A conceptually novel sulfoxonium metathesis reaction between TMSOI and cost-effective DMSO-d(6) is developed for the efficient generation of a new trideuteromethylation reagent TDMSOI. The new reagent TDMSOI is produced highly efficiently by simply heating a mixture of TMSOI and DMSO-d(6) and directly used for subsequent trideuteromethylation in a one-pot operation. The preparative power of the new versatile reagent and the one-pot protocol is demonstrated by its use to install the -CD3 moiety into broad functionalities including phenols, thiophenols, acidic amines, and enolizable methylene units in high yield and at a useful level of deuteration (>87% D).

Biomass propagation for the production of active dry yeasts (ADY) is an economically important industrial process where cellular oxidative stress significantly limits yield and fermentative capacity in the final product. Oxidative stress affects macromolecular cell components, such as lipid and proteins, thus impairing many different cellular processes. Its detrimental effect is prevented and alleviated by complex signalling, detoxifying and protein protecting systems, which can be induced by antioxidant treatments. Here we validate the general beneficial effect of argan oil treatment in bench-top simulations of industrial yeast biomass propagation as an effective technological strategy to improve the biomass yield and fermentative capacity of ADY for subsequent wine making in grape must. We also identify biochemical and metabolic clues, and protein and enzymatic targets which contribute to the improved performance of yeasts in ADY production, which is relevant for future food industry applications.

Quinoline derivatives are attracting considerable interest due to their biological importance. In this paper, several 2-amino-4-aryl-6-(quinolin-2-ylthio)pyridine-3,5-dicarbonitrile derivatives are synthesized by adopting a one-pot reaction of quinoline-2-thione, aromatic aldehydes, and malononitrile in the presence of sodium hydroxide in absolute ethanol. The structures of these newly synthesized compounds were determined using different spectroscopic techniques, including elemental analyses, IR,H-1 NMR, and MS. The synthesized derivatives were screened for their antimicrobial and cytotoxic activities. Compounds4a,4b,4d, and4eexhibited promising antimicrobial activity compared to antibacterial and antifungal standard drugs. Additionally,4f,4d, and4gshowed potent cytotoxic activity against both MCF-7 and A549 cells with IC(50)values (6.39-9.3 mu M). Our molecular docking results of compound4fprove good binding affinity toward the three tested proteins as Jak2/STATA3 inhibition and are in accordance with the RT-PCR mRNA expressions of the compound against MCF-7 cells which downregulated the Jak2 and STAT3 genes, and this may be the proposed mode of action for anti-breast cancer activity.

Ersan, G; Apul, OG; Karanfil, T in [Ersan, Gamze; Karanfil, Tanju] Clemson Univ, Dept Environm Engn & Earth Sci, Anderson, SC 29625 USA; [Apul, Onur G.] Univ Massachusetts Lowell, Dept Civil & Environm Engn, Lowell, MA 01854 USA published Predictive models for adsorption of organic compounds by Graphene nanosheets: comparison with carbon nanotubes in 2019.0, Cited 32.0.

The Linear Solvation Energy Relationships (LSER) technique was applied in the present study for predicting models of organic compounds (OCs) adsorption by Graphene and Graphene oxide (GO), and the results were compared with those of multi-walled carbon nanotube (MWCNT) and single-walled carbon nanotube (SWCNT). Adsorption database of 38 OCs (28 aromatic and 10 aliphatic) for Graphene and 69 OCs (59 aromatic and 10 aliphatic) for GO were collected from the literature and our laboratory. The r(2) of the LSER models on the adsorption of aromatic OCs by Graphene and GO at three different equilibrium concentrations gradually increased up to OC molecular weight of 400 g/mol, after which a declining trend was observed for GO, while there was no visible change for Graphene. Among descriptors for all LSER models, V (molecular volume) and B (hydrogen bond accepting) for Graphene nanosheets (GNS) and carbon nanotubes (CNT) were the most significant descriptors (p values <= 0.05). B term had high value and was negatively correlated with adsorption of all OCs by Graphene (-1.24 to -9.45), GO (-0.55 to -9.31), SWCNT (-0.10 to -538) and MWCNT (-124 to -1.85). LSER successfully trained models for adsorption of OCs by GNS, and model coefficients were dependent on adsorbent type and OC properties. (C) 2018 Elsevier B.V. All rights reserved.

