Synthesis, characterization and evaluation of novel benzothiazole clubbed chromene derivatives for their anti-inflammatory potential

A series of chromene derivatives (5a-f) were prepared by multistep synthesis process using 2-[3-phenyl prop-2-ene nitrile] 1,3-benzothiazole and dimedone using piperidine as catalyst in ethanol. The reaction was found to proceed via Knoevenagel condensation of aldehydes with benzothiazole, followed by the elimination to afford the 2-(benzo[d]thiazol-2-yl)-3-(aryl)acrylonitrile, which then undergoes Michael addition with 5,5-dimethyl-1,3-cyclohexanedione, followed by intramolecular O-cyclization to give the products. The structures of all novel constructed derivatives were corroborated by elemental analysis and spectral data (FT-IR, H-1-NMR, C-13-NMR and Mass). Subsequently, the compounds were tested for their in-vivo anti-inflammatory activity. This study revealed that these synthesized derivatives tend to have significantly anti inflammatory activity and shall prove as structural templates in the design and development of new anti inflammatory drugs.

Selective synthesis of epichlorohydrin via liquid-phase allyl chloride epoxidation over a modified Ti-MWW zeolite in a continuous slurry bed reactor

The epoxidation of allyl chloride (ALC) to epichlorohydrin (ECH) with H2O2 using a piperidine (PI)-modified Ti-MWW catalyst (Ti-MWW-PI) in a continuous slurry reactor was investigated to develop an efficient reaction system for the corresponding industrial process. The reaction parameters, including solvent, reaction temperature, t-butanol/ALC mass ratio, ALC/H2O2 molar ratio, weight hourly space velocity of H2O2, and the addition amount of ammonia, were studied in detail to pursue high H2O2 conversion and ECH selectivity. A long catalytic lifetime of 244 h was achieved at high H2O2 conversion (>97.0%) and ECH selectivity (>99.8%) under optimized reaction conditions. The crystallinity was well maintained for the deactivated Ti-MWW-PI catalyst, which was regenerated by a combination of calcination and piperidine treatment.

Free energy profile and microkinetic modeling of base-catalyzed conjugate addition reaction of nitroalkanes to alpha,beta-unsaturated ketones in polar and apolar solvents

Michael reactions involving nitroalkanes and enones are important carbon-carbon bond formation reactions. These reactions are base-catalyzed, and during the past 15 years, the asymmetric version using bifunctional amino-thiourea organocatalyst has been developed. In this work, the reaction of nitromethane and 4-phenyl-3-buten-2-one, catalyzed by the methoxide ion and piperidine as bases, was investigated by theoretical calculations. We obtained the theoretical free energy profile and did a microkinetic analysis of the catalytic cycle. The direct reaction of the CH2NO2 (-) ion and the enone is very favorable, with a free energy of activation of 21.1 kcal mol(-1) in methanol solvent. However, the generated MS2 product works like an inhibitor of the catalysis, and the effective barrier in the catalytic cycle becomes 25.5 kcal mol(-1), leading to slow kinetics at room temperature. In the case of the reaction in apolar solvent (toluene), we found a pathway involving isomerization from the CH3NO2 reactant to the CH2NO2H species, and the latter makes a nucleophilic attack on the enone. Piperidine works like a bifunctional catalyst. In this case, the barrier is very high (32.5 kcal mol(-1)), indicating the importance of the polar environment to accelerate the reaction in the catalytic cycle.

Design, synthesis, and evaluation of novel anti-trypanosomal compounds

Human African trypanosomiasis (HAT) is a deadly neglected tropical disease caused by the protozoan parasite Trypanosoma brucei. During the course of screening a collection of diverse nitrogenous heterocycles, we discovered two novel compounds that contain the tetracyclic core of the Yohimbine and Corynanthe alkaloids, were potent inhibitors of T. brucei proliferation and T. brucei methionyl-tRNA synthetase (TbMetRS) activity. Inspired by these key findings, we prepared several novel series of hydroxyalkyl delta-lactam, delta-lactam, and piperidine analogs and tested their anti-trypanosomal activity. A number of inhibitors were more potent against T. brucei than these initial hits with one hydroxyalkyl delta-lactam derivative being 25-fold more effective in our assay. Surprisingly, most of these active compounds failed to inhibit TbMetRS. This work underscores the importance of verifying, irrespective of close structural similarities, that new compounds designed from a lead with a known biological target engage the putative binding site.

Poly(arylene alkylene)s with pendant N-spirocyclic quaternary ammonium cations for anion exchange membranes

Aromatic polymers functionalised with cycloaliphatic quaternary ammonium (QA) cations are currently emerging as base-stable anion exchange membranes (AEMs) for use in alkaline fuel cells and water electrolyzers. In the present work, we first prepared poly(biphenyl piperidine)s by superacid-mediated polycondensations, and then introduced different N-spirocyclic QA cations via cyclo-quaternisation of the piperidine rings. The resulting polymers and AEMs were free of diaryl ether linkages and benzylic C-H bonds, and showed very high thermal stability and hydroxide ion conductivity. Alkaline testing up to 120 degrees C implied that the alkaline stability of the spirocyclic cations was limited by distortions of the ring conformations caused by the rigid polymer backbone. As a consequence, the ring directly attached to the backbone degraded significantly faster by Hofmann -elimination than the pendant ring in the spirocyclic cations. These results provide valuable insights towards the molecular design of highly thermochemically stable AEMs functionalised with N-spirocyclic QA cations.

