Green synthesis of antimicrobial and antitumor N,N,N-trimethyl chitosan chloride/poly (acrylic acid)/silver nanocomposites.
The present study is imported to solve two critical problems we face in our daily life which are microbial pollution and colon cancer. One pot green synthesis of a water soluble polyelectrolyte complex (PEC) between cationic polysaccharide as N,N,N-trimethyl chitosan chloride (TMC) and anionic polymer as poly (acrylic acid) (PAA) in presence of silver nanoparticles to yield (TMC/PAA/Ag) nanocom...
متن کاملOn the direct scavenging activity of melatonin towards hydroxyl and a series of peroxyl radicals.
The reactions of melatonin (MLT) with hydroxyl and several peroxyl radicals have been studied using the Density Functional Theory, specifically the M05-2X functional. Five mechanisms of reaction have been considered: radical adduct formation (RAF), Hydrogen atom transfer (HAT), single electron transfer (SET), sequential electron proton transfer (SEPT) and proton coupled electron transfer (PCET)...

15 صفحه اولElectron Paramagnetic Resonance Spectrometry-based Assessment of Free Radicals Scavenging Potential of N-acetyl Tryptophan Glucoside
Gamma radiation generates free radicals in biological system by inducing cellular water radiolysis. If not neutralised, free radicals oxidise vital bio-macromolecules causing structural and functional impairment and contribute to cell death. In present study, free radical scavenging activities of a novel bacterial secondary metabolite, N-acetyl tryptophan glucoside (NATG) was assessed against g...
متن کاملThe gene transfection efficiency of thermoresponsive N,N,N-trimethyl chitosan chloride-g-poly(N-isopropylacrylamide) copolymer.
A thermoresponsive copolymer, trimethyl chitosan-g-poly(N-isopropylacrylamide) (TMC-g-PNIPAAm), was synthesized by coupling PNIPAAm-COOH to TMC. Their molecular structures were characterized by 1HNMR. The lower critical solution temperature (LCST) of TMC-g-PNIPAAm in PBS was measured as 32 degrees C by dynamic light scattering (DLS) and UV-vis spectroscopy, regardless of the grafting ratios. Up...
