Abhishek, Verma published the artcileMechanistic aspect of Iridium(III) catalyzed oxidation of ethylene glycol by Chloramine-T in aqueous acidic medium: a kinetic model, Formula: C7H13ClNNaO5S, the publication is G P Globalize Research Journal of Chemistry (2018), 1(2), 107-115, database is CAplus.

The kinetic investigation of homogeneously Ir(III) chloride catalyzed oxidation of Ethylene glycol by Chloramine- T [CAT] in perchloric acid medium has been carried out in the temperature range of 30 to 45°C. The reaction was carried out in the presence of mercuric acetate as a scavenger for chloride ion. The reaction exhibits first order kinetics with respect to the oxidant [CAT] and catalyst [Ir(III)] while zero order with respect to substrate, i.e., Ethylene glycol (EG) was observed The reaction shows negligible effect of [Hg(OAc)₂], [H⁺] and ionic strength of the medium. Chloride ion pos. influenced the rate of reaction. The various activation parameters have been calculated from the rate measurements at different temperatures (30 to 45°C). The product of the reaction has been identified as the corresponding monocarboxylic acid. The reaction between Chloramine-T and Ethylene glycol in acid medium shows 2:1 stoichiometry. On the basis of kinetic studies, reaction stoichiometry and product anal., a suitable mechanism has been proposed and rate law has been derived.

Kalindjian, S. Barret published the artcileA New Series of Orally Bioavailable Chemokine Receptor 9 (CCR9) Antagonists; Possible Agents for the Treatment of Inflammatory Bowel Disease, HPLC of Formula: 32333-53-2, the publication is Journal of Medicinal Chemistry (2016), 59(7), 3098-3111, database is CAplus and MEDLINE.

Chemokine receptor 9 (CCR9), a cell surface chemokine receptor which belongs to the G protein-coupled receptor, 7-trans-membrane superfamily, is expressed on lymphocytes in the circulation and is the key chemokine receptor that enables these cells to target the intestine. It has been proposed that CCR9 antagonism represents a means to prevent the aberrant immune response of inflammatory bowel disease in a localized and disease specific manner and one which is accessible to small mol. approaches. One possible reason why clin. studies with vercirnon, a prototype CCR9 antagonist, were not successful may be due to a relatively poor pharmacokinetic (PK) profile for the mol. We wish to describe work aimed at producing new, orally active CCR9 antagonists based on the 1,3-dioxoisoindoline skeleton. This study led to a number of compounds that were potent in the nanomolar range and which, on optimization, resulted in several possible preclin. development candidates with excellent PK properties.

Mayer, Bernhard X. published the artcileA 50% n-octylmethyl, 50% diphenyl-polysiloxane as stationary phase with unique selectivity for gas chromatography, Name: Dichloro(methyl)(octyl)silane, the publication is Analyst (Cambridge, United Kingdom) (2003), 128(10), 1238-1242, database is CAplus and MEDLINE.

An n-octylmethyl, diphenyl-polysiloxane called SOP-50-Octyl was prepared by a condensation reaction of bis(dimethylamino) n-octylmethylsilane with diphenylsilanediol. The resulting copolymer was a gum with high mol. weight and was obtained with a yield of 80%. ¹H and ²⁹Si NMR spectroscopy revealed that the copolymer was a 52% octylmethyl, 48% diphenyl-polysiloxane with random microstructure. Small cyclic impurities could be almost quant. removed via a purification step. SOP-50-Octyl was used as stationary phase for the preparation of wall coated open tubular fused silica capillary columns for gas-liquid chromatog. The capillary columns exhibited high separation efficiency and high inertness. The stationary phase offered a unique selectivity due to its unique composition The Rohrschneider-McReynolds constants indicated a low overall polarity in spite of the high Ph content, as the polarity was distinctly decreased by the octyl substituent. Also, the octyl substituent was responsible for a high column bleed, reducing the maximum allowable operating temperature to 280°. The elution temperatures of apolar compounds were increased due to increased interaction of the octyl substituent with the analytes. Some applications with volatile and semi-volatile organic compounds illustrate that SOP-50-Octyl is an excellent choice for confirmational analyses.

Comparison of pKa values for the ammonia acids Me3N+(CH2)nCO2H ClO4- (n = 1, 2, 3), I (R = 2-, 3-, 4-CO2H), and II (same R) with the pKa values for the homomorphous acids Me3C(CH2)nCO2H (n = 1, 2, 3), III (R = 2-, 3-, 4-CO2H) and IV (same R) permits an evaluation of the steric effect of the Me3N+ group. The pKa values, corrected for the steric effect, correlate with the reciprocal distance between the pos. N atom and the dissociable proton. Thus, the acidity of these acids is determined by the field effect, not the inductive effect, of the Me3N+ groups.

Burns, Mark R. published the artcileStructural correlation between lipophilicity and lipopolysaccharide-sequestering activity in spermine-sulfonamide analogs, Related Products of chlorides-buliding-blocks, the publication is Bioorganic & Medicinal Chemistry Letters (2006), 16(24), 6209-6212, database is CAplus and MEDLINE.

