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.

Alterations of mitochondrial electron transport chain and oxidative stress induced by alkaloid-like alpha-aminonitriles on Aedes aegypti larvae

Aedes aegypti mosquitoes are responsible for dengue, chikungunya, and Zika virus transmission in tropical and subtropical areas around the world. Due to the absence of vaccines or antiviral drugs for human treatment, the majority of control strategies are targeted at Ae. aegypti elimination. Our research on mosquito control insecticidal agents has previously shown that the alkaloid girgensohnine and its analogues (alpha-aminonitriles) present in vitro acetylcholinesterase inhibition and in vivo insecticidal activity against Ae. aegypti. However, acetylcholinesterase inhibition may not be the only mechanism of action behind these effects. On this basis, the principal aim of this study was to elucidate the possible action mode of four alpha-aminonitriles on Ae. aegypti by studying other important enzymatic targets, such as mitochondrial electron transport chain complexes, catalase, and superoxide dismutase, key oxidative stress enzymes. Mitochondria were isolated from Ae. aegypti larvae by differential centrifugation, stored at -70 degrees C, and fragmented using ultrasound for 10 min. The effects of alpha-aminonitriles (1 to 4) over enzymatic activities were evaluated using concentrations of 8 nM, 2 mu M, 8 mu M, and 40 mu M. Results indicated that a-aminonitriles caused significant NADH dehydrogenase and succinate oxidase inhibition (similar to 44% at the highest concentration tested). Succinate dehydrogenase and cytochrome c oxidase activities were found to increase (162% and 106% at 40 mu M, respectively). It was also observed that these compounds produced catalase inhibition and thus prevented H2O2 reduction, which induced the formation of reactive oxygen species (ROS). Moreover, NBT assay showed that compounds 3 and 4 (with 2-(pyrrolidin-1-yl) acetonitrile as substituent) increased by approximately 50% the O-2(center dot-). concentration in the mitochondrial respiratory chain. It was concluded that the tested compounds act as complex I inhibitors by blocking electron transport and causing electron leak, possibly between complex I and III. Furthermore, a-aminonitriles inhibited catalase activity; compounds 1 and 2 (with piperidine fragment) inhibited glutathione reductase activity and further promoted the accumulation of ROS, which probably induced oxidative stress.

In silico and BSA binding study of some new biological analogs of 1,2,4-triazole pendant with azinane through microwave and conventional synthesis

Microwave and conventional techniques were employed to synthesize a novel array of compounds 7a-g with 1,2,4-triazole and piperidine rings having great biological importance. The microwave assisted method has a better operational scope with respect to time and yield comparative to the conventional method. H-1-NMR, C-13-NMR and IR techniques were employed to justify the structure of synthesized compounds. The antioxidant, butyrylcholinesterase inhibition and urease inhibition potential of every synthesized compound was evaluated. Every member of the synthesized series was found potent against mentioned activities. Compound 7g was the most active anti-urease agent having IC50 (mu M) value 16.5 +/- 0.09 even better than the thiourea with an IC50 (mu M) value of 24.3 +/- 0.24. The better urease inhibition potential of 7g was also elaborated and explained by docking and bovine serum albumin (BSA) binding studies.

Iridium-Catalyzed Highly Regioselective and Diastereoselective Allylic Etherification To Access cis-2,6-Disubstituted Dihydropyridinones

A highly regio- and diastereoselective method to access cis-2,6-disubstituted dihydropyridinones under mild conditions by an iridium-catalyzed allylic etherification is reported. cis-2,6-Disubstituted dihydropyridinones are important precursors for the de novo synthesis of the corresponding piperidine alkaloids and iminosugars. This strategy features a broad substrate scope, high yields, and excellent regio- and diastereoselectivities. A pi-allyl-Ir intermediate is involved in the mechanism. The strong A(1,3)-strain from the tosyl group may also favor the formation of cis-products in this transformation.

