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.

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.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 4395-98-6, you can contact me at any time and look forward to more communication. Recommanded Product: 4395-98-6.

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.

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.

Kinetics and mechanism of counterionic salt-catalysed piperidinolysis of anionic phenyl salicylate in the presence of cationic-nonionic mixed micelles

The quantitative correlation of counterion-affinity to aqueous hexadecyltrimethylammonium bromide (HDAB, cationic micelles/nanoparticles) and the counterion-induced HDAB micellar growth, in the presence of different amounts of poly(ethylene glycol hexadecyl ether) (C16E20, nonionic surfactant), was achieved by the use of a semi-empirical kinetic (SEK) method. The values of the ratio of cationic HDAB, as well as mixed HDAB-C16E20, micellar binding constants of X and Br, K-X/K-Br (= K-X(Br) or R-X(Br)) for X = 4-ClC6H4CO2-, were obtained by the SEK method. The concentration range (0.006-0.015 M) of pure HDAB was found to have no influence on the values of K-X(Br) or R-X(Br). These observations were also recorded upon addition of a nonionic surfactant, C16E20, in an aqueous solution of HDAB. The mean value of K-X(Br) or R-X(Br) obtained in the presence of pure HDAB (K-X(Br) or R-X(Br) = 50.3) is 2.3 times larger than that in the presence of mixed HDAB-C16E20 (K-m(X)Br or R-m(X)Br = 21.7). From rheometric measurements of aqueous HDA(+)/4-ClC6H4CO2- with 0.015 M HDAB, single symmetric maxima (at both 25 and 35 degrees C) were obtained at [4-ClC6H4CO2Na] = 0.03 M. This is evidence for the existence of wormlike micelles/nanoparticles. However, the absence of a maximum in rheometric data for aqueous HDA(+)/C16E20/4-ClC6H4CO2- with 0.015 M HDAB and 0.006 M C16E20 at various [4-ClC6H4CO2Na] revealed the existence of spherical micelles.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 106-52-5, in my other articles.

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.

Genetic Relationships among Different Chemotypes of Lupinus sulphureus

Lupines (Lupinus spp.) are a common plant legume species found on western U.S. rangelands. Lupinus spp. may contain quinolizidine and/or piperidine alkaloids that can be toxic and/or teratogenic to grazing livestock. Alkaloid profiles may vary between and within a species. The objectives of this study were to (1) further explore the characteristic alkaloid profiles of Lupinus sulphureus using field collections and (2) explore the phylogenetic relationship of the different populations and chemotypes of L. sulphureus using the amplified fragment length polymorphism method of DNA fingerprinting, thus providing possible explanations to the phenomena of multiple chemotypes within a species. A total of 49 accessions of L. sulphureus were classified into seven chemotypes. The DNA profiles showed that one L. sulphureus chemotype, chemotype A, is genetically divergent from the other chemotypes of L. sulphureus, suggesting that it represents an unresolved lupine taxon, possibly a new lupine species. Additionally, the different chemotypes of L. sulphureus represented different genetic groups, as shown by Bayesian cluster analysis and principle component analysis.

Identification of a new series of benzothiazinone derivatives with excellent antitubercular activity and improved pharmacokinetic profiles

Nitrobenzothiazinone (BTZ) is a promising scaffold with potent activity against M. tuberculosis by inhibiting decaprenylphosphoryl-beta-d-ribose 2-oxidase (DprE1). But unfavorable durability poses a challenge to further development of this class of agents. Herein, a series of BTZs bearing a variety of different substituents at the C-2 position were designed and synthesized. Compounds were screened for their antimycobacterial activity against Mycobacterium tuberculosis H37Ra and were profiled for metabolic stability, plasma protein-binding capacity and pharmacokinetics in vivo. In general, these new BTZs containing N-piperazine, N-piperidine or N-piperidone moiety have excellent antitubercular activity and low cytotoxicity. Several of the compounds showed improved microsomal stability and lower plasma protein-binding, opening a new direction for further lead optimization. And we obtained compound 3o, which maintained good anti-tuberculosis activity (MIC = 8 nM) and presented better in vitro ADME/T and in vivo pharmacokinetic profiles than reported BTZ compound PBTZ169, which may serve as a candidate for the treatment of tuberculosis.
