Kaiser, Emil Thomas; Lo, Kwok-Wing published an article in 1969, the title of the article was Carbonic anhydrase catalyzed hydrolysis of 2-hydroxy-5-nitro-α-toluenesulfonic acid sultone.Application of 97-09-6 And the article contains the following content:

An ionizable group in bovine carbonic anhydrase (BCA) with a pK of 7.3 appears to be involved in the enzyme-catalyzed hydrolysis of 2-hydroxy-5-nitro-α-toluenesulfonic acid sultone (I). Similar observations have been reported previously for the pH-rate behavior of the BCA-catalyzed hydration of CO2, hydration of carbonyl compounds, and hydrolysis of nitrophenyl esters of carboxylic acids. The BCA-catalyzed hydrolysis of I is subject to sulfonamide inhibition as are the other reactions mentioned above. Also, human carbonic anhydrases B and C have been demonstrated to be effective catalysts for the hydrolysis of I. On the basis of observations taken in conjunction with those of other investigations, it is proposed that a Zn-bound hydroxide ion is the active catalytic species in carbonic anhydrase action, and a cyclic mechanism for the carbonic anhydrase catalyzed solvolysis of I, involving no net proton transfer to the solvent is suggested. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Application of 97-09-6

And the article contained the following:

In our drug discovery program of natural product, earlier we have reported Aegeline that is N-acylated-1-amino-2- alc., which was isolated from the leaves of Aeglemarmelos showed anti-hyperlipidemic activity for which the QSAR studies predicted the compound to be the β3-AR agonist, but the mechanism of its action was not elucidated. In our present study, we have evaluated the β3-AR activity of novel N-acyl-1-amino-3-arylopropanol synthetic mimics of aegeline and its beneficial effect in insulin resistance. In this study, we have proposed the novel pharmacophore model using reported mols. for antihyperlipidemic activity. The reported pharmacophore features were also compared with the newly developed pharmacophore model for the observed biol. activity. Based on 3D pharmacophore modeling of known β3AR agonist, we screened 20 synthetic derivatives of Aegeline from the literature. From these, the top scoring compound 10C was used for further studies. The in-slico result was further validated in HEK293T cells co-trransfected with human β3-AR and CRE-Luciferase reporter plasmid for β3-AR activity. The most active compound was selected and β3-AR activity was further validated in white and brown adipocytes differentiated from human mesenchymal stem cells (hMSCs). Insulin resistance model developed in hMSC derived adipocytes was used to study the insulin sensitizing property. 8week HFD fed C57BL6 mice was given 50mg/Kg of the selected compound and metabolic phenotyping was done to evaluate its anti-diabetic effect. As predicted by in-silico 3D pharmacophore modeling, the compound 10C was found to be the most active and specific β3-AR agonist with EC50 value of 447nM. The compound 10C activated β3AR pathway, induced lipolysis, fatty acid oxidation and increased oxygen consumption rate (OCR) in human adipocytes. Compound 10C induced expression of brown adipocytes specific markers and reverted chronic insulin induced insulin resistance in white adipocytes. The compound 10C also improved insulin sensitivity and glucose tolerance in 8week HFD fed C57BL6 mice. This study enlightens the use of in vitro insulin resistance model close to human physiol. to elucidates the insulin sensitizing activity of the compound 10C and edifies the use of β3AR agonist as therapeutic interventions for insulin resistance and type 2 diabetes.

King, Rodney William; Burgen, Arnold S. V. published an article in 1970, the title of the article was Sulfonamide complexes of human carbonic anhydrases ultraviolet difference spectroscopy.Recommanded Product: 3-Nitro-4-chlorobenzenesulfonamide And the article contains the following content:

Uv difference spectra are generated when human carbonic anhydrases B or C form complexes with aromatic sulfonamides. Difference spectra obtained using a variety of ring-substituted benzene sulfonamides show certain constant features; a broad peak, λmax 294-299 nm, a trough at 290-291 nm, a peak at 285-287 nm, and a peak at 232-234 nm. All the spectra obtained had other features, varying from sulfonamide to sulfonamide, not normally associated with protein perturbation difference spectra. A pH study using p-nitrobenzene sulfonamide has shown that these addnl. features may be accounted for by the dissociation of a proton from the amido group of the sulfonamide, causing changes in the uv absorption of the sulfonamide on formation of the complex. These results indicate that a conformational change takes place in the enzyme on binding the sulfonamide, exposing aromatic residues to the solvent, and that in the complex the sulfonamide is in the anionic state.

