标题:Reagents and methods for library synthesis and screening
发明人:SCHREIBER STUART L; BLACKWELL HELEN E; PEREZ FERNANDEZ LUCY; TALLARICO JOHN A
权利人:HUGHES HOWARD MED INST
摘要:The invention provides novel solid supports for the synthesis of compound libraries. The solid supports have the physical capacity to deliver at least 50 nmol of compound and are functionalized with a silicon-containing linker. In one embodiment of the invention the solid support comprises a bead having a diameter of between approximately 400 and 600 μm functionalized with a silicon-containing linker. According to certain embodiments of the invention the bead is a polystyrene bead. According to certain embodiments of the invention the linker is a diisopropylalkyl-substituted silyl ether. The invention further provides grafted polymeric supports such as lanterns functionalized with a silicon-containing linker. n The invention provides methods for screening in which compounds are synthesized on solid supports in a quantity so that a single solid support such as a bead provides a stock solution sufficient to perform hundreds or thousands of biological or chemical assays. The methods include decoding the sequence of chemical reactions used to synthesize the compound by identifying tags incorporated into the compound during synthesis.

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.
