Characterization and cytotoxic activity on glial cells of alkaloid-enriched extracts from pods of the plants Prosopis flexuosa and Prosopis nigra (Fabaceae)

Introduction: Prosopis spp. pods have shown to be a potential source of protein and energy in livestock. However, prolonged ingestion of some of these species produces neurological symptoms in ruminants. Objective: In the present study, the alkaloid content and the in vitro neurotoxic activity of alkaloid enriched-extracts from P. flexuosa and P. nigra pods were determined in order to elucidate the mechanism of animal poisoning caused by these species. Methods: The main alkaloids present in both extracts were analysed by high performance liquid chromatography-high resolution mass spectrometry (HPLC-HRMS). The cytotoxic activity of Prosopis alkaloid enriched-extracts in primary mixed glial cell culture was assessed by phase contrast microscopy and using neutral red, and lactate dehydrogenase (LDH) activity assays. Results: Juliprosine and juliprosopine were identified in P. flexuosa pods, while the absence of these alkaloids in P. nigra was confirmed. Both extracts (5-30 mu g/mL) induced in a dose dependent manner, morphological alterations, such as swelling, enlargement and detachment from the culture surface. Consistent with this, decrease in cell viability and release of LDH 48 hours after exposure, revealed that P. flexuosa pods was significantly more cytotoxic than P. nigra. Conclusions: In P. flexuosa pods, juliprosine and juliprosopine alkaloids were identified for the first time. Moreover, the present study suggests that the cytotoxic effect displayed by both extracts is due to its alkaloid content. However, the presence of piperidine alkaloids in P. flexuosa could explain the greater cytotoxicity on glial cells with respect to P. nigra that was not shown to contain these alkaloids.

Exploring the dicationic gemini surfactant for the generation of mesopores: a step towards the construction of a hierarchical metal-organic framework

The present study demonstrates a soft-template-assisted synthesis route to the preparation of a hierarchical microporous-mesoporous Cu-BTC metal-organic framework. The supramolecular assembly of di-cationic quaternary ammonium structure-directing agents cooperatively interacts with Cu-BTC framework coordination layers via a weak electrostatic interaction and self-assemble to form a Cu-BTC framework containing a hierarchical system of mesopores interconnected with micropores. Pore-size distribution measurements revealed that the produced metal-organic framework has a bimodal pore-size distribution consisting of micropores and mesopores. Materials prepared with the di-cationic structure-directing agent and swelling agent 1,3,5-trimethyl benzene showed further improvement in the mesopore diameter. The hierarchical Cu-BTC framework demonstrated higher CO2 uptake capacity and better oxidation activity in reactions involving large molecules, when compared to the conventional Cu-BTC framework.

2D Correlation Spectroscopy (2DCoS) Analysis of Temperature-Dependent FTIR-ATR Spectra in Branched Polyethyleneimine/TEMPO-Oxidized Cellulose Nano-Fiber Xerogels

Fourier transform infrared spectroscopy in attenuated total reflectance geometry (FTIR-ATR), combined with a 2D correlation analysis, was here employed to investigate temperature-induced spectral changes occurring in a particular type of novel cellulosic-based nano-material prepared using 2,2,6,6-tetramethyl-piperidine-1-oxyl (TEMPO) oxidized and ultra-sonicated cellulose nano-fibers (TOUS-CNFs) as three-dimensional scaffolds, and branched polyethyleneimine (bPEI) as cross-linking agent. The aim was to highlight the complex sequential events involving the different functional groups of the polymeric network, as well as to gain insight into the interplay between the amount of bPEI and the resulting sponge-like material, upon increasing temperature. In this framework, synchronous and asynchronous 2D spectra were computed and analyzed in three wavenumber regions (900-1200 cm(-1), 1500-1700 cm(-1) and 2680-3780 cm(-1)), where specific vibrational modes of the cellulosic structure fall, and over a T-range between 250 K and 340 K. A step-by-step evolution of the different arrangements of the polymer functional groups was proposed, with particular regard to how the cooperativity degree of inter- and intramolecular hydrogen bonds (HBs) changes upon heating. Information acquired can be useful, in principle, in order to develop a next-generation, T-sensitive novel material to be used for water remediation applications or for drug-delivery nano-vectors.

Mechanism and structure of the interaction of water-soluble pillar[5] arene and ibrutinib that enhances the anticancer activity of ibrutinib

Direct host-guest encapsulation of anticancer drugs by pillararenes is an effective approach to overcome their several disadvantages. In the present work, the potential application of water-soluble pillar[5]arene (WP5) on enhancing the bioactivity of ibrutinib (IBR) was evaluated. Nuclear magnetic resonance (NMR), ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, and fluorescence spectroscopy results showed that IBR could form a medium-strength complex with WP5 in solution (K = (2.13 +/- 0.10) x 10(4) M-1). Under this binding affinity, IBR could be slowly and steadily released from the complex. Studies on proton NMR and molecular modeling confirmed that the piperidine moiety of IBR entered the electron-rich cavity of WP5. CH-pi and hydrophobic interactions played major roles in IBR -WP5 binding. These amphiphilic complexes assembled into vesicles with an average diameter of 307.6 nm in aqueous solution. Some IBR were encapsulated in the vesicles. Such vesicles had a good stability (zeta-potential = -41.2 mV). Therefore, WP5 could effectively enhance the anticancer efficiency of IBR on CT26 cells although it had no special functions. (C) 2020 Elsevier B.V. All rights reserved.

