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.

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.

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.

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.

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.

Azetidiniums: Ring-Expansion to Pyrrolidines, Piperidines, Azepanes, and Azocanes

The 4-membered ring in bicyclic azetidiniums, e.g. 1-azabicyclo[2.n.0]alkanes (n= 1-4), can be efficiently transformed to larger rings. This minireview focuses on the ring-expansion of these azetidiniums to five- and eight-membered nitrogen containing heterocycles (pyrrolidines, piperidines, azepanes and azocanes). The ring-expansion is induced by nucleophiles which can be internal nucleophiles (leaving groups), or external nucleophiles.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 3056-33-5. Recommanded Product: N2,9-Diacetylguanine.

Synthesis of Piperidines via Intramolecular Hydride Transfer from alpha-Amino sp(3) Carbon Atoms to Ethenetricarboxylate-Derived Fragments and Further Cyclization

The cyclization of amides derived from ethenetricarboxylic acid bearing tert-amino groups has been examined. The amides were efficiently converted to piperidine derivatives (2-piperidones) upon heating in a polar solvent (e.g., DMSO or DMF) via intramolecular hydride transfer and subsequent ring closure. The reaction was less efficient in the presence of a Lewis acid. The reactivity varies depending on the alkyl substituents of tert-amino groups, probably due to steric effects. The hydride transfer/cyclization mechanism was investigated by DFT calculations. The reaction of the carboxylic acid and relatively bulky diamines such as diisopropyl-substituted diamine in the presence of amide condensation reagents at 60 degrees C gave the piperidine derivatives in a one-pot reaction. The reaction of the diisopropylamine substituted piperidine product with primary amines gave secondary amine-substituted piperidines.

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 108-26-9, in my other articles.

Adsorption characteristics of aromatic pollutants and their halogenated derivatives on bio-based poly (ether-pyridine)s

In this work, innovative poly(ether pyridine) polymers obtained from bio-based monomers and pentafluoropyridine derivatives were elaborated in order to adsorb aromatic pollutants and their halogenated derivatives. These polymers were obtained with satisfactory yields by polycondensation of four pyridinium monomers (respectively based on morpholine, piperazine, dimethylamine and phenol) with isosorbide or bisphenol A. The adsorption efficiency data demonstrate that the poly(etherpyridine) based on isosorbide and morpholine-based monomer (P2) is the more efficient sorbent toward aromatic pollutants and their derivatives. Four aromatic pollutants, p-hydroxybenzoic acid, toluic acid, deisopropylatrazine, and 2,4,6-trichlorophenol, were chosen as the adsorbate to investigate the adsorption efficiency, kinetics and isotherms of the poly(ether pyridine) P2. The results demonstrate that the pseudo-second order was the best to describe the adsorption of the four target pollutants by the efficient sorbent P2 with good correlation. The experimental data of the four target pollutants adsorption were analyzed by Langmuir and Freundlich isotherms. Polymer P2 shows very high affinity (low 1/n value) for p-hydroxybenzoic acid and for 2,4,6-trichlorophenol, compared to other adsorbents. Three consecutive adsorption/desorption cycles toward eight aromatic pollutants were obtained for the efficient sorbent P2.

Synthesis and radical copolymerization of novel propyl cyanoacrylate monomers

Novel phenyl-trisubstituted propyl 3-(R-phenyl)-2-cyanoacrylates (where R is 2,4,5-trimethyl, 2,4,6-trimethyl, 2,3-dimethyl-4-methoxy, 2,5-dimethyl-4-methoxy, 2,4-dimethoxy-3-methyl, 2,4-dimethoxy-6-methyl, 4-hydoxy-3,5-dimethyl, 2,3,4-trimethoxy, 2,4,5-trimethoxy, 2,4,6-trimethoxy, 3,4,5-trimethoxy) were prepared using piperidine-catalyzed condensation of substituted benzoic aldehydes and propyl ester of cyanoacetic acid with good yields (72-97 wt%). The ethenylbenzene copolymerization of cyanoacrylates (at 3/1 mol feed ratio) in solution with radical initiation at 70 degrees C resulted in formation of copolymers having M-W 3.9 to 27.8 kD and 8.4-25.8 mol% of cyanoacrylate. FTIR, H-1 and C-13 NMR were used to analyze the structure. Thermal behavior of the copolymers was analyzed by DSC, T-g (81-129 degrees C) and TGA. Decomposition of the copolymers in nitrogen occurred in two steps, first in the 200-500 degrees C range with residue (0.5-7.3 wt%)and then in the 500-800 degrees C range.
