权利人:BASF SE
摘要:A subject matter of the present invention is a process for the preparation of effect compound-comprising microparticles M comprising A) the formation of a crude suspension of microparticles A by means of enzymatic polyester synthesis in an inverse miniemulsion comprising enzyme, effect compound and polyester monomers; and B) the polymerization of wall monomers from the group consisting of ethylenically unsaturated monomers, polyisocyanates and polyepoxides in the crude suspension of microparticles A. Furthermore, the present invention relates to microparticles M which can be obtained by means of the process according to the invention and also to an agrochemical formulation comprising microparticles M. In addition, the present invention relates to the use of microparticles M prepared according to the invention as component in colorants, cosmetics, drugs, biocides, plant protection agents, fertilizers, additives for food or animal fodder, or auxiliaries for polymers, paper, textiles, leather, detergents or cleaners. Finally, the invention also relates to a method for combating undesirable plant growth, to a method for combating undesirable insect or acarid infestation on plants and/or for combating phytopathogenic fungi, and to seeds treated with the agrochemical formulation.

标题:Methods and compositions for substituted 2,5-diketopiperazine analogs

摘要:Thaxtomins are phytotoxic secondary metabolites produced in plant pathogenic Streptomyces strains and have received considerable interests as bioherbicides. A cell-free, biocombinatorial approach was developed to produce a thaxtomin library for herbicide development. Combination of biosynthetic enzymes led to the production of 136 substituted 2,5-diketopiperazines, thaxtomin D, thaxtomin B and thaxtomin A analogs in a single pot. Furthermore, rational engineering of TxtA allowed the synthesis of azido-containing thaxtomin analog. Selected unnatural thaxtomins demonstrated improved herbicidal activities. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
