Patent number: 6653087Abstract: Targeted C2-symmetric and unsymmetric chemical libraries for use in protein and receptor homodimerization and heterodimerization are constructed by solution phase methodologies. Exemplary libraries are prepared in a 60 to 10 sub-library format by symmetrical coupling of the constructed fragments with a mixture of tethering dicarboxylic acids. In each step of the 3-step reaction sequence, the reactants, unreacted starting material, reagents and their byproducts were removed by simple liquid-liquid or liquid-solid extractions providing the desired intermediates and final libraries in multi-milligram quantities in high purities (≧90-100%) independent of the reaction yields and without deliberate reaction optimization. The synthesis of a second prototypical library employed the olefin metathesis reaction to join and combinatorially randomize the length of linker tether.Type: GrantFiled: August 9, 1999Date of Patent: November 25, 2003Assignee: The Scripps Research InstituteInventor: Dale L.

Patent number: 6566553Abstract: The present invention is directed to an improved synthesis of clasto-lactacystin-&bgr;-lactone, and analogs thereof, that proceeds in fewer steps and in much greater overall yield than syntheses described in the prior art. The synthetic pathway relies upon a novel stereospecific synthesis of an oxazoline intermediate and a unique stereoselective addition of a formyl amide to the oxazoline. Also described are novel clasto-lactacystin-&bgr;-lactones, and analogs thereof and their use as proteosome inhibitors.Type: GrantFiled: August 10, 2001Date of Patent: May 20, 2003Assignee: Millennium Pharmaceuticals, Inc.Inventors: François Soucy, Louis Plamondon, Mark Behnke, William Roush
