2D & 3D-QSAR Study on Novel Piperidine and Piperazine Derivatives as Acetylcholinesterase Enzyme Inhibitors

Introduction: Acetylcholinesterase enzyme (AChE) is the main target in Alzheimer’s disease therapy and designing of novel AChE inhibitors is a great deal of attention. Methods: In this study, 2D-QSAR and 3D-QSAR models were generated using stepwise multiple linear regressions (SW-MLR) and comparative molecular field analysis (CoMFA) respectively. Results: It was found that CoMFA model with r(2) of 0.947 for the training set and r(2) of 0.816 for the test set is more favorable than model which is established by SW-MLR method with r(2) = 0.825 and r2pred = 0.778 in 2D-QSAR. Conclusion: In addition, obtaining models were validated by cross validation with cut off values of q(2) > 0.5 and r(2) pred > 0.6.

Sustainable Synthesis of a Potent and Selective 5-HT7 Receptor Antagonist Using a Mechanochemical Approach

A mechanochemical procedure was developed to obtain PZ-1361, a potent and selective 5-HT7 receptor antagonist, with antidepressant properties in rodents. The elaborated protocol offered several advantages over classical batch synthesis, including improvement of the overall yield (from 34% to 64%), reduction of reaction time (from 60 to 5.5 h), limitation of the use of toxic solvents, and the formation of byproducts. This approach represents a rare example of the synthesis of biologically active compounds exclusively performed using mechanochemical reactions.

Aiming to Miss a Moving Target: Bromo and Extra Terminal Domain (BET) Selectivity in Constrained ATAD2 Inhibitors

ATAD2 is a cancer-associated protein whose bromodomain has been described as among the least druggable of its class. In our recent disclosure of the first chemical probe against this bromodomain, GSK8814 (6), we described the use of a conformationally constrained methoxy piperidine to gain selectivity over the BET bromodomains. Here we describe an orthogonal conformational restriction strategy of the piperidine ring to give potent and selective tropane inhibitors and show structural insights into why this was more challenging than expected. Greater understanding of why different rational approaches succeeded or failed should help in the future design of selectivity in the bromodomain family.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 14047-28-0, you can contact me at any time and look forward to more communication. SDS of cas: 14047-28-0.

CO2 capture using aqueous 1-(2-Hydroxyethyl) piperidine and its blends with piperazine: Solubility and enthalpy

In this article, equilibrium CO2 solubility in aqueous 1-(2-Hydroxyethyl) piperidine (HEP) solutions pertaining concentrations (1, 2, 3) mol/L in the temperature range (303.15-323.15) K, and CO2 partial pressure range 0.1-100 kPa are presented. HEP; being a tertiary alkanolamine, its rate of CO2 absorption is comparatively slower than primary or secondary alkanolamine. Piperazine (PZ), a rate promoter was added to HEP in 1:4 mol ratio to form blends having enhance rate of CO2 absorption. Equilibrium CO2 solubility in four different aqueous blends; (0.8 mol/L HEP + 0.2 mol/L. PZ), (1.6 mol/L HEP + 0.4 mol/L PZ), (2.4 mol/L HEP + 0.6 mol/L PZ), (3.2 mol/L HEP + 0.8 mol/L PZ) were measured over the temperature range of (303.15-323.15) K and CO2 partial pressure spanning over 0-70 kPa. Equilibrium constant for deprotonation reaction of HEP was estimated by measuring pKa of aqueous HEP solution at 298.15, 303.15, 313.15, 323.15 and 333.15 K. Experimentally obtained CO2 solubility data for single and blended amine solutions were correlated efficiently using activity coefficient model with AAD % of 3.76 and 3.22, respectively. Speciation of both single and blended amine solutions in their equilibrated liquid phase were predicted. Interaction parameters obtained through thermodynamic modelling of equilibrium solubility data for single and blended amine solutions were used to predict the enthalpy of CO2 absorption.

