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.

摘要:Improved synthetic methods for the production of thaxtomin analogs, particularly thaxtomin A, and intermediates therefore such as substituted tryptophans and in particular, 4-nitro-L-tryptophan, and substituted phenyl acrylic acids are disclosed. Bioassays show that the synthetic thaxtomin A is not significantly different from the natural one in herbicidal activity.
