Synthesis of (-)-Cytisine Using a 6-endo aza-Michael Addition

An asymmetric synthesis of (-)-cytisine has been achieved. The piperidine C-ring was formed using a stereodivergent intramolecular 6-endo aza-Michael addition. The B-ring was established by intramolecular pyridine N-alkylation. The absolute stereochemistry was established by an Evans acyl oxazolidinone enolate alkylation reaction that proceeded with an unexpected stereochemical outcome due to participation of the pyridine nitrogen lone pair.

Synthesis and characterization of a novel supported N-piperidine sulfamic acid on magnetic nanoparticles as a nanocatalyst for synthesis of pyrimido[4,5-c]pyridazines derivatives under ambient conditions and theoretical study on the mechanism using a DFT method

In this study, magnetic nanoparticles (Fe3O4 NPs) were employed as good support for N-piperidine sulfamic acid to prepare a novel nanocatalyst (SA-PPCA-Fe3O4 NPs). This nanocatalyst was then characterized by different techniques such as FT-IR, XRD, TGA, SEM, TEM and VSM. The catalytic activity of the SA-PPCA-Fe3O4 NPs was studied by one-pot preparation of pyrimido[4,5-c]pyridazines derivatives from three-component reactions of 1,3-dimethylthiobarbituric acid or 1,3-diethylthiobarbituric acid with different arylglyoxals and hydrazine monohydrate at ambient conditions. SA-PPCA-Fe3O4 NPs exhibited excellent advantages such as simplicity, high yields, short reaction time, easily separation using an external magnet, bio eco-friendly and recoverability and reusability with no remarkable loss of catalytic efficiency. In this work, density functional theory and modeling were reported to investigate of mechanism of the reaction. In fact, this study gives an insight into the mechanism of the pyrimido[4,5-c]pyridazines reaction in the presence of nanocatalyst of SA-PPCA-Fe3O4 NPs. Graphic abstract

Design, synthesis and evaluation of new classes of nonquaternary reactivators for acetylcholinesterase inhibited by organophosphates

A new series of nonquaternary conjugates for reactivation of both nerve agents and pesticides inhibited hAChE were described in this paper. It was found that substituted salicylaldehydes conjugated to aminobenzamide through piperidine would produce efficient reactivators for sarin, VX and tabun inhibited hAChE, such as L6M1R3, L6M1R5 to L6M1R7, L4M1R3 and L4M1R5 to L4M1R7. The in vitro reactivation experiment for pesticides inhibited hAChE of these new synthesized oximes were conducted for the first time. Despite they were less efficient than obidoxime, some of them were highlighted as equal or more efficient reactivators in comparison to 2-PAM. It was found that introduction of peripheral site ligands could increase oximes’ binding affinity for inhibited hAChE in most cases, which resulted in greater reactivation ability.

KN3014, a piperidine-containing small compound, inhibits auto-secretion of IL-1 beta from PBMCs in a patient with Muckle-Wells syndrome

NLRP3, an intracellular pattern recognition receptor, recognizes numerous pathogens and/or its own damage-associated molecules, and forms complexes with the adaptor protein ASC. These complexes constitute the NLRP3 inflammasome, a platform for processing interleukin (IL)-1 beta and/or IL-18. Several NLRP3 mutations result in constitutive activation of the NLRP3 inflammasome, causing cryopyrin-associated periodic syndrome (CAPS). To the best of our knowledge, small compounds that specifically inhibit inflammasome activation through the pyrin domain (PYD) have not yet been developed. This study describes an attempt to develop small compounds targeting the NLRP3 inflammasome. A core chemical library of 9,600 chemicals was screened against reconstituted NLRP3 inflammasome in a cell-free system with an amplified luminescence proximity homogeneous assay and a cell-based assay by human peripheral blood mononuclear cells (PBMCs). Inflammasome activation was evaluated by ASC-speck formation in human PBMCs, accompanied by IL-1 beta secretion and processing, and by using IL-1 beta -based dual operating luciferase (IDOL) mice. The activity of these compounds was evaluated clinically using PBMCs from a patient with Muckle-Wells syndrome (MWS), a type of CAPS, with an R260W mutation in NLRP3. Screening identified KN3014, a piperidine-containing compound targeting the interaction between NLRP3 and ASC through the PYD. KN3014 reduced ASC-speck formation in human PBMCs, luminescence from IDOL mice, and auto-secretion of IL-1 beta by PBMCs from the patient with MWS. These findings suggest that KN3014 may be an attractive candidate for treatment of MWS, as well as other NLRP3 inflammasomopathies.

