标题:Hppd抑制剂芳氧基乙酸衍生物的合成及除草活性
摘要:设计并合成了一系列芳氧基乙酸衍生物,作为4-羟基苯基丙酮酸双加氧酶(hppd)抑制剂.初步的生物测定结果表明,这些衍生物是有前途的拟南芥hppd(at Hppd)抑制剂,特别是化合物i12(k I = 0.011 µm)和i23(k I = 0.012 µm),其活性与市售甲基磺草酮相似. Hppd除草剂(k I = 0.013 µm).此外,新合成的化合物在150 G Ai / Ha的剂量下对被测杂草显示出显着的温室除草活性.特别是ii4在芽前处理中表现出较高的除草活性,略高于甲基磺草酮.此外,化合物ii4对于玉米田中150 G Ai / Ha的杂草防治是安全的,并且被确定为新型hppd抑制剂除草剂的最有效候选者.本文所述的化合物可为设计新的抑制hppd的除草剂及其修饰提供有用的指导.

标 题:A cytochrome p450 enzyme associated with the synthesis of delta-12 -epoxy groups in fatty acids of plants
发明人：CAHOON EDGAR B
权利人:DU PONT
摘要:An isolated nucleic acid fragment encoding a cytochrome P450 enzyme associated with the synthesis of plant DELTA12-epoxy fatty acids is disclosed. The invention also relates to making a chimeric construct encoding all or a portion of the cytochrome P450 enzymes associated with the synthesis of plant DELTA12-epoxy fatty acids, in sense or antisense orientation, wherein expression of the chimeric construct results in production of altered levels of the cytochrome P450 enzymes associated with the synthesis of plant DELTA12-epoxy fatty acids in a transformed host cell.

标题 :Method for synthesis of colloidal nanoparticles
发明人：STROUSE GEOFFREY FIELDING; GERBEC JEFFREY A; MAGANA DONNY
权利人:UNIV CALIFORNIA
摘要:A method for synthesis of high quality colloidal nanoparticles using comprises a high heating rate process. Irradiation of single mode, high power, microwave is a particularly well suited technique to realize high quality semiconductor nanoparticles. The use of microwave radiation effectively automates the synthesis, and more importantly, permits the use of a continuous flow microwave reactor for commercial preparation of the high quality colloidal nanoparticles.

权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:One aspect of the present invention relates to optionally substituted halogenated benzyl halides and the like. These compounds are useful as halogenated benzyl ether-based protecting groups for a variety of functional groups. Another aspect of the present invention relates to use of said protecting groups in an orthogonal protecting group strategy for the synthesis of complex molecules that comprise a number of suitable functional groups. Another aspect of the present invention relates to saccharides bearing various arrays of protecting groups of the present invention. Another aspect of the present invention relates to a method of synthesizing an oligosaccharide or glycoconjugate, comprising the steps of: using a saccharide bearing at least one protecting group of the present invention to glycosylate a second molecule to give a product comprising said saccharide; and removing a protecting group of the present invention from said product.
