Abstract: The present invention provides phenylalanine derivatives that inhibit SH2 domain binding with a phosphoprotein. These derivatives include compounds of the formula: W—Y-(AA)n-Z wherein n is 0 to 15; Y is a phenylalanyl radical having a phenyl ring, an amine end, and a carboxyl end, the phenyl ring having one or more substituents, e.g., hydroxyl, carboxyl, formyl, carboxyalkyl, carboxyalkyloxy, dicarboxyalkyl, dicarboxyalkyloxy, dicarboxyhaloalkyl, dicarboxyhaloalkyloxy, and phosphonoalkyl, or phosphonohaloalkyl; W is a moiety attached to the nitrogen of Y and is, e.g.

Abstract: Disclosed herein are phenylalanine derivative compounds of the following formula W—Y—(AA)n—Z wherein Y is a phenylalanyl radical, AA is an amino acid, n is an integer of 1 to 15, and substituent variables W and Z are as described herein. The compounds can be used to inhibit SH2 binding with phosphoproteins, and to inhibit proliferation of tumor cells.

Abstract: Disclosed are methods of inhibiting cell motility, for example, by inhibiting the binding between an intracellular transducer and a receptor protein tyrosine kinase, and more particularly by inhibiting hepatocyte growth factor (HGF) induced cell motility. The present invention also provides a method of inhibiting angiogenesis. The methods of the present invention employ peptides such as phosphotyrosyl mimetics. The present invention further provides methods of preventing and/or treating diseases, disorders, states, or conditions such as cancer, particularly metastatic cancer comprising administering to a mammal of interest one or more peptides of the present invention.

Abstract: The invention relates to an acylated peptide, namely a compound of formula (I), wherein n is 0 to 15, X is oxalyl PTI is the bivalent radical of tyrosine or (preferably) the bivalent radical of phosphotyrosine or a phosphotyrosine mimetic, AA stands for a bivalent radical of a natural or unnatural amino acid, and Y is secondary amino group, or a salt thereof, said compound being useful for the treatment of diseases that respond to inhibition of the interaction of (a) protein(s) comprising (an) SH2 domain(s) and a protein tyrosine kinase or a modified version thereof.