Lipopolysaccharides (LPS), otherwise termed endotoxins, are outer-membrane constituents of Gram-neg. bacteria, and play a key role in the pathogenesis of Septic Shock, a major cause of mortality in the critically ill patient. We had previously defined the pharmacophore necessary for small mols. to specifically bind and neutralize this complex carbohydrate. A series of aryl and aliphatic spermine-sulfonamide analogs were synthesized and tested in a series of binding and cell-based assays in order to probe the effect of lipophilicity on sequestration ability. A strong correlation was indeed found, supporting the hypothesis that endotoxin-neutralizing ability involves a lipophilic or membrane attachment event. The research discussed herein may be useful for the design of addnl. carbohydrate recognizing mols. and endotoxin-neutralizing drugs.

Chen, Yih-Ting published the artcileAcute kidney disease and acute kidney injury biomarkers in coronary care unit patients, Product Details of C12H15ClO3, the publication is BMC Nephrology (2020), 21(1), 207, database is CAplus and MEDLINE.

Background: Acute kidney disease (AKD) describes acute or subacute damage and/or loss of kidney function for a duration of between 7 and 90 days after exposure to an acute kidney injury (AKI) initiating event. This study investigated the predictive ability of AKI biomarkers in predicting AKD in coronary care unit (CCU) patients. Methods: A total of 269 (mean age: 64 years; 202 (75%) men and 67 (25%) women) patients admitted to the CCU of a tertiary care teaching hospital from Nov. 2009 to Sept. 2014 were enrolled. Information considered necessary to evaluate 31 demog., clin. and laboratory variables (including AKI biomarkers) was prospectively recorded on the first day of CCU admission for post hoc anal. as predictors of AKD. Blood and urinary samples of the enrolled patients were tested for neutrophil gelatinase-associated lipocalin (NGAL), cystatin C (CysC) and interleukin-18 (IL-18). Results: The overall hospital mortality rate was 4.8%. Of the 269 patients, 128 (47.6%) had AKD. Multivariate logistic regression anal. revealed that age, Hb, ejection fraction and serum IL-18 were independent predictors of AKD. Cumulative survival rates at 5 years of follow-up after hospital discharge differed significantly (p < 0.001) between subgroups of patients diagnosed with AKD (stage 0A, 0C, 1, 2 and 3). The overall 5-yr survival rate was 81.8% (220/269). Multivariate Cox proportional hazard anal. revealed that urine NGAL, body weight and Hb level were independent risk factors for 5-yr mortality. Conclusions: This investigation confirmed that AKI biomarkers can predict AKD in CCU patients. Age, Hb, ejection fraction and serum IL-18 were independently associated with developing AKD in the CCU patients, and urine NGAL, body weight and Hb level could predict 5-yr survival in these patients.

Hwang, Gi Won published the artcileSensitive ratiometric detection of Al(III) ions in a 100% aqueous buffered solution using a fluorescent probe based on a peptide receptor, Formula: C19H14Cl2, the publication is New Journal of Chemistry (2018), 42(2), 1437-1445, database is CAplus.

Ratiometric detection of Al(III) ions in aqueous buffered solutions is still a significant challenge. Herein, a fluorescent probe [1-pyrenyl]-CH₂CO-L-Ser-L-Asp-OH (I) based on a dipeptide receptor bearing a pyrene fluorophore was synthesized by solid phase synthesis for the ratiometric detection of Al(III) ions in aqueous solutions The peptidyl bioprobe detected Al(III) ions sensitively in a 100% aqueous buffered solution through ratiometric response. Upon the addition of Al(III) ions, the excimer emission at 476 nm increased significantly, and the monomer emission at 395 nm decreased considerably. Approx. 3.5 equiv of Al(III) was required for the complete ratiometric response of I. Also, I showed linear responses to nanomolar concentrations (0-500 nM) of Al(III) by change in the intensity ratio of the excimer and monomer emissions. The detection limit of I for Al(III) was 138.1 nM (R² = 0.980) in 100% aqueous solutions The probe showed highly selective response to Al(III) in the presence of 16 metal ions. The fluorescent peptidyl probe was suitable for the ratiometric detection of Al(III) ions in ground water, tap water, and urine.

A transition-metal-free, t-BuOOH mediated intramol. carbonylation of arenes in 2-aryl-3-picolines via oxidative C-H functionalizations of the Me group has been developed, providing an expedient synthesis of 4-azafluorenones I [R = 7-MeO, 7-OCF₃, 6,7-Cl₂, 6-Cl-7-OPr-i, 7,8-(OMe)₂, etc] . Distinct from the current literature wherein methylarenes have been used as acylating agents, 2-aryl-3-picolines in this study are transformed into aldehydes, which give 4-azafluorenones upon rapid intramol. acylation. The study demonstrates the first example of intramol. carbonylation of arenes utilizing a Me group as latent carbonyl functionality.
