Publication number: 20220098256Abstract: The present invention provides peptides containing the BIG3 polypeptide-binding site in a PHB2 polypeptide, which inhibit the binding between a PHB2 polypeptide and a BIG3 polypeptide, and pharmaceutical compositions containing the peptide. The peptides of the present invention have the ability to bind not to PHB2, whose expression is found in organs throughout the human body, but to BIG3, which is a protein highly expressed specifically in particularly estrogen receptor-positive cancer, and have excellent growth suppressive effects on BIG3-positive cancer cells. Accordingly, the peptides of the present invention are useful as therapeutic agents for breast cancer which can avoid expression of side effects.Type: ApplicationFiled: November 28, 2019Publication date: March 31, 2022Applicants: TOKUSHIMA UNIVERSITY, ONCOTHERAPY SCIENCE, iNC.Inventors: TOYOMASA KATAGIRI, TETSURO YOSHIMARU, AKIRA OTAKA, TAKASHI MIYAMOTO, YASUHIDE OKAMOTO

Patent number: 11091517Abstract: The present invention provides peptides having a structure in which portions of a dominant-negative peptide of BIG3 which inhibits the interaction between BIG3 and PHB2 are replaced by at least two stapling structures. The peptides of the present invention have excellent cell growth inhibiting activity. The cell growth inhibiting activity lasts longer, compared to a single-stapled peptide. Therefore, the peptides of the present invention have a feature suitable for clinical applications in cancer therapy.Type: GrantFiled: July 18, 2018Date of Patent: August 17, 2021Assignees: TOKUSHIMA UNIVERSITY, ONCOTHERAPY SCIENCE, INC.Inventors: Toyomasa Katagiri, Tetsuro Yoshimaru, Takashi Miyamoto, Yasuhide Okamoto

Patent number: 10669310Abstract: The present invention provides peptides containing a structure in which a portion of the dominant negative peptide of BIG3 which inhibits the interaction between BIG3 and PHB2 is substituted with stapling structure(s). Peptides of the present invention have excellent cell growth inhibitory actions.