Synthesis and Kinetics of Highly Substituted Piperidines in the Presence of Tartaric Acid as a Catalyst

Aim & Scope: The synthesis of highly substituted piperidine from the one-pot reaction between aromatic aldehydes, anilines and beta -ketoesters in the presence of tartaric acid as a catalyst has been investigated in both methanol and ethanol media at ambient temperature. Different conditions of temperature and solvent were employed for calculating the thermodynamic parameters and obtaining an experimental approach to the kinetics and mechanism. Experiments were carried out under different temperature and solvent conditions. Material and Methods: Products were characterized by comparison of physical data with authentic samples and spectroscopic data (IR and NMR). Rate constants are presented as an average of several kinetic runs (at least 6-10) and are reproducible within +/- 3%. The overall rate of reaction is followed by monitoring the absorbance changes of the products versus time on a Varian (Model Cary Bio-300) UV-vis spectrophotometer with a 10 mm light-path cell. Results: The best result was achieved in the presence of 0.075 g (0.1 M) of catalyst and 5 mL methanol at ambient temperature. When the reaction was carried out under solvent-free conditions, the product was obtained in a moderate yield (25%). Methanol was optimized as a desirable solvent in the synthesis of piperidine, nevertheless, ethanol in a kinetic investigation had none effect on the enhancement of the reaction rate than methanol. Based on the spectral data, the overall order of the reaction followed the second order kinetics. The results showed that the first step of the reaction mechanism is a rate determining step. Conclusion: The use of tartaric acid has many advantages such as mild reaction conditions, simple and readily available precursors and inexpensive catalyst. The proposed mechanism was confirmed by experimental results and a steady state approximation.

The Journey to In Vivo Synthetic Chemistry: From Azaelectrocyclization to Artificial Metalloenzymes

The goal of this account is to detail the steps taken by our group for the development of glycosylated artificial metal-loenzymes (GArMs), which we have used in our endeavors to develop examples of in vivo synthetic chemistry. To accomplish this, we have had to combine technologies developed over the course of a decade that range from protein ligation methodologies, identification of glycan-dependent targeting modules, and the development of functional biocatalysts. As an end result, we have begun to show the early framework for GArM complexes and their potential towards creating novel biotechnological tools and therapeutic applications.

Coupled electron and proton transfer in the piperidine drug metabolism pathway by the active species of cytochromes P450

Ring contraction of piperidine drugs by cytochrome P450 enzymes (P450s) is among the most important drug metabolisms for human beings. However, the underlying mechanism remains elusive and controversial even after decades of experimental study. Kohn-Sham density functional theory (KS-DFT) combined with multistate density functional theory (MSDFT) was used to explore the chemical nature of ring contraction of 2,2′,6,6′-tetramethylpiperidine (2,2′,6,6′-TMPi) mediated by the active species, Compound I of P450s. Our calculated results demonstrate that ring contraction is initiated by N-H bond activation. MSDFT combined with KS-DFT methods revealed that the N-H bond activation involves an initial tightly coupled electron-proton pair, essentially of hydrogen atom transfer (HAT) character prior to the diabatic crossing point, after which the mechanism is dominated by the concerted electron proton transfer (CEPT) product formation. The nascent N-centered radical intermediate undergoes electron tautomerism via rate-limiting homolytic C-C bond cleavage (ca. 21 kcal mol(-1)) to form a ring-opened, carbon-centered radical imine intermediate. The following barrierless C-N bond formation concomitant with hydroxyl rebound from the Fe-OH moiety forms the ring-contracted pyrrolidine product. To the best of our knowledge, this is the first application of MSDFT in P450 chemistry, and also the first comprehensive theoretical report on the ring contraction mediated by P450, in which the revealed new mechanism will undoubtedly promote relative rational drug design.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 379270-35-6.

Discovery, cocrystallization and biological evaluation of novel piperidine derivatives as high affinity Ls-AChBP ligands possessing alpha 7 nAChR activities

A series of novel pyridine-substituted piperidine derivatives were discovered as low nanomolar Is-AChBP ligands with alpha 7 nAChR partial agonism or antagonism activities. A high-resolution antagonist bound Ls-AChBP complex was successfully resolved with a classic Loop C opening phenomenon and unique sulfur-it interactions which deviated from our previous docking mode to a large extent. With the knowledge of the co-complex, 27 novel piperidine derivatives were designed and synthesized. The structure-activity relationships (SARs) of the aromatic and pyridine regions were well established and binding modes were illustrated with the help of molecular docking which indicated that interactions with Trp 143 and the water bridge are essential for the high binding affinities. Halogen bonding as well as the space around 5′- or 6′- position of the pyridine ring was also proposed to influence the binding conformation of the compounds. Notably, two enantiomers of compound 2 showed opposite functions toward alpha 7 nAChR and compound (S)-2 showed sub-nanomolar affinity (K-i = 0.86 nM) on Ls-AChBP and partial agonism (pEC(50) = 4.69 +/- 0.11,Emax = 36.1%) on alpha 7 nAChR with reasonable pharmacokinetics (PK) properties and fine ability of blood-brain-barrier (BBB) penetration. This study provided promising hits to develop candidates targeting nAChR-related CNS diseases. (C) 2018 Elsevier Masson SAS. All rights reserved.
