Richards, Mark L.; Lio, Shirley Cruz; Sinha, Anjana; Banie, Homayon; Thomas, Richard J.; Major, Michael; Tanji, Mark; Sircar, Jagadish C. published the artcile< Substituted 2-phenyl-benzimidazole derivatives: novel compounds that suppress key markers of allergy>, COA of Formula: C8H4ClF3O2, the main research area is phenyl benzimidazole derivative marker allergy.

The pharmacotherapy of allergy and asthma has traditionally focused on the effecter mols. of the allergic cascade, while neglecting targets that play an early role in their development. Reasoning that IgE is central to the expansion of atopic diseases, we identified and extended a novel family of 2-(substituted phenyl)-benzimidazole inhibitors of IgE response. Pharmacol. activity depends on an intact phenylbenzimidazole-bis-amide backbone, and is optimized by the presence of lipophilic terminal groups composed of either bis cycloalkyl or combinations of aliphatic and halogen-substituted aromatic groups. These compounds also inhibit IL-4 and IL-5 responses in T cells and CD23 expression on B cells, with potencies that parallel their inhibition of IgE. The broad profile of these compounds thus underscores their potential for treating the multifarious pathol. of asthma.

Ju, Changha; Park, Chanhyuk; Kim, Taehyung; Kang, Hyo published the artcile< Vertical alignment of liquid crystals on plant-based vanillin derivative-substituted polystyrene films>, Formula: C9H9Cl, the main research area is vanillin polystyrene film liquid crystal thermal optical property.

To investigate the alignment behavior of liquid crystal (LC) mols., we synthesized a series of vanillin derivative-substituted polystyrene films (PVAN#, # = 20, 40, 60, 80, and 100), where # is the substitution ratio (%) of the vanillyl Bu ether (VAN) moiety as one of the bio-renewable vanillin derivatives In general, a vertical LC alignment was observed in the LC cell fabricated using the polymer film having a higher molar content of VAN. Moreover, the surface energies of these polymer films were strongly related to the vertical LC alignment behavior. For example, a uniform vertical alignment was observed when the polar surface energy of the polymer was lower than approx. 2.05 mJ m-2, induced by the nonpolar and long carbon groups in the plant-based vanillin moiety. The LC cell fabricated using PVAN100 had good electrooptical characteristics such as voltage holding ratio and residual direct-current voltage and stable alignment under extreme external conditions.

Li, Zengxing; Ng, Kim Hoong; Xu, Shen; Zhang, Yingzhen; Lei, Yonggang; Huang, Jianying; Lai, Yuekun published the artcile< Facile preparation of tremella-like TiO2/Cd:ZnIn2S4 photoanode with enhanced photo-electro-chemical (PEC) performance for energy and environmental applications>, Recommanded Product: Indium(III) chloride tetrahydrate, the main research area is titanium oxide cadmium zinc indium sulfate nanocomposite photoanode; Photoanode; Photoelectrochemical; TiO(2) nanotubes; ZnIn(2)S(4).

The realization of solar-driven photoelectrochem. (PEC) process lies in the success development of materials with excellent photoelec. properties. Past reports identified TiO2, upon modified with both Cd and ZnIn2S4 (ZIS), exhibits promising PEC performance; however, at the cost of tedious preparation In view of this, our work proposes a facile one-step hydrothermal strategy to deposit both modifiers onto the pre-obtained TiO2 nanotubes (NTs), realizing rose-like TiO2/ZnIn2S4 (TiO2/ZIS) or tremella-like TiO2/Cd:ZnIn2S4 (TiO2/Cd:ZIS) with improved PEC performances. Interestingly, the thickness of ZIS petals, which deposited on top of TiO2 NTs, is pos.-correlated to its Cd-composition, signifying the substitutional doping of Cd into the unit cell of ZIS. This renders robust ionic interactions between the constituents, prompting the enhanced optical properties of TiO2 in conjecture to its reduced impedance. As a result, the recombination rate of photo-elec.-derived carriers was drastically suppressed, with an improved photocurrent d. of 606.2μA cm-2 recorded by TiO2/Cd:ZIS photoanode under solar irradiation Such performance is 80 times and 5.16 times higher than those of bare TiO2 NTs and TiO2/ZIS counterparts. The photoconversion efficiencies in terms of incident photon-to-current conversion efficiency (IPCE) and applied bias photon current efficiency (ABPE) for TiO2/Cd:ZIS were significantly improved too, recorded at 1.12% and 0.38%, resp., under standard evaluation condition. As summary, our work proposes a facile one-step hydrothermal approach that simultaneously-deposit both Cd and ZIS onto TiO2 photoanode for an enhanced PEC performance. This opens up a wider horizon for PEC technol., further unlocking its potential in both energy and environmental applications.

Nitration-peroxidation of alkenes for the synthesis of β-peroxyl nitroalkanes has been developed by using tert-Bu nitrite and tert-Bu hydroperoxide. The method presents a new and selective difunctionalization of alkenes to introduce a nitro group and a peroxyl group across the double bonds of alkenes under mild conditions. A radical reaction pathway is proposed by exptl. and theor. studies. Of note, mixing a metal salt and peroxide can cause an explosion.

