Target-Based Identification and Optimization of 5-Indazol-5-yl Pyridones as Toll-like Receptor 7 and 8 Antagonists Using a Biochemical TLR8 Antagonist Competition Assay

Inappropriate activation of endosomal TLR7 and TLR8 occurs in several autoimmune diseases, in particular systemic lupus erythematosus (SLE). Herein, the development of a TLR8 antagonist competition assay and its application for hit generation of dual TLR7/8 antagonists are reported. The structure-guided optimization of the pyridone hit 3 using this biochemical assay in combination with cellular and TLR8 cocrystal structural data resulted in the identification of a highly potent and selective TLR7/8 antagonist (27) with in vivo efficacy. The two key steps for optimization were (i) a core morph guided by a TLR7 sequence alignment to achieve a dual TLR7/8 antagonism profile and (ii) introduction of a fluorine in the piperidine ring to reduce its basicity, resulting in attractive oral pharmacokinetic (PK) properties and improved TLR8 binding affinity.

Cost-effective and handmade paper-based potentiometric sensing platform for piperidine determination

For the first time, a robust, rugged, and low-cost ion sensor based on potentiometric transduction is presented here for rapid determination of piperidine. A conventional filter paper is used as a substrate to establish the sensors after coating a carbon-ink layer on the surface of the filter paper to make it conductive. Poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) was used as an ion-to-electron transducer and deposited through drop-casting on the paper-based carbon electrode. The polymeric membranes were based on the incorporation of two types of electroactive materials, namely ion association complexes such as piperidinium phosphomolybdate (Pip/PMA) (sensor I), piperidinium phosphotungstate (Pip/PT) (sensor II), piperidinium tetraphenyl borate (Pip/TPB) (sensor III), and -cyclodextrin (-CD) ionophore (sensor IV) in a plasticized polyvinyl chloride (PVC) matrix. The sensors revealed Nernstian slopes of 60.2 +/- 0.5, 57.1 +/- 0.6, 56.2 +/- 0.8 and 54.2 +/- 0.6 mV per decade with linear concentration ranges begin from 5.1 x 10(-6), 7.4 x 10(-6), 3.1 x 10(-5) and 5.5 x 10(-6) M for sensors I, II, III and IV, respectively. The detection limits range from 0.32 to 0.66 g mL(-1) for all the proposed sensors with a response time <10 seconds. The sensors exhibited clear selectivity towards piperidinium ions over several common organic and inorganic cations. Repeatability, reproducibility and stability have been studied to evaluate the properties of the sensors. The sensors were successfully utilized for piperidine quantification in wastewater and human urine samples. The obtained results agreed well with the acceptable recovery percentage and were better than those obtained by other previously reported routine methods. Interested yet?

Palladium catalyzed reductive Heck coupling and its application in total synthesis of (-)-17-nor-excelsinidine

Monoterpene indole alkaloids, bearing a highly substituted piperidine ring, are a structurally diverse class of bioactive natural products, found in various parts of the world. Herein, we reported the construction of the key piperidine ring via palladium catalyzed reductive Heck coupling with a good syn selective manner, avoiding the usage of stoichiometric, highly toxic, air sensitive and moisture sensitive Ni(COD)(2). To further showcase the value of this methodology, we realized the total synthesis of the structurally unique zwitterionic monoterpene indole alkaloid (-)-17-nor-excelsinidine in 9 steps, in which the key ammonium-acetate connection (N4-C16) of (-)-17-nor-excelsinidine was constructed via oxidative coupling in excellent yield and high regioselectivity under NBS/pyridine from the enolate of geissoschizine.