Singh, Abhilasha; Srinivasan, Ashok Kumar; Chakrapani, Lakshmi Narasimhan; Kalaiselvi, Periandavan published an article in 2019, the title of the article was LOX-1, the common therapeutic target in hypercholesterolemia: a new perspective of antiatherosclerotic action of aegeline.Related Products of 456-12-2 And the article contains the following content:

Background. Lectin-like oxidized low-d. lipoprotein receptor-1 (LOX-1) is the major receptor for oxidized low-d. lipoprotein (Ox-LDL) in the aorta of aged rats. Ox-LDL initiates LOX-1 activation in the endothelium of lipid-accumulating sites of both animal and human subjects of hypercholesterolemia. Targeting LOX-1 may provide a novel diagnostic strategy towards hypercholesterolemia and vascular diseases. Hypothesis. This study was planned to address whether aegeline (AG) could bind to LOX-1 with a higher affinity and modulate the uptake of Ox-LDL in hypercholesterolemia. Study Design. Thirty-six Wistar rats were divided into six groups. The pathol. group rats were fed with high-cholesterol diet (HCD) for 45 days, and the treatment group rats were fed with HCD and aegeline/atorvastatin (AV) for the last 30 days. In vivo and in vitro experiments were carried out to assay the markers of atherosclerosis like Ox-LDL and LOX-1 levels. Histopathol. examination was performed. Oil Red O staining was carried out in the IC-21 cell line. Docking studies were performed. Results. AG administration effectively brought down the lipid levels induced by HCD. The lowered levels of Ox-LDL and LOX-1 in AG-administered rats deem it to be a potent antihypercholesterolemic agent. Compared to AV, AG had a pronounced effect in downregulating the expression of lipids evidenced by Oil Red O staining. AG binds with LOX-1 at a higher affinity validated by docking. Conclusion. This study validates AG to be an effective stratagem in bringing down the lipid stress induced by HCD and can be deemed as an antihypercholesterolemic agent. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).Related Products of 456-12-2

On November 15, 2013, Karmase, Aniket; Jagtap, Sneha; Bhutani, Kamlesh K published an article.Category: amides-buliding-blocks The title of the article was Anti adipogenic activity of Aegle marmelos Correa.. And the article contained the following:

In continuation of evaluating the anti-obesity effect of Aegle marmelos, we have screened the n-hexane, dichloro methane (DCM), ethyl acetate (EtOAc) and methanol (MeOH) extracts of the leaves at the concentration of 25, 50, 75 and 100 μg/ml for adipogenesis inhibition in the adipocytes. Nile red staining with the help of fluorometry was used as indicator of the antiobesity activity. The most active DCM extract showed the 33.98±3.55% lipid content at 100μg/ml and was selected for the further isolation. 14 compounds were isolated from DCM extract of A. marmelos leaves. The compounds were screened for the adipogenesis inhibition at 50 and 100 μM concentrations. Out of the 14 compounds, halfordinol, ethyl ether aegeline and esculetin were showing 10.04±0.52, 16.29±0.85 and 25.09±1.31% lipid content respectively at 100 μM. We hereby report the adipogenesis inhibition by A. marmelos as one of the pathway for its antiobesity effect.

Klontz, Karl C; DeBeck, Heidi J; LeBlanc, Pamela; Mogen, Kathryn M; Wolpert, Beverly J; Sabo, Jonathan L; Salter, Monique; Seelman, Sharon L; Lance, Susan E; Monahan, Caitlin; Steigman, David S; Gensheimer, Kathleen published an article in 2015, the title of the article was The Role of Adverse Event Reporting in the FDA Response to a Multistate Outbreak of Liver Disease Associated with a Dietary Supplement..Formula: C18H19NO3 And the article contains the following content:

OBJECTIVE: Liver disease is a potential complication from using dietary supplements. This study investigated an outbreak of non-viral liver disease associated with the use of OxyELITE Pro(TM), a dietary supplement used for weight loss and/or muscle building. METHODS: Illness details were ascertained from MedWatch reports submitted to the U.S. Food and Drug Administration (FDA) describing consumers who ingested OxyELITE Pro alone or in combination with other dietary supplements. FDA’s Forensic Chemistry Center analyzed samples of OxyELITE Pro. RESULTS: From February 2012 to February 2014, FDA received 114 reports of adverse events of all kinds involving consumers who ingested OxyELITE Pro. The onset of illness for the first report was December 2010 and for the last report was January 2014. Thirty-three states, two foreign nations, and Puerto Rico submitted reports. Fifty-five of the reports (48%) described liver disease in the absence of viral infection, gallbladder disease, autoimmune disease, or other known causes of liver damage. A total of 33 (60%) of these patients were hospitalized, and three underwent liver transplantation. In early 2013, OxyELITE Pro products entered the market with a formulation distinct from products sold previously. The new formulation replaced 1,3-dimethylamylamine with aegeline. However, the manufacturer failed to submit to FDA a required “new dietary ingredient” notice for the use of aegeline in OxyELITE Pro products. Laboratory analysis identified no drugs, poisons, pharmaceuticals, toxic metals, usnic acid, N-Nitroso-fenfluramine, pyrrolizidine alkaloids, aristocholic acid, or phenethylamines in the products. CONCLUSIONS: Vigilant surveillance is required for adverse events linked to the use of dietary supplements.

