Identification of small molecules blocking the pseudomonas aeruginosa type iii secretion system protein pcrv
Pseudomonas aeruginosa is an opportunistic bacterial pathogen that employs its type III secretion system (T3SS) during the acute phase of infection to translocate cytotoxins into the host cell cytoplasm to evade the immune system. The PcrV protein is located at the tip of the T3SS, facilitates the integration of pore-forming proteins into the eukaryotic cell membrane, and is required for translocation of cytotoxins into the host cell. In this study, we used surface plasmon resonance screening to identify small molecule binders of PcrV. A follow-up structure-activity relationship analysis resulted in PcrV binders that protect macrophages in a P. aeruginosa cell-based infection assay. Treatment of P. aeruginosa infections is challenging due to acquired, intrinsic, and adaptive resistance in addition to a broad arsenal of virulence systems such as the T3SS. Virulence blocking molecules targeting PcrV constitute valuable starting points for development of next generation antibacterials to treat infections caused by P. aeruginosa.

A method for preparing chloro-benzene oxygen carboxylic acid (by machine translation)
The invention provides a method for preparing carboxylic acid chloro-benzene oxygen, comprising the following steps: S1) phenoxy fatty alcohol in the catalyst B A and under the action of the catalyst, and the chlorinating agent to 2 bit and/or 4 bit selective chlorination reaction, to obtain chloro-benzene oxygen fatty alcohol; said catalyst A is Lewis acid; said catalyst B is C5 - 22 of the thioether, thiazole, isothiazole, thiophene or their halogenated derivatives; S2) [...] fatty alcohol and water, under the action of a catalyst, and an oxidizing agent for the selective catalytic oxidation reaction, get chloro-benzene oxygen carboxylic acid. The invention through the re-design of the process route, the catalyst and the chlorinating agent fine screening, effectively reduces the energy consumption, the selectivity of the dichloride to improve at the same time avoiding the losses of the active ingredient, the resulting chloro-benzene oxygen carboxylic acid content can be up to 98.5% or more, the total yield can be up to 99% or more.

Synthesis and Herbicidal Activity of α-(Substituted Phenoxybutyryloxy or Valeryloxy)alkylphosphonates and 2-(Substituted Phenoxybutyryloxy)alkyl-5,5-dimethyl-1,3,2-dioxaphosphinan-2-one
On the basis of our work on the modification of alkylphosphonates 1, a series of α-(substituted phenoxybutyryloxy or valeryloxy)alkylphosphonates (4-5) and 2-(substituted phenoxybutyryloxy)alkyl-5,5-dimethyl-1,3,2-dioxaphosphinan-2-one (6) were designed and synthesized. The bioassay results indicated that 14 of title compounds 4 exhibited significant postemergence herbicidal activity against velvetleaf, common amaranth, and false daisy at 150 g ai/ha. Compounds 5 were inactive against all tested weeds. Compounds 6 exhibited moderate to good inhibitory effect against the tested dicotyledonous weeds. Structure-activity relationship (SAR) analyses showed that the length of the carbon chain as linking bridge had a great effect on the herbicidal activity. Broad-spectrum tests of compounds 4-1, 4-2, 4-9, 4-30, and 4-36 were carried out at 75 g ai/ha. Especially, 4-1 exhibited 100% inhibition activity against the tested dicotyledonous weeds, which was higher than that of glyphosate.

Finding new elicitors that induce resistance in rice to the white-backed planthopper Sogatella furcifera
Herein we report a new way to identify chemical elicitors that induce resistance in rice to herbivores. Using this method, by quantifying the induction of chemicals for GUS activity in a specific screening system that we established previously, 5 candidate elicitors were selected from the 29 designed and synthesized phenoxyalkanoic acid derivatives. Bioassays confirmed that these candidate elicitors could induce plant defense and then repel feeding of white-backed planthopper Sogatella furcifera.

Pesticide-polymer systems prepared from vinyl monomers
Controlled release pesticide-polymer systems are prepared by the polymerization of vinyl monomers containing pendant pesticides. The vinyl monomers are prepared by reacting an acrylic acid derivative with a pesticide or a pesticide derivative having an active hydrogen. The pesticide-polymer systems prepared from the pesticide vinyl monomers release the active pesticide material by hydrolysis or chemical depolymerization under conditions of use.
