Immobilization Of Laccase Onto A Porous Nanocomposite: Application For Textile Dye Degradation
(Scientific Technical Research Council Turkey-Tubitak, 2016)
Poly(MA-alt-MVE)-g-PLA/ODA-MMT nanocomposite was prepared by self-catalytic interlamellar graft copolymerization of L-lactic acid (LA) onto poly(maleic anhydride-alt-methyl vinyl ether) copolymer in the presence of octadecyl ...
Polyphenolic Constituents And Antioxidant Potential Of Geranium Stepporum Davis
(Acg Publications, 2011)
The crude MeOH extract prepared from the aerial parts of G. stepporum and its EtOAc, n-BuOH, H(2)O subextracts were screened for their inhibitory activity on H(2)O(2)-induced lipid peroxidation in human red blood cells. ...
Phenylpropanoids, Sesquiterpenoids And Flavonoids From Pimpinella Tragium Vill. Subsp Lithophila (Schischkin) Tutin
(Acg Publications, 2016)
A new sesquiterpenoid named germacradiene-6-O-(6'-O-acetyl)-beta-D-glucoside (1) and a new flavonol glycoside named rhamnetin-3-O-(2 ''-O-beta-D-glucopyranosyl)-beta-D-galactopyranoside (2), along with three known ...
Phenylethanoid and Iridoid Glycosides from Veronica Persica
(Pharmaceutical Soc Japan, 2002)
A new phenylethanoid glycoside, persicoside (1) and three known phenylethanoid glycosides, acteoside (2), isoacteoside (3) and lavandulifolioside (4) were isolated from the aerial parts of Veronica persica. On the basis ...
Cholinesterase Inhibition And Molecular Docking Studies Of Sesquiterpene Coumarin Ethers From Heptaptera Cilicica
(Acg Publications, 2017)
Five sesquiterpene coumarin ethers: umbelliprenin, umbelliprenin-10', 11'-monoepoxide, conferone, mogoltacin and feselol were isolated from the fruits of Heptaptera cilicica. Their structures were identified by means of ...
A Ruthenium-Based Catalytic System with Switchable Selectivity Between Cyclotrimerization and Enyne Metathesis/Diels-Alder Reactions of Terminal Alkynes
(Elsevier, 2013)
In this study, we report a practical catalytic system, [RuCl2( p-cymene)](2)/IPr (IPr: 1,3-bis(2,6 diisopropylphenyl) imidazol-2-ylidene), that can switch between cyclotrimerization and cross enyne metathesis. The ...
Immobilized Metal Ion Affinity Nanospheres For Alpha-Amylase Immobilization
(Scientific Technical Research Council Turkey-Tubitak, 2014)
Immobilized metal chelate affinity chromatography (IMAC) support was practiced for alpha-amylase immobilization. Poly(hydroxyethylmethacrylate-methacryloylamidotryptophan)-Ni2+ [p(HEMA-MAT)-Ni2+] nanospheres, average ...
Ionizing Radiation: A Versatile Tool for Nanostructuring of Polymers
(Walter De Gruyter Gmbh, 2016)
Very high energies of particulate (accelerated electrons, swift heavy ions) or electromagnetic wave (gamma-, X-rays) radiation can be used to initiate free radical based reactions in solids, liquids or gases. Because of ...
A Rare Gamma-Pyranopyrazole Skeleton: Design, One-Pot Synthesis and Computational Study
(Royal Soc Chemistry, 2016)
Drawing upon a consecutive amide coupling and intramolecular cyclisation pathway, a one-pot, straight-forward synthetic route has been developed for a range of pyrazole fused gamma-pyrone derivatives. The reaction mechanism ...
Facile Synthesis Of Heteroaryl Substituted Gamma-Lactams From Nitrovinyl Arenes
(Scientific Technical Research Council Turkey-Tubitak, 2018)
Aliphatic nitroalkanes with different functional groups were synthesized from the Michael addition reactions of active methylene compounds 2 and nitrovinyl arenes 1 in high yields. The synthesized Michael adducts were ...
