Rationale Mummification is one of the defining customs of ancient Egypt. The nuances of the embalming procedure and the composition of the embalming mixtures have attracted the attention of scientists and laypeople for a long time. Modern analytical tools make mummy studies more efficient. Methods Comprehensive two-dimensional gas chromatography-high resolution mass spectrometry (GCxGC/HRMS) with complementary ionization methods (electron ionization, positive chemical ionization, and electron capture negative ionization [ECNI]) with a Pegasus GC-HRT+4D instrument was used to identify embalming components in the mummy from the Pushkin Museum of Fine Arts acquired in 1913 in London at the de Rustafjaell sale. The mummy dates back to the late Predynastic period (direct accelerator mass spectrometry-dating 3356-3098 bc), being one of the oldest in the world. Results The results showed the complexity of the embalming mixtures that were already in use 5000 years ago. Several hundred organic compounds were identified in the mummy samples. Various types of hydrocarbons (triterpanes, steranes, isoprenoid, and polycyclic aromatic hydrocarbons) prove the presence of petroleum products. Iodinated compounds detected using ECNI define oils of marine origin, whereas esters of palmitic acid indicate the use of beeswax. The nature of the discovered components of conifer tar proves that the preliminary processing of conifer resins involved heating. GCxGC/HRMS also allowed a number of modern contaminants (phthalates, organophosphates, and even DDT) to be identified. Conclusions Application of a powerful GCxGC/HRMS technique with complementary ionization methods allowed significant widening of the range of organic compounds used for mummification that could be identified. The complexity of the embalming mixtures supports the hypothesis of the high social status of the child made on the basis of the preliminary study of the mummy.

Chloroform, a regulated disinfection by-product in water, is often generated during chlorination disinfection treatment. However, the formation of chloroform is heavily dependent on the molecular structures of precursors. Moreover, compounds containing ketone moiety are ubiquitous in water environments. However, it is unclear if they can generate chloroform during chlorination. In this study, 14 benzophenones (BPs), efficient and widely used UV filters, with different substituents were selected to explore chloroform formation during chlorination. All 14 BPs generated chloroform, with yields dependent on their molecular structures and operational conditions. Compounds 2,2′,4,4′-tetrahydroxy-BP and benzophenone produced the highest and lowest chloroform of 0.313 and 0.013 g/g, respectively, corresponding to the fastest and slowest formation rate constants of 1.41 x 10(-1) and 2.71 x 10(-2) min(-1). Alkaline conditions and high chlorine dosages were favorable to chloroform formation. Three reactions played key roles in chloroform formation from BPs: (1) chlorine initiated Baeyer Villiger oxidation converted ketone moieties of BP molecules into esters; (2) the esters further underwent hydrolysis and formed phenolic and benzoic products; and (3) benzoic acids underwent decarboxylation and hydrolysis to form phenolic products. Subsequently, these phenolic products could further generate chloroform in the chlorination system. More importantly, BPs could generate chloroform in the ambient water matrices during practical chlorination treatment. This work emphasized the critical role of Baeyer-Villiger oxidation for chloroform formation, implying that pollutants containing aromatic ketone moieties generate chloroform during chlorination disinfection, and their potential risk should therefore be reviewed.

In the presence of K2S2O8 and HOAc, 3-(2-azidoaryl) substituted propargyl alcohols can go through chemoselective oxidative radical cyclizations to give a pool of anthranils based on Meyer-Schuster rearrangement. It’s proposed that the cyclizations were triggered exclusively by the direct attack of oxygen radicals on the azides. The weak N-O bonds in anthranils could be easily cleaved in the presence of transition metal catalysts and went through aminations with 2-oxo-2-phenylacetic acid and iodobenzene.

This study’s aim was to determine the pesticide residues in 10 different vegetable commodities from the Asir region, Saudi Arabia. We evaluated 211 vegetable samples, collected from supermarkets between March 2018 and September 2018, for a total of 80 different pesticides using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) after extraction with a multi-residue method (the QuEChERS method). The results were assessed according to the maximum residue limit (MRL) provided by European regulations for each pesticide in each commodity. All lettuce, cauliflower, and carrot samples were found to be free from pesticide residues. A total of 145 samples (68.7%) contained detectable pesticide residues at or lower than MRLs, and 44 samples (20.9%) contained detectable pesticide residues above MRLs. MRL values were exceeded most often in chili pepper (14 samples) and cucumber (10 samples). Methomyl, imidacloprid, metalaxyl, and cyproconazole were the most frequently detected pesticides. Based on the results of this study, we recommend that a government-supported program for the monitoring of pesticide residues in vegetables be established to promote consumers’ health and achieve sustainable farming systems.

