Catalytic Asymmetric Mannich-Type Reaction Enabled by Efficient Dienolization of alpha,beta-Unsaturated Pyrazoleamides dagger

Main observation and conclusion (E)-alpha,beta-Unsaturated pyrazoleamides undergo facile dienolization to furnish copper(I)-(1Z,3Z)-dienolates as the major in the presence of a copper(I)-(R)-DTBM-SEGPHOS catalyst and Et3N, which react with aldimines to afford syn-vinylogous products as the major diastereoisomers in high regio- and enantioselectivities. In some cases, the diastereoselectivity is low, possibly due to the low ratio of copper(I)-(1Z,3Z)-dienolates to copper(I)-(1Z,3E)-dienolates. (Z)-Allylcopper(I) species is proposed as effective intermediates, which may form an equilibrium with copper(I)-(1Z,3Z)-dienolates. Interestingly, the present methodology is a nice complement to our previous report, in which (E)-beta,gamma-unsaturated pyrazoleamides were employed as the prenucleophiles in the copper(I)-catalyzed asymmetric vinylogous Mannich-Type reaction and anti-vinylogous products were obtained. In the previous reaction, copper(I)- (1Z,3E)-dienolates were generated through alpha-deprotonation, which might form an equilibrium with (E)-allylcopper(I) species. Therefore, it is realized in the presence of a copper(I) catalyst that (E)-alpha,beta-unsaturated pyrazoleamides lead to syn-products and (E)-beta,gamma-unsaturated pyrazoleamides lead to anti-products. Finally, by use of (E)-beta,gamma-unsaturated pyrazoleamide, (E)-alpha,beta-unsaturated pyrazoleamide, (R)-DTBM-SEGPHOS, and (S)-DTBM-SEGPHOS, the stereodivergent synthesis of all four stereoisomers is successfully carried out. Then by following a three-step reaction sequence, all four stereoisomers of N-Boc-2-Ph-3-Me-piperidine are synthesized in good yields, which potentially serve as common structure units in pharmaceutically active compounds.

Antifungal properties of natural products from Pterocarya tonkinensis against phytopathogenic fungi

BACKGROUND In the search for new natural resources showing antifungal activity, we found that the methanol extract of Pterocarya tonkinensis (Fr.) Dode suppressed the disease development caused by fungi. The objectives of this article were (i) to isolate and identify the antifungal substances from the Pterocarya tonkinensis extract based on a bioassay-guided fractionation and (ii) to investigate their potential as a biocontrol agent with their antifungal activities in vitro and in vivo. RESULTS Eighteen compounds were identified from the methanol extract of Pterocarya tonkinensis, including two new natural products 1 and 2: 1, pterocaryalactone; 2, pterocaryafuranone; 3, (1S, 6R)-9-hydroxymegastigm-7-en-3-one; 4, (S)-dimethyl malate; 5, alpha-linolenic acid; 6-8, alpha-tetralones; 9, (R)-methyl-2-hydroxyl-3-phenyl-propanoate; 10, (E)-4-hydroxycinnamic acid methyl ester; 11-14, diarylheptanoids, and 15-18, pentacyclic triterpenoids. Based on the results of the in vitro antifungal assay, Magnaporthe oryzae and Phytophthora infestans were the most sensitive to the isolated compounds among the tested phytopathogenic fungi. When ten active compounds were applied onto plants at a concentration of 100 or 500 mu g mL(-1), compounds 1 and 8 effectively suppressed rice blast disease, and compounds 15 and 16 not only strongly reduced the development of blast on rice but also effectively controlled the development of late blight on tomatoes. CONCLUSION This is the first report to evaluate the in vitro and in vivo antifungal activities of the isolated compounds from a methanol extract of Pterocarya tonkinensis against phytopathogenic fungi, and our results suggest that Pterocarya tonkinensis and its substances can be used as a source to develop natural fungicides.

Production of new nanobiocatalysts via immobilization of lipase B from C. antarctica on polyurethane nanosupports for application on food and pharmaceutical industries

Nanobiocatalysts were produced via immobilization of CalB lipase on polyurethane (PU) based nanoparticles and their application on the synthesis of important industrial productswas evaluated. Nanoparticles of polyurethane functionalizedwith poly(ethylene glycol) (PU-PEG) were synthetized through miniemulsion polymerization and the addition of crosslinking agentswere evaluated. The nanoparticleswere employed as support for CalB and the kinetic parameterswere reported. The performance of newbiocatalystswas evaluated on the hydrolysis reaction of p-NPB and on the enantioselective hydrolysis of (R,S)-mandelic acid. The esterification reactionwas evaluated on the production of ethyl esters of Omega-3. The effect of poly( ethylene glycol) molar mass (400, 4000 or 6000 Da)on the biocatalyst activitywas also analyzed. The PU-PEG6000-CalB showed the highest value of the kinetic parameters, highlighting the high reaction rate. The addition of trehalose as crosslinking agent improved the thermal stability of the biocatalysts. PU-PEG400-CalB was the most active nanobiocatalyst, exhibiting a ethyl esters production of 43.72 and 16.83 mM.U -1 using EPA and DHA, respectively. The nanobiocatalyst was also applied in enantiomeric resolution ofmandelic acid, showing promising enantiomeric ratios. The results obtained in this work present alternative and sustainable routes for the synthesis of important compounds used on food and pharmaceutical industries. (c) 2020 Elsevier B.V.

