Exocyclic peptide mimetics that disable Fas were developed. A three dimensional model of the Fas receptor-ligand complex was constructed and structurally predicted regions of the receptor that were relevant to binding ligand were used to create constrained peptide mimetics. Exocyclic anti-Fas peptide mimetics were identified that block Fas receptor-ligand interactions, and modulate Fas biological activity both in vitro and in vivo. The mimetics are useful, e.g., for treating Fas-related pathologies.

1. A method of treating a FAS-related pathology comprising administering to a mammal suffering from said FAS-related pathology a therapeutically effective amount of a Fas mimetic represented by the formula (I) wherein B1 and B9 are independently a peptide of 1-6 genetically encoded amino acids, at least one of which is a genetically encoded hydrophobic amino acid, or a genetically encoded aromatic amino acid,Z2 is cysteine, that forms a covalent linkage with B1, X3 or X4 and Z8,Z8 is cysteine, that forms a covalent linkage with B9, X7 and Z2,X3 is a genetically encoded hydrophilic amino acid or null,X4 is aspartic acid or glutamic acid,X5 is aspartic acid or glutamic acid,X6 is selected from the group consisting of histidine, lysine, arginine, asparagine or glutamine,X7 is a genetically encoded aromatic amino acid,“—” is a covalent linkage comprising an amide or a substituted amide thereof, and“═” is a covalent linkage,or a pharmaceutically acceptable salt thereof,wherein said FAS-related pathology is selected from the group consisting of rheumatoid arthritis, Sjogren's syndrome, multiple sclerosis, hepatitis, retinal neovascularization, corneal neovascularization, renal injury, graft rejection, HIV infection and macular degeneration. 2. The method of claim 1 wherein said FAS-related pathology is selected from the group consisting of hepatitis and renal injury. 3. The method of claim 1 wherein said mammal is a human. 4. The method of claim 1 wherein said mimetic is administered as a pharmaceutically acceptable composition. 5. The method of claim 3 wherein said mimetic is administered via an oral, parenteral, intranasal, sublingual, rectal or inhalatory route, or by insufflation, transdermal patches or lyophilized composition. 6. The method of claim 5 wherein said mimetic is administered in an amount of between about 0.01 to about 25 mg/kg/day. 7. The method of claim 6 wherein said mimetic is administered in an amount of between about 0.1 to about 10 mg/kg/day. 8. The method of claim 7 wherein said mimetic is administered in an amount of about 0.2 to about 5 mg/kg/day. 9. The method of claim 5 wherein said mimetic is administered at a total daily dose of about 25 to about 1000 mg. 10. The method of claim 9 wherein said mimetic is administered at a total daily dose of about 150 to about 500 mg. 11. The method of claim 9 wherein said mimetic is administered at a total daily dose of about 350 mg. 12. A method of treating a FAS-related pathology comprising administering to a mammal suffering from said FAS-related pathology a therapeutically effective amount of a Fas mimetic having an amino acid sequence selected from the group consisting of YCDEGHLCY (SEQ ID NO:1); YCDEGLCY (SEQ ID NO:2); YCDEGYFCY (SEQ ID NO:3); YCDEGEYCY (SEQ ID NO:4); YCDEHFCY (SEQ IN NO:5); YCDEHGLCY (SEQ ID NO:6); YCDEHGQCY (SEQ ID NO:7); YCDEKFCY (SEQ ID NO:8); YCDEQFCY (SEQ ID NO:9); YCNSTVCY (SEQ ID NO:10); YCDKAEHFCY (SEQ ID NO:11); YCNTRTQNTCY (SEQ ID NO:12); YCQEKEYCY (SEQ ID NO:13); and YCQERKEYCY (SEQ ID NO:14) wherein said FAS-related pathology is selected from the group consisting of, rheumatoid arthritis, Sjogren's syndrome, multiple sclerosis, hepatitis, retinal neovascularization, corneal neovascularization, renal injury, graft rejection, HIV infection and macular degeneration. 13. The method of claim 12 wherein said FAS-related pathology is selected from the group consisting of hepatitis and renal injury. 14. The method of claim 12 wherein said mammal is a human. 15. The method of claim 12 wherein said mimetic is administered as a pharmaceutically acceptable composition. 16. The method of claim 14 wherein said mimetic is administered via an oral, parenteral, intranasal, sublingual, rectal or inhalatory route, or by insufflation, transdermal patches or lyophilized composition. 17. The method of claim 16 wherein said mimetic is administered in an amount of between about 0.01 to about 25 mg/kg/day. 18. The method of claim 17 wherein said mimetic is administered in an amount of between about 0.1 to about 10 mg/kg/day. 19. The method of claim 18 wherein said mimetic is administered in an amount of about 0.2 to about 5 mg/kg/day. 20. The method of claim 16 wherein said mimetic is administered at a total daily dose of about 25 to about 1000 mg. 21. The method of claim 20 wherein said mimetic is administered at a total daily dose of about 150 to about 500 mg. 22. The method of claim 20 wherein said mimetic is administered at a total daily dose of about 350 mg.
