Comparative Transcriptome Analysis of Key Reductase Genes Involved in the 1-Deoxynojirimycin Biosynthetic Pathway in Mulberry Leaves and Cloning, Prokaryotic Expression, and Functional Analysis of MaSDR1 and MaSDR2

The alkaloid 1-deoxynojirimycin (DNJ) is the main bioactive ingredient in the hypoglycemic action of mulberry leaves (Morus alba L.). Our previous research clarified the upstream pathway from lysine to Delta 1-piperideine in the biosynthesis of DNJ in mulberry leaves, but the pathway and related reductase genes from Delta 1-piperideine to piperidine are still unclear. Here, a comparative transcriptome was used to analyze the transcriptome data of two samples (July and November) of mulberry leaves with significant differences in the content of DNJ and screen-related reductase genes. Results showed that expression levels of MaSDR1 and MaSDR2 were significantly and positively correlated with the content of DNJ (P < 0.05) in different seasons. MaSDR1 (GenBank accession no. MT989445) and MaSDR2 (GenBank accession no. MT989446) were successfully cloned and used for prokaryotic expression and functional analysis in vitro. MaSDR1 and MaSDR2 could catalyze the reaction of Delta 1-piperideine with the coenzyme NADPH to generate piperidine. The kinetic parameters of MaSDR1 and MaSDR2 indicated that MaSDR2 had a higher binding ability to Delta 1-piperideine than MaSDR1. This study provided insights into the biosynthesis of DNJ in mulberry leaves. A reaction mechanism is the microscopic path by which reactants are transformed into products.

One-pot synthesis of five substituted tetrahydropyridines using nano-Al2O3/BF3/Fe3O4 as a highly efficient nano-catalyst

Nano-Al2O3/BF3/Fe3O4 was synthesized as an efficient and reusable catalyst. The synthesized magnetic catalyst has been characterized by various methods such as FT-IR, FESEM, TGA, TEM, VSM, XRF, XRD and BET. This catalyst does not need special precautions for preparation, handling or storage, and it can be stored at an ambient temperature for months without losing its catalytic activity. Five-substituted tetrahydropyridines and their derivatives have an interesting class of pharmaceutical activities. Thus, the nano-Al2O3/BF3/Fe3O4 catalyst was used to prepare five-substituted tetrahydropyridines by one-pot multicomponent reactions of aromatic aldehydes, anilines and beta-keto-esters under solvent free conditions. The structure of products were studied by Fourier transform spectroscopy and nuclear magnetic resonance. The present protocol has notable advantages of easy purification, clean and convenient procedure and high yields for isolated products. In addition, this catalyst could be recycled several times without reduction in its admirable activity. [GRAPHICS] .

Novel Piperidine and 3,4-dihydro-2H-pyrrole Alkaloids from Tilia platyphyllos and Tilia cordata Flowers

Lime flowers, traditionally used for medical purposes for the treatment of symptoms of the common cold and mental stress, consist of the dried inflorescences including the floral bracts of Tilia cordata, Tilia platyphyllos, Tilia x vulgaris, ormixtures thereof. During phytochemical investigations, 6 different alkaloids-not described until now-were detected in T. cordata and T. platyphyllos flowers. They have been isolated and characterized as alkaloids with a dihydro-pyrrole and a piperidine substructure, respectively. Compounds 1a and 1b (tiliines A and B) are characterized as 2 diastereomers containing a 2-methyl-3,4-dihydro-2H-pyrrol-3-ol, connected via a C10 alkyl chain to a O-glucosylated hydroquinone moiety. Compounds 2a and 2b (tiliamines A and B) are diastereomers of a 2-methyl-substituted piperidin-3-ol, coupled via a C-9 alkyl chain again to an O-glucosylated hydroquinone moiety. Compounds 3a and 3b (tilacetines A and B) are 3-O-acetylated derivatives of tiliamines. Quantification of the 6 alkaloids by HPLC-ESI-qTOF analysis indicated the presence of all alkaloids in T. cordata flowers and T. platyphyllos flowers, bracts, and leaves, with tiliines A and B and tilacetines A and B being the major compounds. Acetone/water turned out be the best extraction solvent for the alkaloids, but ethanol and ethanol/water mixtures also can be used for effective extraction. Furthermore, the alkaloids are found in hot water extracts, which are typically used in the traditional medicine.

Electrochemical Oxidation of Organic Molecules at Lower Overpotential: Accessing Broader Functional Group Compatibility with Electron-Proton Transfer Mediators

