Recent applications of aziridine ring expansion reactions in heterocyclic synthesis

The inherent reactivity of the aziridine ring due to ring-strain makes it valuable building blocks for the synthesis of other heterocyclic motifs of biological relevance. Of particular significance is the generation of azomethine ylides from them and cycloaddition of ylides with alkenes, alkynes, and heterocumulenes. The ring undergoes opening followed by cyclization with a variety of reagents either in the presence of a catalyst or without any catalyst. This review article discusses the recent applications of aziridines in syntheses of four- to seven-membered heterocycles of biological relevance such as azetidines, 2-azetidinones, pyrroles, imidazoles, oxazoles, thiazoles, piperidines, pyrazines, pyrimidines, benzoxazines, morpholines, azepanes, benzodiazepines, benzoxazepines, and benzothiazepines.

Synthesis, Cytotoxicity Evaluation, and Computational Insights of Novel 1,4-Diazepane-Based Sigma Ligands

Among several potential applications, sigma receptor ligands can be used as antipsychotics, antiamnesics, and against other neurodegenerative disorders as well as neuroprotective agents. We present herein a new series of diazepane-containing derivatives as sigma R ligands obtained by a conformational expansion approach of our previously synthesized piperidine-based compounds. The best results were reached by benzofurane 2c, 3c and quinoline 2d, 3d-substituted diazepane derivatives, which showed the highest sigma R affinity. The cytotoxic activities of synthesized compounds were evaluated against two cancer cell lines, and the results indicated that none of the compounds induced significant toxicity in these cells. We also evaluated the antioxidant activity by radical scavenging capacity of our best compounds on ABTS and H2O2. The results obtained reveal that our new derivatives possess an excellent antioxidant profile and could be protective for the cells. Overall, the benzofurane derivative 2c due to its strong interaction with the active site of the receptor, as confirmed by molecular dynamic simulations, emerged as the optimum compound with high sigma 1R affinity, low cytotoxicity, and a potent antioxidant activity.

3-Hydroxy-piperidinyl-N-benzyl-acyl-arylhydrazone derivatives reduce neuropathic pain and increase thermal threshold mediated by opioid system

Here in, we report the preparation and evaluation of four 3-hydroxy-piperidine-N-benzyl-aryl-acylhydrazone derivatives (6a-d) for their potential antinociceptive activity. In the tail flick test, compounds 6a and 6d exhibited a significant increase in the latency time of the animals, in comparison to the control group. These two compounds also showed a significant increase in the nociceptive threshold from 1 to 6 h after treatment in the CCI neuropathic pain model. In both cases, the antinociceptive activity was blocked by naloxone, suggesting an opioid mechanism of action, but without sedative or motor coordination effects.

Synthesis and SARs of novel lincomycin derivatives Part 5: optimization of lincomycin analogs exhibiting potent antibacterial activities by chemical modification at the 6-and 7-positions

In order to modify lincomycin at the C-6 and C-7 positions, we prepared target molecules, which have substituted pipecolinic acid at the 6-amino group and a para-substituted phenylthio group at the C-7 position, in application of palladium-catalyzed cross-coupling as a key reaction. As the result of structure-activity relationship (SAR) studies at the 6-position, analogs possessing 4′-cis-(cyclopropylmethyl) piperidine showed significantly strong antibacterial activities against Streptococcus pneumoniae and Streptococcus pyogenes with an erm gene. On the basis of SAR, we further synthesized novel analogs possessing 4′-cis-(cyclopropylmethyl) piperidine by transformation of a C-7 substituent. Consequently, novel derivatives possessing a paraheteroaromatic-phenylthio group at the C-7 position exhibited significantly strong activities against S. pneumoniae and S. pyogenes with an erm gene even when compared with those of telithromycin. Finally, in vivo efficacy of selected two derivatives was evaluated in a rat pulmonary infection model with resistant S. pneumoniae with erm + mef genes. One of them exhibited strong and constant in vivo efficacy in this model, and both compounds showed strong in vivo efficacy against resistant S. pneumoniae with a mef gene.