Human carboxylesterase 2 (hCES2A), one of the major serine hydrolases distributed in the small intestine, plays a crucial role in hydrolysis of ester-bearing drugs. Accumulating evidence has indicated that hCES2A inhibitor therapy can modulate the pharmacokinetic and toxicological profiles of some important hCES2A-substrate drugs, such as the anticancer agent CPT-11. Herein, a series of indanone-chalcone hybrids are designed and synthesized to find potent and highly selective hCES2A inhibitors. Inhibition assays demonstrated that most indanone-chalcone hybrids displayed strong to moderate hCES2A inhibition activities. Structure-hCES2A inhibition activity relationship studies showed that introduction of a hydroxyl at the C4′ site and introduction of an N-alkyl group at the C6 site were beneficial for hCES2A inhibition. Particularly, B7 (an N-alkylated 1-indanoneechalcone hybrid) exhibited the most potent inhibition on hCES2A and excellent specificity (this agent could not inhibit other human esterases including hCES1A and butyrylcholinesterase). Inhibition kinetic analyses demonstrated that B7 potently inhibited hCES2A-mediated FD hydrolysis in a mixed inhibition manner, with a calculated K-i value of 0.068 mu M. Furthermore, B7 was capable of inhibiting intracellular hCES2A in living cells and displayed good metabolic stability. Collectively, our findings show that indanone-chalcone hybrids are good choices for the development of hCES2A inhibitors, while B7 is a promising candidate for the development of novel anti-diarrhea agents to ameliorate irinotecan-induced intestinal toxicity.

In the current study, a new series of pyrazole derivatives4a-d,5a-dand6a-dpossessing 1,5,10,10a-tetrahydrobenzo[g]quinoline-3-carbonitrile moiety were synthesized by treating chalcones (3a-d) with hydrazine monohydrate/acetic anhydride, hydrazine monohydrate/formic acid and 4-chlorophenylhydrazine in ethanol, respectively. These reactions proceeded smoothly with satisfactory yields, and the obtained compounds were characterized using FTIR,H-1-NMR,C-13-NMR and elemental analyses. All the synthesized compounds were subjected to antibacterial activity againstBacillus subtilis,Staphylococcus aureus,Escherichia coli, andPseudomonas aeruginosabacteria and molecular docking studies. The antibacterial studies showed that all compounds exhibited good to excellent antibacterial activity against the tested bacterial strains. The structure-activity relationship studies revealed that the compounds3b,4b,5band6bbearing a chlorine atom at the para position of the phenyl group attached to pyrazole moiety in displayed the highest antibacterial activity against all the tested bacteria exceeding the standard drug ampicillin. Moreover, the molecular docking results showed that the highest scores docking have been obtained from the most active antibacterial compounds3b,3d,4b,4d,4c,5band6bwith good energy binding score within the active site of topoisomerase II DNA gyrase enzymes (PDB ID: 2XCS), suggesting that they can act by the inhibition of DNA replication. These compounds are auspicious candidates as antibacterial agents that would deserve further investigations.

Hydrogen atom transfer (HAT) hydrogenation has recently emerged as an indispensable method for the chemoselective reduction of unactivated alkenes. However, the hitherto reported systems basically require stoichiometric amounts of silanes and peroxides, which prevents wider applications, especially with respect to sustainability and safety concerns. Herein, we report a silane- and peroxide-free HAT hydrogenation using a combined cobalt/photoredox catalysis and ascorbic acid (vitamin C) as a sole stoichiometric reactant. A cobalt salophen complex is identified as the optimal cocatalyst for this environmentally benign HAT hydrogenation in aqueous media, which exhibits high functional-group tolerance. In addition to its applicability in the late-stage hydrogenation of amino-acid derivatives and drug molecules, this method offers unique advantage in direct transformation of unprotected sugar derivatives and allows the HAT hydrogenation of unprotected C-glycoside in higher yield compared to previously reported HAT hydrogenation protocols. The proposed mechanism is supported by experimental and theoretical studies. Hydrogen atom transfer (HAT) hydrogenation of alkenes usually requires stoichiometric silanes and peroxides. Here, the authors report a silane- and peroxide-free HAT hydrogenation method using a combined cobalt/photoredox catalysis and vitamin C as a sole stoichiometric reactant.

Taxol (paclitaxel) is a very widely used anticancer drug, but its commercial sources mainly consist of stripped bark or suspension cultures of members of the plant genus Taxus. Taxol accumulates as part of a complex mixture of chemical analogs, termed taxoids, which complicates its production in pure form, highlighting the need for metabolic engineering approaches for high-level Taxol production in cell cultures or microbial hosts. Here, we report on the characterization of acyl-activating enzymes (AAEs) that catalyze the formation of CoA esters of different organic acids relevant for the N-substitution of the 3-phenylisoserine side chain of taxoids. On the basis of similarities to AAE genes of known function from other organisms, we identified candidate genes in publicly available transcriptome data sets obtained with Taxus ? media. We cloned 17 AAE genes, expressed them heterologously in Escherichia coli, purified the corresponding recombinant enzymes, and performed in vitro assays with 27 organic acids as potential substrates. We identified TmAAE1 and TmAAE5 as the most efficient enzymes for the activation of butyric acid (Taxol D side chain), TmAAE13 as the best candidate for generating a CoA ester of tiglic acid (Taxol B side chain), TmAAE3 and TmAAE13 as suitable for the activation of 4-methylbutyric acid (N-debenzoyl-N-(2-methylbutyryl)taxol side chain), TmAAE15 as a highly efficient candidate for hexanoic acid activation (Taxol C side chain), and TmAAE4 as suitable candidate for esterification of benzoic acid with CoA (Taxol side chain). This study lays important groundwork for metabolic engineering efforts aimed at improving Taxol production in cell cultures.