Synthesis, Antioxidant, and Antileishmanial Activities of New Bis-N-amino Triazole Derivatives

Synthesis of new bis-N-imino triazole derivatives containing oxadiazole 2, its Mannich base 3, and the S-alkyl group 4 is presented. Bis-N-iminotriazole 2 is formed in the reaction of compound 1 with terephthalaldehyde. Bis N-iminotriazole derivatives containing Mannich base 3 are synthesized by the reaction of morpholine or piperidine with the compound 2. The compound 2 also reacts with alkyl halides (butyl, pentyl, hexyl, heptyl) to give S-alkylated bis-N-imino triazoles 4. Structures of the new compounds are characterized by IR, H-1, and C-13 NMR, and mass spectral data. Antioxidant (FRAP and DPPH assay) and antileishmanial activities tests of the compounds indicate that the products 2, 3a, and 3b demonstrate moderate antioxidant activity in both DPPH and FRAP assays. The antileishmanial tests indicate high activity of the compounds 3a and 3b.

In silico investigation of quorum quenching potential of Piper nigrum, Piper betle and Coscinium fenestratum on Vibrio cholerae

Current study investigates the ability of phytoligands to inhibit biofilm formation in multidrug resistant, clinically isolated V. cholerae. Methanolic extracts of Coscinium fenestratum, Piper betle and Piper nigrum were checked for their antibiofilm activity. The herbal bioactive compounds were screened by LC/MS-MS and binding potentials against the drug targets were predicted by molecular docking. The extracts exhibited a MIC in a range of 0.1mg/mL- 0.15mg/mL. Reduction of EPS and rhamnolipids was found to be 84.27%, 67% and 46.6% respectively by C. fenestratum, P. betle and P. nigrum. Six major proteins were selected as putative targets. Of the 6 targets, the phytoligands were effective against AphB, HapR, LuxO and Vps. Berberine present in C. fenestratum (binding energy of -8.6 kcal/mol), Eugenol in P. betle (binding energy – 6.2 kcal/mol) and Piperidine in P. nigrum (binding energy -4.0 kcal/mol) demonstrated effective minimum binding energy against AphB. In silico analysis has revealed that the QS proteins of V. cholerae targeted by the phytoligands might destabilize the biofilm on density dependent manner based on inhibition of surface adhesion and attenuating the virulence factors leading to quorum sensing inhibition. Berberine and Eugenol can be used as quorum inhibitors for attenuation of MDR V. cholerae at sub inhibitory concentration of 50 mu g/mL.

Palladium nanoparticles on a pyridinium supported ionic liquid phase: a recyclable and low-leaching palladium catalyst for aminocarbonylation reactions

A new SILP (Supported Ionic Liquid Phase) palladium catalyst was prepared and characterized by(13)C and(29)Si CP MAS NMR, DTG, FTIR and TEM. The presence of the grafted pyridinium cations on the surface of the support was found to result in the formation of highly dispersed Pd nanoparticles with their diameter in the range of 1-2 nm. The catalyst was proved to be active not only in the aminocarbonylation of some model compounds but also in the synthesis of active pharmaceutical ingredients. Catalyst recycling and palladium leaching studies were carried out for the first time in aminocarbonylations leading to CX-546(1-(1,4-benzodioxan-6-ylcarbonyl)piperidine), Moclobemide, Nikethamide and a precursor of Finasteride. The latter reaction proves that not only aryl iodides but also an iodoalkene can be converted into the products with the help of the heterogeneous catalyst. The results show that the conditions should be always fine-tuned in the reactions of different substrates to achieve optimal results. Palladium loss was also observed to depend considerably on the nature of the reaction partners.

Neurotoxicity of Prosopis juliflora: from Natural Poisoning to Mechanism of Action of Its Piperidine Alkaloids

Prosopis juliflora was introduced in northeastern Brazil in the 1940s, and since then, it has been available as an alternative for animal nutrition. However, the consumption of P. juliflora as main or sole source of food causes an illness in animals known locally as cara torta disease. Cattle and goats experimentally intoxicated presents neurotoxic damage in the central nervous system. Histologic lesions were mainly characterized by vacuolation and loss of neurons in trigeminal motor nuclei. Furthermore, mitochondrial damage in neurons and gliosis was reported in trigeminal nuclei of intoxicated cattle. Studies, using neural cell cultures, have reproduced the main cellular alterations visualized in cara torta disease and contributed to understanding the mechanism of action piperidine alkaloids, the main neurotoxic compound in P. juliflora leaves and pods. Here, we will present aspects of the biological and toxicological properties of P. juliflora and its pharmacologically active compounds.
