Venetoclax (ABT-199) and idasanutlin (RG7388) are efficient anticancer drugs targeting two essential apoptosis markers, Bcl-2 and MDM2, resp. Recent studies have shown that the combination of these two drugs leads to remarkable enhancement of anticancer efficacy, both in vitro and in vivo. In an attempt to disclose the relationships of their protein targets, competitive affinity-based proteome profiling coupled with bioimaging was employed to characterize their protein targets in the same cancer cell line and tumor tissue. A series of protein hits, including ITPR1, GSR, RER1, PDIA3, Apoa1, and Tnfrsf17 were simultaneously identified by pull-down/LC-MS/MS with the two sets of affinity-based probes. Dual imaging was successfully carried out, with the simultaneous detection of Bcl-2 and MDM2 expression in various cancer cells. This could facilitate the novel diagnostic and therapeutic strategies of dual targeting of Bcl-2/MDM2. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Category: amides-buliding-blocks

On January 31, 2022, Ratanaphain, Chatkrita; Viboonratanasri, Duangkamon; Prompinit, Panida; Krajangpan, Sita; Khan, Eakalak; Punyapalakul, Patiparn published an article.Product Details of 79-07-2 The title of the article was Reactivity characterization of SiO2-coated nano zero-valent iron for iodoacetamide degradation: The effects of SiO2 thickness, and the roles of dehalogenation, hydrolysis and adsorption. And the article contained the following:

The effect of SiO2-layer thickness in SiO2-coated nano zero-valent iron (nZVI) particles on the reactivity characteristics of iodoacetamide (IAcAm) degradation was evaluated. SiO2-layer thicknesses ranging from 3.6 to 27.3 nm were obtained through varying tetra-Et orthosilicate dosages of 0.001-1 M. The crystallinity, surface chem. composition, and physicochem. properties were evaluated for their effects on synergetic degradation mechanisms, dehalogenation, hydrolysis, and adsorption. At a thickness of 3.6 nm, the SiO2 layer offered the highest observed pseudo-first-order rate (kobs) and higher rates of IAcAm degradation were maintained under pH fluctuations (pH 5-7) and aerobic conditions compared to pristine nZVI. At this SiO2-layer thickness (3.6 nm), the rate of iron oxide-layer formation was reduced and the migration of reactive iron species (Fe0 and Fe2+) for the dehalogenation and hydrolysis reactions was enabled. In a single-solute solution, IAcAm elimination was greater than bromoacetamide and chloroacetamide elimination due to the weak ionic I-C bond. In mixed solute conditions, the hydrophobicity of chloroacetamide played a more significant role in competitive degradation through greater adsorption. The proportion of dehalogenation relative to hydrolysis during IAcAm degradation by pristine nZVI and SiO2-coated nZVI was approx. 0.6:0.4. Iodoacetic acid and acetic acid were detected as intermediates in the degradation pathway of IAcAm by pristine nZVI. In contrast, the SiO2 layer on nZVI can accelerate the transformation of IAcAm to acetamide and iodoacetic acid. The electrolyte background of tap water exhibited a slight inhibitory effect on the degradation of IAcAm for both nZVI and SiO2-coated nZVI. The experimental process involved the reaction of 2-Chloroacetamide(cas: 79-07-2).Product Details of 79-07-2

Kakeya, Nobuharu; Yata, Noboru; Kamada, Akira; Aoki, Masaru published an article in 1969, the title of the article was Biological activities of drugs. VII. Structure-activity relations of sulfonamide carbonic anhydrase inhibitors. 2.Application of 97-09-6 And the article contains the following content:

Diuretic, natriuretic activities, and duration of the diuretic action in rats were studied with 22 sulfonamide derivatives To clarify the active form of the sulfonamides, the effect of pH of the rat body fluid on the diuretic activity was studied. The diuretic and natriuretic activities of the sulfonamides increased with an increase in their carbonic anhydrase inhibitory activity except for o-substituted benzenesulfonamides, disubstituted benzenesulfonamides, and 2-amino-1,3,4-thiadiazole-5-sulfonamide. A close relation between diuretic and natriuretic activities with the electronic characteristics of the sulfamoyl group, such as Hammett’s σ constant, pKa, NMR chem. shift of the sulfamoyl protons, and S:O valence-force constant was observed for the derivatives with some exceptions. A compound having a large partition coefficient and strong albumin binding ability showed long duration of the diuretic action. The diuretic and natriuretic activities of sulfonamides were enhanced by an increase in their dissociation constants The diuretic activity was enhanced under alkaline conditions. It was concluded that the active form of the sulfonamide carbonic anhydrase inhibitors was the ionized form. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Application of 97-09-6