On January 24, 2019, Wyss, Thomas; Roos, Lilian; Studer, Fabian; Mäder, Urs; Beuchat, Christiane; Staub, Kaspar published an article.Computed Properties of 456-12-2 The title of the article was Development of physical fitness performance in young Swiss men from 2006 to 2015.. And the article contained the following:

From 1980 to 2000, physical fitness decreased and body mass index (BMI) increased in the population of many industrialized countries. Little is known about these trends after the year 2000. This study aimed to investigate physical fitness performance, physical activity (PA) behavior, and BMI of young, male Swiss adults between 2006 and 2015. For this purpose, results from the Swiss Armed Forces mandatory recruitment were used. A total of 306 746 male conscripts provided complete fitness test data, mean ± SD (range from 5th to 95th percentile): 20 ± 1 (18-21) years, 178 ± 7 (168-189) cm; 74 ± 13 (58-97) kg, predicted maximal oxygen consumption of 49.9 ± 4.6 (41.8-56.9) mL/kg/min (Conconi test), 125 ± 58 (43-232) seconds in trunk muscle strength test (prone bridge), 2.31 ± 0.24 (1.90-2.66) m in standing long jump, 6.46 ± 0.73 (5.30-7.70) m in seated shot put (2 kg medical-ball shot) and 45.6 ± 12.2 (29.9-66.7) seconds in one-leg standing test (sum of both legs; eyes closed after 10 seconds and head tilted back after 20 seconds). In the investigated population, 73.8% fulfilled basic PA recommendations, 46.2% were classified as regularly vigorously active. Performances in aerobic endurance and muscle power did not show secular changes over time. However, core stability performance and PA behavior increased, while balance ability decreased over this 10-year period. Average BMI increased by 2.0% between 2006 and 2010 and did not change thereafter. Male Swiss adults are at least as physically fit as they were a decade ago. The secular trends of decreasing physical performances and increasing BMI have stopped, and self-reported sport participation and leisure time PA have been increased in the observed population over the last 10 years. The experimental process involved the reaction of N-(2-Hydroxy-2-(4-methoxyphenyl)ethyl)cinnamamide(cas: 456-12-2).Computed Properties of 456-12-2

On July 9, 2022, Itelman, Edward; Vatury, Ori; Kuperstein, Rafael; Ben-Zekry, Sagit; Hay, Ilan; Fefer, Paul; Barbash, Israel; Klempfner, Robert; Segev, Amit; Feinberg, Micha; Guetta, Victor; Maor, Elad published an article.Quality Control of 3-Nitro-4-chlorobenzenesulfonamide The title of the article was The Association of Severe Tricuspid Regurgitation with Poor Survival Is Modified by Right Ventricular Pressure and Function: Insights from SHEBAHEART Big Data.. And the article contained the following:

BACKGROUND: Contemporary data on the independent association of severe tricuspid regurgitation (TR) with excess mortality are needed. The aims of this study were to describe contemporary outcomes of patients with severe TR and to identify outcome modifiers. METHODS: Consecutive echocardiographic reports linked to clinical data from the largest medical center in Israel (2007-2019) were reviewed. The primary outcome was all-cause mortality. Cox regression and propensity score matching models were applied. RESULTS: The final cohort included 97,096 patients. Mild, moderate, and severe TR was documented in 27,147 (28%), 2,844 (3%) and 1,805 (2%) patients, respectively. During a median follow-up period of 5 years (interquartile range, 2-8 years), 22,170 patients (23%) died. Kaplan-Meier survival analysis demonstrated an increased risk for death with an increasing degree of TR (log-rank P < .001). Propensity score matching of 1,265 patients with severe TR and matched control subjects showed that compared with those with nonsevere TR, patients with severe TR were 17% more likely to die (95% CI, 1.05-1.29; P = .003). The association of severe TR with survival was dependent on estimated right ventricular (RV) pressure, with a more pronounced effect among patients with estimated systolic pressure ≤ 40 mm Hg (hazard ratio, 2.12 vs 1.04; P for interaction < .001). A landmark subanalysis of 17,967 patients demonstrated that RV function deterioration on follow-up echocardiography modified the association of severe TR with survival. It was more significant among patients with preserved and stable RV function (P for interaction = .035). CONCLUSIONS: The outcome of severe TR is modified by RV pressure and function. Once RV function deteriorates, differences in the outcomes of patients with and without severe TR are less pronounced. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Quality Control of 3-Nitro-4-chlorobenzenesulfonamide

3-Nitro-4-chlorobenzenesulfonamide(cas:97-09-6) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis.
