Cu-Catalyzed Enantioselective Reductive Coupling of 1,3-Dienes and Aldimines

Catalytic chemo- and enantioselective generation of 1,3-disubstituted allyl-Cu complexes from a Cu-H addition to 1,3-dienes followed by in situ reactions with aldimines to construct homoallylic amines is presented. The method is distinguished by an unprecedented pathway to generate enantiomerically enriched allyl-Cu species, allowing reactions with a wide range of aldimines in high chemo-, site-, diastereo-, and enantioselectivity. Functionalization provides useful building blocks that are otherwise difficult to access.

Covalent cross-linked anion exchange membrane based on poly(biphenyl piperidine) and poly(styrene-b-(ethylene-co-butylene)-b-styrene): preparation and properties

Poly(biphenyl piperidine) and polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene were cross-linked to form a polymer backbone, piperidine as the ionic conducting group to improve the chemical stability of the anion exchange membrane. Results indicate that the cross-linked membranes could still retain more than 95% of ion conductivity after being soaked in 1-M KOH solution at 80 degrees C for 800 h, indicating that this cross-linked membrane exhibits good alkaline stability. The optimized microphase separation morphology could promote the ion transport (81.68 mS/cm, 80 degrees C). The cross-linked structure helped to restrain the swelling behavior. The membrane became flexible after cross-linking, which is beneficial to the fuel-cell assembly.

A desymmetrization-based approach to morphinans: application in the total synthesis of oxycodone

Here we report a total synthesis of the pharmacologically significant morphinan alkaloid, oxycodone. The centerpiece of the developed strategy features the first application of the Rovis desymmetrization of peroxyquinol in target-oriented total synthesis to access an optically active phenanthrene framework shared by the morphinans. A Stork-Ueno radical cyclization under photoredox conditions installed the all-carbon quaternary stereocenter, and a late-stage reductive detosylation with concomitant piperidine formation secured the core structure of the target molecule.

Molecular, supramolecular, DNA-binding and biological studies of piperazine and piperidine based dithiocarbamates of biocompatible copper

The reaction of dithiocarbamate ligands with CuCl2 center dot 2H(2)O gave the metal complexes of general formula Cu (S2CR)(2), where R = N(CH2)(4)N(Bn) (1), N(CH2)(4)N(MeO-Ph) (2), N(CH2)(4)N(C2H4OH) (3), N(CH2)(4)CHCH(Ph)(2) (4) and N(CH2)(4)CHC(OH)(Ph)(2) (5). The characterization was carried out by elemental analysis and spectro-scopic methods {FT-IR, UV-Visible, NMR (H-1 & C-13) and single crystal XRD}. The XRD data of three square planar complexes (1-3) revealed that 1 and 3 crystalize in monoclinic space group P2(1)/c and C2/c respectively, while 2 in the triclinic group P-1. A variety of interesting supramolecular motifs have been observed for these complexes ranging from 0 and 1-D chains to 2-D layers and 3-D networks. Moreover, DNA binding capability (determined by UV-Visible spectroscopy, cyclic voltammetry and viscometry) and biological activites (anti-oxidant, cytotoxicity and antileishmanial) of the synthesized metal complexes were also investigated. The complexes interacted with DNA base-pairs either through the intercalative or by electrostatic mode (complex 2 in CV experiment) with high binding constant values. As for biological activities are concerned, the synthesized compounds were found promising in all the assays.

Piperidine scaffold as the novel P2-ligands in cyclopropyl-containing HIV-1 protease inhibitors: Structure-based design, synthesis, biological evaluation and docking study

A series of potent HIV-1 protease inhibitors, containing diverse piperidine analogues as the P2-ligands, 4-substituted phenylsulfonamides as the P2′-ligands and a hydrophobic cyclopropyl group as the P1′-ligand, were designed, synthesized and evaluated in this work. Among these twenty-four target compounds, many of them exhibited excellent activity against HIV-1 protease with half maximal inhibitory concentration (IC50) values below 20 nM. Particularly, compound 22a containing a (R)-piperidine-3-carboxamide as the P2-ligand and a 4-methoxylphenylsulfonamide as the P2′-ligand exhibited the most effective inhibitory activity with an IC50 value of 3.61 nM. More importantly, 22a exhibited activity with inhibition of 42% and 26% against wild-type and Darunavir (DRV)-resistant HIV-1 variants, respectively. Additionally, the molecular docking of 22a with HIV-1 protease provided insight into the ligand-binding properties, which was of great value for further study.