Kim, Sou Hyun; Kim, Minwoo; Kwon, Doyoung; Pyo, Jae Sung; Kim, Joo Hyun; Kwak, Jae-Hwan; Jung, Young-Suk published the artcile< N-phenyl cinnamamide derivatives protect hepatocytes against oxidative stress by inducing cellular glutathione synthesis via nuclear factor (erythroid-derived 2)-like 2 activation>, HPLC of Formula: 17082-09-6, the main research area is phenyl cinnamamide preparation antioxidant hepatocyte Nrf2 ARE agonistic activity; N-phenyl cinnamamide; antioxidant response element; glutathione; nuclear factor (erythroid-derived 2)-like 2.

Substituted N-Ph cinnamamide derivatives I (R = OMe, OEt, CN, Cl, N(Me)2) were designed and synthesized to confirm activation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2) pathway by the electronic effect on beta-position of Michael acceptor according to introducing the R1 and R2 group. Compounds were screened using the Nrf2/antioxidant response element (ARE)-driven luciferase reporter assay. Compound II (R = N(Me)2) showed desirable luciferase activity in HepG2 cells without cell toxicity. MRNA and protein expression of Nrf2/ARE target genes such as NAD(P)H quinone oxidoreductase 1, hemeoxygenase-1, and glutamate-cysteine ligase catalytic subunit (GCLC) were upregulated by compound II (R = N(Me)2) in a concentration-dependent manner. Treatment with compound II (R = N(Me)2) resulted in increased endogenous antioxidant glutathione, showing strong correlation with enhanced GCLC expression for synthesis of glutathione. In addition, tert-Bu hydroperoxide (t-BHP)-generated reactive oxygen species were significantly removed by compound II (R = N(Me)2) , and the results of a cell survival assay in a t-BHP-induced oxidative cell injury model showed a cytoprotective effect of compound II (R = N(Me)2) in a concentration dependent manner. In conclusion, the novel compound II (R = N(Me)2) can be utilized as an Nrf2/ARE activator in antioxidative therapy.

Corton, J. Christopher; Witt, Kristine L.; Yauk, Carole L. published the artcile< Identification of p53 Activators in a Human Microarray Compendium>, Reference of 6055-19-2, the main research area is p53 activation human microarray DNA damage.

Biomarkers predictive of mol. and toxicol. effects are needed to interpret emerging high-throughput transcriptomic data streams. The previously characterized 63 gene TGx-DDI biomarker that includes 20 genes known to be regulated by p53 was previously shown to accurately predict DNA damage in chem.-treated cells. The authors comprehensively evaluated whether the mol. basis of the DDI predictions was based on a p53-dependent response. The biomarker was compared to microarray data in a compendium derived from human cells using the Running Fisher test, a nonparametric correlation test. Using the biomarker, the authors identified conditions that led to p53 activation, including exposure to the chem. nutlin-3 which disrupts interactions between p53 and the neg. regulator MDM2 or by knockdown of MDM2. The expression of most of the genes in the biomarker (75%) were found to depend on p53 activation status based on gene behavior after TP53 overexpression or knockdown. The biomarker identified DDI chems. that were strong inducers of p53 in wild-type cells; these p53 responses were decreased or abolished in cells after p53 knockdown by siRNAs. Using the biomarker, the authors screened ∼1950 chems. in ∼9800 human cell line chem. vs. control comparisons and identified ∼100 chems. that caused p53 activation. Among the pos. chems. were many that are known to activate p53 through direct and indirect DNA damaging mechanisms. These results contribute to the evidence that the TGx-DDI biomarker is useful for identifying chems. that cause DDI and activate p53.

Bhansali, Pravin; Hanigan, Christin L.; Casero, Robert A.; Tillekeratne, L. M. Viranga published the artcile< Largazole and analogues with modified metal-binding motifs targeting histone deacetylases: Synthesis and biological evaluation>, Computed Properties of 19995-38-1, the main research area is peptidomimetic largazole enantioselective synthesis antitumor structure activity chelator zinc; cyclopeptide histone deacetylase inhibitor tubulin acetylation colon carcinoma; cyclocondensation enzymic resolution Wittig reaction aldol condensation; conjugate addition acyl transfer coupling Yamaguchi esterification macrolactamization trityl; chiral auxiliary acetyl Nagao transition state structure.

The histone deacetylase inhibitor largazole was synthesized by a convergent approach that involved several efficient and high yielding single pot multistep protocols. Initial attempts using tert-Bu as thiol protecting group proved problematic, and synthesis was accomplished by switching to the trityl protecting group. This synthetic protocol provides a convenient approach to many new largazole analogs. Three side chain analogs with multiple heteroatoms for chelation with Zn2+ were synthesized, and their biol. activities were evaluated. They were less potent than largazole in growth inhibition of HCT116 colon carcinoma cell line and in inducing increases in global H3 acetylation. Largazole and the three side chain analogs had no effect on HDAC6, as indicated by the lack of increased acetylation of α-tubulin.
