Cu(I)-Induced Activation of Furan for Inverse Electron Demand ADAR with Alkenes toward Regioselective Synthesis of Tetrahydropyridine

The aza-Diels-Alder reaction of various alkenes and in situ formed 1-aza-1,3-dienes from the reaction of furan/pyrrole/thiophene and PhINTs for the regioselective synthesis of tetrahydropyridine (THP) derivatives was realized. The reaction was catalyzed by Tp(Me2)Cu as a catalyst under very mild reaction conditions. Structurally different alkenes, along with an alkyne, have been utilized as dienophiles to afford a wide range of different THP derivatives up to 70% yield. The potential application of the envisaged method was also investigated by a gram-scale synthesis.

Rapid naked-eye colorimetric detection of gaseous alkaline analytes using rhodamine B hydrazone-coated silica strips

A novel chemosensor based on rhodamine B hydrazone was developed. The chemical structure of the new rhodamine B hydrazone was verified using different spectroscopic techniques. The surface morphology of the rhodamine B hydrazone was determined by scanning electron microscopy (SEM), which revealed self-assembly in the form of layered aggregations. A thin layer chromatography (TLC) test strip impregnated with rhodamine B hydrazone was fabricated to function as a qualitative optical tool for the rapid detection of alkaline vapors (1 min), including ammonia, triethylamine, piperidine, pyridine, and hydrazine monohydrate. The colorimetric sensing of alkaline vapors was achieved through color changes of the rhodamine B hydrazone-coated silica strips from pink to colorless or faded pink upon exposure to the vapors of the alkaline analytes at 0.1 mu l. The colorimetric changes can be tracked by the naked-eye or by using a smartphone camera. Reversible ring-opening/ring-closure of the spirolactam rings of the probe was confirmed by UV/vis and H-1 NMR analyses. The colorimetric detection of alkaline vapors occurred through deprotonation of the ring-opened amide form of the bis-hydrazone material supported on the TLC silica strip. The proposed detection method offers several advantages, including facile fabrication, simple operation without the need for a special device or skilled operators, easy handling, and real-time sensing of alkaline vapors.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Antifungal Activity of Morpholine and Piperidine Based Surfactants

Microorganisms have the remarkable capacity to develop resistance to antimicrobial agents. This is of particular concern for fungal pathogens which cause devastating invasive infections with limited treatment options. Thus the need for new antifungal agents is undeniable. This work presents the antifungal properties of four surfactant groups, namely two groups of sulfobe-taines and two groups of quaternary ammonium compounds, all morpholine and piperidine derivatives, against drug susceptible or drug resistant Candida albicans and Cryptococcus neoformans. The values of minimum inhibitory and fungicidal concentrations were determined. As follows from the results, the activities of the obtained compounds differed, however the most active agents from each homologous series of compounds, such as P1653, P1654 and C1653, were pointed out.

Synthesis of new antibacterial agents encompassing tosyl, piperidine, propanamide and 1,3,4-oxadiazole functionalities

A series of propanamide compounds 6a-1 was derived by N-substitution reactions, encompassing tosyl, piperidine and 1,3,4-oxadiazole moieties. The intended array of compounds 6a-1 was afforded by a series of five steps reaction scheme. 1-Tosylpiperidin-4-carboxylate (1) was synthesized by the reaction of tosyl chloride (a) with ethyl isonipecotate (b) under mild basic conditions. Compound 1 was subjected to nucleophillic substitution by hydrazine to synthesize 1-tosylpiperidin-4-carbohydrazide (2). The compound, 5-(1-tosylpiperidin-4-yl)-1,3,4-oxadiazole-2-thiol (3) was synthesized by intermolecular cyclization of compound 2 by CS2 under strong basic conditions. The target compounds, 6a-1, were finally synthesized from 3 by reacting with different electrophiles, 5a-1, in an aprotic polar solvent with sodium hydride as an activator. The different propanamoyl electrophiles, 5a-1, were synthesized by the reaction of different aromatic and aliphatic amines, 4a-1, with 3-bromopropionyl chloride under mild basic conditions. The structural elucidation was carried out using modern spectroscopic techniques including IR, H-1-NMR and EI-MS. The antibacterial potential of synthesized compounds was assessed against five bacterial strains. Compounds 6a, 6c, 6d, 6e and 6f were found to be potent antibacterial agents.

Synthesis, radiolabelling, and evaluation of [C-11]PB212 as a radioligand for imaging sigma-1 receptors using PET

