The push-pull electronic and steric effect of copper porphyrin catalysts on the cross-dehydrogenative coupling (CDC) reaction between the hydroxyl group of phenol substrates and C(sp(3))-H bond have been investigated. Results showed that copper porphyrin bearing electron-withdrawing, bulky steric hindrance or heteroatom of pyridyl groups could increase the catalytic activity in the reaction. 5,10,15,20-(tetrakis(4-pyridyl)porphyrin)copper (CuTPyP) was found the best among all tested catalysts. Phenol substrates bearing various functional groups afforded moderate to excellent yields (99%). Significantly, as compared to other tested copper porphyrins, CuTPyP not only exhibited remarkable higher activity but also could shorten the reaction time from 12 to 6 h.

The growing interest in the use of bio-oils requires a detailed understanding of its combustion chemical kinetics. Bio-oils contain a large variety of oxygenated organic species, in which substituted phenolic compounds are among the most significant fractions. Hence, accurate assessment of key reaction rate constants and systematically investigated the structural effect on the reactivity are critical. This work reports a systematic theoretical study of the hydrogen abstraction reactions from phenol, anisole, o-guaiacol, m-guaiacol, and p-guaiacol, which are considered as reference components in bio-oil surrogates. The hydrogen abstraction reactions by five different radicals (H/CH3/O(P-3)/OH/HO2) are investigated at ROCBS-QB3//M06-2X/cc-pVTZ level. The highpressure limit rate constants are computed via transition state theory with Eckart tunnelling and the 1-D hindered rotor approximation. Comparisons of site-specific hydrogen abstractions from the studied species with other related species are performed to understand the effects of the aromatic ring and side-chain substituent on hydrogen abstractions.

Natural product (NP) structures are a rich source of inspiration for the discovery of new biologically relevant chemical matter. In natural product inspired pseudo-NPs, NP-derived fragments are combined de novo in unprecedented arrangements. Described here is the design and synthesis of a 155-member pyrroquinoline pseudo-NP collection in which fragments characteristic of the tetrahydroquinoline and pyrrolidine NP classes are combined with eight different connectivities and regioisomeric arrangements. Cheminformatic analysis and biological evaluation of the compound collection by means of phenotyping in the morphological cell painting assay followed by principal component analysis revealed that the pseudo-NP classes are chemically diverse and that bioactivity patterns differ markedly, and are dependent on connectivity and regioisomeric arrangement of the fragments.

The chromenone core is an ubiquitous group in biologically active natural products and has been extensively used in organic synthesis. Fluorine-derived compounds, including those with a trifluoromethyl group (CF (3) ), have shown enhanced biological activities in numerous pharmaceuticals compared with their non-fluorinated analogues. 2-Trifluoromethylchromenones can be readily functionalized at the 8- and 7-positions, providing chromenones cores of high structural complexity, which are excellent precursors for numerous trifluoromethyl heterocycles.

Dulac, M; Nagarathinam, C; Dansette, P; Mansuy, D; Boucher, JL in [Dulac, Martin; Nagarathinam, Citra; Dansette, Patrick; Mansuy, Daniel; Boucher, Jean-Luc] Univ Paris 05, CNRS, UMR 8601, Lab Chim & Biochim Pharmacol & Toxicol, 45 Rue St Peres, F-75006 Paris, France published Mechanism of H2S Formation from the Metabolism of Anetholedithiolethione and Anetholedithiolone by Rat Liver Microsomes in 2019.0, Cited 30.0. The Name is 4′-Hydroxyacetophenone. Through research, I have a further understanding and discovery of 99-93-4.

