This manuscript details the impact of stabilizing agents on the structural, optical properties of Ag@SnO2 core shell nanoparticles and its biological applications. Three different stabilizing agent viz. Poly Vinyl Pyrrolidone (PVP), zeroth generation triazolyl glycodendrimer and zeroth generation triazolyl chalcone dendrimer were used as stabilizers in the synthesis of Ag@SnO2 nanoparticles. The results were compared to study their effect on the structural and optical properties of the synthesized samples. The structural parameters of the samples were investigated by XRD analysis, FESEM and HRTEM images. The presence of SnO2 shell on the Ag core was also corroborated by XPS results. The XRD data was used for refining and characterizing the elements present in the sample by Reitveld method. The average crystallite size, dislocation density, lattice parameters (a, c), lattice strain of the samples were calculated using XRD measurements. Williamson – Hall (W-H) method and Size Strain Plot (SSP) method were used to calculate the lattice strain of the synthesized sample. The concentric rings of the SAED pattern and the lattice fringe images exhibited the interplanar d-spacing values and the results were compared with XRD measurements. The optical properties of the samples were investigated using UV-Vis spectra and the band gap energy were calculated using Tauc plot. The Photoluminescence (PL) studies of the Ag@SnO2 core – shell nanoparticles with the three stabilizing agents are also discussed in this work. The antibacterial and antifungal activities of the chalcone dendrimer stabilized Ag@SnO2 core – shell nanoparticles were tested against the pathogens Bacillus subtilis, Proteus mirabilis, Candida albicans and Aspergillus niger.

Synthesis of fifteen C-4-aroyl-C-5-aryl-N-1-(5 ‘-deoxythymidin-5 ‘-yl)-1,2,3-triazoles have been reported starting from azidation of 5 ‘-p-toluenesulfonyloxythymidine followed by azide-alkene oxidative cycloaddition reaction of the resulted 5 ‘-azido-5 ‘-deoxythymidine with 1,3-diarylpropenones in dimethylformamide (DMF) in the presence of tetra-n-butylammonium hydrogen sulfate (n-Bu4N+HSO4-, TBAHS) as catalyst in 60 to 79% overall yields. Further, they were also synthesized by one pot sequential reaction of tosylated thymidine with sodium azide in DMF and then with 1,3-diarylpropenones in presence of n-Bu(4)N(+)HSO(4)(-)in superior yield of 70 to 95% than 60 to 79% in two step procedure. All fifteen synthesized compounds were screened for theirin vitroantiMycobacterium tuberculosisactivity against sensitive reference strain H37Rv and multi drug resistant (MDR) clinical isolate 591, and found to exhibit minimum inhibitory concentration (MIC) ranging from 2 to 15 mu g/mL, which was equivalent to the MIC of first line anti-tubercular drug streptomycin. All compounds qualify for their drug likeness when their physicochemical parameters were assessed using online MolSoft and Lipinski filter software, except their molecular weight. The cytotoxicity of potent compounds evaluated human monocytic cell line THP-1 by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was found to be less as compared to the first line drug, isoniazid.

A palladium(II)-catalyzed 1,1-difunctionalization of unactivated terminal and internal alkenes via addition of two nucleophiles was developed using a cationic palladium(II) complex. The palladacycle generated in situ as a result of a regioselective addition of a nucleophile to the alkene can readily undergo regioselective beta-hydride elimination and migratory insertion with a cationic palladium catalyst. The resulting eta(3)-pi-allyl palladium(II) complex is the key intermediate that reacts with a second nucleophile to furnish the desired 1,1-difunctionalization of the alkene. Under the optimized reaction conditions, a wide range of indoles and anilines add to alkene units of 3-butenoic or 4-pentenoic acid derivatives to afford the synthetically useful gamma,gamma- or delta,delta-difunctionalized products with excellent regiocontrol. Furthermore, by employing internal hydroxyl or acid groups and external carbon nucleophiles, this transformation enables unsymmetric 1,1-difunctionalization to forge challenging and important oxo quaternary carbon centers. Combining experiments and DFT calculations on the mechanism of the reaction is investigated in detail.

Carbonyl-olefin metathesis and carbonyl-alkyne metathesis represent established reactivity modes between carbonyls, alkenes, and alkynes under Lewis and Bronsted acid catalysis. Recently, an interrupted carbonyl-olefin metathesis reaction has been reported that results in tetrahydrofluorenes via a distinct fragmentation of the reactive intermediate. We herein report the development of an analogous transformation interrupting the carbonyl-alkyne metathesis reaction path resulting in dihydrofluorene products relying on Lewis acidic superelectrophiles as active catalytic species.

Hsp90, as a key molecular chaperone, plays an important role in modulating the activity of many cell signaling proteins and is an attractive target for anticancer therapeutics. Herein, we report the discovery of N-pyridoyl-Delta(2)-pyrazoline analogs as novel Hsp90 inhibitors by integrated approaches of drug design, organic synthesis, cell biology, and qualitative proteomic analysis. Novel chemical compounds were designed and optimized in the adenosine triphosphate-binding site of Hsp90; lead optimized compounds were found to have significant interactions with Asp93 and other amino acids crucial for Hsp90 inhibition. The designed compounds were synthesized by a two-step procedure; different aromatic aldehydes were reacted with various acetophenones to form substituted 1,3-diphenyl-prop-2-enones (Ic-Io), which upon reaction with isonicotinic acid hydrazide in the presence of glacial acetic acid form N-pyridoyl-Delta(2)-pyrazoline compounds (PY1-PY13). Compounds PY3, PY2, and PY1 were identified as potential leads amongst the series, with promising anticancer activity against human breast cancer and melanoma cells, and the ability to inhibit Hsp90 similar to radicicol by drug-affinity responsive target stability proteomic analysis in a whole-cell assay.

The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

Various phytochemicals have been reported to protect against oxidative stress. However, the mechanism underlying has not been systematically evaluated, which limited their application in disease treatment. Nuclear factor erythroid 2 – related factor 2 (Nrf2), a central transcription factor in oxidative stress response related to numerous diseases, is activated after dissociating from the cytoskeleton – anchored Kelch – like ECH – associated protein 1 (Keap1). The Keap1-Nrf2 protein-protein interaction has become an important drug target. This study was designed to clarify whether antioxidantive phytochemicals inhibit the Keap1-Nrf2 protein-protein interaction and activate the Nrf2-ARE signaling pathway efficiently. Molecular docking and 3D – QSAR were applied to evaluate the interaction effects between 178 antioxidant phytochemicals and the Nrf2 binding site in Keap1. The Nrf2 activation effect was tested on a H2O2 – induced oxidative – injured cell model. Results showed that the 178 phytochemicals could be divided into high – , medium – , and low – total -score groups depending on their binding affinity with Keap1, and the high total – score group consisted of 24 compounds with abundant oxygen or glycosides. Meanwhile, these compounds could bind with key amino acids in the structure of the Keap1 – Nrf2 interface. Compounds from high – total – score group show effective activation effects on Nrf2. In conclusion, phytochemicals showed high binding affinity with Keapi are promising new Nrf2 activators.
