Younis, Osama published the artcileSolid-State Luminescent Materials Containing Both Indole and Pyrimidine Moieties: Design, Synthesis, and Density Functional Theory Calculations, Recommanded Product: 2-Chloroacetamide, the publication is ACS Omega (2022), 7(17), 15016-15026, database is CAplus and MEDLINE.

Heterocyclic compounds with effective solid-state luminescence offer a wide range of uses. It has been observed that combining pyrimidine and indole moieties in a single mol. can enhance material behavior dramatically. Here, different heterocyclic compounds with indole and pyrimidine moieties have been synthesized effectively, and their structures have been validated using NMR, IR, and mass spectroscopy. The photoluminescence behavior of two substances was investigated in powder form and solutions of varying concentrations After aggregation, one mol. displayed a red shifted luminescence spectrum, whereas another homolog showed a blueshift. Thus, d. functional theory calculations were carried out to establish that introducing a terminal group allows modifying of the luminescence behavior by altering the mol. packing. Because of the non-planarity, intermol. interactions, and tiny intermol. distances within the dimers, the materials demonstrated a good emission quantum yield (Φ_em) in the solid state (ex. 25.6%). At high temperatures, the compounds also demonstrated a stable emission characteristic.

Penalver, Lilian published the artcileA ligand selection strategy identifies chemical probes targeting the proteases of SARS-CoV-2, Application of 2-Chloroacetamide, the publication is Angewandte Chemie, International Edition (2021), 60(12), 6799-6806, database is CAplus and MEDLINE.

Activity-based probes are valuable tools for chem. biol. However, finding probes that specifically target the active site of an enzyme remains a challenging task. Herein, we present a ligand selection strategy that allows to rapidly tailor electrophilic probes to a target of choice and showcase its application for the two cysteine proteases of SARS-CoV-2 as proof of concept. The resulting probes were specific for the active site labeling of 3CL^pro and PL^pro with sufficient selectivity in a live cell model as well as in the background of a native human proteome. Exploiting the probes as tools for competitive profiling of a natural product library identified salvianolic acid derivatives as promising 3CL^pro inhibitors. We anticipate that our ligand selection strategy will be useful to rapidly develop customized probes and discover inhibitors for a wide range of target proteins also beyond corona virus proteases.

Forkel, Susann published the artcileThe benefit of late readings in patch testing depends both on allergen and patient characteristics, HPLC of Formula: 79-07-2, the publication is Allergy (Oxford, United Kingdom) (2022), 77(5), 1477-1485, database is CAplus and MEDLINE.

Patch test (PT) readings are recommended after 48 h and 72 h (D3). An addnl. day 7 (D7) reading has been suggested by some, although data on efficient patient selection are scarce. We investigated pos. D7 reactions regarding (i) allergens in the baseline series and addnl. PT series of the German Contact Dermatitis Research Group (DKG) and (ii) characteristics of the patients tested. Retrospective, multicentre anal. of 190 allergens derived from 17 DKG test series in 4687 patients with an addnl. D7 reading. Patients were patch tested with the baseline series and addnl. series, if required. Occurrence of novel D7 reactions as well as increasing skin reactions from D3 to D7 was analyzed sep. Depending on the allergen tested, waiving D7 readings would have missed 4.4-26.8% of pos. PT results. Patch test series with the highest number of novel D7 reactions were baseline series, metal series, and leather/shoe series. New pos. reactions on D7 were associated with age over 50 years and with a neg. irritant control containing sodium lauryl sulfate. Of note, application of the PT allergens for 48 h instead of 24 h was pos. associated with late PT reactions. Within the most frequently tested allergens, without late readings, on average 11.7% of sensitizations would have been missed. Novel late reacting allergens were identified. This study comprehensively dissects patient-, allergen- and test-dependent parameters in support for D7 readings. We propose to always consider late readings individually based on effort-benefit considerations.

Brodeur, Julie C. published the artcileThe problem with implementing fish farms in agricultural regions: A trial in a Pampean pond highlights potential risks to both human and fish health, Synthetic Route of 79-07-2, the publication is Chemosphere (2021), 128408, database is CAplus and MEDLINE.