The drug anetholedithiolethione (ADT) and its analogs have been extensively used as H2S donors. However, the mechanism of H2S formation from ADT under biologic conditions remains almost completely unknown. This article shows that only small amounts of H2S are formed during incubation of ADT and of its metabolite anetholedithiolone (ADO) with rat liver cytosol or with rat liver microsomes (RLM) in the absence of NADPH, indicating that H2S formation under these conditions is of hydrolytic origin only to a minor extent. By contrast, much greater amounts of H2S are formed upon incubation of ADT and ADO with RLM in the presence of NADPH and dioxygen, with a concomitant formation of H2S and para-methoxy-acetophenone (pMA). Moreover, H2S and pMA formation under those conditions are greatly inhibited in the presence of N-benzyl-imidazole indicating the involvement of cytochrome P450-dependent monooxygenases. Mechanistic studies show the intermediate formation of the ADT-derived 1,2-dithiolium cation and of the ADO sulfoxide during microsomal metabolism of ADT and ADO, respectively. This article proposes the first detailed mechanisms for the formation of H2S from microsomal metabolism of ADT and ADO in agreement with those data and with previously published data on the metabolism of compounds involving a C=S bond. Finally, this article shows for the first time that ADO is a better H2S donor than ADT under those conditions. SIGNIFICANCE STATEMENT Incubation of anetholedithiolethione (ADT) or its metabolite anetholedithiolone (ADO) in the presence of rat liver microsomes, NADPH, and O-2 leads to H2S. This article shows for the first time that this H2S formation involves several steps catalyzed by microsomal monooxygenases and that ADO is a better H2S donor than ADT. We propose the first detailed mechanisms for the formation of H2S from the microsomal metabolism of ADT and ADO.

Human Immunodeficiency Virus (HIV) damages the immune system and leads to the life-threatening acquired immunodeficiency syndrome (AIDS). Despite the advances in the field of antiretroviral treatment, HIV remains a major public health challenge. Nucleosides represent a prominent chemotherapeutic class for treating viruses, however their cellular uptake, kinase-mediated activation and catabolism are limiting factors. Herein, we report the synthesis and in vitro evaluation of stavudine (d4T) ProTides containing polyfluorinated aryl groups against two strains; HIV-1 (IIIB) and HIV-2 (ROD). ProTide 5d containing a meta-substituted pentafluorosulfanyl (3-SF5) aryl group showed superior antiviral activity over the parent d4T and the nonfluorinated analogue 5a. ProTide 5d has low nano-molar antiviral activity; (IC50=30 nM, HIV-1) and (IC50=36 nM, HIV-2) which is over tenfold more potent than d4T. Interestingly, ProTide 5d showed a significantly high selectivity indices with SI=1753 (HIV-1) and 1461 (HIV-2) which is more than twice that of the d4T. All ProTides were screened in wild type as well as thymidine kinase deficient (TK-) cells. Enzymatic activation of ProTide 5d using carboxypeptidase Y enzyme and monitored using both P-31 and F-19 NMR is presented.

An efficient and simple method for determining vanillin, methyl vanillin and ethyl vanillin in milk and dairy products was developed using a liquid-liquid extraction (LLE) procedure coupled to high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). Different extraction procedures were tested and optimised by spiking three vanillin compounds into a blank matrix in which none of any food additives were detected, and the extraction with acetonitrile solution and n-hexane as cleaning sorbent allowed an efficient recovery of 87.6-101.7% with RSDs less than 5%. The limit of detection (LOD) ranged from 6.2 to 20.1 mu g/kg. High sensitivity, accuracy and selectivity were found for the in-house validated method, which can eliminate the interferences from complicated matrices effectively, and fulfil the quality criteria for routine laboratory application for real samples. The developed method was then finally applied to screen the three analytes in 65 milk and dairy products including infant formula milk powders from local markets to check for compliance with Chinese Regulation. Concentrations of the total vanillin and ethyl vanillin ranged from 0.0323 to 246.3 mg/kg, which is within the limits of Chinese regulations.

Bimetallic silver and copper incorporated mesoporous MCM-48 (Ag/CuO/MCM-48) was synthesized by simple wet-impregnation method. The knowledge about its structural properties was gathered by means of Fourier transform-infrared, energy-dispersive X-ray, X-ray diffraction, field emission-scanning electron microscopy, transmission electron microscopy and Brunauer-Emmett-Teller analyses. The catalytic activity of Ag/CuO/MCM-48 was examined in the one-pot three-component reaction of 3-(1-methyl-1H-pyrrol-2-yl)-3-oxopropanenitrile, malononitrile and various aromatic aldehydes leading to novel pyran-pyrrole hybrid derivatives in reduced reaction times (5-10 min) and excellent yields (88-97%). Application of Ag/CuO/MCM-48 as a potent heterogeneous catalyst with good reusability up to five times, use of ethanol as an eco-compatible medium and chromatography-free work-up are some crucial green aspects of this procedure.
