Biological Activity: LD2-3 is a cytotoxic compound derived from Exatecan (HY-13631), designed to be conjugated with anti-FGFR2b or anti-CEA antibodies to form intact antibody-drug conjugate (ADC) molecules. LD2-3 exhibits a remarkable bystander killing effect: it not only effectively kills FGFR2b-positive tumor cells, but also eliminates surrounding FGFR2b-negative cells in co-culture and mixed tumor xenograft models, thereby inducing complete tumor regression. LD2-3 can be used for anti-tumor research in relevant fields such as gastric cancer and lung cancer[1][2].
