标 题:Combinatorial organic synthesis of unique biologically active compounds
发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

标 题:Electrochemical synthesis of substituted aromatic amines in basic media
发明人：GREGORY THOMAS D; STUTTS KENNETH J
权利人:DOW CHEMICAL CO
摘要:Substituted amino aromatic compounds such as 3-amino-4-hydroxybenzoic acid are prepared by electrolytically reducing the corresponding nitro aromatic compound in a basic medium at temperatures below 60° C. and current densities greater than 50 milliamps per square centimeter. The aminohydroxybenzoic acids are useful in the preparation of polybenzoxazoles which are used to make fibers and composites having high strength and thermal stability.

摘要:The present invention provides a formulation for increasing the synthesis and accumulation of essential oil in aromatic plants and other plants. The formulation disclosed herein comprises a resistance inducer, such as an isomer of amino butyric acid or another amino acid, which is capable of increasing the synthesis of essential oil in an aromatic plant. The formulation may further comprise secondary metabolites as well as a carrier. Aromatic plants that may be used in the present invention include, but are not limited to, rose-scented geranium (Pelargonium graveolens) and menthol mint (Mentha arvensis). The present invention also provides a method of increasing the essential oil content in aromatic crops and other plants.
