摘要：
Methyl 1-(5-methyl isoxazol-3-oxy acetoxy) alkyl methyl phosphinates were synthesized by the condensation of O-methyl methyl 1-hydroxyalkyl phosphinates moiety with 5-methyl isoxazol-3-oxy acetyl chloride and were tested for plant growth regulatory activity and herbicidal activity. Some compounds exhibited notable plant regulatory activity and herbicidal activity.

摘要：
A number of 1-alkyl-1,3,2-diazaphospholidin-4-thione-2-sulfides(2) have been synthesized by the cyclization reaction of Lawesson's reagent with 3- alkyl- glycinamides(1). The bio-assay indicates that some of compounds prepared have good selective herbicidal activity and the quantitative structure- herbicidal activity relationship (QSAR) of compounds(2) has also been studied.

摘要：
Based on a detailed ab initio study on the reaction mechanism of phosphoryl ester exchange and N --> O migration reactions of dimethyloxyphosphoryl-threonine, ab initio GIAO magnetic shielding calculations have been carried out on the predicted stable intermediate and the corresponding reactant and product. The P-31 NNR chemical shift of the most stable penta-coordinate phosphorus intermediate has been predicted as about -71 ppm. The theoretical results may lead to a possible way to experimentally examine our predictions and to monitor the most stable intermediate during the reaction process.

摘要：
A sensitive anodic stripping procedure for trace nitrite in the presence of added cetyltrimethylammonium bromide (CTMAB) is described. The method is based on the electrodeposition and subsequent oxidation of CTMAB-nitrite complex on a glassy carbon electrode in a supporting solution, consisting of Britten-Robinson buffer solution, pH range 3.6-4.0, and CTMAB. The peak height is proportional to the concentration of nitrite over the range 0.01-0.25 μg ml-1, and the relative standard deviation is less than 3.3%. This method has been used for the determination of trace nitrite in water and meat products with 90-110% recovery.

摘要：
Microcalorimetry was used to study the kinetics of action of five kinds of Schiff base on a strain of Aerobacter aerogenes. Differences in their capacities to suppress the metabolism of this bacterium were observed. The extent and duration of the inhibitory effect on the metabolism as judged from the multiplication rate constant, k, varied with the different Schiff bases. The multiplication rate constants, k, of Aerobacter aerogenes (in log phase) in the presence of Co(III)-NG and Ni-NG (NG: D-glucosamine-beta-naphthol aldehyde) decreased with the increasing concentrations of the compounds C, but the relationship between k and C was not of good linearity. For Fe(III)-NG, the multiplication rate constants are constant irrespective of variations in concentration. Similarly over the concentration range 50-200 mu g mL(-1,) there is nearly change in the inhibitory effects of NG on Aerobacter aerogenes, while they are slightly reduced beyond 200 mu g mL(-1). The experimental results revealed that the sequence of antibiotic activity of Schiff base drugs is: Co(III)-NG > Ni-NG > NG > Fe(III)-NG.
