Reference of 102029-44-7, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 102029-44-7, Name is (R)-4-Benzyl-2-oxazolidinone,introducing its new discovery.

The serine/threonine kinase CK2 modulates the activity of more than 300 proteins and thus plays a crucial role in various physiological and pathophysiological processes including neurodegenerative disorders of the central nervous system and cancer. The enzymatic activity of CK2 is controlled by the equilibrium between the heterotetrameric holoenzyme CK2alpha2beta2 and its monomeric subunits CK2alpha and CK2beta. A series of analogues of W16 ((3aR,4S,10S,10aS)-4-{[(S)-4-benzyl-2-oxo-1,3-oxazolidin-3-yl]carbonyl}-10-(3,4,5-trimethoxyphenyl)-4,5,10,10a-tetrahydrofuro[3,4-b]carbazole-1,3(3aH)-dione ((+)-3 a)) was prepared in an one-pot, three-component Levy reaction. The stereochemistry of the tetracyclic compounds was analyzed. Additionally, the chemically labile anhydride structure of the furocarbazoles 3 was replaced by a more stable imide (9) and N-methylimide (10) substructure. The enantiomer (?)-3 a (Ki=4.9 muM) of the lead compound (+)-3 a (Ki=31 muM) showed a more than sixfold increased inhibition of the CK2alpha/CK2beta interaction (protein-protein interaction inhibition, PPII) in a microscale thermophoresis (MST) assay. However, (?)-3 a did not show an increased enzyme inhibition of the CK2alpha2beta2 holoenzyme, the CK2alpha subunit or the mutated CK2alpha? C336S subunit in the capillary electrophoresis assay. In the pyrrolocarbazole series, the imide (?)-9 a (Ki=3.6 muM) and the N-methylimide (+)-10 a (Ki=2.8 muM) represent the most promising inhibitors of the CK2alpha/CK2beta interaction. However, neither compound could inhibit enzymatic activity. Unexpectedly, the racemic tetracyclic pyrrolocarbazole (±)-12, with a carboxy moiety in the 4-position, displays the highest CK2alpha/CK2beta interaction inhibition (Ki=1.8 muM) of this series of compounds.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 497-25-6, name is Oxazolidin-2-one, introducing its new discovery. category: oxazolidine

(Chemical Equation Presented) A series of 4-bicyclic heteroaryl 1,2,3,4-tetrahydroisoquinoline inhibitors of the serotonin transporter (SERT), norepinephrine transporter (NET), and dopamine transporter (DAT) was discovered. The synthesis and structure-activity relationship (SAR) of these triple reuptake inhibitors (TRIs) will be discussed. Compound 10i (AMR-2), a very potent inhibitor of SERT, NET, and DAT, showed efficacy in the rat forced-swim and mouse tail suspension models with minimum e ffective doses of 0.3 and 1 mg/kg (po), respectively. At efficacious doses in these assays, 10i exhibited substantial occupancy levels at the three transporters in both rat and mouse brain. The study of the metabolism of 10i revealed the formation of a significant active metabolite, compound 13.

Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 497-25-6, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 497-25-6

In this paper, standard molar energies of combustion of 2-oxazolidinone and 3-acetyl-2-oxazolidinone are reported. The experimental values, obtained from static-bomb combustion calorimetry, are ?(1465.42 ± 0.52) kJ·mol?1and ?(2350.86 ± 0.84) kJ·mol?1, respectively. Using these combustion energy values, the standard molar enthalpies of formation, in crystalline phase, for the aforesaid compounds were calculated. These values were also determined, and the corresponding values are ?(430.30 ± 0.96) kJ·mol?1and ?(617.72 ± 1.58) kJ·mol?1, respectively. The standard molar enthalpies of sublimation at T = 298.15 K were experimentally obtained by using the well-known Knudsen effusion method. The obtained values are (84.20 ± 3.22) kJ·mol?1and (82.36 ± 1.84) kJ·mol?1, respectively. From the above experimental results, the standard molar enthalpies of formation in gas-phase of the compounds were derived. The values are: ?(346.10 ± 3.36) kJ·mol?1and ?(535.36 ± 2.43) kJ·mol?1, respectively. To support the consistency of the experimental results presented here, enthalpies of formation in gas-phase, using the G4 composite method, were carried out as well. Experimental results suggest that the formation of intermolecular hydrogen bonds between the nitrogen (at ring’s position 3, see Fig. 1) with the oxygen (at ring’s position 2, see Fig. 1) contributes to the values of temperature and enthalpy of fusion, enthalpy of sublimation, and enthalpy of formation in solid phase.

Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. Formula: C10H11NO2. Introducing a new discovery about 102029-44-7, Name is (R)-4-Benzyl-2-oxazolidinone

(Chemical Equation Presented) A de novo preparation of alpha-keto-imides via ynamide oxidation is described. With a number of alkyne oxidation conditions screened, a highly efficient RuO2-NaIO4 mediated oxidation and a DMDO oxidation have been identified to tolerate a wide range of ynamide types. In addition to accessing a wide variety of alpha-keto-imides, the RuO2-NaIO4 protocol provides a novel entry to the vicinal tricarbonyl motif via oxidation of push-pull ynamides, and imido acylsilanes from silyl-substituted ynamides. Chemoselective oxidation of ynamides containing olefins can be achieved by using DMDO, while the RuO 2-NaIO4 protocol is not effective. These studies provide further support for the synthetic utility of ynamides.

Nickel(0)-promoted carboxylation of N-allenylamides (allenamides) with carbon dioxide proceeded via a nickelalactone intermediate to give beta-amino acid derivatives. It was also found that the regioselectivity at the oxidative addition stage was strongly affected by the substituents on the allene part. Georg Thieme Verlag Stuttgart. New York.

A series of novel, potent, and selective human beta2 adrenoceptor agonists incorporating a sulfone moiety on the terminal right-hand-side phenyl ring of (R)-salmeterol is presented. Sulfone 10b had salmeterol-like potency and selectivity profile, long duration of action on guinea pig trachea, and longer than salmeterol duration of action in vivo, suitable for once-daily dosing. It had lower than salmeterol oral absorption in rat, lower bioavailability in rat and dog, and a high turnover in human hepatocytes. It was metabolized in human hepatocytes by hydroxylation, oxidation, cleavage, and conjugation; most of the metabolites would be expected to have reduced or no beta2 activity. The 4-biphenylsulfonic acid was identified as a crystalline, non-hygroscopic salt of 10b, suitable for inhaled delivery. Furthermore, it was free of any genetic toxicity issues and was considered as a backup to vilanterol.

The samarium diiodide-promoted reduction of 2-deoxy-2-acetamidogalactosyl pyridyl sulfone alpha-5 with ketones or aldehydes under Barbier conditions led unexpectedly to the stereoselective synthesis of alpha-C-galactosamine derivatives in good yields. With carbonyl substrates, alpha:beta selectivities ranged from 20:1 to 5:1, and with aldehydes a stereoselectivity of approximately 5:1 was observed at C7 in favor of the S-isomer. The stereochemical preference of these C-glycosylation reactions is explained by the intermediacy of an alpha-oriented anomeric glycosyl samarium(III) compound that is stabilized via chelation of the metal ion to the C2-acetamido group.
