic amines, during the intensive heat treatment of high protein food, as well as the dissemination of knowledge on the conditions regarding the preparation of dishes with reduced content of such compounds could become one of the components of cancer prevention programs in Poland.

Resumen

Quenching of the room-temperature solid-matrix phosphorescence (SMP), near-infrared spectrometry, differential scanning calorimetry, and a polarity probe were used to study interactions of heterocyclic aromatic amines in glucose glasses prepared using crystalline glucose and a glucose melt. A near-infrared spectrometry method was developed to determine the wt % moisture in the glucose glasses. The wt % moisture of the glucose glasses was then related to phosphorescence intensities and lifetime ratios of the heterocyclic aromatic amines. A modified form of the Stern–Volmer equation was used to describe the changes in phosphorescence intensity and lifetime ratios. In other experiments, the glass transition temperatures of the glucose glasses were determined using differential scanning calorimetry. The glass transition temperatures were then correlated to the SMP of the heterocyclic aromatic amines in the glucose glasses. Lastly, the micro-environmental polarities of the glucose glasses were studied using a polarity probe. From these results a model was developed that described the effects of several parameters on the glucose glass matrices. For example, water was able to diffuse through channels in the glucose glasses and cause dynamic quenching of the phosphorescence. Also, the hydrogen bonding network in the glucose glasses was disrupted by water. This resulted in matrix quenching of the phosphorescence signals.

Resumen

Aim and Objective: The late transition metal complexes with five-membered heterocyclic mono-imine ligands have attracted much attention because of their potential application in olefin polymerization catalysis. In order to increase the coordination ability of heteroatom N and S to center metals, CH3 group was introduced into the side arm of pyrrole imine and thiophene imine respectively, to get two series of novel five-membered heterocyclic imine compounds, mono(imino)pyrroles and mono(imino)thiophenes Materials and Methods: Two series of novel five-membered heterocyclic compounds with the mono-imine group were synthesized from the p-toluene sulfonic acid catalyzed Schiff base condensation of aromatic amines and 2-acetylpyrrole/ 2-acetylthiophene respectively, using CH3 group to substitute the common H atom on the side arm of pyrrole imine/ thiophene imine. Results: All the heterocyclic mono-imine compounds were characterized adequately by means of 1H NMR, 13C NMR, FT-IR, elementary analysis, as well as X-ray crystallographic diffraction. The reactivity differences between two precursor 2-acetylpyrrole and 2-acetylthiophene with aromatic amines were compared and discussed in detail. Conclusion: Compared to traditional heating methods, the solvent-free microwave irradiation seemed more efficient to prepare these series of five-membered heterocyclic mono-imine compounds, which resulted in a higher yield and cleaner product.

Resumen

This article reports on the reaction of 2-hetaryl-2-(furanyl-2-ylidene)acetonitriles with aromatic amines as N-nucleophiles. 2-Hetaryl-2-(furanyl-2-ylidene)acetonitriles represent versatile building blocks in syntheses of ω-(N-aryl)alkyl substituted heterocycles due to the presence of 1,3-bielectrophilic acrylonitrile fragment functionalized with unsaturated heterocyclic ring and nucleophilic azaheterocyclic moiety. The carbonyl group masked within the N-arylpyrrolidinylidene fragment which undergoes a ring opening through the reaction with nucleophiles. So, a method for the synthesis of 2-hetaryl-6-hydroxy-3-(arylamino)hex-2-enenitriles and 2-hetaryl-2-(N-arylpyrrolidin-2-ylidene)acetonitriles has been developed by us. The proposed scheme is based on the available reagents using. As a result of Michael addition, the aromatic amines to 2-hetaryl-2-(furanyl-2-ylidene)acetonitriles followed by ring transformations has formed two types of products, depending on the reaction conditions. The reaction of substituted furanylylideneacetonitriles with aromatic amines proceeds in good to high yields affording the corresponding 3-(arylamino)hex-2-enenitriles and 2-(N-arylpyrrolidin-2-ylidene)acetonitriles derivatives. The stereochemistry of the ring-opening reaction follows the rules of a classical SN2 mechanism. The resulting linear products can be cyclized to 2-hetaryl-2-(furanyl-2-ylidene)acetonitriles in high yields by treatment with the catalytic amount of acid or the equimolar amount of aromatic amines. Under these conditions 2-hetaryl-6-hydroxy-3-(arylamino)hex-2-enenitriles arising from reaction gives the ring closure. Since both ring-opening and cyclisation occur with fixed stereochemistry the reaction appears a valuable modification to the preparation of acetonitriles derivatives.

Resumen

Against the background of adverse environmental conditions in Ukraine, experts in the field of medicine, food hygiene note the raising importance of various nutritional factors in increasing the risk of developing cancer. A number of compounds resulting from protein denaturation during the heat treatment of meat and fish products can pose a high risk. Such compounds include heterocyclic aromatic amines (HAA) i.e. substances that, in extremely low concentrations, can carry out mutagenic and carcinogenic effects on the human body. Aim of the Research. To analyse studies from available sources of information about the likelihood and conditions of the formation of chemicals hazardous to human health in foods of animal origin during thermal cooking. Methods and Materials. Review and analysis of scientific publications based on the results of experimental studies of European, American and Japanese scientists. Results and Discussion. Studies have established that in the process of thermal cooking of food products of animal meat, poultry, fish, HAA are formed and accumulate as a result of complex multi-stage chemical reactions with the obligatory participation of amino acids, sugars, creatine and creatinine, which is its cyclic form. The formation of mutagenic HAA is affected by a number of conditions. For example, the accumulation of heterocyclic aromatic amines in fried meat products is most affected by the temperature of the surface of the pan and the outer layer of meat, the duration of frying, the degree of meat chopping, the presence of breading, pickling, the addition of onions to the chopped meat. Conclusions. Taking into account that the diet of more than 40% of the population includes products containing HAA, the development and justification of safety criteria for meat and fish products concerning the content of heterocyclic aromatic amines as well as the development of ways to prevent their formation form an urgent problem. The following tasks must be solved as priorities: – to develop and standardize methods for the determination of HAA in various types of food products; – to conduct studies of the content of HAA in meat and fish products and in culinary products; – to study the influence of various methods of thermal cooking on the accumulation of HAA in finished products made from meat and fish; – to study the effect of the raw materials used and production technologies on the accumulation of HAA in food products; – to optimize the formulae of meat and fish products and their production technologies in order to minimize the number of HAA formed in the finished product; – to justify the acceptable levels of HAA in food products and to develop safety criteria for meat and fish products concerning the content of HAA on the basis of clinical and laboratory studies. Key Words: heterocyclic aromatic amines (HAA), meat products, fish products, thermal cooking, safety.

Resumen

We developed an environmentally friendly iridium-catalyzed direct cyclization of aromatic amines with diols that generates the corresponding N-heterocyclic compounds with water as the sole by-product. Thus, under conditions of 165 °C for 18 hours, the direct cyclization of N-methylanilines with 1,3-propanediol by using an IrCl3 catalyst with rac-BINAP as a ligand in mesitylene afforded the corresponding tetrahydroquinoline derivatives with yields ranging from 73 to 83%. Under similar reaction conditions, direct cyclization of anilines with 1,3-propanediol produced the corresponding tetrahydrobenzoquinolizine derivatives with yields ranging from 26 to 76%.
