Inherent Flexibility vis-a-vis Structural Rigidity in Chemically Stable Antimalarial Dispiro N-Sulfonylpiperidine Tetraoxanes

Structurally diverse and chemically stable tetraoxanes were formed by peroxidation of N-sulfonylpiperidones. X-ray analysis revealed that the crystal structures possess central spiro-2,5-disubstituted tetraoxane rings trans fused to 6-membered piperidine and cyclohexylidene substituents in classical chair conformations. The more flexible cycloheptane ring exhibited pseudorotation between chair and twist chair conformation. The two sulfonyl oxygen atoms act as hydrogen-bonding acceptors and participate in hydrogen bonding. Docking calculations showed that the tetraoxanes are aligned parallel to the plane of the porphyrin ring of heme so that the iron can attack the O-O bond to initiate redox-mediated reaction to render nanomolar antimalarial potency to these compounds against P. falciparum 3D7.

Microwave-Assisted Three-Component Domino Synthesis of Polysubstituted 4H-Pyran Derivatives and Their Anticancer Activity

An efficient microwave-assisted one-pot procedure has been proposed for the synthesis of new 4-aryl-6-(methylamino)-5-nitro-2-(1H-pyrrol-2-yl)-4H-pyran-3-carbonitriles by condensation of 3-oxo-3-(1H-pyrrol-2-yl)propanenitrile with (E)-N-methyl-1-(methylsulfanyl)-2-nitroethenamine and substituted benzaldehydes in the presence of a catalytic amount of piperidine using ethanol as a solvent. The transformation occurs via successive Knoevenagel condensation, Michael addition, and intramolecular cyclization. The proposed procedure is advantageous due to its one-pot mode, short reaction time, simple purification by recrystallization, and excellent yields. The product structure was confirmed using various spectroscopic techniques, including IR,H-1 and C-13 NMR, LC/MS, elemental analysis, and single crystal X-ray diffraction study. The synthesized compounds were evaluated for their anticancer activity against 60 different human cancer cell lines in nine cancer panels, and two compounds were found to be potent against different cell lines.

Appliance of the piperidinyl-hydrazidoureido linker to benzenesulfonamide compounds: Synthesis, in vitro and in silico evaluation of potent carbonic anhydrase II, IX and XII inhibitors

Herein we report on a new series of hydrazidoureidobenzensulfonamides investigated as inhibitors of the cytosolic human (h) hCA I and II isoforms, as well as the transmembrane, tumor-associated enzymes hCA IX and XII. The reported derivatives contain a 4-substituted piperidine fragment in which the hydrazidoureido linker has been involved as spacer between the benzenesulfonamide fragment which binds the zinc ion from the active site, and the tail of the inhibitor. Depending on the substitution pattern at the piperidine ring, low nanomolar inhibitors were detected against hCA II, hCA IX and hCA XII, making the new class of sulfonamides of interest for various pharmacologic applications.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 13925-07-0, you can contact me at any time and look forward to more communication. Product Details of 13925-07-0.

Hyperpolarized long-lived nuclear spin states in monodeuterated methyl groups

Monodeuterated methyl groups may support a long-lived nuclear spin state, with a relaxation time exceeding the conventional spin-lattice relaxation time T-1. Dissolution-DNP (dynamic nuclear polarization) may be used to hyperpolarize such a long-lived spin state. This is demonstrated for the CH2D groups of a piperidine derivative. The polarized sample is manipulated in the ambient magnetic field of the laboratory, without destruction of the hyperpolarized singlet order. Strongly enhanced CH2D signals are observed more than one minute after dissolution, even in the presence of paramagnetic radicals, by which time the NMR signal from the hyperpolarized proton magnetization has completely disappeared.

Anodic benzylic C(sp(3))-H amination: unified access to pyrrolidines and piperidines

An electrochemical aliphatic C-H amination strategy was developed to access the important heterocyclic motifs of pyrrolidines and piperidines within a uniform reaction protocol. The mechanism of this unprecedented C-H amination strategy involves anodic C-H activation to generate a benzylic cation, which is efficiently trapped by a nitrogen nucleophile. The applicability of the process is demonstrated for 40 examples comprising both 5- and 6-membered ring formations.

