A SYNTHETIC PEPTIDE DISTURBING INTRACELLULAR SIGNALING

摘要

The present invention related to composition and methods for treating cancer. The invention provides peptides derived from small modular domains that are SH2 and SH3 motifs. These domains play critical roles in protein-protein interaction that are important for intracellular location, recruitment of substrates prior to prophosphorylation, redistribution of substrates to receptor complexes, and inactivation or activation of catalytic activity. For intracellular translocation and cancer targeting, these peptides were conjugated with palmitic acid which was previously used to these approaches. The invention is useful for inhibiting signal pathway in cancer cells such as hepatocellular carcinoma, cervical cancer, colon adenocarcinoma, and fibrosacoma.