The Sigma-1 receptor (Sig-1R) has been described as a pluripotent modulator of distinct physiological functions and its involvement in various central and peripheral pathological disorders has been demonstrated. However, further investigations are required to understand the complex role of the Sig-1R as a molecular chaperon. A specific PET radioligand would provide a powerful tool in Sig-1R related studies. As part of our efforts to develop a Sig-1R PET radioligand that shows antagonistic properties, we investigated the suitability of 1-(4-(6-methoxynaphthalen-1-yl) butyl)-4-methylpiperidine (designated PB212) for imaging Sig-1R. PB212 is a Sig-1R antagonist and exhibits subnanomolar affinity (K-i = 0.030 nM) towards Sig-1R as well as good to excellent selectivity over Sig-2R. The radiolabelling of [C-11]PB212 was accomplished by O-methylation of the phenolic precursor using [C-11]MeI. In vitro autoradiography with [C-11]PB212 on WT and Sig-1R KO mouse brain tissues revealed high non-specific binding, however using rat spleen tissues from CD1 mice and Wistar rats, high specific binding was observed. The spleen is known to have a high expression of Sig-1R. In vivo PET experiments in Wistar rats also showed high accumulation of [C-11]PB212 in the spleen. Injection of Sig-1R binding compounds, haloperidol (1 mg/kg) or fluspidine (1 mg/kg) shortly before [C-11]PB212 administration induced a drastic reduction of radiotracer accumulation, confirming the specificity of [C-11]PB212 towards Sig-1R in the spleen. The results obtained herein indicate that although [C-11]PB212 is not suitable for imaging Sig-1R in the brain, it is a promising candidate for the detection and quantification of Sig-1Rs in the periphery.

Biological activities of 3,4,5-trihydroxypiperidines and their N- and O-derivatives

3,4,5-Trihydroxypiperidines belong to the family of 1,5-dideoxy-1,5-iminosugar natural products and are structural analogues of pentose monosaccharides in the pyranose form. The biological activities of these apparently structurally simple molecules and their N- and O-alkylated and -arylated derivatives are no less remarkable than their C-6 hydroxymethyl counterparts of the hexoses (such as 1-deoxynojirimycin, DNJ). Their biological profiles indicate that the hydroxymethyl branch is crucial to neither potency nor selectivity, with O-alkylation demonstrated to produce exquisite selectivity extending beyond glycosidase inhibition, to immunosuppressant and antibacterial activities.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 34737-89-8, you can contact me at any time and look forward to more communication. Quality Control of 1-Benzyl-3-methylpiperidin-4-one.

Novel multi-target azinesulfonamides of cyclic amine derivatives as potential antipsychotics with pro-social and pro-cognitive effects

Currently used antipsychotics are characterized by muitireceptor mode of action. While antagonism of dopamine D-2 receptors is responsible for the alleviation of positive symptoms of schizophrenia and the effects at other, particularly serotonergic receptors are necessary for their additional therapeutic effects, there is no consensus regarding an ideal target engagement. Here, a detailed SAR analysis in a series of 45 novel azinesulfonamides of cyclic amine derivatives, involving the aryl-piperazine/piperidine pharmacophore, central alicyclic amine and azinesulfonamide groups has led to the selection of (S)-4-(2-(2(4-(benzo[b]thiophen-4-yl)piperazin-1-yl)ethyl)pyrrolidin-1-yl)sulfonyl)isoquinoline (62). The poly pharmacology profile of 62, characterized by partial 5-HT1AR agonism, 5-HT2A/5-HT7/D-2/D3R antagonism, and blockade of SERT, reduced the positive-like, and negative-like symptoms of psychoses. Compound 62 produced no catalepsy, demonstrated a low hyperprolactinemia liability and displayed pro cognitive effects in the novel object recognition task and attentional set-shifting test. While association of in vitro features with the promising in vivo profile of 62 is still not fully established, its clinical efficacy should be verified in further stages of development.

Can Heteroarenes/Arenes Be Hydrogenated Over Catalytic Pd/C Under Ambient Conditions?

Hydrogenation of over a dozen aromatic compounds, including both heteroarenes and arenes, over palladium on carbon (Pd/C, 1-100 mol%) with H-2-balloon pressure at room temperature is reported. Analyses using pyridine as a model substrate revealed that acetic acid was the best solvent, as using only 1 mol% Pd/C provided piperidine quantitatively. Substrate scope analysis and density functional theory calculations indicated that reaction rates are highly dependent on frontier molecular orbital characteristics and the steric bulkiness of substituents. Moreover, the established method was used for the concise synthesis of the anti-Alzheimer drug donepezil (Aricept (R)).

Unraveling Direct Formation of Hierarchical Zeolite Beta by Dynamic Light Scattering, Small Angle X-ray Scattering, and Liquid and Solid State NMR: Insights at the Supramolecular Level

A case study on the understanding of the formation of hierarchical Beta zeolites using gemini-type piperidine based multiammonium surfactant (N-6-diphe) is reported. Complementary techniques were used to investigate N-6-diphe’s structure-directing effect at the molecular level. Combining characterization of the resulting zeolite materials with the toolboxes herein developed for studying clear solutions and dense gels discloses self-assembly processes that govern the growth (and growth inhibition) of nano-Beta zeolite crystals. In clear solution, small-angle X-ray scattering and liquid-state NMR provide insights about the formation of nanoparticles and their degree of order. N-14 and H-1-DOSY NMR probe the dynamics and mobility of soluble species. In a dense gel, on the other side, Al-27- and Si-29-(MAS) NMR elucidate the varying local connectivity between initial nano-objects and the final solid products. It has been found that cylindrical micelles control the transformation of solubilized silica and alumina during the formation of zeolite nuclei and guide their crystal growth to nano-Beta rods with bimodal mesoporosity. The predominant smaller mesopores (6 to 8 nm) originate from the template’s hydrophobic alkyl chains, while larger mesopores (10 to 30 nm) are supposed to result from a spinodal decomposition-type segregation of phases consisting of as-formed hydrophobic zeolite rods and an aqueous solution.