Acetate Kinase (AcK) is Essential for Microbial Growth and Betel-derived Compounds Potentially Target AcK, PhoP and MDR Proteins in M. tuberculosis, V. cholerae and Pathogenic E. coli: An in silico and in vitro Study

Background: Mycobacterium tuberculosis, Vibrio cholerae, and pathogenic Escherichia coli are global concerns for public health. The emergence of multi-drug resistant (MDR) strains of these pathogens is creating additional challenges in controlling infections caused by these deadly bacteria. Recently, we reported that Acetate kinase (AcK) could be a broad-spectrum novel target in several bacteria including these pathogens. Methods: Here, using in silico and in vitro approaches we show that (i) AcK is an essential protein in pathogenic bacteria; (ii) natural compounds Chlorogenic acid and Pinoresinol from Piper betel and Piperidine derivative compound 6-oxopiperidine-3-carboxylic acid inhibit the growth of pathogenic E. coli and M. tuberculosis by targeting AcK with equal or higher efficacy than the currently used antibiotics; (iii) molecular modeling and docking studies show interactions between inhibitors and AcK that correlate with the experimental results; (iv) these compounds are highly effective even on MDR strains of these pathogens; (v) further, the compounds may also target bacterial two-component system proteins that help bacteria in expressing the genes related to drug resistance and virulence; and (vi) finally, all the tested compounds are predicted to have drug-like properties. Results and Conclusion: Suggesting that, these Piper betel derived compounds may be further tested for developing a novel class of broad-spectrum drugs against various common and MDR pathogens.

Kinetics and quantification of the electrophilic reactivities of substituted thiophenes and structure-reactivity relationships

Second-order rate constants (k(1)) have been measured spectrophotometrically for reactions of 2-methoxy-3-X-5-nitrothiophene 1a-c (X = NO2, CN, and COCH3) with secondary cyclic amines (pyrrolidine 2a, piperidine 2b, and morpholine 2c) in CH3CN and 91:9 (v/v) CH3OH/CH3CN at 20 degrees C. The experimental data show that the rate constants (k(1)) values exhibit good correlation with the parameters of nucphilicity (N) of the amines 2a-c and are consistent with the Mayr’s relationship log k (20 degrees C) = s(E + N). We have shown that the electrophilicity parameters E derived for 1a-c and those reported previously for the thiophenes 1d-g (X=SO2CH3, CO2CH3, CONH2, and H) are linearly related to the pK(a) values for their gem-dimethoxy complexes in methanol. Using this correlation, we successfully evaluated the electrophilicity E values of 12 structurally diverse electrophiles in methanol for the first time. In addition, a satisfactory linear correlation (r(2) = 0.9726) between the experimental (log k(exp)) and the calculated (log k(calcd)) values for the sigma-complexation reactions of these 12 electrophiles with methoxide ion in methanol has been observed and discussed.

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 41979-39-9, in my other articles.

Modified Ti-MWW Zeolite as a Highly Efficient Catalyst for the Cyclopentene Epoxidation Reaction

The liquid-phase epoxidation of cyclopentene (CPE) was performed in the Ti-zeolite/H(2)O(2)catalytic system for the clean synthesis of cyclopentene oxide. Among all the Ti-zeolites (Ti-Beta, Ti-MOR, Ti-MCM-68, TS-1, TS-2, and Ti-MWW) investigated in the present study, Ti-MWW provided relatively lower CPE conversion of 13% due to the diffusion constrains but a higher CPO selectivity of 99.5%. The catalytic performance of Ti-MWW was significantly enhanced by piperidine (PI) treatment, with the CPE conversion and CPO selectivity increased to 97.8 and 99.9%, respectively. The structural rearrangement upon PI treatment converted the 3-dimensional (3D) MWW structure to a 2D lamellar one, which enlarged the interlayer space and greatly alleviated the diffusion constrains of cyclic cyclopentene. Furthermore, the newly constructed open site six-coordinated Ti active sites with PI as the ligand exhibited higher catalytic activity. The two factors contributed to more significant enhancement of the activity upon PI-assisted structural arrangement compared to the cases in linear alkenes.

Cyclometalated Ruthenium Catalyst Enables Ortho-Selective C-H Alkylation with Secondary Alkyl Bromides

Although Ru-catalyzed meta-selective sp(2) C-H alkylation with secondary alkyl halides is well established, ortho selectivity has never been achieved. We demonstrate that the use of a cyclometalated Ru-complex, RuBnN, as the catalyst results in a complete switch of the inherent meta-selectivity to ortho selectivity in the Ru-catalyzed sp(2) C-H alkylation reaction with unactivated secondary alkyl halides. The high catalytic activity of RuBnN allows mild reaction conditions that result in a transformation of broad scope and versatility. Preliminary mechanistic studies suggest that a bis-cycloruthenated species is the key intermediate undergoing oxidative addition with the alkyl bromides, thus avoiding the more common SET pathway associated with meta-selectivity.
