Schutte, RJ; Zhang, XJ; An, N; Ostrov, DA; Vukmanovic, S in [Schutte, Ryan J.; Zhang, Xiaojuan; Ostrov, David A.] Univ Florida, Coll Med, Dept Pathol Immunol & Lab Med, Gainesville, FL 32611 USA; [An, Nan; Vukmanovic, Stanislav] US FDA, Div Cosmet, Off Cosmet & Colors, CFSAN, College Pk, MD USA published Molecular docking predictions of fragrance binding to human leukocyte antigen molecules in 2019.0, Cited 40.0. The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

Background: Over 4000 small chemicals have been identified as allergens capable of inducing skin sensitization. Many sensitizers are hypothesized to act as haptens producing novel antigens, which can be presented to T cells by human leukocyte antigens (HLAs). Recent studies suggest that some chemical allergens use hapten-independent mechanisms. Objective: To determine whether molecular docking can identify HLA molecules that bind skin-sensitizing chemical allergens. Methods: Structural models of HLA molecules were used as the basis for molecular docking of 22 chemical allergens. Allergens predicted to bind HLA-B*57:01 were tested for their ability to stimulate T cells by the use of proliferation and interferon-gamma enzyme-linked immunospot assays. Results: Chemical allergens that did not satisfy the criteria for hapten activity in vitro were predicted to bind more strongly to common HLA isoforms than those with known hapten activity. HLA-B* 57: 01, which is an HLA allele required for drug hypersensitivity reactions, was predicted to bind several allergens, including benzyl benzoate, benzyl cinnamate, and benzyl salicylate. In in vitro T cell stimulation assays, benzyl salicylate and benzyl cinnamate were found to stimulate T cell responses from HLA-B* 57:01 carriers. Conclusions: These data suggest that small-molecule skin sensitizers have the potential to interact with HLA, and show that T cell-based in vitro assays may be used to evaluate the immunogenicity of skin-sensitizing chemicals.

Computed Properties of C7H8O. The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6

The modification of pillared MFI zeolites was performed by nitridation of silica pillared MFI zeolite nanosheets under NH3 atmosphere with different time. The resultant zeolites were characterized by a complementary combination of X-ray power diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), pyridine-IR spectroscopy and N-2 adsorption-desorption isotherms. The analyses showed that the nitridation didn’t destroy the crystallinity and specific surface area of zeolites, and the acidity of zeolites can be tailored by tuning the time of nitridation, resulting in the different concentration ratios of Bronsted-to-Lewis (B/L) acid sites. Moreover, the nitrided zeolites exhibited high selectivity to 2-benzyl-1,3,5-trimethylbenzene than parent silica pillared MFI zeolite nanosheets in benzylation of mesitylene with benzyl alcohol. A balance between Bronsted acid sites and Lewis acid sites can inhibit the self-etherification of benzyl alcohol and enhance the selectivity of alkylated product. These experimental data implied that nitridation was an effective method to modulate the acidity of zeolites and the synergy between Bronsted acid sites and Lewis acid sites was a decisive factor to determine the selectivity.

The present study reports the synthesis of new purine bioisosteres comprising a pyrazolo[3,4-d]pyrimidine scaffold linked to mono-, di-, and trimethoxy benzylidene moieties through hydrazine linkages. First, in silico docking experiments of the synthesized compounds against Bax, Bcl-2, Caspase-3, Ki67, p21, and p53 were performed in a trial to rationalize the observed cytotoxic activity for the tested compounds. The anticancer activity of these compounds was evaluated in vitro against Caco-2, A549, HT1080, and Hela cell lines. Results revealed that two (5 and 7) of the three synthesized compounds (5, 6, and 7) showed high cytotoxic activity against all tested cell lines with IC50 values in the micro molar concentration. Our in vitro results show that there is no significant apoptotic effect for the treatment with the experimental compounds on the viability of cells against A549 cells. Ki67 expression was found to decrease significantly following the treatment of cells with the most promising candidate: drug 7. The overall results indicate that these pyrazolopyrimidine derivatives possess anticancer activity at varying doses. The suggested mechanism of action involves the inhibition of the proliferation of cancer cells.

