Frankincense resin (Boswellia serrata), native to arid regions of India, the Middle East, and parts Africa, has been highly valued for its medicinal properties. This study evaluated antimicrobial potential methanolic extracts Boswellia serrata against Staphylococcus aureus, Pseudomonas aeruginosa, Listeria monocytogenes. High-performance thin-layer chromatography (HPTLC) coupled with bioautography identified bioactive zones, while Liquid Chromatography–Mass Spectrometry (LC-MS) quantified...
The substituent and solvent effect on intramolecular charge transfer (ICT) in 5-arylidene-3-methyl-2,4-thiazolidinediones (series 1) 5-arylidene-3-phenyl-2,4-thiazolidinediones 2) was studied by using experimental theoretical methodology. of specific non-specific solvent–solute interactions the UV–vis absorption maxima shifts evaluated Kamlet-Taft Catalán parameter sets. Linear free energy relationships (LFERs) have been applied to 13C NMR data SSP (single parameter) DSP (dual parameters)....
Magnetite (MG) modified cellulose membrane (Cell-MG), obtained by reaction of 3-aminosilane and subsequently with diethylenetriaminepentaacetic acid dianhydride functionalized waste Cell fibers (Cell-NH2 Cell-DTPA, respectively), amino-modified diatomite was used for Azoxystrobin Iprodione removal from water. Cell-MG structurally morphologically characterized using FT-IR FE-SEM techniques. The influences operational parameters, i.e. pH, contact time, temperature, the mass adsorbent on...
The substituent and solvent effects on solvatochromism in 3-[(4-substituted) phenylamino]isobenzofuran-1(3H)-ones were studied using experimental theoretical methodologies. effect of specific non-specific solvent?solute interactions the shifts UV?Vis absorption maxima evaluated Kamlet?Taft Catal?n parameter sets. results by density functional theory (DT) time-dependent (TD-DFT). HOMO/LUMO energies (EHOMO/ELUMO) energy gap (Egap) values, as well mechanism electronic excitations changes...
Unsaturated polyester resins (UPe) were synthesized from maleic anhydride and products of glycolysis, obtained by polyethylene terephthalate (PET) depolymerization with dipropylene glycol (DPG) in the presence tetrabutyl titanate catalyst. Waste PET glycolyzed product UPes characterized FTIR NMR spectroscopy, elemental analysis, acid value (AV), hydroxyl (HV) iodine value. Nanocomposites, based on unsaturated hexamethyldisilazane modified silica nanoparticles, prepared intention to show one...
Synthesis of high-performance alkyd resins (ARs) based on waste poly(ethylene terephthalate) (PET) glycolyzates is presented. PET were synthesized by catalytic depolymerization with trimethylolpropane (TMP) and trimethylolethane (TME) used as replacement polyhydroxylic component during the ARs synthesis. The obtained produced analyzed using FTIR, 1H 13C NMR spectroscopy acid, iodine, hydroxyl value determined. Rheological properties ARs, well as, thickness, adhesion, hardness gloss values...
Barbiturate derivatives were evaluated for their parameters of biological activity by applying linear regression and two multivariate methods (Cluster analysis Principal component analysis). The lipophilicity the studied barbiturates was determined on modified carriers C18 in mixtures water four organic modifiers separately (methanol, n-propanol, acetone tetrahydrofuran) performing reversed phase thin layer chromatography relevant software packages. Chromatographic computational examined...
The optimized methods for N-alkyl and N,N-dialkyl substituted thioureas synthesis starting from ammonium thiocyanates, waste water constituent the production of tetramethylthiuram monosulfide (TMTS), alkyl amine, are presented in this work. Therefore, was developed two ways: Method I - reaction thiocyanate alkylamine presence hydrochloric acid; II with benzoyl chloride following by amine addition first step, base hydrolysis second step. structure synthesized compounds confirmed IR, 1H 13C...
Thanks to the in silico approach drug design, identification of new molecules is enabled and facilitated, as well optimization pharmacokinetics toxicity compounds obtained from different sources. Chromatographic methods, on other hand, provide accurate reliable information influence nature substituents applied organic modifiers pharmacological behavior compounds, relying existence similarities between intermolecular interactions that determine compound biological chromatographic media....
