Author is Andonova, Lily; Valkova, Iva; Zheleva-Dimitrova, Dimitrina; Georgieva, Maya; Momekov, Georgi; Zlatkov, Alexander.

A series of new xanthine derivatives comprising an arylpiperazine I (R = Bn, 4-FC6H4, 2-MeOC6H4, etc.) moiety at N1 were synthesized. The cytotoxicity against human T-cell leukemia cell SKW-3, human acute myeloid leukemia HL-60 and human Bcell precursor leukemia cell REH is evaluated. The relationship between the structure and cytotoxicity of the compounds was investigated by quant. structure-activity relationship (QSAR) anal. and the important structural parameters were drawn. The purity of the substances is proven by corresponding m.ps. and elemental anal. The antioxidant activity has been evaluated by four common methods – DPPH, ABTS, FRAP and lipid peroxidation assay. The cytotoxic effects of the tested series were evaluated using the standard MTT-dye reduction assay on three tumor cell lines. The highest antioxidant activity was demonstrated by compound I (R = 4-HOC6H4). The highest cytotoxic effect was observed for compound I (R = bis(4-fluorophenyl)methyl). It was found that cytotoxicity against SKW-3 depends on the electron d. distribution in the structures. Branching of the mol. skeleton and introduction of heteroatoms like fluorine and sulfur in the structures also significantly improved the antiproliferative activity of the compounds

Compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, is researched, Molecular C17H19N3O2S, CAS is 73590-85-9, about Omeprazole determination using HPLC with coulometric detection.

A sensitive high performance liquid chromatog. (HPLC) method for the determination of omeprazole and three related benzimidazoles is reported. Coulometric detection was carried out at +800 mV using a porous carbon electrode. The linear range is 0.01-10 μg/mL. The method has a high degree of precision; the relative standard deviation of omeprazole at a concentration of 1.06 μg/mL was 0.7% (n=4). The cyclic voltammogram of omeprazole is consistent with the hydrodynamic voltammogram exhibiting a single major irreversible oxidative wave with a peak potential at +1105 mV. The response factors for the four compounds are similar indicating that the oxidative process does not involve the sulfur moiety exclusively. The data are most consistent with oxidation primarily of the benzimidazole groups. The method was applied successfully to the determination of omeprazole in a paste formulation.

Computed Properties of C10H14N2O. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 4-(Piperazin-1-yl)phenol, is researched, Molecular C10H14N2O, CAS is 56621-48-8, about Toxicological detection of the new designer drug 1-(4-methoxyphenyl)piperazine and its metabolites in urine and differentiation from an intake of structurally related medicaments using gas chromatography-mass spectrometry. Author is Staack, Roland F.; Maurer, Hans H..

Studies are described on the toxicol. anal. of the piperazine-derived designer drug 1-(4-methoxyphenyl)piperazine (MeOPP) in rat urine using gas chromatog.-mass spectrometry (GC-MS). The authors’ systematic toxicol. anal. (STA) procedure using full-scan GC-MS after acid hydrolysis, liquid-liquid extraction and microwave-assisted acetylation allowed the detection of MeOPP and its metabolites 1-(4-hydroxy phenyl)piperazine and 4-hydroxyaniline in rat urine after administration of a single dose corresponding to doses commonly taken by drug users. Therefore, this procedure should also be suitable for detection of a MeOPP intake in human urine. However, the metabolites of MeOPP are not unique and can be produced from other drugs. Therefore, differentiation of use of this designer drug from use of the medicaments dropropizine, oxypertine or others, which are metabolized to the MeOPP isomer 1-(2-methoxyphenyl)piperazine, is discussed.

Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms.

Author is Staack, Roland F.; Theobald, Denis S.; Maurer, Hans H..

Studies are described on the metabolism and the toxicol. anal. of the nonopioid cough suppressant dropropizine [R,S-3-(4-phenyl-1-piperazinyl)1,2-propandiol, DRO] in human urine using gas chromatog.-mass spectrometry (GC-MS). The metabolism studies showed that DRO was metabolized in humans mainly by hydroxylation of the aromatic ring, by N-dealkylation of the parent drug and of the hydroxyl-metabolite to the corresponding N-phenylpiperazines, and by degradation of the piperazine moiety. The authors’ systematic toxicol. anal. (STA) procedure using full-scan GC-MS after acid hydrolysis, liquid-liquid extraction, and microwave-assisted acetylation allowed the unambiguous detection of DRO and its above-mentioned metabolites in human urine up to about 32 h after intake of a single common therapeutic dose. The target analytes were found to be the parent compound DRO (earlier phase of excretion) and the hydroxylated metabolite para-hydroxy-DRO (later phase of excretion). Both allowed unambiguous detection of an intake of DRO and also differentiation from other phenylpiperazine derivatives

A series of novel acetamine Ph pleuromutilin derivatives incorporating 2-aminothiophenol moieties into the C14 side chain were synthesized via acylation reactions under mild conditions. The in vitro antibacterial activities of the synthesized derivatives against three Staphylococcus aureus (MRSA ATCC 43300, ATCC 29213 and AD 3) and two Escherichia coli (ATCC 25922 and 9-1) were evaluated by the broth dilution method. Most of the synthesized derivatives displayed potent activities. Compound I was found to be the most active antibacterial derivative against MRSA (minimal inhibitory concentration = 0.015 μg/mL) which may lead to a promising antibacterial drug. Furthermore, compound I displayed more rapid bactericidal kinetic than tiamulin in in vitro time-kill studies and possessed a longer PAE than tiamulin against MRSA. The PK properties of compound I were then measured. The half life (t1/2), clearance rate (Cl) and the area under the plasma concentration-time curve (AUC0→∞) of compound I were 6.88 h, 21.64 L/h/kg and 0.48 μg h/mL, resp. The in vivo antibacterial activities of compound I against MRSA were further evaluated using thigh infection model and systemic infection model. Compound I possessed superior antibacterial efficacy to tiamulin against MRSA infection in both model.

SDS of cas: 73590-85-9. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, is researched, Molecular C17H19N3O2S, CAS is 73590-85-9, about The mechanism of action of the antisecretory agent omeprazole. Author is Lindberg, Per; Nordberg, Peter; Alminger, Tomas; Braendstroem, Arne; Wallmark, Bjoern.

The very potent gastric antisecretory agent omeprazole (I) [73590-58-6], presently under clin. evaluation, has been shown to act via inhibition of the gastric H+, K+-ATPase, the enzyme responsible for pumping of protons into the stomach. I needs acid activation to become an active inhibitor. A tetracyclic sulfenamide (II) was isolated from the acid decomposition of I. This sulfenamide, or, alternatively, the corresponding sulfenic acid, an unstable, probable intermediate in the sulfenamide formation, is the active inhibitor formed in vivo from omeprazole.