The safety of creating fish farms in agricultural settings was evaluated by growing Piaractus mesopotamicus in a pond, while crops where cultivated in a nearby field under a pesticide application regime typical of the Pampa region. Atrazine, glyphosate, and its metabolite aminomethylphosphonic acid (AMPA) were detected in the water of the pond at concentrations ranging 92-118μg/L for atrazine, 12-221μg/L for glyphosate, and 21-117μg/L for AMPA. Atrazine and malathion were detected in fish muscles at concentrations ranging 70-105μg/kg for atrazine and 8.6-23.7μg/kg for malathion. Compared to fish raised in a pisciculture, fish from the agricultural pond presented reduced values of pack cell volume, Hb, mean corpuscular Hb and mean corpuscular Hb concentration, together with significantly greater cholinesterase activity in both plasma and liver and reduced glutathione-S-transferase activity in the liver. A comet assay also demonstrated that P. mesopotamicus from the agricultural pond presented a significantly greater level of DNA damage in both erythrocytes and gill cells. Overall, the present study demonstrates that pisciculture ponds established in an agricultural setting may receive pesticides applied to nearby cultures and that these pesticides may be taken up by the fish and affect their physiol. and health. The accumulation of pesticide residues in fish flesh may also present a risk to human consumers and should be closely controlled.

Drug discovery is an expensive and time-consuming process. To make this process more efficient quantum chem. methods can be employed. The electrophilicity index is one property that can be calculated by quantum chem. methods, and if calculated correctly gives insight into the reactivity of covalent inhibitors. Herein we present the usage of the electrophilicity index on three common warheads, i.e., acrylamides, 2-chloroacetamides, and propargylamides. We thoroughly examine the properties of the electrophilicity index, show which pitfalls should be avoided, and what the requirements to successfully apply the electrophilicity index are.

A new optimal synthetic scheme for new antibacterial compounds I (R = H, Me) combining tris-(1-alkyindol-3-yl)methylium and 3-(indol-1-yl)maleimide in their structures was developed. The proposed method provided a significant increase in the product yield, reduced the labor intensiveness and number of steps, and used readily accessible starting reagents. A good yield was achieved for 3-(formylindol-1-yl)-4-chloromaleimide, a universal precursor enabling two-step syntheses of target tri(indolyl)methanes II (R¹ = H, NH₂, NMe₂) and production of an extensive library of analogous potentially active compounds from other 1-alkylindoles and various amines and thiols.

The alkylation of 5-(5-bromofuran-2-yl)-4-methyl-1,2,4-triazole-3-thiol with bromoalkanes was carried out. Synthesis was accomplished by addition of equivalent amounts of bromoalkanes (bromomethane, bromoethane, bromobutane-bromodecane) to 5-(5-bromofuran-2-yl)-4-methyl-1,2,4-triazole-3-thiol in a methanol medium in the presence of an equivalent amount of sodium hydroxide. Compounds were obtained with a high yield. The next step was to investigate the reaction of 5-(5-bromofuran-2-yl)-4-methyl-1,2,4-triazole-3-thiol with some other halogen-containing compounds, the mechanism of the reaction of which also relates to nucleophilic substitution. As halogen-containing compounds, we used bromoacetone, bromoacetophenone, chloroacetic acid and chloroacetamide. Under these conditions, a series of new compounds were synthesized. Structure of compounds was confirmed by ¹H NMR spectroscopy and elemental anal. The antibacterial activity of the synthesized compounds towards cryogenic strains of Enterobacteriaceae, Pseudomonadaceae, Staphylococcaceae, Bacillaceae, Listeriaceae, Corynebacteriaceae and Saccharomycetaceae families in vitro was also investigated. According to the data obtained, one can conclude that the investigated compounds can compete with kanamycin, a natural broad-spectrum antibiotic from the second generation of aminoglycosides, whose range of action includes gram-pos. and gram-neg. microorganisms. The compounds involved may be recommended for further investigation of their action against multi-resistant strains of microorganisms.
