Stereoselective synthesis of the C18-C34 fragment of antascomicin A is described. Construction of the C27-C34 carbocycle moiety was achieved via catalytic Ferrier carbocylization and Johnson-Claisen rearrangement, which was converted to iodide 2 by use of asymmetric alkylation and Sharpless epoxidation as key transformations. Coupling of iodide 2 and sulfone 3 furnished the C18-C34 fragment.

Highly selective asymmetric synthesis of 2-hydroxy fatty acid methyl esters has been accomplished through chiral imide enolates. Five chiral oleic acid imides were prepared by reaction of oleic acid with pivaloyl chloride followed by reaction with five different lithiated chiral oxazolidinones including (R)-(+)-4-benzyl-2-, (S)-(-)-4-benzyl-2-, (4R, 5S)-(+)-4-methyl-5-phenyl-2-, (4S, SR)-(-)-4-methyl-5-phenyl-2-, and (R)-(+)-4-isopropyl-2-oxazolidinones in 88-92% yields. The chiral imides were reacted with NaN(Me3Si)2 at -78C to give enolates, which subsequently reacted with 2-(phenylsulfonyl)-3-phenyloxaziridine to give hydroxylated products in 78-83% yields. Methanolysis of the hydroxylated products with magnesium methoxide gave methyl 2-hydroxyoleate. Enantiomeric excesses (ee) of the products were determined to be very high (98-99% ee) by 1H nuclear magnetic resonance study after esterification of the hydroxy group with (S)-(+)-O-acetylmandelic acid. Enantioselective hydroxylation of other fatty acids including elaidic, petroselinic, vaccenic, and linoleic was evaluated under the similar conditions using (4R, 5S)-(+)-4-methyl-5-phenyl-2-oxazolidinone as a chiral auxiliary to give 98% ee values for all cases.

Antimicrobial peptides (AMPs), particularly those effective against methicillin-resistant Staphylococcus aureus (S. aureus) and antibiotic-resistant Pseudomonas aeruginosa (P. aeruginosa), are important alternatives to antibiotics. Typical peptide synthesis methods involving solid-phase sequential synthesis are slow and costly, which are obstacles to their more widespread application. In this paper, we synthesize peptides via ring-opening polymerization of alpha-amino acid N-carboxyanhydrides (NCA) using a transition metal initiator. This method offers high potential for inexpensive synthesis of substantial quantities of AMPs. Lysine (K) was chosen as the hydrophilic amino acid and alanine (A), phenylalanine (F), and leucine (L) as the hydrophobic amino acids. We synthesized five series of AMPs (i.e., P(KA), P(KL), P(KF), P(KAL), and P(KFL)), varied the hydrophobic amino acid content from 0 to 100%, and determined minimal inhibitory concentrations (MICs) against clinically important Gramnegative and Gram-positive bacteria and fungi (i.e., Escherichia coli (E. coli), P. aeruginosa, Serratia marcescens (S. marcescens), and Candida albicans (C. albicans). We found that P(K10F 7.5L7.5) and P(K10F15) show the broadest activity against all five pathogens and have the lowest MICs against these pathogens. For P(K10F7.5L7.5), the MICs against E. coli, P. aeruginosa, S. marcescens, S. aureus, and C. albicans are 31 mug/mL, 31 mug/mL, 250 mug/mL, 31 mug/mL, and 62.5 mug/mL, while for P(K10F15) the respective MICs are 31 mug/mL, 31 mug/mL, 250 mug/mL, 31 mug/mL, and 125 mug/mL. These are lower than the MICs of many naturally occurring AMPs. The membrane depolarization and SEM assays confirm that the mechanism of microbe killing by P(K10F 7.5L7.5) copeptide includes membrane disruption, which is likely to inhibit rapid induction of AMP-resistance in pathogens.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 3190-70-3. Product Details of 3190-70-3

Cortisol homeostasis has been linked to the pathogenesis of metabolic syndrome (MetS), since it stimulates hepatic gluconeogenesis and adipogenesis. MetS is classified as a constellation of health conditions that increase the risk of type 2 diabetes and cardiovascular disease. Intracellular cortisol levels are regulated by 11beta-hydroxysteroid dehydrogenase (type 1 and type 2) in a tissue dependent manner. The type 1 enzyme (11beta-HSD1) is widely expressed in glucocorticoid targeted tissues and is responsible for the conversion of cortisone to the active cortisol. Local reduction of cortisol regeneration presents a potential strategy for MetS treatment. Recently we disclosed the total synthesis of (+)-colletoic acid as a potent 11beta-HSD1 inhibitor. Herein, we describe our improved processing chemistry for the synthesis of the colletoic acid core to access a diverse number of derivatives for evaluation against 11beta-HSD1. The Evan’s chiral auxiliary was utilized to construct the acyclic precursor 12 to afford the acorane core 9 using a modified Heck reaction in excellent chemical yields. The colletoic acid core derivatives showed modest activity against 11beta-HSD1 and will serve for further biological evaluation.

1,3-Oxazolidine-2-one is an important heterocyclic ring participating in the chemical structure of many drugs. In this research, 22 new amide/sulfonamide/thiourea derivatives (1?22) were obtained by the reaction of (S)-4-(4-aminobenzyl)-2(1H)-1,3-oxazolidinone with 4-substituted benzoyl chlorides, 4-substituted benzene sulfonyl chlorides, and 4-substituted phenyl isothiocyanates. The structures of all synthesized compounds were clarified by FT-IR, NMR, and mass spectroscopic and elemental analysis techniques. The synthesized compounds were screened for their antimicrobial activity. Antimicrobial susceptibility and cellular physiology were evaluated using the microbroth dilution assay and the flow cytometry method. As a result, it was determined that compound 16 displayed better antimicrobial activity than chloramphenicol against Gram-positive bacteria, especially Staphylococcus aureus. In order to understand the mechanism of effect of the compounds on the cell membrane, fluorescence microscopy was used. Cell membrane damage of the Gram positive bacteria treated with compound 16 was observed as a result of intense staining with propidium iodide. In addition, genotoxicity, cytotoxicity, and absorption, distribution, metabolism, and excretion (ADME) parameters of compound 16 were examined and it was found as non-mutagenic and non-cytotoxic at the concentration at which it showed antimicrobial activity. According to the calculated ADME parameters and drug likeness scores, the compounds can be good drug candidates, especially compound 16.

Safety of (R)-4-Benzyl-2-oxazolidinone, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 102029-44-7, Name is (R)-4-Benzyl-2-oxazolidinone, molecular formula is C10H11NO2.

In an effort to find answers to the tantalizing questions about the absolute configurations of a group of long-known natural phenylpropanoids with very similar structures but different signs for the optical rotations, the compounds in question were synthesized in enantiomerically pure form using Evans asymmetric alkylation to generate the stereogenic centres with predefined absolute configurations. The 1H and 13C NMR spectra of the synthetic products were very consistent with those reported for their natural counterparts. In most cases, the optical rotations were also consistent with the corresponding data for the natural samples. The new findings not only allowed unequivocal assignments of the absolute configurations for the natural products, but also revealed that the configurations of closely related compounds from the same plant may be different.
