3,7-Dimethylguanine, A New Purine From A Philippine Sponge Zyzzya Fuliginosa
(Pharmaceutical Soc Japan, 2001)
A new purine 3,7-dimethylguanine (1) has been isolated from the marine sponge Zyzzya fuliginosa, along with the known metabolites. makaluvamines A, C, K (2-4), 4-hydroxyphenylacetic acid (5), methyl ester of 4-hydroxyphenylacetic ...
Schiff-Bases and Their Complexes With Metal-Ions .1. 2-Hydroxy-N-N-Propyl-1-Naphthaldimine (1) and Bis(2-Hydroxy-Kappa-O-N-N-Propyl-1-Naphthaldiminato-Kappa-N)Nickel(Ii) (2)
(Munksgaard Int Publ Ltd, 1995)
(1) [systematic name: 1-(2-aza-1-penten-1-yl)-2-naphth-ol], C14H15NO, is a bidentate ligand used for the preparation of (2), [Ni(C14H14NO)(2)]. It has an unexpectedly short C2-O [1.254(8) Angstrom] bond length, and a H ... ...
Sampling of Protein Folding Transitions: Multicanonical Versus Replica Exchange Molecular Dynamics
(Amer Chemical Soc, 2013)
We compare the efficiency of multicanonical and replica exchange molecular dynamics for the sampling of folding/unfolding events in simulations of proteins with end-to-end beta-sheet. In Go-model simulations of the 75-residue ...
Preconcentration and Determination of Lead, Cadmium and Nickel From Water Samples Using a Polyethylene Glycol Dye Immobilized on Poly(Hydroxyethylmethacrylate) Microspheres
(Japan Soc Analytical Chemistry, 2006)
A simple and sensitive preconcentration analysis-atomic absorption spectrometric procedure is described for the determination of lead, cadmium and nickel. The method is based upon on-line preconcentration of metal ions on ...
A Novel Two-Enzyme Amperometric Electrode For Lactose Determination
(Japan Soc Analytical Chemistry, 2002)
Coimmobilization of beta-galactosidase and glucose oxidase in a redox polymer, polyvinylferrocenium perchlorate (PVF+ClO4-), led to the development of an enzyme electrode for the determination of lactose. The amperometric ...
Rapid and Alternative Fabrication Method for Microfluidic Paper Based Analytical Devices
(Elsevier Science Bv, 2016)
A major application of microfluidic paper-based analytical devices (mu PADs) includes the field of point-of-care (POC) diagnostics. It is important for POC diagnostics to possess properties such as ease-of-use and low cost. ...
Aminated Poly(Vinyl Chloride) Solid State Adsorbents with Hydrophobic Function For Post-Combustion CO2 Capture
(Royal Soc Chemistry, 2017)
In this paper, we show a novel sustainable route for the production of sorption materials for carbon capture technologies by utilizing a general plastic waste. By supporting aminated poly( vinyl chloride) on mesoporous ...
Adulteration Determining Of Pharmaceutical Forms Of Ginkgo Biloba Extracts From Different International Manufacturers
(Acg Publications, 2014)
In this study, Ginkgo biloba products used for the same purpose, but licensed to varying authorities were analyzed in point of similarity to each other. A group of these products were licensed from health authorities as ...
(5-Chloro-1,3-Benzoxazol-2-Ylthio)Acetonitrile
(Munksgaard Int Publ Ltd, 1994)
(5-Chloro-1,3-benzoxazol-2-ylthio)acetonitrile, C9H5-ClN2OS, was obtained by the reaction of chloro-acetonitrile with 5-chloro-2-mercaptobenzoxazole. The structure of the title compound was indicated by IR, H-1 NMR and ...
Radical Scavenging Effects of Different Veronica Species
(Acg Publications, 2011)
It is well known that the excessive production of reactive oxygen species is hazardous for living organisms and damages major cellular constituents such as DNA, lipid and protein. To find new products reducing free radical ...