A total of fourteen pyrazoline derivatives were synthesized through cyclo-condensation reactions by chalcone derivatives with different types of semicarbazide. These compounds were characterized by IR, 1D-NMR (H-1, C-13 and Distortionless Enhancement by Polarization Transfer – DEPT-135) and 2D-NMR (COSY, HSQC and HMBC) as well as mass spectroscopy analysis (HRMS). The synthesized compounds were tested for their antituberculosis activity against Mycobacterium tuberculosis H37Ra in vitro. Based on this activity, compound 4a showed the most potent inhibitory activity, with a minimum inhibitory concentration (MIC) value of 17 mu M. In addition, six other synthesized compounds, 5a and 5c-5g, exhibited moderate activity, with MIC ranges between 60 mu M to 140 mu M. Compound 4a showed good bactericidal activity with a minimum bactericidal concentration (MBC) value of 34 mu M against Mycobacterium tuberculosis H37Ra. Molecular docking studies for compound 4a on alpha-sterol demethylase was done to understand and explore ligand-receptor interactions, and to hypothesize potential refinements for the compound.

Curcumin (CUR) is a symmetrical dicarbonyl compound with antibacterial activity. On the other hand, pharmacokinetic and chemical stability limitations hinder its therapeutic application. Monocarbonyl analogs of curcumin (MACs) have been shown to overcome these barriers. We synthesized and investigated the antibacterial activity of a series of unsymmetrical MACs derived from acetone against Mycobacterium tuberculosis and Gram-negative and Gram-positive species. Phenolic MACs 4, 6 and 8 showed a broad spectrum and potent activity, mainly against M. tuberculosis, Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MRSA), with MIC (minimum inhibitory concentration) values ranging from 0.9 to 15.6 mu g/mL. The investigation regarding toxicity on human lung cells (MRC-5 and A549 lines) revealed MAC 4 was more selective than MACs 6 and 8, with SI (selectivity index) values ranging from 5.4 to 15.6. In addition, MAC 4 did not demonstrate genotoxic effects on A549 cells and it was more stable than CUR in phosphate buffer (pH 7.4) for 24 h at 37 degrees C. Fluorescence and phase contrast microscopies indicated that MAC 4 has the ability to disrupt the divisome of Bacillus subtilis without damaging its cytoplasmic membrane. However, biochemical investigations demonstrated that MAC 4 did not affect the GTPase activity of B. subtilis FtsZ, which is the main constituent of the bacterial divisome. These results corroborated that MAC 4 is a promising antitubercular and antibacterial agent.

Weakly coordinating, ketone-directed C-H vinylation using vinyl acetate is reported here for a wide range of aromatic ketones such as acetophenones, diaryl ketones, chromones and biologically relevant chalcones under cost-effective and air-stable cobalt(iii)-catalysis. Regioselective, mono-vinylation occurs for challenging vinyl substitution-free styrenes in moderate to good yields, and this moiety has been used to synthesize functionalized indanone, alpha-naphthol and an advanced intermediate for bruguierol A synthesis. An acrylate-surrogate provided the corresponding alkenylated product under these vinylation conditions. Detailed mechanistic studies are carried out to support the proposed catalytic cycle.

( )Curcumin (bis-alpha,beta-unsaturated beta-diketone) is a low molecular weight hydrophobic polyphenol isolated from Curcuma longa. Curcumin has attracted significant recent consideration due to its medicinal and pharmacological properties. In this research pyrano[2,3-d]pyrimidine-2,4(3H)-dione derivatives were prepared in excellent yields and short reaction times by a one-pot multi-component cyclocondensation of curcumin, substituted aromatic aldehydes and barbituric acid in the presence of CoFe2O4@OCMC@Cu(BDC) nanostructure as an effective and robust catalyst. The CoFe2O4 functionalized OCMC@Cu(BDC) is introduced as a new, strong and efficient catalyst for the synthesis of a variety of heterocyclic compounds. The catalyst was perfectly characterized by various spectroscopy methods such as Fouriertransform infrared spectroscopy (FT-IR), Energy-dispersive X-ray (EDX), Scanning electron microscope (SEM), X-ray diffraction (XRD) and N2 adsorption-desorption isotherm (BET). Furthermore, the heterocyclic compounds were fully characterized by different spectral techniques including FT-IR, (HNMR)-H-1, (CNMR)-C-13. The magnetic catalyst could be easily recycled and reused for seven runs with a slightly decrease in its activity. (C) 2019 Elsevier B.V. All rights reserved.