CONSPECTUS: Electrochemical organic oxidation reactions are highly appealing because protons are often effective terminal electron acceptors, thereby avoiding undesirable stoichiometric oxidants. These reactions are often plagued by high overpotentials, however, that greatly limit their utility. Single-electron transfer (SET) from organic molecules generates high-energy radicalcations. Formation of such intermediates often requires electrode potentials far above the thermodynamic potentials of the reaction and frequently causes decomposition and/or side reactions of ancillary functional groups. In this Account, we show how electrocatalytic electron-proton transfer mediators (EPTMs) address this challenge. EPTMs bypass the formation of radical-cation intermediates by supporting mechanisms that operate at electrode potentials much lower (>= 1 V) than those of analogous direct electrolysis reactions. The stable aminoxyl radical TEMPO (2,2,6,6-tetramethylpiperidine N-oxyl) is an effective mediator for electrochemical alcohol oxidation, and we have employed such processes for applications ranging from pharmaceutical synthesis to biomass conversion. A complementary electrochemical alcohol oxidation method employs a cooperative Cu/TEMPO mediator system that operates at 0.5 V lower electrode potential than the TEMPO-only mediated process. This difference, which arises from a different catalytic mechanism, rationalizes the broad functional group tolerance of Cu/TEMPO-based aerobic alcohol oxidation catalysts. Aminoxyl mediators address long-standing challenges in the Shono oxidation, an important method for alpha-C-H oxidation of tertiary amides and carbamates. Shono oxidations are initiated by a high-potential SET step that limits their utility. Aminoxylmediated Shono-type oxidations have been developed that operate at much lower potentials and tolerate diverse functional groups. Analogous reactivity underlies alpha-C-H cyanation of secondary cyclic amines, a new method that enables efficient diversification of piperidine-based pharmaceutical building blocks and preparation of non-natural amino acids. Electrochemical oxidations of benzylic C-H bonds are commonly initiated by SET to generate arene radical cations, but such methods are again plagued by large overpotentials. Mediated electrolysis methods that promote hydrogen-atom-transfer (HAT) from benzylic C-H bonds to Fe-oxo species and phthalimide N-oxyl (PINO) support C-H oxygenation, iodination, and oxidative-coupling reactions. A complementary method merges photochemistry with electrochemistry to achieve amidation of C(sp(3))-H bonds. This unique process operates at much lower overpotentials compatible with diverse functional groups. These results have broad implications for organic electrochemistry, highlighting the importance of overpotential considerations and the prospects for expanding synthetic utility by using mediators to bypass high-energy outer-sphere electron-transfer mechanisms. Principles demonstrated here for oxidation are equally relevant to electrochemical reductions.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 3040-44-6 is helpful to your research. Computed Properties of C7H15NO.

Synthesis and antithrombotic activity of 1-benzyl-N ‘-benzylidenepiperidine-3-carbohydrazide derivatives

Platelet aggregation inhibition and interfering with clot formation are essential tools for antithrombotic therapy and there is a need for discovering new antithrombotic agents. In this study, we synthesized a series of benzylidenepiperidine-3-carbohydrazide derivatives (1f-11f), bearing various selected substituents on both the piperidine ring nitrogen and the hydrazide nitrogen. The synthesized compounds were characterized by FTIR, (HNMR)-H-1 spectroscopic techniques, CHN/O elemental analysis and electrospray ionization mass spectra. All new 1-benzyl-N0-benzylidenepiperidine-3-carbohydrazides were evaluated for their antiplatelet aggregation activities (against platelet aggregation induced by AA, ADP and collagen separately) and anticoagulant activities [protrombin time (PT) and partial thromboplastin time (PTT)]. Antiplatelet aggregation activity of the new derivatives was measured using human plasma on an APACT 4004 aggregometer. All the compounds were mainly effective on ADP pathway of platelet aggregation compared with collagen and AA pathways. The most potent compound on platelet aggregation induced by ADP is compound 2f with 87% aggregation inhibition activity at 0.5 mmol/l concentration. The synthesized compounds were further investigated for their anticoagulant action via the two PT and PTT models. They all showed higher PT and PTT values compared with the blank control sample. The most potent compounds are 5f, 6f, 7f and 1f. All compounds were obtained in good yield and further evaluated for their antiplatelet and anticoagulant activity.

Ethyl 2-acrylamido-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate as well as its correspondingbis-derivatives,5-10, with aliphatic linkers were synthesized, fully characterized, and tested as novel anticancer agents. The targeted compounds,5-10, were obtained by the Knoevenagel condensation reactions ofbis-o- or -p-aldehyde with a molar ratio of ethyl 2-(2-cyanoacetamido)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate of2in the presence of piperidine in excellent yields (93-98%). The in vitro anticancer activities of the prepared compounds were evaluated against HepG2, MCF-7, HCT-116, and BJ1 cells. Compounds7and9emerged as the most promising compounds, with IC(50)values of 13.5 and 32.2 mu g/ml, respectively, against HepG2 cells, compared with the reference drug doxorubicin (IC50: 21.6 mu g/ml). Real-time reverse-transcription polymerase chain reaction was used to measure the changes in expression levels of the COL10A1 and COL11A1, ESR1, and ERBB2, or AXIN1 and CDKN2A genes within the treated cells, as genetic markers for colon, breast, or liver cancers, respectively. Treatment of the colon cancer cells with compounds5,9, and10, or breast and liver cancers cells with compounds7,8,9, and10downregulated the expression of the investigated tumor markers. The DNA damage values (depending on comet and DNA fragmentation assays) increased significantly upon treatment of colon cancer cells with compounds5,9, and10, and breast and liver cells with compounds8,9, and10. The structure-activity relationship suggested that the increase of the chain of the alkyl linker increases the anticancer activity and the compounds withbis-cyanoacrylamide moieties are more active than those with one cyanoacrylamide moiety.