Metabolomics analysis of nitrogen-containing metabolites between two Dendrobium plants

Nitrogen-containing compounds especially alkaloids are important medicinal ingredients in caulis dendrobii plants. Using solid-phase extraction coupled with liquid chromatography tandem mass spectrometry and multivariate data analysis methods, metabolic profiling of the nitrogen-containing compounds was established to distinguish Dendrobium huoshanense and Dendrobium officinale. Hundreds of nitrogen-containing compounds from the two caulis dendrobii were purified by the MCX cartridges. Some compounds were identified by high-resolution tandem mass spectrometry technology. Together with multivariate data analysis methods, comparative analysis of the metabolic profiling from two caulis dendrobii was conducted. A total of 133 nitrogen-containing compounds were identified, including amino acids, pyrrolidines, tropanes, pyrimidines, purines, indoles, piperidines, guanidines, quinolines, isoquinolines and terpenoids. Metabolic profiling analysis showed that the composition and contents of these chemical components were significantly different between D. huoshanense and D. officinale. Moreover, some components were species-specific, distributed in the two caulis dendrobii, such as pilosine, ternatusine, etc. Because alkaloids are mainly derived from amino acids via multistep biochemical reactions, the correlation analysis suggested that amino acids were partially associated with several types of components and significantly correlated with certain alkaloids. Arginine was extremely correlated with guanidines. Pyrimidines, purines and niacin-nicotinamide metabolic intermediates were associated with three independent networks. The results further enriched the chemical components currently identified from caulis dendrobii and provided a technical reference for detecting nitrogen-containing compounds in other medicinal plants.

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 201341-05-1 is helpful to your research. Category: piperidines.

Regio- and Stereoselective Palladium-Catalyzed C(sp(3))-H Arylation of Pyrrolidines and Piperidines with C(3) Directing Groups

The selective synthesis of cis-3,4-disubstituted pyrrolidines and piperidines is achieved by a Pd-catalyzed C-H arylation with excellent regio- and stereoselectivity using an aminoquinoline auxiliary at C(3). The arylation conditions are silver free, use a low catalyst loading, and employ inexpensive K2CO3 as a base. Directing group removal is accomplished under new, mild conditions to access amide-, acid-, ester-, and alcohol-containing fragments and building blocks. This C-H arylation protocol enabled a short and stereocontrolled formal synthesis of (-)-paroxetine.

Discovery of Aryl Formyl Piperidine Derivatives as Potent, Reversible, and Selective Monoacylglycerol Lipase Inhibitors

Most of the current monoacylglycerol lipase (MAGL) inhibitors function by an irreversible mechanism of action, causing a series of side effects. Herein, starting from irreversible inhibitors, 25 compounds were synthesized and evaluated in vitro for MAGL inhibition, among which, compound 36 showed the most potent inhibitory activity (IC50 = 15 nM). Crucially, docking studies demonstrated that the m-chlorine-substituted aniline fragment occupied a hydrophobic subpocket enclosed by side chains of Val191, Tyr194, Val270, and Lys273, which creatively identify a new key anchoring point for the development of new MAGL inhibitors. Furthermore, in vivo evaluation innovatively revealed that this reversible inhibitor 36 significantly ameliorated depressive-like behaviors induced by reserpine. To the best of our knowledge, this is the first time that reversible inhibitors of MAGL were developed to support MAGL as a potential therapeutic target for depression.

Deconstructive fluorination of cyclic amines by carbon-carbon cleavage

Deconstructive functionalizations involving scission of carbon-carbon double bonds are well established. In contrast, unstrained C(sp(3))-C(sp(3)) bond cleavage and functionalization have less precedent. Here we report the use of deconstructive fluorination to access mono-and difluorinated amine derivatives by C(sp(3))-C(sp(3)) bond cleavage in saturated nitrogen heterocycles such as piperidines and pyrrolidines. Silver-mediated ring-opening fluorination using Selectfluor highlights a strategy for cyclic amine functionalization and late-stage skeletal diversification, establishing cyclic amines as synthons for amino alkyl radicals and providing synthetic routes to valuable building blocks.