On August 31, 2021, Liu, Yanhua; Chen, Yu; Feng, Mengjuan; Chen, Jianqiu; Shen, Weitao; Zhang, Shenghu published an article.Quality Control of N-((4-Aminophenyl)sulfonyl)acetamide The title of the article was Occurrence of antibiotics and antibiotic resistance genes and their correlations in river-type drinking water source, China. And the article contained the following:

The occurrence and distribution of antibiotics and antibiotic resistance genes (ARGs) in natural water has attracted worldwide attention. Antibiotic and ARG pollution in the surface water of drinking water sources might directly/indirectly affect human health. In this study, the distribution of 38 antibiotics, 10 ARGs, 2 integrons, and 16S r DNA in river-type water sources in a large city of China were monitored in winter, which was a period with high level of antibiotic pollution. The results showed that 20 antibiotics were detected with different detection frequencies. The antibiotic pollution in Dec. 2019 was relatively high, with the total concentrations of antibiotics ranging from 281.95 to 472.42 ng/L, followed by that in Jan. 2020 (191.70-337.29 ng/L) and Nov. 2019 (161.25-309.72 ng/L). Sulfacetamide was dominant in Nov. 2019 (23.52-219.00 ng/L) and in Jan. 2020 (113.18-209 ng/L), while norfloxacin in Dec. 2019 (146.72-290.20 ng/L). All the target antibiotics posed low or medium risk for aquatic organisms, and posed low health risk for mankind. Sul1 and erm36 were the predominant ARGs, and intI1 was the predominant integron in drinking water sources. Only tetA showed pos. correlations with its corresponding antibiotic (tetracycline). The rest of ARGs showed no correlations with antibiotics or pos. / neg. correlations with their non-corresponding antibiotics. Overall, the antibiotics and ARG pollution in these water sources was relatively low. These findings provided some reference data for the distribution of antibiotics and ARGs in river-type drinking water sources of large cities in China.

Wan, Yameng; Wu, Hao; Ma, Nana; Zhao, Jie; Zhang, Zhiguo; Gao, Wenjing; Zhang, Guisheng published an article in 2021, the title of the article was De novo design and synthesis of dipyridopurinone derivatives as visible-light photocatalysts in productive guanylation reactions.Related Products of 102-07-8 And the article contains the following content:

De novo design and synthesis of a series of 6H-dipyrido[1,2-e:2′,1′-i]purin-6-ones (DPs), e.g., I as a new class of visible-light photoredox catalysts (PCs) was described. The synthesized DPs showed their λAbs(max) values in 433-477 nm, excited state redox potentials E*1/2 red and E*1/2 ox in 1.15-0.69 eV and -1.41 to -1.77 eV (vs. SCE), resp. As a representative, DP I enabled productive guanylation of amines, including 1°, 2°, and 3°-alkyl primary amines, secondary amines, aryl and heteroaryl amines, amino-nitrile, amino acids and peptides as well as propynylamines and α-amino esters giving diversities in biol. important guanidines and cyclic guanidines. The photocatalytic efficacy of DP I in guanylation overmatched commonly used Ir and Ru polypyridyl complexes, and some organic PCs. Other salient merits of this method included broad substrate scope and functional group tolerance, gram-scale synthesis, and versatile late-stage derivatizations that led to a derivative 81 exhibiting 60-fold better anticancer activity against Ramos cells with IC50 of 0.086μM than that of clin. drug ibrutinib (5.1μM).

On February 28, 2022, Chatterjee, Nabanita; Oliver, Clive L. published an article.Product Details of 685-91-6 The title of the article was Ligated Solvent Influence on Interpenetration and Carbon Dioxide and Water Sorption Hysteresis in a System of 2D Isoreticular MOFs. And the article contained the following:

