The petals, stems, bark, leaves were used the Plant induce reduction Cu2+ ions into CuNP act as protection stabilization agents. formation CuNPs was monitored throughout synthesis process by absorption spectra UV–Vis spectrophotometer. Fourier transfer infrared (FTIR)...
Synthesis and biological activity of some new 1-benzyl 1-benzoyl-3-heterocyclic indole derivatives Starting from 1-benzyl- ( 2a ) 1-benzoyl-3-bromoacetyl indoles 2b heterocyclic, 2-thioxoimidazolidine 4a, b ), imidazolidine-2,4-dione 5a, pyrano(2,3- d )imida-zole 8a, 9a, 2-substituted quinoxaline 11a, b-17a, triazolo(4,3- a )quinoxaline 18a, 19a, were synthesized evaluated for their antimicrobial anticancer activities. Antimicrobial screening performed with concentrations 0.88, 0.44 0.22 μg...
Nanomaterial is a rapidly growing area that used to create variety of new materials and nanotechnology applications from medical, pharmaceuticals, chemical, mechanical, electronics several environmental industries including physical, chemical biological nanoparticles are very important in our daily life. Nanoparticles with leaf extract the healthy plant research using biosynthesis methods. Because it’s as an environmentally ecofriendly, other than traditional physical strategies. In...
A monolithic methacrylate packed 96-tips device was used for the extraction of busulfan and cyclophosphamide in whole blood samples. Using a set, 96-well plate could be handled about 2 min. The key aspect phase is that material can offer both good capacity low-back-pressure properties. validation methodology showed accuracy values quality-control samples were between 99 113% busulfan, 103 110% cyclophosphamide. inter-day precision ranged from 7.0 to 12% 13 16% standard calibration curves...
In recent years, molecular modeling has become an important technique for drug discovery and pharmaceutical science. The objective of this study is to determine the antibacterial, anti-inflammatory anti-nociceptive activities a new series pyrazoles, oxadiazoles sugar hydrazines 5-nitroindolin-2- one derivatives. protocol was applied using MOE (Molecular Operating Environment) software. Synthetic compounds 1, 3, 8, 9, 10 12 were most active compounds, as antiinflammatory studied binding...
Microextraction by packed sorbent (MEPS) was used to handle whole mice blood samples.MEPS as an online rapid sample-preparation method, followed liquid chromatography with tandem mass spectrometry (LC-MS/MS).Cyclophosphamide in a model compound.The new method reduced the handling time and cost could small volumes of samples (20 μL).The lower limit quantification (LLOQ) 0.1μg/mL.The accuracy quality-control (QC) ranged from 107 110 %.The within-day variation within range 2.0-7.0%(C.V.%) while...