Methylpiperidinium Iodides as Novel Antagonists for alpha 7 Nicotinic Acetylcholine Receptors

The alpha 7 nicotinic acetylcholine receptor (nAChR) is expressed in neuronal and non-neuronal cells and is involved in several physiopathological processes, and is thus an important drug target. We have designed and synthesized novel piperidine derivatives as alpha 7 nAChR antagonists. Thus, we describe here a new series of 1-[2-(4-alkoxy-phenoxy-ethyl)]piperidines and 1-[2-(4-alkyloxy-phenoxy-ethyl)]-1-methylpiperidinium iodides (compounds 11a-11c and 12a-12c), and their actions on alpha 7 nAChRs. The pharmacological activity of these compounds was studied in rat CA1 hippocampal interneurons by using the whole-cell voltage-clamp technique. Inhibition of the choline-induced current was less for 11a-11c than for the methylpiperidinium iodides 12a-12c and depended on the length of the aliphatic chain. Those compounds showing strong effects were studied further using molecular docking and molecular dynamics simulations. The strongest and non-voltage dependent antagonism was shown by 12a, which could establish cation-pi interactions with the principal (C)side and van der Waals interactions with the complementary (-)-side in the alpha 7 nAChRs. Furthermore, compound 11a forms hydrogen bonds with residue Q115 of the complementary (-)-side through water molecules without forming cation-pi interactions. Our findings have led to the establishment of a new family of antagonists that interact with the agonist binding cavity of the alpha 7 nAChR, which represent a promising new class of compounds for the treatment of pathologies where these receptors need to be negatively modulated, including neuropsychiatric disorders as well as different types of cancer.

Formation of plasmon quenching dips greatly enhances O-1(2) generation in a chlorin e6-gold nanorod coupled system

Photodynamic therapy (PDT), as a noninvasive therapeutic method, has been actively explored recently for cancer treatment. However, owing to the weak absorption in the optically transparent windows of biological tissues, most commercial photosensitizers (PSs) exhibit low singlet oxygen (O-1(2)) quantum yields when excited by light within this window. Finding the best way to boost O-1(2) production for clinical applications using light sources within this window is, thus, a great challenge. Herein, we tackle this problem using plasmon resonance energy transfer (PRET) from plasmonic nanoparticles (NPs) to PSs and demonstrate that the formation of plasmon quenching dips is an effective way to enhance O-1(2) generation. The combination of the photosensitizer chlorin e6 (Ce6) and gold nanorods (AuNR) was employed as a model system. We observed a clear quenching dip in the longitudinal surface plasmon resonance (LSPR) band of the AuNRs when the LSPR band overlaps with the Q band of Ce6 and the spacing between Ce6 and the rods is within the acting distance of PRET. Upon irradiation with 660 nm continuous-wave laser light, we obtained a seven-fold enhancement in the O-1(2) signal intensity compared with that of a non-PRET sample, as determined using the O-1(2) electron spin resonance probe 2,2,6,6-tetramethyl-4-piperidine (TEMP). Furthermore, we demonstrated that the PRET effect is more efficient in enhancing O-1(2) yield than the often-employed local field enhancement effect. The effectiveness of PRET is further extended to the in vitro level. Considering the flexibility in manipulating the localized SPR properties of plasmonic nanoparticles/nanostructures, our findings suggest that PRET-based strategies may be a general way to overcome the deficiency of most commercial organic PSs in biological optically transparent windows and promote their applications in clinical tumor treatments.

Diastereoselective Syntheses of Spiro[indoline-3,4 ‘-pyridin]-2-yl Carbamates via AgOTf/Ph3P-Catalyzed Tandem Cyclizations of Tryptamine-Ynesulfonamides

Spiro[indoline-3,4′-piperidine] is a significant structural scaffold in numerous polycyclic indole alkaloids with a variety of bioactivities. In this study, a synthetic strategy was developed to access spiro[indoline-3,4′-pyridin]-2-yl carbamate via an AgOTf/ PPh3-catalyzed tandem cyclization of tryptamine-ynesulfonamides. The unique feature of this strategy is the efficient intermolecular capturing of the in situ generated spiroindoleninium intermediates with carbamates, leading to the diastereoselective syntheses of spiro[indoline-3,4’-pyridin]-2-yl carbamate derivatives. A broad scope of this cyclization was demonstrated by a variety of tryptamine-ynesulfonamide substrates and several carbamates. A plausible mechanism of this reaction was proposed.