L-lysine metabolism to N-hydroxypipecolic acid: an integral immune-activating pathway in plants

L-lysine catabolic routes in plants include the saccharopine pathway to alpha-aminoadipate and decarboxylation of lysine to cadaverine. The current review will cover a third L-lysine metabolic pathway having a major role in plant systemic acquired resistance (SAR) to pathogen infection that was recently discovered in Arabidopsis thaliana. In this pathway, the aminotransferase AGD2-like defense response protein (ALD1) alpha-transaminates L-lysine and generates cyclic dehydropipecolic (DP) intermediates that are subsequently reduced to pipecolic acid (Pip) by the reductase SAR-deficient 4 (SARD4). L-pipecolic acid, which occurs ubiquitously in the plant kingdom, is further N-hydroxylated to the systemic acquired resistance (SAR)-activating metabolite N-hydroxypipecolic acid (NHP) by flavin-dependent monooxygenase1 (FMO1). N-hydroxypipecolic acid induces the expression of a set of major plant immune genes to enhance defense readiness, amplifies resistance responses, acts synergistically with the defense hormone salicylic acid, promotes the hypersensitive cell death response and primes plants for effective immune mobilization in cases of future pathogen challenge. This pathogen-inducible NHP biosynthetic pathway is activated at the transcriptional level and involves feedback amplification. Apart from FMO1, some cytochrome P450 monooxygenases involved in secondary metabolism catalyze N-hydroxylation reactions in plants. In specific taxa, pipecolic acid might also serve as a precursor in the biosynthesis of specialized natural products, leading to C-hydroxylated and otherwise modified piperidine derivatives, including indolizidine alkaloids. Finally, we show that NHP is glycosylated in Arabidopsis to form a hexose-conjugate, and then discuss open questions in Pip/NHP-related research.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 34737-89-8, you can contact me at any time and look forward to more communication. COA of Formula: C13H17NO.

Efficient and Low Cytotoxicity Gene Carriers Based on Amine-Functionalized Polyvinylpyrrolidone

Non-viral vectors are a safety tool for gene therapy to deliver therapeutic genes. Among the different non-viral vectors, polyvinylpyrrolidone (PVP), a well-known hydrosoluble, neutral, and non-toxic polymer, satisfies the requirements and becomes a suitable candidate for gene delivery. In this study, we describe the preparation of polyvinylpyrrolidones decorated with pyrrolidine, piperidine, and piperazine groups, and evaluate them in vitro as non-viral gene carriers. The properties of these new systems are compared with those of hyperbranched polyethyleneimine (PEI) used as a positive control. Their ability to complex DNA at different N/P molar ratios, from 1:1 up to 10:1, was studied through agarose gel electrophoresis and dynamic light scattering. The resulting complexes (polyplexes) were characterized and evaluated in vitro with murine fibroblast (Swiss 3T3) as non-viral gene carriers, using luciferase as the reporter gene and a calcein cytocompatibility assay. All the copolymers condensed DNA to a particle average size between 100-400 nm when used at N/P ratios of 4:1 or higher. The copolymers with piperidine groups showed higher transfection efficiency than the pyrrolidine and piperazine modified copolymers, and even higher than the positive control of PEI at N/P ratios of 4:1 or higher. All the synthesized polyplexes from an aminated PVP displayed a general tendency of high cytocompatibility (75-95%) in comparison with the positive control PEI (55%).

Chemical and structural investigation of the paroxetine-human serotonin transporter complex

Antidepressants target the serotonin transporter (SERT) by inhibiting serotonin reuptake. Structural and biochemical studies aiming to understand binding of small-molecules to conformationally dynamic transporters like SERT often require thermostabilizing mutations and antibodies to stabilize a specific conformation, leading to questions about relationships of these structures to the bonafide conformation and inhibitor binding poses of wild-type transporter. To address these concerns, we determined the structures of Delta N72/Delta C13 and ts2-inactive SERT bound to paroxetine analogues using single-particle cryo-EM and x-ray crystallography, respectively. We synthesized enantiopure analogues of paroxetine containing either bromine or iodine instead of fluorine. We exploited the anomalous scattering of bromine and iodine to define the pose of these inhibitors and investigated inhibitor binding to Asn177 mutants of ts2-active SERT. These studies provide mutually consistent insights into how paroxetine and its analogues bind to the central substrate-binding site of SERT, stabilize the outward-open conformation, and inhibit serotonin transport.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 3056-33-5, in my other articles.
