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.

Red-Light-Mediated Barton-McCombie Reaction

A red-light-mediated Barton-McCombie reaction is described, in which chlorophyll a is used as a photocatalyst and tris(trimethylsilyl)silane or Hantzsch ester is used as the hydrogen source. The reaction can be performed with a set of easily available equipment and reagents, and a variety of linear and cyclic xanthates could be applied. In contrast to the traditional conditions, the reaction does not involve toxic organotin or an explosive radical initiator. The reaction mechanism was analyzed both by experiments and computation, and it was suggested that the radical chain mechanism initiated by excitation of complex followed by charge transfer is likely to be operative.

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

Adjustment of the Al siting in MCM-22 zeolite and its effect on alkylation performance of ethylene with benzene

It may be an important route to improve the alkylation performance of MCM-22 zeolite by regulating the Al siting during the synthesis, as the liquid alkylation of benzene with ethylene mainly occur on the acid sites in the surface pockets and supercages of MCM-22. Here, the Al siting has been successfully adjusted by introducing additional anion in the hydrothermal synthesis of MCM-22 using piperidine as the structure directing agent. The effect of the additional anion in the synthesis precursor on the physiochemical property, especially the Al siting, and alkylation performance of MCM-22 zeolite was investigated. The morphology of products tends to be irregular lamellar structure when Cl-, PO43-, or SO42- are present in the synthesis gel. Although H-MCM-22-PO43- and H-MCM-22-SO42- show less acid site concentration than H-MCM-22, they exhibit obviously higher conversion of ethylene than H-MCM-22. This can be attributed to that more Al species are oriented to T-2 sites located in the pockets or supercages by virtue of the presence of PO43- or SO42- in the synthesis gel. The novel synthesis strategy may provide an alternative way to modify the performances of MCM-22 and even other zeolites.

Multi-targeted drug design strategies for the treatment of schizophrenia

Introduction Schizophrenia is a complex psychiatric disease (or a conglomeration of disorders) manifesting with positive, negative and cognitive symptoms. The pathophysiology of schizophrenia is not completely known; however, it involves many neurotransmitters and their receptors. In order to treat schizophrenia, drugs need to be multi-target drugs. Indeed, the action of second and third generation antipsychotics involves interactions with many receptors, belonging mainly to aminergic GPCRs. Areas covered In this review, the authors summarize current concepts of schizophrenia with the emphasis on the modern dopaminergic, serotoninergic, and glutamatergic hypotheses. Next, they discuss treatments of the disease, stressing multi-target antipsychotics. They cover different aspects of design of multi-target ligands, including the application of molecular modeling approaches for the design and benefits and limitations of multifunctional compounds. Finally, they present successful case studies of multi-target drug design against schizophrenia. Expert opinion Treatment of schizophrenia requires the application of multi-target drugs. While designing single target drugs is relatively easy, designing multifunctional compounds is a challenge due to the necessity to balance the affinity to many targets, while avoiding promiscuity and the problems with drug-likeness. Multi-target drugs bring many benefits: better efficiency, fewer adverse effects, and drug-drug interactions and better patient compliance to drug regime.

Synthesis of Spirocyclic Piperidines by Radical Hydroarylation

Reported here are conditions for the construction of spirocyclic piperidines from linear aryl halide precursors. These conditions employ a strongly reducing organic photoredox catalyst in combination with a trialkylamine reductant to achieve formation of aryl radical species. Regioselective cyclization followed by hydrogen-atom transfer affords a range of complex spiropiperidines. This system operates efficiently under mild conditions without the need for toxic reagents or precious metals.

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.
