Chan-Lam cross-coupling reaction based on the Cu2S/TMEDA system

A catalyst based on the readily available Cu2S/TMEDA system using a stable copper(I) source was developed for the Chan-Lam cross-coupling reaction. The capability of the catalyst was demonstrated with 1H-benzo[d]imidazol-2(3H)-one, 1H-benzo[dlimidazole, and 1H-imidazole together with electron deficient, electron-rich, and sterically demanding boronic acids at room temperature in the presence of atmospheric oxygen to give the cross-coupling products in moderate to excellent yields. In addition, the coupling reaction of 1H-benzo[dlimidazole with several pinacol or neopentylglycol boronates indicated further potential of the catalyst. The reaction conditions tolerate the hydroxyl and bromo functional groups. The catalytic system also enables to synthesize the mono-N-substituted anilines from primary aliphatic amines. However, the two model compounds for the secondary and aromatic amines, piperidine and aniline, do not react. Two sterically demanding products with the restricted C-N bond rotation, synthesized by the N-arylation of 1H-benzo[d]imidazol-2(3H)-one with o-tolylboronic acid, enabled to confirm the atropisomers prepared by the Chan-Lam cross-coupling reaction. Furthermore, an example of one-pot Chan-Lam and Suzuki-Miyaura reaction has been reported. (C) 2017 Elsevier Ltd. All rights reserved.

Assessment of insecticidal responses of extracts and compounds of Drimys winteri, Lobelia tupa, Viola portalesia and Vestia foetida against the granary weevil Sitophilus granarius

Extracts and compounds from the Chilean plants canelo, Drimys winteri J.R. Forst. & G. Forst. (Winteraceae), tabaco del diablo, Lobelia tupa L. (Campanulaceae), huevil, Vestia foetida Hoffmans. (Solanaceae) and violeta, Viola portalesia Gay (Violaceae) were evaluated against Sitophilus granarius L. (Coleoptera: Curculionidae), one of the most widespread and destructive primary pests of stored cereals. Total extracts at concentrations of 2.5%(w)/(w), in diets, over 6-days, display insecticidal effects against S. granarius. D. winteri caused the mortality of 87.5% of insects; L. tupa 80%, V. foetida 56% whereas V. portalesia killed 45% of insects under the same conditions. In an effort to determine the active compounds, the extracts of Lobelia tupa and Drimys winteri were purified by preparative chromatography. The piperidine alkaloid lobelanidine was isolated from L. tupa and the drimane sesquiterpenes drimenin, drimenol and polygodial were isolated as the major components in the extract from D. winteri. The purified compounds compounds displayed insecticidal activity against S. granarius in a concentration/dependent-time manner (% mortality at 0.5%(w)/(w) over 6-days): polygodial 80%, drimenol 60%, lobelanidine 47%, and drimenin 20%. In agreement with these results, grains treated with polygodial showed greater protection against the feeding attack by the granary weevil. These results provide evidence of the importance of elements of the native Chilean flora as new potential sources of botanical pesticides for the insect pest control.

In silico study of the binding of two novel antagonists to the nociceptin receptor

Antagonists of the nociceptin receptor (NOP) are raising interest for their possible clinical use as antidepressant drugs. Recently, the structure of NOP in complex with some piperidine-based antagonists has been revealed by X-ray crystallography. In this study, a multi-flexible docking (MF-docking) procedure, i.e. docking to multiple receptor conformations extracted by preliminary molecular dynamics trajectories, together with hybrid quantum mechanics/molecular mechanics (QM/MM) simulations have been carried out to provide the binding mode of two novel NOP antagonists, one of them selective (BTRX-246040, formerly named LY-2940094) and one non selective (AT-076), i.e. able to inactivate NOP as well as the classical A mu- k- and delta-opioid receptors (MOP KOP and DOP). According to our results, the pivotal role of residue D130(3,32) (upper indexes are Ballesteros-Weinstein notations) is analogous to that enlighten by the already known X-ray structures of opioid receptors: binding of the molecules are predicted to require a slight readjustment of the hydrophobic pocket (residues Y131(3,33), M134(3,36), I219(5,43), Q280(6,52) and V283(6,55)) in the orthosteric site of NOP, accommodating either the pyridine-pyrazole (BTRX-246040) or the isoquinoline (AT-076) moiety of the ligand, in turn allowing the protonated piperidine nitrogen to maximize interaction (salt-bridge) with residue D130(3,32) of the NOP, and the aromatic head to be sandwiched in optimal pi-stacking between Y131(3,33) and M134(3,36). The QM/MM optimization after the MF-docking procedure has provided the more likely conformations for the binding to the NOP receptor of BTRX-246040 and AT-076, based on different pharmacophores and exhibiting different selectivity profiles. While the high selectivity for NOP of BTRX-246040 can be explained by interactions with NOP specific residues, the lack of selectivity of AT-076 could be associated to its ability to penetrate into the deep hydrophobic pocket of NOP, while retaining a conformation very similar to the one assumed by the antagonist JDTic into the K-opioid receptor. The proposed binding geometries fit better the binding pocket environment providing clues for experimental studies aimed to design selective or multifunctional opioid drugs.

