Biological Evaluation of a Secondary Metabolite, 9-O-methylfusarubin, from Fusarium oxysporum
      
9-O-methylfusarubin was isolated from a novel source, Fusarion oxysporum, and evaluated for its phytotoxic and chlorotic inducing properties in plants as well as its potential as an antineoplastic agent.
      
At the 50 μM dose, the number of viable cells was reduced by 65% suggesting potential antineoplastic effects of 9-O-methylfusarubin.
      
Chemo-Enzymatic Synthesis of Hexakis(6-O-allyl)cyclomaltohexaose
      
The amylose 1 was selectively converted into 2 without protection of the other hydroxyl groups by allylation at the all O-6 positions in excess base.
      
Then, the hexakis(6-O-allyl)cyclomaltohexaose 3 was formed from 2 by the thermostable cyclomaltodextrin glucanotransferase (CGTase).
      
A sensitive nicotine sensor based on molecularly imprinted electropolymer of o-aminophenol
      
A sensitive nicotine sensor based on a molecularly imprinted electropolymer of o-aminophenol is proposed and its configuration and performance are studied in detail.
      
On the condition of weak acidity, the sensitive layer was prepared by electropolymerization of o-aminophenol on a gold electrode in the presence of the template (nicotine).
      
Research on multiphase synthesis of 1,5-di(o-anisidino) anthraquinone
      
According to the Ullman reaction mechanism, the synthesis of 1,5-di(o-anisidino)anthraquinone was achieved by the multiphase reaction of 1,5-dichloroanthraquinone in xylene and o-anisidine in the presence of copper metal powder and potassium acetate.
      
X-ray diffraction (XRD) result shows that the Mn2O3 nanotube has a crystalline structure different from o-Mn2O3, t-Mn2O3, h-Mn2O3 and γ-Mn2O3.
      
In this study, H-form oleoyl-carboxymethyl-chitosan (H-O-CMCS) was prepared as a coagulation agent to clean up the residual oil from the waste-water of oil extraction (WWOE).
      
The adsorption capacities of four absorbents (H-O-CMCS, chitosan, activated carbon and polyaluminium chloride (PAC)) for the residual oil were investigated.
      
H-O-H-topology grid was adopted as computation grid, that is, an H-topology grid was adopted for inlet and outlet segment, whereas an O-topology grid was adopted for stator zone and rotor zone.
      
Hydrolysis of crab chitosan was induced by O-glycoside hydrolase (EC 3.2.1), the extracellular chitinolytic complex from Bacillussp.
      
Enzymes hydrolyzing 4-O-methyl-α-D-glucurono-β-D-xylan and sodium carboxymethyl xylan were also found in the culture liquid after 4 h of fungal growth.
      
Pretreatment of plant seeds with kartolin-4 (o-isopropyl-N-2-hydroxyethyl carbamate), a preparation with cytokinin activity, reduced the dehydration-induced inhibition of enzymatic activity.
      
Inhibition of 3,3",5,5"-Tetramethylbenzidine and o-Phenylenediamine Peroxidation with 1-Amino-2-Naphtol-4-Sulfonic Acid and Its
      
Kinetics of coupled o-phenylenediamine (PhDA) and ANSA or poly(ADSNSA) oxidation was studied in phosphate-citrate buffers at pH 3 to 7.
