Outline of Final Research Achievements |
Peptidomimetics that mimic conformation such as secondary and tertiary structures of peptides/proteins have led to the recent development of anti-cancer and anti-HIV agents. Some examples are described as follows. Chemokine receptor CXCR4 antagonists based on cyclic peptides having conformationally constrained structures have been synthesized as agents with anti-chemotactic activity against cancer cells and inhibitory activity against HIV entry. HIV protein-derived stapled peptides with helix mimetics have been developed as HIV integrase inhibitors. Dimer and trimer mimetics of a C-terminal helical region (CHR/C34) of an envelope protein gp41 have been developed as HIV fusion inhibitors. In addition, bivalent ligands based on the above CXCR4 antagonists such as 14-mer peptide T140 derivatives have been synthesized to produce effective metastatic inhibition with the therapeutic potential. Taken together, these advantaged of mid-size drugs were shown.
