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 SuFEx-enabled, chemoselective synthesis of triflates, triflamides and triflimidates, published in 2022, which mentions a compound: 56621-48-8, mainly applied to aryltriflate preparation; aryltriflamide preparation; aryltriflimidate preparation; aryl amide preparation, Recommanded Product: 4-(Piperazin-1-yl)phenol.

The ex-situ generation of trifluoromethanesulfonyl fluoride (CF3SO2F) gas in a two chamber system, and its use as a new SuFEx handle to efficiently synthesize triflates and triflamides were reported. This broadly tolerated protocol lends itself to peptide modification or to telescoping into coupling reactions. Moreover, redesigning the SVI-F connector with a S=O → S=NR replacement furnished the analogous triflimidoyl fluorides as SuFEx electrophiles, which were engaged in the synthesis of rarely reported triflimidate esters. Notably, experiments showed H2O to be the key towards achieving chemoselective trifluoromethanesulfonation of phenols vs. amine groups, a phenomenon best explained-using ab initio metadynamics simulations-by a hydrogen bonded termol. transition state for the CF3SO2F triflylation of amines.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Simultaneous high-performance liquid chromatographic analysis of omeprazole and its sulfone and sulfide metabolites in human plasma and urine, published in 1983-12-09, which mentions a compound: 73590-85-9, Name is 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole, Molecular C17H19N3O2S, Reference of 5-Methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole.

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. Omeprazole sulfide could not be detected in this study.

Product Details of 56621-48-8. 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 Itraconazole Side Chain Analogues: Structure-Activity Relationship Studies for Inhibition of Endothelial Cell Proliferation, Vascular Endothelial Growth Factor Receptor 2 (VEGFR2) Glycosylation, and Hedgehog Signaling. Author is Shi, Wei; Nacev, Benjamin A.; Aftab, Blake T.; Head, Sarah; Rudin, Charles M.; Liu, Jun O..

Itraconazole is an antifungal drug that was recently found to possess potent antiangiogenic activity and anti-hedgehog (Hh) pathway activity. To search for analogs of itraconazole with greater potency and to understand the structure-activity relationship in both antiangiogenic and Hh targeting activity, 25 itraconazole side chain analogs were synthesized and assayed for inhibition of endothelial cell proliferation and Gli1 transcription in a medulloblastoma (MB) culture. Through this anal., we have identified analogs with increased potency for inhibiting endothelial cell proliferation and the Hh pathway, as well as VEGFR2 glycosylation that was recently found to be inhibited by itraconazole. An SAR anal. of these activities revealed that potent activity of the analogs against VEGFR2 glycosylation was generally driven by side chains of at least four carbons in composition with branching at the α or β position. SAR trends for targeting the Hh pathway were divergent from those related to HUVEC proliferation or VEGFR2 glycosylation. These results also suggest that modification of the sec-Bu side chain can lead to enhancement of the biol. activity of itraconazole.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 56621-48-8, is researched, Molecular C10H14N2O, about Ordered Layered Dendrimers Constructed from Two Known Dendrimer Families: Inheritance and Emergence of Properties, the main research direction is triazine piperazine dendrimer; dendrimers; electrochemistry; phosphorus; piperazine; triazines.Category: ethers-buliding-blocks.

A new concept is presented, namely the synthesis of dendrimers intrinsically composed in alternation of building blocks pertaining to two known families of dendrimers: phosphorhydrazone dendrimers and triazine-piperazine dendrimers. These mixed dendrimers with layered controlled architecture inherit their easy 31P NMR characterization and their thermal stability from the phosphorhydrazone family, and their decreased solubility from the triazine-piperazine family. However, they have also their own and original characteristics. Both parent families are white powders, whereas the mixed dendrimers are yellow, orange, or red powders, depending on the generation. DFT calculations were carried out on model dendrons to understand these special color features. Remarkably, these dendrimers incorporating redox-active organic entities allow for the first time the monitoring of the growth of an organic dendrimer by electrochem. while highlighting an even-odd generation behavior.

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, Article, Journal of Chromatography, Biomedical Applications called 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., which mentions a compound: 73590-85-9, SMILESS is CC1=CN=C(CSC2=NC3=CC(OC)=CC=C3N2)C(C)=C1OC, Molecular C17H19N3O2S, HPLC of Formula: 73590-85-9.

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.

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 Disposition of the anti-ulcer medications ranitidine, cimetidine, and omeprazole following administration of multiple doses to exercised Thoroughbred horses, published in 2017, which mentions a compound: 73590-85-9, mainly applied to antiulcer ranitidine cimetidine omeprazole pharmacokinetics, Category: ethers-buliding-blocks.

The use of anti-ulcer medications, such as cimetidine, ranitidine, and omeprazole, is common in performance horses. The use of these drugs is regulated in performance horses, and as such a withdrawal time is necessary prior to competition to avoid a medication violation. To the authors’ knowledge, there are no reports in the literature describing repeated oral administrations of these drugs in the horse to determine a regulatory threshold and related withdrawal time recommendations. Therefore, the objective of the current study was to describe the disposition and elimination pharmacokinetics of these anti-ulcer medications following oral administration to provide data upon which appropriate regulatory recommendations can be established. Nine exercised Thoroughbred horses were administered 20 mg/kg BID of cimetidine or 8 mg/kg BID of ranitidine, both for seven doses or 2.28 g of omeprazole SID for four doses. Blood samples were collected, serum drug concentrations were determined, and elimination pharmacokinetic parameters were calculated The serum elimination half-life was 7.05 ± 1.02, 7.43 ± 0.851 and 3.94 ± 1.04 h for cimetidine, ranitidine, and omeprazole, resp. Serum cimetidine and ranitidine concentrations were above the LOQ and omeprazole and omeprazole sulfide below the LOQ in all horses studied upon termination of sample collection.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 56621-48-8, is researched, Molecular C10H14N2O, about Platinum(II) dithiocarbamate complexes [Pt(S2CNR2)Cl(PAr3)] as anticancer and DNA-damaging agents, the main research direction is platinum dithiocarbamate complex preparation anticancer DNA binding; optimized mol structure platinum dithiocarbamate complex.Computed Properties of C10H14N2O.

Following the fortunate discovery of cisplatin as an anticancer drug the search for new effective Pt-containing analogs with high potency but reduced side effects and resistance is of great importance. Herein, we report four new monofunctional platinum(II) dithiocarbamate complexes, [Pt(S2CNR2)Cl(PAr3)], and their activity against selected cancer cell lines. DFT-optimized structures reveal steric hindrance, similar to phenanthriplatin, from an axial C-H site of the triarylphosphine. High activity against selected cancer cell lines, MCF-7 > LU > Hepa-IcIc7, can be attributed to the axial protection offered by the aromatic C-H moiety, together with the lipophilicity and formation of bulkier and more hydrophobic DNA adducts. DNA binding, denaturing and plasmid cleavage studies demonstrate their potential to cleave DNA via electrostatic or covalent interactions. DFT and exptl. studies show the ability to replace chloride with different nucleophiles; substitution with smaller nucleophiles being fast while with larger nucleophiles is slow.