Four two-dimensional (2D), fluorinated metal-organic frameworks (MOFs), [Cu(hfipbb)(DMF)]n·0.5(DMF)n (1), [Cu(hfipbb)(DEF)]n (2), [Cu3(hfipbb)3(DMA)3]n·6(DMA)n·2(H2O)n (3), and [Cu2(hfipbb)2(DEA)2]n·2(DEA)n·2(H2O)n (4), were synthesized where hfipbb = 4,4′-(hexafluoroisopropylidene)bis(benzoate), DMF = N,N’-DMF, DEF = N,N’-diethylformamide, DMA = N,N’-dimethylacetamide, and DEA = N,N’-diethylacetamide. The choice of a formamide or acetamide solvent ligand leads to 2-dimensional, doubly interpenetrated (1,2) or noninterpenetrated (3,4) MOF structures. Despite their lower potential void spaces, the doubly interpenetrated structures have superior CO2 and hydrogen sorption properties. Their 195 K CO2 sorption isotherms display inflection points, followed by 3̃-fold increases in sorption capacities and very large hysteretic behavior. Small changes in the identity of the ligated solvent ligand can affect whether the resulting MOF is interpenetrated or noninterpenetrated and so drastically affect the sorption properties. The activated phase of a 5th MOF, synthesized through DMF ligand exchange with H2O in 1 (1W), does not display an inflection point and subsequent increased CO2 sorption at 195 K, despite having the same degree of interpenetration, showing that even more subtle differences in the desolvated phases can lead to marked differences in their sorption behavior.

And the article contained the following:

A simple and effective pretreatment method based on matrix solid-phase dispersion was developed for the determination of pharmaceutical and personal care products (PPCPs) and their metabolites in fish by high-performance liquid chromatog. tandem mass spectrometry. The type and amount of dispersant, adsorbent, and eluting solvent were optimized by a single-factor experiment and Box-Behnken design. Under the optimal conditions with 2.5 g of Florisil as a dispersant, 500 mg of C18 as an adsorbent, and 5 mL of acetonitrile as an eluting solvent, the recoveries ranged from 70.4 to 99.9% with relative standard deviations less than 10.5%, and the limits of quantitation ranged from 0.13 to 1.01μg/kg. The developed method was successfully applied to detect PPCPs in marketed fish, and five PPCPs, including triclocarban, sulfadiazine, sulfadimidine, sulfamethoxazole, and carbamazepine, were detected at trace levels. The proposed method, which has the advantages of short anal. time, less solvent consumption, and high sensitivity, can be used for the determination of trace PPCPs in fish.

Boyle, Elizabeth Barksdale; Viet, Susan M.; Wright, David J.; Merrill, Lori S.; Alwis, K. Udeni; Blount, Benjamin C.; Mortensen, Mary E.; Moye, John Jr.; Dellarco, Michael published an article in 2016, the title of the article was Assessment of exposure to VOCs among pregnant women in the National Children’s study.Computed Properties of 27115-50-0 And the article contains the following content:

Epidemiol. studies can measure exposure to volatile organic compounds (VOCs) using environmental samples, biomarkers, questionnaires, or observations. These different exposure assessment approaches each have advantages and disadvantages; thus, evaluating relationships is an important consideration. In the National Children’s Vanguard Study from 2009 to 2010, participants completed questionnaires and data collectors observed VOC exposure sources and collected urine samples from 488 third trimester pregnant women at in-person study visits. From urine, we simultaneously quantified 28 VOC metabolites of exposure to acrolein, acrylamide, acrylonitrile, benzene, 1-bromopropane, 1,3-butadiene, carbon disulfide, crotonaldehyde, cyanide, N,N-dimethylformamide, ethylbenzene, ethylene oxide, propylene oxide, styrene, tetrachloroethylene, toluene, trichloroethylene, vinyl chloride, and xylene exposures using ultra high performance liquid chromatog. coupled with an electrospray ionization tandem mass spectrometry (UPLC-ESI/MSMS) method. Urinary thiocyanate was measured using an ion chromatog. coupled with an electrospray ionization tandem mass spectrometry method (IC-ESI/MSMS). We modeled the relationship between urinary VOC metabolite concentrations and sources of VOC exposure. Sources of exposure were assessed by participant report via questionnaire (use of air fresheners, aerosols, paint or varnish, organic solvents, and passive/active smoking) and by observations by a trained data collector (presence of scented products in homes). We found several significant (p < 0.01) relationships between the urinary metabolites of VOCs and sources of VOC exposure. Smoking was pos. associated with metabolites of the tobacco constituents acrolein, acrylamide, acrylonitrile, 1,3-butadiene, crotonaldehyde, cyanide, ethylene oxide, N,N-dimethylformamide, propylene oxide, styrene, and xylene. Study location was neg. associated with the toluene metabolite N-acetyl-S-(benzyl)-L-cysteine (BMA), and paint use was pos. associated with the xylene metabolites 2-methylhippuric acid (2MHA) and 3-Methylhippuric acid & 4-methylhippuric acid (3MHA + 4MHA). A near-significant (p = 0.06) relationship was observed between acrylamide metabolites and observation of incense. The experimental process involved the reaction of 2-(4-Methylbenzamido)acetic acid(cas: 27115-50-0).Computed Properties of 27115-50-0
