Leung, Euphemia published the artcileThe cytotoxic potential of cationic triangulenes against tumor cells, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is cytotoxic potential cationic triangulene tumor cell.

TOTA (trioxatriangulenium ion) is a close-shelled carbocation known to intercalate strongly with the DNA double helix. The cytotoxicity of TOTA and its four close structural analogs, ADOTA, Pr-ADOTA, Pr-DAOTA and n-Butyl-TATA were tested against the breast cancer cell line MDA-MB-231 and colon cancer cell line HCT116. The most potent derivatives Pr-ADOTA and Pr-DAOTA had IC50 values of ∼80 nM for MDA-MB-231 but slightly higher for HCT116 in the low hundreds nM range. A 3D model assay of HCT116 spheroids was also used, mimicking a tumor environment, again both Pr-ADOTA and Pr-DAOTA were very active with IC50 values of 38 nM and 21 nM, resp. Mol. modeling suggest that the planar derivatives intercalate between the base pairs of the DNA double helix. However, only modest DNA double stranded DNA cleavage was observed using the γH2AX assay as compared to camptothecin, a topoisomerase I poison suggesting a different mechanism. Finally, a robust d. functional theory (DFT) model was built to predict the pKR+ stability values, i.e., to design derivatives, which predominantly have a non-intercalating buckled form in healthy tissues followed by a nucleophilic attach of water on the central carbon, but a planar form at relatively low pH values rendering them only cytotoxic in the interior of tumors.

Pioli, Renan Moraes published the artcileComparison of the effect of N-methyl and N-aryl groups on the hydrolytic stability and electronic properties of betalain dyes, SDS of cas: 5961-59-1, the main research area is betalain dye synthesis hydrolytic stability electronic property methyl acryl.

Betalains are antioxidant secondary metabolites that emerged as safe color additives for food and cosmetics, fluorescent dyes, and redox mediators. Herein, we describe the semisynthesis of N-Me phenylbetalain (mepBeets) and N-aryl phenylbetalain (dipBeets) dyes and compare the effect of the structure on their hydrolytic stability and electronic properties. Eight model compounds were semisynthesized by coupling betalamic acid with either N-Me anilines or N-aryl anilines in Et acetate using p-toluenesulfonic acid as catalyst. The presence of electron-withdrawing substituents in the aryl moiety of mepBeets and dipBeets results in faster hydrolysis, lower anodic potentials and increased fluorescence quantum yields compared to the corresponding unsubstituted parent compounds The results are rationalized by considering the charge distribution in the 1,7-diazaheptamethinium chromophore and are useful for the development of new hydrolytically stable betalain dyes with tunable redox and optical properties.

Sun, Yongnan published the artcileLigand-protected Au4Ru2 and Au5Ru2 nanoclusters: distinct structures and implications for site-cooperation catalysis, Product Details of C8H11NO, the main research area is phenylmercaptan gold ruthenium nanocluster preparation crystal mol structure catalyst; methylation methylaniline phenethylmercaptan gold ruthenium nanocluster catalyzed; methylformanili preparation.

Authors report two ligand-protected Au4Ru2 and Au5Ru2 nanoclusters with distinct at.-packing modes and electronic structures, both of which act as ideal model catalysts for identifying the catalytically active sites of catalysts on the nanoclusters. Au5Ru2 exhibits superior catalytic performances to Au4Ru2 for N-methylation of N-methylaniline to N-methylformanili, which is likely due to the site-cooperation catalysis of Au5Ru2.

Gonzalez-Lainez, Miguel published the artcileEffective N-methylation of nitroarenes with methanol catalyzed by a functionalized NHC-based iridium catalyst: a green approach to N-methyl amines, HPLC of Formula: 5961-59-1, the main research area is effective methylation nitroarene methanol catalyzed functionalized iridium catalyst.

Compound [IrBr(CO)2(κC-tBuImCH2PyCH2OMe)] featuring a flexible pyridine/OMe functionalized NHC ligand κ1C coordinated efficiently catalyzes the selective N-monomethylation of nitroarenes using methanol as both the reducing agent and the C1 source. A range of functionalized nitroarenes including heterocyclic or sterically hindered derivatives have been efficiently converted to the corresponding N-monomethyl amines in good yields at low catalyst loadings using sub-stoichiometric amounts of Cs2CO3 as a base. Mechanistic investigations support a borrowing-hydrogen mechanism in which methanol acts as the hydrogen source and methylating agent. Further, the hydrogen transfer reduction of nitrobenzene to aniline under optimized reaction conditions should proceed through a direct mechanism involving nitrosobenzene and N-phenylhydroxylamine intermediates.

Shi, Yajuan published the artcileNorm index for predicting the rate constants of organic contaminants oxygenated with sulfate radical, Synthetic Route of 151-10-0, the main research area is surface water sulfate radical organic contaminant oxygenation rate modeling; Norm index; Organic contaminants; QSPR; Second-order rate constants; Sulfate radical.

The degradation of organic contaminants in aquatic systems has raised immense attention worldwide, and the second-order rate constant (kSO.-4) of water pollutants oxidized by sulfate radical anion is an important index for assessing the degradation efficiency of organics Herein, a new norm math. formula is defined. Based on this, four new descriptors are proposed and a QSPR model is developed for predicting kSO.-4 using 30 families of emerging organic pollutants in water. The statistical results fully prove that this model has good fitting effect and stability with R2 of 0.8862, Q2LOO of 0.8466, and Q25-fold of 0.8329, resp. The validation results including cross validation, applicability domain anal., and model comparison show that this model has good robustness, predictive performance, and reliability. These decent results indicate that the new norm math. formula is effective in calculating descriptors and the norm indexes have a great application for evaluating the transformation fate of organic pollutants by sulfate radical in aquatic systems.