Chemically stable poly(meta-terphenyl piperidinium) with highly conductive side chain for alkaline fuel cell membranes

Poly(arylene piperidine)s (PAPs) backbones, which do not contain unstable ether bonds, was synthesized by one-pot, metal-free superacid-catalyzed polymerization for anion exchange membranes (AEMs) preparation. Meta-terphenyl as a monomer of polymer to regulate the morphology and properties of AEM was also used due to its spatially torsional configuration instead of the recently reported linear structure of peta-terphenyl. Long flexible hydrophilic chains were grafted onto poly(meta terphenyl piperidinium) (m-PTP) backbone to form four cationic functionalized side chains, promoting efficient transfer of OH- and optimizing the hydrophilic/hydrophobic microphase separation structure. The resulting AEM shows a high ion conductivity of 164 mS/cm (mPTP-TFPE-21) at 80 degrees C. Furthermore, stable piperidine cation and long alkyl spacer chain contributed to the excellent alkali stability of m-PTP-TFPE-TQA membrane which shows only 11.67% and 12.73% degradation in ion conductivity and IEC, respectively, after soaking in 2 M NaOH at 80 degrees C for 1500 h. The peak power density of the H-2/O-2 single cell using m-PTP-TFPE-14 is 269 mW/cm(2) at a current density of 540 mA/cm(2) at 80 degrees C.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 401566-79-8 is helpful to your research. SDS of cas: 401566-79-8.

The Energetic Viability of Delta(1)-Piperideine Dimerization in Lysine-derived Alkaloid Biosynthesis

Lys-derived alkaloids widely distributed in plant kingdom have received considerable attention and have been intensively studied; however, little is known about their biosynthetic mechanisms. In terms of the skeleton formation, for example, of quinolizidine alkaloid biosynthesis, only the very first two steps have been identified and the later steps remain unknown. In addition, there is no available information on the number of enzymes and reactions required for their skeletal construction. The involvement of the Delta(1)-piperideine dimerization has been proposed for some of the Lys-derived alkaloid biosyntheses, but no enzymes for this dimerization reaction have been reported to date; moreover, it is not clear whether this dimerization reaction proceeds spontaneously or enzymatically. In this study, the energetic viability of the Delta(1)-piperideine dimerizations under neutral and acidic conditions was assessed using the density functional theory computations. In addition, a similar type of reaction in the dipiperidine indole alkaloid, nitramidine, biosynthesis was also investigated. Our findings will be useful to narrow down the candidate genes involved in the Lys-derived alkaloid biosynthesis.

Diversity-oriented synthesis derived indole based spiro and fused small molecules kills artemisinin-resistant Plasmodium falciparum

BackgroundDespite numerous efforts to eradicate the disease, malaria continues to remain one of the most dangerous infectious diseases plaguing the world. In the absence of any effective vaccines and with emerging drug resistance in the parasite against the majority of anti-malarial drugs, the search for new drugs is urgently needed for effective malaria treatment.MethodsThe goal of the present study was to examine the compound library, based on indoles generated through diversity-oriented synthesis belonging to four different architecture, i.e., 1-aryltetrahydro/dihydro-beta -carbolines and piperidine/pyrrolidine-fused indole derivatives, for their in vitro anti-plasmodial activity. Trifluoroacetic acid catalyzed transformation involving tryptamine and various aldehydes/ketones provided the library.ResultsAmong all the compounds screened, 1-aryltetrahydro-beta -carbolines 2 and 3 displayed significant anti-plasmodial activity against both the artemisinin-sensitive and artemisinin-resistant strain of Plasmodium falciparum. It was observed that these compounds inhibited the overall parasite growth in intra-erythrocytic developmental cycle (IDC) via reactive oxygen species-mediated parasitic death and thus could be potential anti-malarial compounds.ConclusionOverall the compounds 2 and 3 identified in this study shows promising anti-plasmodial activity that can kill both artemisinin-sensitive and artemisinin-resistant strains of P. falciparum.
