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.

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.

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.

Hexafluoroisopropanol-Promoted Haloamidation and Halolactonization of Unactivated Alkenes

Pyrrolidine and piperidine derivatives bearing halide functional groups are prevalent building blocks in drug discovery as halides can serve as an anchor for post-modifications. In principle, one of the simplest ways to build these frameworks is the haloamination of alkenes. While progress has been made in this field, notably with the development of enantioselective versions, this reaction is still fraught with limitations in terms of reactivity. Besides, a major question remaining is to understand the mechanism at work. The formation of a haliranium intermediate is typically mentioned, but limited mechanistic evidence supports it. Reported here is an efficient metal- and oxidant-free protocol to achieve the haloamidation of olefins, promoted by hexafluoroisopropanol, along with a DFT investigation of the mechanism. These findings should guide the future development of more complex transformations in the field of halofunctionalization.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 13925-03-6, you can contact me at any time and look forward to more communication. HPLC of Formula: C7H10N2.

A simple method for the rapid synthesis of 2-amino-7,7-dimethyl-5-oxo-1,4-diaryl-hexahydroquinoline-3-carboxamide derivatives

Simple synthesis of oxoquinoline carboxamide derivatives via one-pot, multi-component reaction of enaminones derived from the addition of dimedone to various anilines with aromatic aldehydes and cyanoacetamide is described. Optimal reaction conditions for the synthesis of products were obtained, when EtOH/H2O (1:1) was used as the solvent at 80 degrees C, in the presence of piperidine as the catalyst. The reactions are completed within 5-25 min, in good to high yields (74-85%). This protocol involves Michael reaction, imine-enamine tautomerization, and cyclization sequences. The structures of products were deduced from their IR, mass, H-1 NMR, and C-13 NMR spectra. This method includes some important aspects including simple operation under mild conditions, easy accessibility of reactants, workup procedure, high atom economy, and the use of ethanol/water as a green media.

Alkaline polymer electrolyte fuel cells stably working at 80 degrees C

Alkaline polymer electrolyte fuel cells are a new class of polymer electrolyte fuel cells that fundamentally enables the use of nonprecious metal catalysts. The cell performance mostly relies on the quality of alkaline polymer electrolytes, including the ionic conductivity and the chemical/mechanical stability. For a long time, alkaline polymer electrolytes are thought to be too weak in stability to allow the fuel cell to be operated at elevated temperatures, e.g., above 60 degrees C. In the present work, we report a progress in the state-of-the-art alkaline polymer electrolyte fuel cell technology. By using a newly developed alkaline polymer electrolyte, quaternary ammonia poly (N-methyl-piperidine-co-p-terphenyl), which simultaneously possesses high ionic conductivity and excellent chemical/mechanical stability, the fuel cell can now be stably operated at 80 degrees C with high power density. The peak power density reaches ca. 1.5 W/cm(2) at 80 degrees C with PVC catalysts used in both the anode and the cathode. The cell works stably in a period of study over 100 h.
