SMILES: [Emiltatug ledadotin]
Biological Activity: Emiltatug ledadotin (Emi-Le; XMT-1660) is a B7-H4-targeted antibody-drug conjugate (ADC). Emiltatug ledadotin consists of the tumor-specific anti-B7-H4 monoclonal antibody Emiltatug (HY-P990918) and the linker-payload system Ledadotin (HY-177541), with site-specific conjugation achieved via GlycoConnect click chemistry. Emiltatug ledadotin inhibits the growth of B7-H4-positive cancer cells. Emiltatug ledadotin can be used to study advanced solid tumors with B7-H4 overexpression, particularly breast cancer, ovarian cancer, and endometrial cancer[1][2].