On nitrogen fixation and residual nitrogen content in cellulosic pulps

Cellulosic material is capable of permanently retaining nitrogen compounds (mostly having amino functions), which is reflected in a residual nitrogen content (in the low per mille range to the low percent range) of some pulps and certain lab samples. Merely adsorptively bound compounds can be removed by mild acidic washing, but part of the nitrogen seems to be resistant and very tightly bound, and thus not accessible for removal by washing. Tertiary and aromatic amines are not retained in this way, but only primary and secondary amines. There is only a weak correlation between the firmly bound nitrogen and the carbonyl content in cellulosics (because of oxidative damage), so that possible aminal, Schiff base and enamine structures can hardly be relevant as major nitrogen sources. However, there is a very good linear correlation between the ISO brightness (chromophore content) in aged pulps and the residual nitrogen content. In particular the concentration of the cellulosic key chromophore 2,5-dihydroxy-[1,4]-benzoquinone (DHBQ) determines the permanent N-binding capacity of the pulp. DHBQ reacts very readily with primary and secondary amines under ambient conditions to 2,5-diamino-substituted [1,4]-benzoquinones, which have very low solubility (because of zwitterionic resonance contributions) and thus remain on/in the pulp. Examples of nitrogen fixation in pulps are the binding of piperidine (a common amine catalyst in derivatization reactions), amine degradation products of the cellulose solvent NMMO, dimethylamine in materials processed from the cellulose solvent DMAc/LiCl, imidazole (a degradation product of 1-alkyl-3-methylimidazolium ionic liquids), and of amino groups in proteins after enzymatic treatment. The nature of the respective DHBQ-amine addition compound has been verified by complete structure determination.

Synthetic cannabinoid receptor agonists: Analytical profiles and development of QMPSB, QMMSB, QMPCB, 2F-QMPSB, QMiPSB, and SGT-233

A diverse assortment of molecules designed to explore the cannabinoid receptor system and considered new psychoactive substances (NPS) have become known as synthetic cannabinoid receptor agonists (SCRAs). One group of SCRAs that has received little attention involves those exhibiting sulfamoyl benzoate, sulfamoyl benzamide, andN-benzoylpiperidine based structures. In this study, quinolin-8-yl 4-methyl-3-(piperidine-1-sulfonyl)benzoate (QMPSB), quinolin-8-yl 4-methyl-3-(morpholine-4-sulfonyl)benzoate (QMMSB), quinolin-8-yl 4-methyl-3-(piperidine-1-carbonyl)benzoate (QMPCB, SGT-11), quinolin-8-yl 3-(4,4-difluoropiperidine-1-sulfonyl)-4-methylbenzoate (2F-QMPSB, QMDFPSB, SGT-13), quinolin-8-yl 4-methyl-3-[(propan-2-yl)sulfamoyl]benzoate (QMiPSB, SGT-46), and 3-(4,4-difluoropiperidine-1-sulfonyl)-4-methyl-N-(2-phenylpropan-2-yl)benzamide (SGT-233) were extensively characterized (including data on impurities). The analytical profiles may be useful to researchers and scientists who deal with the emergence of NPS during forensic and clinical investigations. The detection of QMPSB was first published in 2016 but it is worth noting that Stargate International, a company originally formed to develop harm reduction solutions, were involved in the investigation and development of these six compounds for potential release between 2011 and early 2014. Whilst information on the prevalence of use of these particular compounds at the present time is limited, one of the key outcomes of the research performed by Stargate International reviewed here was to set the stage for the quinolin-8-yl ester head group that ultimately led to hybridization with anN-alkyl-1H-indole core to give SGT-21 and SGT-32, which became later known as PB-22 (QMPSB/JWH-018 hybrid) and BB-22, respectively, thus, opening the door to a range of SCRAs carrying the quinolin-8-yl head group from about 2012 onwards.