Some novel piperidine analogues having strong alpha glucosidase inhibition

The idea of this study is based on the marvelous fact of nojirimycin and deoxy nojirimycin, naturally occurring from piperidine class and having their role as alpha glucosidase inhibitors. In the present work some hydroxy piperidine analogues have been synthesized and analysed for their hypoglycemic effect through glucosidase inhibition owing to the structural resemblance with nojirimycin. The activity was done by spectral absorbance analysis using acarbose as standard. Two analogues (I & IV) were found to pose excellent activity having 87.4 and 54.7% inhibition respectively, hence strengthening the idea of studying piperidine analogiues as glucosidase inhibitors due to structural similarity with nojirimycin.

Relebactam Is a Potent Inhibitor of the KPC-2 beta-Lactamase and Restores Imipenem Susceptibility in KPC-Producing Enterobacteriaceae

The imipenem-relebactam combination is in development as a potential treatment regimen for infections caused by Enterobacteriaceae possessing complex beta-lactamase backgrounds. Relebactam is a beta-lactamase inhibitor that possesses the diazabicyclooctane core, as in avibactam; however, the R1 side chain of relebactam also includes a piperidine ring, whereas that of avibactam is a carboxyamide. Here, we investigated the inactivation of the Klebsiella pneumoniae carbapenemase KPC-2, the most widespread class A carbapenemase, by relebactam and performed susceptibility testing with imipenem-relebactam using KPC-producing clinical isolates of Enterobacteriaceae. MIC measurements using agar dilution methods revealed that all 101 clinical isolates of KPC-producing Enterobacteriaceae (K. pneumoniae, Klebsiella oxytoca, Enterobacter cloacae, Enterobacter aerogenes, Citrobacter freundii, Citrobacter koseri, and Escherichia coli) were highly susceptible to imipenem-relebactam (MICs <= 2 mg/liter). Relebactam inhibited KPC-2 with a second-order onset of acylation rate constant (k(2)/K) value of 24,750 M-1 s(-1) and demonstrated a slow off-rate constant (k(off)) of 0.0002 s(-1). Biochemical analysis using time-based mass spectrometry to map intermediates revealed that the KPC-2-relebactam acyl-enzyme complex was stable for up to 24 h. Importantly, desulfation of relebactam was not observed using mass spectrometry. Desulfation and subsequent deacylation have been observed during the reaction of KPC-2 with avibactam. Upon molecular dynamics simulations of relebactam in the KPC-2 active site, we found that the positioning of active-site water molecules is less favorable for desulfation in the KPC-2 active site than it is in the KPC-2-avibactam complex. In the acyl complexes, the water molecules are within 2.5 to 3 angstrom of the avibactam sulfate; however, they are more than 5 to 6 angstrom from the relebactam sulfate. As a result, we propose that the KPC-2-relebactam acyl complex is more stable than the KPC-2-avibactam complex. The clinical implications of this difference are not currently known. Synthetic Route of 3040-44-6, 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 3040-44-6 is helpful to your research.

Asymmetric Synthesis of 2,3,6-Trisubstituted Piperidines via Baylis-Hillman Adducts and Lithium Amide through Domino Reaction

A convenient asymmetric synthesis of methyl (2S,3S,6R)-6-(4-fluorophenyl)-2-(4-hydroxyphenyl)-piperidine-3-carboxylate is described, starting from Baylis-Hillman adducts. The route involves a domino process: allylic acetate rearrangement, stereoselective IrelandClaisen rearrangement and asymmetric Michael addition, which provides a.-amino acid derivative with full stereochemical control. A subsequent chemoselective transformation of one of the side-chain groups allows an effective cyclization leading to biologically interesting polysubstituted piperidines in which the 2,6-aryl groups could be attached sequentially.
