Patent number: 7338965Abstract: The invention relates to substituted piperidine, piperazine, morpholine and thiomorpholine compounds useful in the treatment of Alzheimer's disease and more specifically to compounds that are capable of inhibiting beta-secretase, an enzyme that cleaves amyloid precursor protein to produce amyloid beta peptide (A-beta), a major component of the amyloid plaques found in the brains of Alzheimer's sufferers. One embodiment of the invention relates to compounds having the structure: where Z is CR or N, and R1, R2 and R3 are as described in the specification.Type: GrantFiled: November 19, 2002Date of Patent: March 4, 2008Assignees: Pharmacia & Upjohn Company, Elan Pharmaceuticals, Inc.Inventors: Joseph B.

Patent number: 6947847Abstract: Disclosed is are methods of generating chemical structures of putative non-peptide inhibitors of biologically-active receptors. The method includes constructing a model of a receptor-ligand complex using empirical three-dimensional data of the receptor-ligand complex. The conformation of the binding site between the receptor and the ligand is then altered to yield novel conformations not exhibited in either the native receptor or the bound receptor. These conformations are then used to generate models of non-peptide chemical structures that are complementary in structure to the altered conformations of the binding site. In this fashion, chemical structures of putative non-peptide inhibitors of the altered conformation are revealed.Type: GrantFiled: March 8, 2002Date of Patent: September 20, 2005Assignee: Wisconsin Alumni Research FoundationInventors: Matthew G. Bursavich, Daniel H. Rich

Patent number: 6316405Abstract: Disclosed are conjugates of A&bgr;-binding peptides and CsA analogs and conjugates of A&bgr;-binding peptides and FK506 Binding Peptide inhibitors. These conjugates chemically induce dimerization of either cyclophilin or FK506 Binding Peptide with A&bgr; peptide, a major component of amyloid plaques found in neurological disorders such as Alzheimer's disease, multiple sclerosis, and amyotrophic lateral sclerosis. The conjugates are useful in the treatment of neurological diseases involving the formation of amyloid plaques because they inhibit and/or prevent the aggregation and deposition of A&bgr; peptide into plaques.Type: GrantFiled: February 22, 1999Date of Patent: November 13, 2001Assignee: Wisconsin Alumni Research FoundationInventors: Daniel H. Rich, Michael E. Solomon

Patent number: 6270957Abstract: Disclosed are cyclosporin analogs having amino acid residue substitutions at positions 1, 3, or 7 of the cyclosporin peptide backbone. Also disclosed are conjugates of these cyclosporin analogs in which an HIV protease inhibitor moiety is conjugated to the position-7 amino acid residue of the cyclosporin. These compounds simultaneously bind to and inhibit cyclophilin and HIV protease. The compounds have good bioavailability and potent HIV inhibitory activity. They are useful in the treatment and prevention of HIV-mediated disorders, including AIDS.Type: GrantFiled: February 22, 1999Date of Patent: August 7, 2001Assignee: Wisconsin Alumni Research FoundationInventors: Daniel H. Rich, Michael E. Solomon

Patent number: 5948693Abstract: The present invention relates generally to cyclosporin analogs, and more paritcularly to methods for the solid-phase synthesis and on-resin cyclization of cyclosporin analogs. Methods are described for the on-resin cyclization of sterically hindered compounds synthesized through solid phase synthesis techniques. The methods utilize solvent, temperature, and washing conditions that allow the efficient on-resin cyclization of compounds like analogs of cyclosporin A.Type: GrantFiled: April 14, 1997Date of Patent: September 7, 1999Assignee: Wisconsin Alumni Research FoundationInventors: Daniel H. Rich, Prakash Raman, Yvonne M. Angell
