  • Patent number: 11820833
    Abstract: An isolated peptide of up to 6 amino acids comprising an amino acid sequence which inhibits binding of an endothelial cell protein C receptor (EPCR) ligand to the EPCR is disclosed. Also disclosed is an isolated peptide comprising an amino acid sequence which inhibits binding of an endothelial cell protein C receptor (EPCR) ligand to the EPCR, wherein the peptide comprises a modification in at least one amino acid. Also disclosed is a molecule comprising an amino acid sequence which inhibits binding of an endothelial cell protein C receptor (EPCR) ligand to the EPCR attached to a heterologous moiety. Pharmaceutical compositions and methods of treatment are also disclosed.

  • Publication number: 20050119237
    Abstract: Disclosed is a method for inhibiting Ras-induced or mediated proliferation of cells associated with a non-malignant disease, disorder or pathological condition. The method entails administering to a patient a Ras antagonist in an amount effective to inhibit the proliferation. The invention is particularly applicable to diseases characterized by a proliferation of T-cells such as autoimmune disease, e.g., type 1 diabetes, lupus and multiple sclerosis, and pathological states such as graft rejection induced by the presentation of a foreign antigen such as a graft in response to a disease condition (e.g., kidney failure). Other non-malignant diseases characterized by proliferations of cells include cirrhosis of the liver and restenosis. Preferred Ras antagonists are S-trans-trans farnesylthiosalicylic acid (FTS) and structurally related compounds (or analogs) thereof.
