Publication number: 20200385428Abstract: Presented herein are cyclic peptides that specifically bind to a cell surface molecule, thereby allowing cell/tissue-specific targeting. The cyclic peptides can be attached to an agent, for example, a polypeptide such as an antibody, e.g., a cell-penetrating antibody. Cyclic peptide-containing cell/tissue-specific cell-penetrating antibodies described herein are capable of targeted delivery in a cell type-specific or tissue-specific (i.e., cell/tissue-specific) manner. The cell/tissue-specific cell-penetrating antibodies described herein can be used as an effective anticancer agent for cancer that overexpresses a cell membrane protein that specifically binds to the fused cyclic peptides.Type: ApplicationFiled: August 18, 2020Publication date: December 10, 2020Applicant: ORUM THERAPEUTICS INC.Inventors: Yong Sung KIM, Ji Sun KIM, Jae Yeong PARK, Seong Wook PARK, Sei Yong JUN, Dong-Ki CHOI