2, 3-Dihydroquinazolinones are of popular compounds with the diversification of biological and pharmacological activities. Among many discovered methods, there are efficient and convenient methods used for the synthesis of 2, 3-dihydroquinazoline-4 (1H)-one and some new bis 2, 3-dihydroquinazoline-4 (1H)-one derivatives which are reported in this study. The mentioned methods include the two-component condensation of one molecule of anthranilamide and one molecule of pyrazole carbaldehyde using montmorillonite-K 10 as a catalyst for the preparation of 2, 3 dihydroquinazoline-4 (1H)-ones. Also, one-pot pseudo-five-component reaction (5MCRs) of two molecules of isatoic anhydride, two molecules of pyrazole carbaldehydes and one molecule of ethan-1, 2-diamine in the presence of the r catalyst (montmorillonite-K10) for the synthesis of bis 2, 3-dihydroquinazoline-4 (1H)-ones. Despite the short times of reactions, high yields of products were obtained, which were validated using FT-IR, (HNMR)-H-1, (CNMR)-C-13, and elemental analysis. Moreover, the compounds were screened for their antimicrobial activities against two-gram-positive bacterial strains: Staphylococcus aureus and Micrococcus Luteus; and against two-gram-negative bacterial strains, as well: Escherichia coli and Pseudomonas aeruginosa, which all were utilized for antibacterial investigations. The results showed moderate or significant antibacterial activities.

A three-step synthesis of 3 ‘,5 ‘-dichloro-1H-spiro(quinazo-line-2,4 ‘-[1,2,6]thiadiazin)-4(3H)-ones starting from 3,4,4,5-tetra-chloro-4H-1,2,6-thiadiazine is presented. The latter reacts with 2-aminobenzonitriles to give 2-[(3,5-dichloro-4H-1,2,6-thiadiazin-4-ylid-ene)amino]benzonitriles, which affords, after hydration, the respective benzamides. Upon heating at reflux in EtOH or HFIP, the benzamides intramolecularly cyclize onto the thiadiazine C4 position to give 3 ‘,5 ‘-dichloro-1H-spiro(quinazoline-2,4 ‘-[1,2,6]thiadiazin)-4(3H)-ones. Single crystal X-ray crystallography supports the structure of two analogues. The chloride displacement of these new spiroquinazolinones was demonstrated by Stille coupling, and by reaction with methoxide to afford both the mono and bis-methoxy derivatives.

Quality Control of Benzophenone. I found the field of Marine & Freshwater Biology; Toxicology very interesting. Saw the article Potentiation of lethal and sub-lethal effects of benzophenone and oxybenzone by UV light in zebrafish embryos published in 2021.0, Reprint Addresses Goss, G (corresponding author), Univ Alberta, Dept Biol Sci, 11455 Saskatchewan Dr, Edmonton, AB T6G 2E9, Canada.; Goss, G (corresponding author), Natl Inst Nanotechnol, 11421 Saskatchewan Dr, Edmonton, AB T6G 2M9, Canada.; Goss, G (corresponding author), Univ Alberta, Off Environm Nanosafety, Edmonton, AB, Canada..

Benzophenones are widely used as organic UV filters in many personal care products, especially sunscreen, to protect humans from UV radiation. The increasing use of benzophenone class UV filters has raised concerns about the potential effects on the aquatic environment. These organic UV filters are designed to absorb UV light. However, to date, studies have not considered the potential of UV light to potentiate the toxicity of benzophenones in aquatic organisms. In this study using zebrafish embryos, we assessed the median lethal concentration (LC50) and sub-lethal effects of benzophenone and oxybenzone either under natural levels of UV light or under laboratory light conditions. The LC50 value in zebrafish embryos under both light conditions of oxybenzone was lower when compared to benzophenone. Interestingly, UV light significantly decreased the LC50 values (increased toxicity) of both benzophenone and oxybenzone. The presence of UV light induced a significant increase in hydroxyl radical formation and this was reflected in both increased SOD activity and lipid peroxidation in oxybenzone treated groups. Exposure to either benzophenone or oxybenzone also delayed hatching between 60 and 96 hpf when comparing to the control group while UV exposure further delayed hatching only in oxybenzone-exposed embryos. The results demonstrate the importance of involving UV light in toxicity testing for UV filters and provide much-need information on the UV-induced toxicity of benzophenone and oxybenzone under ecologically realistic conditions.