Ullah, Sultan published the artcileThe tyrosinase-inhibitory effects of 2-phenyl-1,4-naphthoquinone analogs: importance of the (E)-β-phenyl-α,β-unsaturated carbonyl scaffold of an endomethylene type, Related Products of isoquinoline, the main research area is phenylnaphthoquinone endomethylene synthesis tyrosinase skin whitening melanogenesis.

In order to investigate the effect of the (E)-β-phenyl-α,β-unsaturated carbonyl scaffold of an endomethylene type on tyrosinase inhibition, 2-phenyl-1,4-naphthoquinone derivatives were synthesized by Michael addition of substituted benzenes to 1,4-naphthoquinone and subsequently an auto-oxidation Most of the derivatives potently inhibited mushroom tyrosinase and four derivatives, including 1c (IC50 = 22.00 ± 1.63 μM), more potently inhibited mushroom tyrosinase than kojic acid (IC50 = 37.86 ± 2.21 μM). Cell-based assays using B16F10 cells (a melanoma cell line) showed 1c dose-dependently suppressed melanin production and more potently inhibited tyrosinase activity than kojic acid. Docking simulation results between 1c and tyrosinase and a kinetic study suggest that 1c is a competitive inhibitor that binds to the active site of tyrosinase. These results support that anti-melanogenic effect of naphthoquinone derivatives results from their tyrosinase inhibiting activity and the (E)-β-phenyl-α,β-unsaturated carbonyl scaffold of an endomethylene type can confer tyrosinase-inhibitory activity.

Jørgsholm, Peter published the artcileEpidemiology of scaphoid fractures and non-unions: A systematic review., Category: isoquinoline, the main research area is .

BACKGROUND: The scaphoid is the most commonly fractured carpal bone in adults as well as in children. Previous studies have reported a wide range of fracture incidences. Scaphoid fractures and non-unions in children have been sparsely investigated. AIM: To perform a systematic review of the current literature on epidemiology of scaphoid fractures and non-unions in adults and children. METHODS: An electronic literature search was conducted investigating all studies in the literature published between January 1989 and June 23 2020. The systematic review following the PRISMA guidelines and searching in PubMed, Embase, Web of Science and Cochrane library databases was done in June 2020. RESULTS: 42 studies met our inclusion criteria, 6 studies were prospective, 32 were retrospective and 4 were register studies. The majority of studies relied on conventional radiographs for diagnosis. Scaphoid fractures in adults are predominately found in males with a peak incidence in the age group from 20 to 29 years. Incidence rates in males are reported from 107 to 151/100â€?00. Females have an earlier peak, in the age group 10 to 19 years, with an incidence from 14 to 46/100â€?00. Most fractures occur in the middle third of the scaphoid representing 60-69â€? of cases. Scaphoid fractures in children are predominately found in boys age 12 and above, while it seldomly occur for children younger than 9 years. In adults the risk for developing a scaphoid non-union is between 2â€? and 5â€?, the majority affecting males and predominately located at the middle third of the scaphoid. Non-unions among children are rare and mainly due to missed or delayed diagnosis of a fracture in the middle third of the scaphoid. CONCLUSION: This review revealed a substantial heterogeneity among studies concerning study population, diagnosis criterial and outcome measures. Currently, evidence on epidemiology for scaphoid fractures and non-unions are low.

Fritsch, Carolina G published the artcileFamily-based Interventions Benefit Individuals With Musculoskeletal Pain in the Short-term but not in the Long-Term: A Systematic Review and Meta-Analysis., COA of Formula: C8H10O2, the main research area is .

INTRODUCTION: The benefits of family-based interventions for patients with musculoskeletal pain have been previously shown in individual randomized controlled trials (RCTs), but no systematic review has summarized their effects. MATERIALS AND METHODS: A systematic review was conducted to assess the effectiveness of family-based interventions on clinical and biopsychosocial outcomes in people with musculoskeletal pain (PROSPERO CRD42018118442). Meta-analyses were performed for the outcomes of pain intensity, disability, mood, self-efficacy, and marital adjustment. RESULTS: Of 1223 records identified, 18 reports representing 15 RCTs were included in the qualitative review and 10 in the meta-analyses. Family-based interventions were more effective to reduce pain (mean difference [MD], -3.55/100; 95% confidence intreval [CI], -4.03 to -3.06) and disability (MD, -1.51/100; 95% CI, -1.98 to -1.05) than individual-focused interventions at short-term, but not at mid term or long term. There were no effects on other outcomes. Family-based interventions were more effective to reduce pain (MD, -6.05/100; 95% CI, -6.78 to -5.33) compared with usual care only at short-term. No effects were found on disability and other outcomes. DISCUSSION: There is moderate-quality evidence that family-based interventions result in small, significantly better pain and disability outcomes in the short-term compared with individual-focused interventions in patients with musculoskeletal pain. Based on low-quality evidence, family-based interventions result in small improvements on pain in the short-term compared with usual care. Future studies should review the content and optimize the mechanisms underpinning family-based interventions in musculoskeletal pain so that the approach could be further tested in adequately powered RCTs.