Field-induced slow magnetic relaxation in low-spin S=1/2 mononuclear osmium(v) complexes

Photochemical reactions of (PPh4)[Os-VI(N)(L)(CN)(3)] (NO2-OsN) with piperidine and pyrrolidine afforded two osmium(v) hydrazido compounds, (PPh4)[Os-V(L)(CN)(3)(NNC5H10)] ([PPh4]1) and (PPh4)[Os-V(L)(CN)(3)(NNC4H8)] ([PPh4]2), respectively. Their structures consist of isolated, mononuclear distorted octahedral osmium anions that are well-separated from each other by PPh4+. Their low spin S = 1/2 and L = 1 ground state was confirmed by magnetometry and DFT calculations. Interestingly, both compounds exhibit slow magnetic relaxation under a bias dc-field. These osmium(v) complexes are potentially useful building-blocks for the construction of molecule-based architectures with interesting magnetic properties. In contrast, the structurally related (PPh4)[Os-III(L)(CN)(3)(NH3)] ([PPh4]3), which also has a low-spin S = 1/2 ground state but with a different electronic configuration (5d(5)), does not exhibit slow magnetic relaxation, due to the absence of any orbital moment (L = 0). Furthermore, the structurally different osmium(v) hydrazido compound reported by Meyer, [Os-V(tpy)(Cl)(2)(NNC5H10)](PF6) (4[PF6]), also does not exhibit slow magnetic relaxation due possibly to a change in magnetic anisotropy from axial for [PPh4]1 and [PPh4]2 to planar.

Metabolomic Study of Kidney Injury Induced by Antitubercular Drugs and Therapeutic Effect of Glutathione Based on Gas Chromatography-Mass Spectrometry

Histopathology and serum biochemical indicators (urea nitrogen and creatinine) were investigated to evaluate the kidney injury caused by the combination use of isoniazid (100 mg/kg/d, ig)) and rifampicin (100 mg/ (kg center dot d, ig)), which were used as anti-tuberculous drug. The endogenous metabolites extracted from kidney tissue were evaluated based on gas chromatography-mass spectrometry coupled with partial least squares-discriminant analysis and other multidimensional as well as unidimensional statistical methods. Glutathione, which was reported to protect tissue from damage caused by anti-tuberculosis drugs, was used to treat rats(250 mg/ (kg center dot d, iv)) with kidney damage. Biochemical indicators showed that creatinine and urea nitrogen increased (p < 0. 05) greatly after intragastrically administrated with isoniazid and rifampicin. In kidney, 31 endogenous metabolites were identified as potential biomarkers, including tyrosine, proline, uridine and palmitoleic acid, etc. All these results suggested that the combination use of isoniazid and rifampicin caused serious damage to kidney and disturbed the fatty acid metabolism, arginine and proline metabolism. In addition, glutathione reduced the level of serum urea nitrogen (p < 0. 05) obviously and alleviated proliferation of glomerular mesangium. These results indicated that glutathione had good therapeutic effects on kidney injury caused by antituberculous drug and significantly regulated the abundance of palmitoleic acid, 4.hydrobutyric acid, citrulline, gluconolactone, guanidinoacetic acid and piperidine acid in kidney.

Mass spectrometry for characterization of homologous piperidine alkaloids and their activity as acetylcholinesterase inhibitors

RationalePiperidine alkaloids from Senna spectabilis constitute a rare class of natural products with several biological activities. However, the absence of chromophores makes their structural elucidation by conventional methods a great challenge. In this context, mass spectrometry emerges as a powerful tool for metabolomics studies. MethodsThe piperidine alkaloids (-)-cassine and (-)-spectaline and the semisynthetic derivatives (-)-3-O-acetylcassine and (-)-3-O-acetylspectaline were investigated by electrospray ionization tandem mass spectrometry (ESI-MS/MS) in the positive mode and electron ionization mass spectrometry (EI-MS). ESI fragmentation studies were performed with a quadrupole time-of-flight instrument; N-2 was used as collision gas. The acetylcholinesterase inhibitory activity of the investigated compounds was evaluated by bioautography and microplate screening assays. ResultsESI-MS/MS and EI-MS provided valuable and complementary information about the structure of the piperidine compounds. Collision-induced dissociation experiments (MS/MS) revealed that neutral elimination of water or acetic acid is the major fragmentation pathway, which agrees with the stereochemistry proposed for (-)-cassine and (-)-spectaline and the semisynthetic derivatives (-)-3-O-acetylcassine and (-)-3-O-acetylspectaline. ConclusionsThe ESI-MS/MS and EI-MS studies allowed us to propose fragmentation mechanisms for piperidine alkaloids and derivatives. Therefore, mass spectrometry is an important tool for characterizing the structure of these compounds and for supporting further metabolomics studies.
