Anal. and semipreparative high-performance liquid chromatog. (HPLC) enantioseparation of the proton-pump inhibitor omeprazole (OME) and its potential organic chiral impurities were accomplished on the immobilized-type Chiralpak IA chiral stationary phase (CSP) under both polar organic and normal-phase conditions. The (S)-enantiomers were isolated with a purity of >99% ee and their absolute configuration was empirically assigned by CD spectroscopy. A chemo- and enantioselective HPLC method was validated to control the enantiomeric purity of the (S)-enantiomer of OME (ESO), an active ingredient contained in drug products, in the presence of chiral and achiral related substances. The precision, linearity and accuracy of the determination of the (R)-impurity as well as the recovery of ESO from a pharmaceutical preparation were determined The proposed method uses the mixture Me tert-butylether (MtBE)-Et acetate (EA)-EtOH (EtOH)-diethylamine (DEA) 60:40:5:0.1 (volume/volume/volume/volume) as a mobile phase. In these conditions, linearity over the concentration range 0.5-25 μg/mL for (R)-enantiomer was obtained. The limits of detection and quantification were 99 and 333 ng/mL, resp. The intra and inter-day assay precision was <2% (RSD%). There is still a lot of research devoted to this compound(SMILES：CC1=CN=C(CSC2=NC3=CC(OC)=CC=C3N2)C(C)=C1OC)Safety of 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, and with the development of science, more effects of this compound(73590-85-9) can be discovered.

Synthetic Route of C10H14N2O. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about Biotransformation of LASSBio-579 and pharmacological evaluation of p-hydroxylated metabolite a N-phenylpiperazine antipsychotic lead compound. Author is Gomes, Tatiana F.; Pompeu, Thais E. T.; Rodrigues, Daniel A.; Noel, Francois; Menegatti, Ricardo; Andrade, Carolina H.; Sabino, Jose R.; Gil, Eric S.; Dalla Costa, Teresa; Betti, Andresa H.; Antonio, Camila B.; Rates, Stela M. K.; Fraga, Carlos A. M.; Barreiro, Eliezer J.; de Oliveira, Valeria.

Using a combination of docking and mol. dynamics simulations, we predicted that p-hydroxylation by CYP1A2 would be the main metabolic pathway for the 1-[1-(4-chlorophenyl)-1H-4pyrazolylmethyl] phenylhexahydropiperazine, LASSBio-579. As the result of a screening process with strains of filamentous fungi, Cunninghamella echinulata ATCC 9244 was chosen to scale up the preparation of the p-hydroxylated metabolite. About 30 min after i.p. administration of LASSBio-579 to rats was identified as the p-hydroxylated metabolite, confirming our in silico previsions. Chem. synthesis of the metabolite was performed and allowed its pharmacol. evaluation in binding assays revealing its high affinity for D2 and D4 receptors, indicating that this metabolite should participate to the antipsychotic effect of LASSBio-579 in vivo. Furthermore, we report here that both LASSBio-579 and its p-hydroxylated metabolite have a much lower affinity than clozapine for two receptors involved in adverse reactions. Voltammetric assays were useful to understand the redox profile of LASSBio-579.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Russian Journal of Organic Chemistry called N-Substituted S-Alkyl Carbamothioates in the Synthesis of Nitrogen-containing Functional Derivatives of the Adamantane Series, Author is Klimochkin, Yu. N.; Ivleva, E. A., which mentions a compound: 56621-48-8, SMILESS is OC1=CC=C(N2CCNCC2)C=C1, Molecular C10H14N2O, Formula: C10H14N2O.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about Molecular Mechanism for Isoform-Selective Inhibition of Acyl Protein Thioesterases 1 and 2 (APT1 and APT2).Name: 4-(Piperazin-1-yl)phenol.

