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.

The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate.

A novel gradient reversed-phase ultra performance liquid chromatog. method has been developed for quant. determination of Esomeprazole magnesium and its seven impurities in pharmaceutical dosage forms. Chromatog. separation has been achieved on an Acquity BEH C18, 50 mm × 2.1 mm, 1.7 μm with buffered mobile phase consisting solvent A (0.04 M (M) glycine (pH 9.0) buffer) and solvent B (mixture of acetonitrile and Milli-Q water in the ratio 90: 10 (volume/volume); resp.) delivered at flow rate of 0.21 mL min-1 and the detection wavelength 305 nm. Resolution of Esomeprazole magnesium and all the seven potential impurities has been achieved greater than 2.0 for all pairs of compounds The drug was subjected to the stress conditions of oxidative, acid, base, hydrolytic, thermal and photolytic degradation Esomeprazole magnesium was found to degrade significantly in oxidative and acid hydrolysis stress conditions and stable in base, hydrolytic and photolytic degradation conditions. The degradation products were well resolved from main peak and its impurities, thus proved the stability indicating power of the method. The stress samples were assayed against a reference standard and the mass balance was found to be close to 99.1%. So this method was also suitable for Assay determination of Esomeprazole magnesium in pharmaceutical dosage forms. The developed method was validated as per ICH guidelines with respect to specificity, linearity, limit of detection, limit of quantification, accuracy, precision and robustness.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole(SMILESS: CC1=CN=C(CSC2=NC3=CC(OC)=CC=C3N2)C(C)=C1OC,cas:73590-85-9) is researched.HPLC of Formula: 591-12-8. The article 《Regioselective C-H hydroxylation of omeprazole sulfide by Bacillus megaterium CYP102A1 to produce a human metabolite》 in relation to this compound, is published in Biotechnology Letters. Let’s take a look at the latest research on this compound (cas:73590-85-9).

Objectives: To find a simple enzymic strategy for the efficient synthesis of the expensive 5′-hydroxyomeprazole sulfide, a recently identified minor human metabolite, from omeprazole sulfide, which is an inexpensive substrate. Results: The practical synthetic strategy for the 5′-OH omeprazole sulfide was accomplished with a set of highly active CYP102A1 mutants, which were obtained by blue colony screening from CYP102A1 libraries with a high conversion yield. The mutant and even the wild-type enzyme of CYP102A1 catalyzed the high regioselective (98 %) C-H hydroxylation of omeprazole sulfide to 5′-OH omeprazole sulfide with a high conversion yield (85-90 %). Conclusions: A highly efficient synthesis of 5′-OH omeprazole sulfide was developed using CYP102A1 from Bacillus megaterium as a biocatalyst.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain 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 Investigating the presence of omeprazole in waters by liquid chromatography coupled to low and high resolution mass spectrometry: degradation experiments, the main research direction is omeprazole water liquid chromatog mass spectrometry degradation; omeprazole; surface water; time-of-flight mass spectrometry; transformation/degradation products; triple quadrupole mass spectrometry; ultra-high-performance liquid chromatography; urban wastewater.COA of Formula: C17H19N3O2S.

Omeprazole is one of the most consumed pharmaceuticals around the world. However, this compound is scarcely detected in urban wastewater and surface water. The absence of this pharmaceutical in the aquatic ecosystem might be due to its degradation in wastewater treatment plants, as well as in receiving water. Different laboratory-controlled degradation experiments were carried out on surface water to elucidate omeprazole transformation products (TPs). Surface water spiked with omeprazole was subjected to hydrolysis, photo-degradation under both sunlight and UV radiation and chlorination. Analyses by liquid chromatog. coupled to quadrupole time-of-flight mass spectrometry (LC-QTOF MS) permitted identification of ≤17 omeprazole TPs. In a subsequent step, the TPs identified were sought in surface water and urban wastewater by LC-QTOF MS and by LC coupled to tandem mass spectrometry with triple quadrupole. The parent omeprazole was not detected in any of the samples, but 4 TPs were found in several water samples. The most frequently detected compound was OTP 5 (omeprazole sulfide), which might be a reasonable candidate to be included in monitoring programs rather than the parent omeprazole.

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 , Quality Control of 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole.

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%.

Recommanded Product: 73590-85-9. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. 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.

There is still a lot of research devoted to this compound(SMILES：CC1=CN=C(CSC2=NC3=CC(OC)=CC=C3N2)C(C)=C1OC)Recommanded Product: 73590-85-9, and with the development of science, more effects of this compound(73590-85-9) can be discovered.

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.