Versatile, Multifunctional Block Copolymers for the Self-Assembly of Well-Defined, Nontoxic pDNA Polyplexes

In the field of systemically applied, nucleic acid-based drugs, polyplexes are interesting candidates for therapeutic systems. In this study, we synthesized a multifunctional triblock copolymer via reversible addition-fragmentation chain transfer (RAFT) block copolymerization. Due to three orthogonal reactive functionalities (an azide end group, a reactive disulfide block (P(PDSM)), and a reactive ester block (P(PFPMA))), the synthesized polymer system is highly adaptable and can be modified in a tailor-made fashion. After modification with N,N-dimethyl ethylendiamine (DMEDA), the synthesized cationic triblock copolymers form polyplexes with pDNA, even at low N/P ratios. The polyplexes can be stabilized further by cross-linking, having a size range of 113-151 nm in 10 mM NaCl, with high uniformity and low size distribution. measurements indicate a good shielding of the charged polyplex core. Additionally, no significant cytotoxicity of the polyplexes is found. First transfection experiments are positive, but the gene transfer efficiency needs to be improved further. Because of its high modifiability, the presented triblock copolymer system is a good candidate for an adjustable pDNA transport system.

NHC ligand-powered palladium-catalyzed carbonylative C-S bond cleavage of vinyl sulfides: efficient access to tert-butyl arylacrylates

A method for palladium-catalyzed carbonylative C-S bond activation of divinyl sulfides to synthesize numerous tert-(E)-butyl arylacry-lates under 1 bar of CO has been developed. Employing electron-rich NHC as the ligand, the electron-rich and stabilized palladium complex trend to oxidative addition to the relatively inert C-S bond and decreased the poisoning effect of sulfide and CO; a series of tert-(E)-butyl acrylates were obtained in moderate to good yields.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 3121-61-7. Quality Control of 2-Methoxyethyl acrylate.

A systematic review of the biodistribution of biomimetic high-density lipoproteins in mice

For the past two decades, biomimetic high-density lipoproteins (b-HDL) have been used for various drug delivery applications. The b-HDL mimic the endogenous HDL, and therefore possess many attractive features for drug delivery, including high biocompatibility, biodegradability, and ability to transport and deliver their cargo (e.g. drugs and/or imaging agents) to specific cells and tissues that are recognized by HDL. The b-HDL designs reported in the literature often differ in size, shape, composition, and type of incorporated cargo. However, there exists only limited insight into how the b-HDL design dictates their biodistribution. To fill this gap, we conducted a comprehensive systematic literature search of biodistribution studies using various designs of apolipoprotein A-I (apoA-I)-based b-HDL (i.e. b-HDL with apoA-I, apoA-I mutants, or apoA-I mimicking peptides). We carefully screened 679 papers (search hits) for b-HDL biodistribution studies in mice, and ended up with 24 relevant biodistribution profiles that we compared according to b-HDL design. We show similarities between b-HDL biodistribution studies irrespectively of the b-HDL design, whereas the biodistribution of the b-HDL components (lipids and scaffold) differ significantly. The b-HDL lipids primarily accumulate in liver, while the b-HDL scaffold primarily accumulates in the kidney. Furthermore, both b-HDL lipids and scaffold accumulate well in the tumor tissue in tumor-bearing mice. Finally, we present essential considerations and strategies for b-HDL labeling, and discuss how the b-HDL biodistribution can be tuned through particle design and administration route. Our metaanalysis and discussions provide a detailed overview of the fate of b-HDL in mice that is highly relevant when applying b-HDL for drug delivery or in vivo imaging applications.

Testing of diesel oil containing 10% (V/V) FAME and cetane package in terms of thermooxidative stability

Based on the results of tests and studies, the article presents the effect of the new Energocet (R) cetane-detergent additive on the oxidation stability and susceptibility to oxidation of B10 refined diesel oils according to the Rancimat PN-EN 15751: 2010 and PetroOXY PN 16091: 2011 method. Before starting the work, a literature review was carried out in terms of understanding this topic. Moving on to the research, the goals to be achieved were to compose a modern cetane-detergent package called Energocet (R) and show the effect of this cetane additive on the thermo-oxidative stability of the B10 type oils based on the results of the research on the peroxygen number and stability of the composed fuels. The research was carried out on the basis of raw materials, products and components available on the Polish fuel and biofuel market. In order to check the effectiveness and impact of the new Energocet (R) additive package on the quality of the composed fuels, one typical base diesel oil and two FAME components from different manufacturers were used in the research. In the research, for the preparation of the B10 base research fuels, one base A diesel oil and 2 types of methyl esters of rapeseed oil fatty acids (RME) marked as B and C were used. The work was of technological and analytical nature. Based on the results obtained from the tests of the Energocet (R) cetane detergent additive in diesel oils containing FAME in the amount of 10% (V/V) (B10), their thermo-oxidative stability was determined after three and six weeks of storage under test conditions. Additionally, the optimal dosing level of the Energocet (R) cetane-detergent package in the amount of 1500 mg/kg in B10 diesel oils with RME-B and RME-C was determined. The tendency of the improved tested fuels to generate free radicals during the six-week storage of samples at the temperature of 43 degrees C, determined as peroxide number, was also presented. The obtained results confirmed that the Energocet (R) cetane detergent additive has a positive effect on the quality parameters of B10 fuels, including thermo-oxidative stability.
