A Mechanistic Paradigm for Broad-Spectrum Antivirals that Target Virus-Cell Fusion

LJ001 is a lipophilic thiazolidine derivative that inhibits the entry of numerous enveloped viruses at non-cytotoxic concentrations (IC50 <= 0.5 mu M), and was posited to exploit the physiological difference between static viral membranes and biogenic cellular membranes. We now report on the molecular mechanism that results in LJ001's specific inhibition of virus-cell fusion. The antiviral activity of LJ001 was light-dependent, required the presence of molecular oxygen, and was reversed by singlet oxygen (O-1(2)) quenchers, qualifying LJ001 as a type II photosensitizer. Unsaturated phospholipids were the main target modified by LJ001-generated O-1(2). Hydroxylated fatty acid species were detected in model and viral membranes treated with LJ001, but not its inactive molecular analog, LJ025. O-1(2)-mediated allylic hydroxylation of unsaturated phospholipids leads to a trans-isomerization of the double bond and concurrent formation of a hydroxyl group in the middle of the hydrophobic lipid bilayer. LJ001-induced O-1(2)-mediated lipid oxidation negatively impacts on the biophysical properties of viral membranes (membrane curvature and fluidity) critical for productive virus-cell membrane fusion. LJ001 did not mediate any apparent damage on biogenic cellular membranes, likely due to multiple endogenous cytoprotection mechanisms against phospholipid hydroperoxides. Based on our understanding of LJ001's mechanism of action, we designed a new class of membrane-intercalating photosensitizers to overcome LJ001's limitations for use as an in vivo antiviral agent. Structure activity relationship (SAR) studies led to a novel class of compounds (oxazolidine-2,4-dithiones) with (1) 100-fold improved in vitro potency (IC50<10 nM), (2) red-shifted absorption spectra (for better tissue penetration), (3) increased quantum yield (efficiency of O-1(2) generation), and (4) 10-100-fold improved bioavailability. Candidate compounds in our new series moderately but significantly (p <= 0.01) delayed the time to death in a murine lethal challenge model of Rift Valley Fever Virus (RVFV). The viral membrane may be a viable target for broad-spectrum antivirals that target virus-cell fusion. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

Pd-Catalyzed Decarboxylative Cycloaddition of Vinylethylene Carbonates with Isothiocyanates

An efficient route for formal [3 + 2] cycloaddition of vinylethylene carbonates with isothiocyanates was developed for the synthesis of 1,3-oxazolidine-2-thione derivatives. The zwitter-ionic pi-allyl palladium intermediates formed in situ by decarboxylation of VECs acted as the three-membered synthons. In this transformation, the C-N bond formation was selectively realized over the C-S bond formation.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 6704-31-0, you can contact me at any time and look forward to more communication. Computed Properties of C3H4O2.

A mixed anhydride approach to the preparation of sulfinate esters and allylic sulfones: Trimethylacetic p-toluenesulfinic anhydride

A reagent combination of toluenesulfinic acid and trimethylacetyl chloride affords a putative trimethylacetic p-toluenesulfinic anhydride. This reagent has been used to prepare a series of sulfinate esters from primary and secondary alcohols. In addition, the reagent was used to convert Baylis-Hillman substrates into allylic sulfones. Attempts to use the reagent to convert amines to sulfinamides were unsuccessful. In contrast, the use of 2-pyrrolidinone afforded N-p-toluenesulfinyl pyrrolidinone in 64% yield. The use of a chiral 4-benzy1-1,3-oxazolidinone or 4-benzyl-1,3-oxazolidine-2-thione led to the isolation of S-p-tolyl ptoluenethiosulfonate. (C) 2017 Elsevier Ltd. All rights reserved.

Comprehensive monitoring of MEA degradation in a post-combustion CO2 capture pilot plant with identification of novel degradation products in gaseous effluents

A pilot plant campaign was performed to study MEA degradation in CO2 capture conditions and anticipate potential degradation products emissions to the atmosphere in industrial case. Aqueous 30% wt MEA was cycled between absorption and regeneration steps during 1700 h in the presence of a synthetic flue gas containing 81% of N-2,14% of CO2, 5% of 02,97 ppm of NO, 9 ppm of SO2 and 5 ppm of NO2. Specific methods (sampling, sample conditioning and analysis) were developed to improve degradation products identification and to provide a quantification of targeted compounds in liquid phase and above all in absorber and stripper gas effluents. Especially, trace elements were detected in liquid phase thanks to Head Space Solid Phase MicroExtraction (HS-SPME) and liquid-liquid extraction with ChemElut cartridges and in gas phase thanks to adsorbent tubes of different type: Sep-Pak for aldehydes and ketones, Orbo 60 for N-nitrosodimethylamine, Tenax and active charcoal for non-specific adsorption. 32 degradation products were identified in liquid phase and 38 in gas phase, 17 of which for the first time, especially derivatives of pyridine and oxazolidine, 1H-pyrrole and a new nitrosamine, the N-nitroso-2-methyl-oxazolidine.

Enantioselective Synthesis of beta-Allenoates via Phosphine-Catalyzed and ZnI2-Promoted Preparation of Oxazolidines and Propargylamines Using Chiral Amines, 1-Alkynes, and Propiolates

Diphenylphosphinoethane (DPPE)-catalyzed and ZnI2-promoted in situ formation of oxazolidine, alkynyl zinc, and propargylamine intermediates from 1-alkynes, chiral (S)-diphenyl(pyrrolidin-2-yOmethanol, and propiolates gave the corresponding chiral (R)-beta-allenoates in 40-72% yield with up to >99% ee. The intermediate propargylamine was isolated in 50% yield and converted to give the beta-allenoate 10aa in 68% yield and 96% ee upon reaction with ZnI2. The results are discussed considering a mechanism involving oxazolidine and iminium ions formed in situ followed by addition of alkynyl zinc complex to produce the propargylamine that gives the corresponding allenoate via a 1,5 hydrogen shift in the presence of ZnI2.

Development of Antibacterial Agents Active against Drug-resistant Bacterial Pathogens Based on Total Synthesis of Nucleoside Natural Products

Natural products are a rich source for drug development. However, some biologically relevant natural products possess rather large, complex or labile chemical structures compared to synthetic drugs, which limits chemical modification in a process pursuing a structure-activity relationship. Here we describe the rational simplification of the muraymycins and caprazamycins class of nucleoside natural products to address the issue associated with their molecular complexity. First, the systematic structure-activity relationship (SAR) study of the muraymycins using an Ugi four-component reaction was investigated. Our SAR study of the muraymycins suggests a probable mechanism for inhibition of the MraY. The predicted binding model would provide further direction towards the design of potent MraY inhibitors. Next, function-oriented synthesis (FOS) of caprazamycins was investigated. Based on the conformation-activity relationship study of a series of analogs 36-38, we designed the oxazolidine-containing uridine derivatives 41-44 by restricting the conformation of 36-38. As a result, the tert-butyl ester derivatives 43 were found to be the most active against a range of bacterial strains containing VRE with a similar potency to the parent natural products. These studies provide a novel strategy for the development of a new type of antibacterial agent effective against drug-resistant bacteria.

Synthetic Route of 16251-45-9, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 16251-45-9 is helpful to your research.