Post-translational S-palmitoylation directs the trafficking and membrane localization of hundreds of cellular proteins, often involving a coordinated palmitoylation cycle that requires both protein acyltransferases (PATs) and acylprotein thioesterases (APTs) to actively redistribute S-palmitoylated proteins toward different cellular membrane compartments. This process is necessary for the trafficking and oncogenic signaling of S-palmitoylated Ras isoforms, and potentially other peripheral membrane proteins. Depalmitoylating enzymes APT1 and APT2 are sep. conserved in all vertebrates, suggesting unique functional roles for each enzyme. The recent discovery of APT isoform-selective inhibitors ML348 and ML349 has opened new possibilities to probe the function of each enzyme, yet it remains unclear how each inhibitor achieves orthogonal inhibition. Here, the authors report the high-resolution structure of human APT2 in complex with ML349 (1.64 Å), as well as the complementary structure of human APT1 bound to ML348 (1.55 Å). Although the overall peptide backbone structures are nearly identical, each inhibitor adopted a distinct conformation within each active site. In APT1, ML348 was positioned above the catalytic triad, but in APT2, the sulfonyl group of ML349 formed H-bonds with active site resident water mols. to indirectly engage the catalytic triad and oxyanion hole. Reciprocal mutagenesis and activity profiling revealed several differing residues surrounding the active site that served as critical gatekeepers for isoform accessibility and dynamics. Structural and biochem. anal. suggested that the inhibitors occupy a putative acyl-binding region, establishing the mechanism for isoform-specific inhibition, hydrolysis of acyl substrates, and structural orthogonality important for future probe development.

Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about Acaricidal properties of piperazine and its derivatives against house-dust and stored-food mites.COA of Formula: C10H14N2O.

Piperazine derivatives possess pharmacol. properties, yet the acaricidal activity of these compounds has not been investigated. This study was conducted to evaluate the color alteration and acaricidal activity of piperazine derivatives against Dermatophagoides spp. and Tyrophagus putrescentiae using filter paper and fumigant methods. In a fumigant bioassay, 1-phenylpiperazine (7.83 μg/cm2) against D. farinae was found to be 4.7-fold more toxic than DEET (36.84 μg/cm2), followed by benzyl benzoate (9.72 μg/cm2), piperazine (11.41 μg/cm2), 1-ethoxycarbonylpiperazine (20.14 μg/cm2), and 1-(2-methoxyphenyl)piperazine (22.14 μg/cm2). In a filter paper bioassay, 1-(2-methoxyphenyl)piperazine (3.65 μg/cm2) was 5.7-fold more toxic than DEET (20.64 μg/cm2), followed by 1-ethoxycarbonylpiperazine (4.02 μg/cm2), 1-phenylpiperazine (4.75 μg/cm2), benzyl benzoate (7.83 μg/cm2), and piperazine (10.59 μg/cm2). Similar results have been exhibited with piperazine derivatives against D. pteronyssinus. However, no activity against T. putrescentiae was observed for piperazine derivatives, except for piperazine. These results indicate that piperazine derivatives may be suitable as vapor-phase acaricide fumigants owing to their high volatility, acaricidal activity and safety. 1-Phenylpiperazine was found to be an excellent mite indicator based on the color change it induced. Taken together, these findings indicate that piperazine derivatives may be used to replace existing problematical acaricides owing to their activity and ability to act as a mite indicator.

The well-known diuretic Ethacrynic acid (EA, Edecrin), showing low anti-proliferative activities, was chem. modified at different positions. The new EA derivatives have been tested in vitro in anti-proliferative assays on both tumor KB (epidermal carcinoma) and leukemia HL60 (promyelocytic) cells suitable targets for anticancer activity. Reduction of the α-β double bond of EA completely abolished anti-cancer activities, whereas introduction of either 2-(4-substituted phenyl)ethanamine (series A) or 4-(4-substituted phenyl)piperazine (series B) moieties generated compounds showing moderate to strong anti-proliferative activities against human cancer cell lines. Several substitutions on the Ph of these two moieties are tolerated. The mechanism of action of the EA derivatives prepared in this study is more complex than the inhibition of glutathione S-transferase π ascribed as unique effect to EA and might help to overcome tumor resistances.
