In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Pharmacokinetics of [14C]omeprazole in patients with impaired renal function., published in 1986, which mentions a compound: 73590-85-9, mainly applied to , Product Details of 73590-85-9.

Pharmacokinetics of [14C]omeprazole and its metabolites were studied after single intravenous and oral doses of 20 and 40 mg, respectively, to 12 patients with chronic renal insufficiency. Blood samples for determination of total radioactivity, omeprazole, OH-omeprazole, sulfone, and sulfide were taken for 24 hours. Urine was collected over 96 hours for determination of total radioactivity and during the first 24 hours for additional assay of omeprazole and metabolites. The mean systemic availability was 70%. The mean plasma t1/2 of omeprazole was 0.6 hours. Unchanged omeprazole was not measurable in urine. Derived pharmacokinetic constants of intact omeprazole were within the range of those reported in healthy individuals. The accumulated 24-hour excretion of radioactive metabolites was related significantly to creatinine clearance. The cumulative excretion of total radioactivity in urine over 96 hours in percent of given dose varied between 25% and 83%.

Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:56621-48-8) through the article.

Electrochem. oxidation of some p-aminophenol derivatives (1-5) in acidic solutions was studied both exptl. and theor. to provide insight into the influence of some factors on the hydrolysis reaction rate. The result of this work shows that the electrogenerated p-quinoneimines participate in the hydrolysis reaction and are converted to the p-benzoquinone. The hydrolysis reaction rate strongly depends on the structure of the p-aminophenols and solution’s pH. The observed homogeneous rate constants of hydrolysis (kobshyd) of p-quinoneimines were determined using digital simulation technique. The effect of different parameters such as: change of Gibbs free energy (ΔG) of the electrochem. oxidation of para-aminophenol derivatives (1-5), charge of reaction site, N-C4 bond order (Wiberg Bond Indexes, WBIs) and the nature of substituted group, on the hydrolysis rate constant were also studied. All calculations were performed using D. Functional Theory (DFT) both BP86 and B3LYP levels of theory and 6-311G (p,d) basis set. The N-C4 bond order and charge on the reaction site play significant roles in hydrolysis reaction’s rate.

Omeprazole  [73590-58-6], a substituted benzimidazole which suppresses gastric acid secretion, and its sulfone [88546-55-8] and sulfide [73590-85-9] metabolites were simultaneously measured in human plasma and urine using a selective, reversed-phase, high-performance liquid chromatog. method with a sensitivity of 5 ng/mL for omeprazole, 30 ng/mL for omeprazole sulfone, and 50 ng/mL for omeprazole sulfide. The coefficients of variation for within-day assays were 4.4, 7.5, and 17.5%, resp. In a pilot pharmacokinetic study, 40 mg of omeprazole (encapsulated enteric-coated granules) were administered to 2 healthy volunteers. Peak plasma concentrations for omeprazole of 240 and 520 ng/mL, and for omeprazole sulfone of 320 and 400 ng/mL, were reached between 3 and 4 post-dose. Omeprazole concentrations fell rapidly with apparent half-lives of about 40 min, and concentrations of both omeprazole and the sulfone metabolite were below the minimal detectable level by 6-8 h.

The in vitro antibacterial activities of these derivatives against Staphylococcus aureus and Escherichia coli were tested by the agar dilution method. Structure-activity relationship studies resulted in compounds 11b (R = 3-MeOC6H4), 13b (R = 3-HOC6H4), and 14a (R = 2-NO2C6H4) with the most potent in vitro antibacterial activity among the series (minimal inhibitory concentration of 0.0625-0.125 μg/mL). The binding of compounds 11b, 13b, and 14a to the E. coli ribosome was investigated by mol. modeling, and it was found that there is a reasonable correlation between the binding free energy and the antibacterial activity.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions.

A series of novel arylpiperazines bearing a pyrrolidin-2-one fragment was synthesized and evaluated for the binding affinity of the α1- and α2-adrenoceptors (AR) and for the antiarrhythmic and hypotensive activities of the compounds The most potent and selective compound 1-[2-hydroxy-3-[4-[(2-hydroxyphenyl)piperazin-1-yl]propyl]pyrrolidin-2-one 8 binds with pKi = 6.71 for α1-AR. Derivative 8 (I) was also the most active in the prophylactic antiarrhythmic test in adrenaline-induced arrhythmia in anesthetized rats. Its ED50 value equals 1.9 mg/kg (i.v.). Compounds with substituents such as a fluorine atom 4, a Me 5, or a hydroxyl 8 group, or two substituents such as fluorine/chlorine atoms and methoxy groups in the Ph ring, significantly decreased the systolic and diastolic pressure in normotensive anesthetized rats at a dosages of 5-10 mg/kg (i.v.). It was found that the presence of the piperazine ring and a hydroxy group in the second position of the Pr chain are critical structural features in determining the affinity of the compounds tested.

Related Products of 73590-85-9. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, is researched, Molecular C17H19N3O2S, CAS is 73590-85-9, about High-performance liquid chromatographic assay for human liver microsomal omeprazole metabolism. Author is Andersson, Tommy; Lagerstroem, Per Olof; Miners, John O.; Veronese, Maurice E.; Weidorf, Lars; Birkett, Donald J..

Assays for the measurement of omeprazole metabolites in plasma and urine were reported, but when applied to the determination of omeprazole metabolites formed by human liver microsomal incubations, there were obvious limitations in sensitivity. The present HPLC assay, which comprises extraction, evaporation and reconstitution, is several-fold more sensitive with a limit of detection of ∼ 2 pmol (2 nM in incubate) for omeprazole sulfone and 25 pmol (25 nM in incubate) for hydroxyomeprazole. Extraction efficiency is essentially quant. and is highly reproducible (coefficient of variation = 2.1% for both metabolites). The assay is linear over a wide range of concentrations and the formation of the metabolites is linear with respect to both time (to 15 min) and protein concentration (to 1.5 mg/mL). Two minor metabolites, 1 of which was identified tentatively as 5-O-desmethylomeprazole, were also formed by human liver microsomes and could be determined by this method. Preliminary studies of the formation of omeprazole sulfone and hydroxyomeprazole showed that the formation kinetics in human liver microsomes were biphasic for both metabolites, suggesting that at least 2 different cytochrome P 450 isoforms are involved in their formation.
