In vivo animal bioassays are increasingly being supplemented with in vitro assays to serve as the new standard for chemical toxicity tests. Despite this shift, investigators face challenges related to increased reliance on in vitro data. The aim of this study was to deploy a streamlined method to assess the ability of in vitro data to predict similar results as in vivo data by correlating chemical toxicity rankings obtained using Benchmark Doses and Benchmark Dose Lower Limits (BMD(L)s) derived from in vivo and in vitro assays. In vitro and in vivo assay characteristics were assessed for their impact on the predictive ability of in vitro data. Minimum best-fit BMD(L)s were calculated for chemicals using Environmental Protection Agency’s (EPA’s) Benchmark Dose Software (BMDS). Forty-one chemicals met the inclusion criteria of this study. Relative chemical toxicity rankings were assessed through Kappa statistics, Pearson correlations, and/or Ordinary Least Squares (OLS) regressions. Results illustrated likely ability of in vitro data to predict similar results as short-term in vivo data. Further, rankings derived from in vitro cytotoxicity assays, unlike stress response assays, significantly correlated with rankings derived from short-term in vivo assays. These results support the use of in vitro data as a prioritization tool within toxicity testing.

Ball milling of calcium carbide (CaC2) enables the reaction of its ethynyl moiety with organic electrophiles. This was realized simply by co-milling CaC(2)with organic substrates in a sealed jar without the need for an additive or a catalyst. Various ketones including those bearing alpha-hydrogens were ethynylated in good yields at short reaction times. Aryl halides are also amenable substrates for this protocol as they furnish aryl ethynes through a benzyne intermediate. This method offers a practical and cheap alternative to the established procedures for introducing ethynyl functionalities.

HPLC of Formula: C14H10O. I found the field of Chemistry very interesting. Saw the article Origin and turnaround of enantioselectivity in a chiral organocatalysed Diels-Alder reaction: A mechanistic study published in 2020, Reprint Addresses Karnik, AV; Badani, PM (corresponding author), Univ Mumbai, Dept Chem, Mumbai 400098, Maharashtra, India.. The CAS is 90-44-8. Through research, I have a further understanding and discovery of Anthrone.

The present work comprises exploring the efficacies of the chiral organocatalysts employed in the classic Diels-Alder reaction between anthrone and maleimide in generating an enantioselective product. The complete mechanism of the reaction has been figured out by performing the electronic structure calculations at the density functional theory (DFT) level. Our calculations suggest that the reaction commences with the abstraction of acidic proton of anthrone instigated by organocatalysts, (S)-(-)-N-(methyl-2 ‘-pyridyl)-2-(alpha-hydroxyethyl)benzimidazole [Pyr-HEB] and (S)-(-)-N-(methyl-1 ‘-benzotriazolyl)-2-(alpha-hydroxyethyl)benzimidazole [Btz-HEB]. Subsequently, N-methyl maleimide interacts with the nucleophilic carbon of anthrone in a stepwise pathway, either from left-hand side or right-hand side, resulting in the generation of an enantioselective chiral product. A unique feature in the above reaction was that Pyr-HEB and Btz-HEB favoured the formation of SS-product and RR-product, respectively, with high enantioselectivity. The turnaround of enantioselectivity upon changing the catalyst has been attributed to the noncovalent interaction and steric orientation in the molecule during the intermediate reaction steps. An estimated value of degree of enantioselectivity, for both the catalysts, was obtained in accordance with the experimental findings.

Chiral polyureas of cinchona alkaloids were synthesized via repetitive Mizoroki-Heck (MH) coupling reaction. The Pd-catalyzed polycondensation of cinchona urea dimers6and aromatic diiodide7afforded the chiral polyureas (P1-P4). The catalytic activity of the chiral polymers was subsequently investigated. The asymmetric Michael addition of ketoesters to nitroolefins was successfully catalyzed by the polymeric organocatalysts (P1-P4) to give the corresponding Michael adducts with high catalytic activities and excellent enantionselectivities (up to >99% ee). The polymeric catalysts were insoluble in commonly used organic solvents. They were easily recovered and reused several times without any loss of the catalytic activity.

MgO has been shown to catalyze an almost quantitative hydrogen transfer from 2-octanol as the hydrogen donor to benzophenone to form benzhydrol, a useful intermediate product in the pharmaceutical industry. The hydrogen transfer from a series of alcohols to the carbonyl group of benzophenone, its ten derivatives, four polycyclic ketones, and 2-naphthyl phenyl ketone was carried out in liquid (LP) or vapor phase (VP). The dependence of reactivity on the structure of the hydrogen donor, reaction temperature, donor-acceptor ratio, amount of catalyst, and the type and position of substituents has been established. For both reaction modes, optimal conditions for selective synthesis of the alcohols were determined and side reactions were investigated. The results indicate that the reactivity of the ketone is suppressed by the presence of a methyl substituent in the ortho position to a much greater extent in LP mode. A scale-up was demonstrated in the liquid phase mode.

Sea grape (Caulerpa racemosa) is an edible green alga which contains a high amount of protein with a seafood flavor, which can be released via protein hydrolysis. Our present work was designed to determine the optimal concentration of palm sugar and carboxymethylcellulose (CMC) in sea grape protein hydrolysate sauce. The process optimization was performed to evaluate multiple parameters such as viscosity, color properties, and hedonic score. Five different levels of palm sugar and CMC were designed using a central composite design to yield sauce with a maximum hedonic score. We developed different mathematical models in this work, where viscosity, color properties (L*, a*, b*), and hedonic score were modeled using 2FI (two-factor interaction), quadratic, and linear models, respectively. The numerical optimization revealed that the predicted optimal solution was palm sugar and CMC concentration with generated viscosity, L*, a*, b*, and hedonic score of 0.893 poise, 23.296, 7.300, 19.565, and 3.522, respectively, and a desirability value of 0.839. GC-MS data associated with referred information represented that sea grape sauce had four compounds with a typical seafood flavor, namely, nonanal, hexanal, (E)-2-octenal, and octanoic acid; some native palm sugar flavors; and Maillard reaction products (MRP). Our study suggests that sauce is a potential value-added product from sea grape protein hydrolysate.

In view of the disadvantages of concentration polarization and trade-off effects in the application of membrane in desalination field, oxide-nano graphene oxide/polyamide (O-NGO/PA) loose intermediate layer and PA ultra-thin dense layer were introduced to fabricate PA/O-NGO/polyphenylene sulfide composite membrane with sandwich structure via multi-step interfacial polymerization (MS-IP) method. The selective permeation mechanism of ultrathin layer produced by different aqueous monomers (PIP and MPD) was studied, the effect of its physicochemical structure on the relief of concentration polarization phenomenon and the breakthrough of trade-off effect was analyzed. The ultra-thin and dense PA layer mainly played the role of interception and shortened the water molecular penetration path. In the retention test of metal salt solution, compared with the rough surface, it was found that the smooth surface was more conducive to the diffusion of intercepted metal ions into the feed solution, thus alleviating the concentration polarization phenomenon.