New 1,2,3-triazole based bis- and trisphosphine ligands: synthesis, transition metal chemistry and catalytic studies

The syntheses and transition metal chemistry of triazole-based bis- and tris-phosphines, 5-(diphenylphosphanyl)-1-(2-(diphenylphosphanyl)phenyl)-4-phenyl-1H-1,2,3-triazole (2), 5-(diphenylphosphanyl)-4(2-(diphenylphosphanyl)phenyl)-1-phenyl-1H-1,2,3-triazole (5), 1,4-bis(2-(diphenylphosphanyl)phenyl)1H-1,2,3-triazole (6) and 5-(diphenylphosphanyl)-1,4-bis(2-(diphenylphosphanyl)phenyl)-1H-1,2,3-triazole (7), are described. Bisphosphines 5 and 6 show versatile coordination behavior due to the presence of at least four donor atoms. The reactions of 5 and 6 with group VI metal carbonyl derivatives were found to be highly sensitive to the reaction conditions. Bisphosphine 5 upon treatment with [M (CO)4( piperidine)2] (M = Mo and W) yielded both P,P and P,N coordinated complexes [M(CO)4(5)] [M = Mo-kappa(2)-P,N (8); W-kappa(2)-P,N (9); Mo-kappa(2)- P,P (10); W-kappa(2)-P,P (11)], whereas 6 afforded only P,N coordinated complexes [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))CH}-kappa(2)-P,N}Mo(CO)(4)] (12) and [{o-Ph2P(C6H4){1,2,3N(3)C(o-Ph2P(C6H4))CH}-kappa(2)-P,N}W(CO)(4)] (13). The reactions of 5 with [M(COD)Cl-2] (M = Pd and Pt) yielded kappa(2)-P,P chelate complexes 14 and 15, respectively, whereas the treatment of 6 with [Pd(COD)Cl-2] at ambient temperature resulted in the formation of a rare fused six-membered PCP pincer complex [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))C}-kappa(3)-P, C,P}PdCl] (16). Similar reactions of 6 with [NiCl2(DME)] and [Pt(COD)Cl-2] in the presence of LiHMDS yielded [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))C}-kappa(3)-P,C,P} NiCl] (17) and [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H(4)))C}-kappa(3)-P,C,P}PtCl] (18), respectively. The reaction between 6 and [M(COD)Cl](2) (M = Rh and Ir) produced cationic complexes [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))CH}-kappa(2)-P,N}Rh(C8H12)]Cl (19) and [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))CH}-kappa(2)-P,N}Ir (C8H12)]Cl (20), respectively, whereas the reaction with [Rh(acac)(CO)(2)] resulted in a pincer complex [{o-Ph2P(C6H4){1,2,3-N3C(o-Ph2P(C6H4))C}-kappa(3)-P, C,P}Rh(CO)] (21). The structures of most of the compounds have been determined by single crystal X-ray analyses. The fused six-membered PCP palladium pincer complex 16 is found to be an excellent catalyst for the Mizoroki-Heck coupling reaction.

Hydrothermal liquefaction of protein-containing biomass: study of model compounds for Maillard reactions

The potential application of bio-oil production from nitrogen-containing biomass via hydrothermal liquefaction (HTL) may be limited due to high nitrogen content, making this product oil unsuitable for fuel-related uses. The Maillard reaction is expected to play a most significant role in the interaction between proteins and carbohydrates during the hydrothermal treatment. To evaluate the Maillard reaction network in this process, lactose, maltose, and lysine were employed as model substances and tested individually and in binary mixtures. HTL experiments were conducted at temperatures between 250 and 350 A degrees C and at 20 min reaction time. When treated individually, conversion of lysine leads to higher bio-oil yields (5-17 wt.%) than the model carbohydrates (6-10 wt.%) during HTL. In mixtures with carbohydrates, the measured bio-oil yields exceeded those obtained from conversion of the single substances (10-39 wt.%). Both yields and the relative nitrogen content of the bio-oil, increase with rising reaction temperature. The composition of the bio-oils obtained through HTL experiments was investigated in more detail: cyclopentenes and furfurals were obtained from disaccharide decomposition, piperidines and quinolines in the bio-oil originate from lysine, pyrazine and its derivatives are obtained from the mixture of lysine and disaccharides. A reaction scheme based on key chemical compounds accompanied with functional groups identified by FT-IR and NMR was developed to provide a better understanding of the Maillard reaction and its impact during HTL of protein-containing biomass.
