LD2-3
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.

体外実験
BGA3457 (anti-FGFR2b antibody BGAh9179 conjugated to LD2-3) (34.75 ng/mL) exhibits potent bystander killing activity against FGFR2b-negative HuTu-80-NanoLuc cells cocultured with FGFR2b-positive SNU-16 cells, with an IC50 of 34.75 ng/mL and a maximum killing potency of 90.74%[1].
BGA3457 and BGA9823 (anti-FGFR2b antibodies conjugated to LD2-3) exhibit comparable internalization activity in SNU16, SNU601-h2b, H1048-h2b, and HSC-39 cell lines[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Topics Organoid Co-culture Models in Tumor Immunology
Organoid co-culture models in tumor immunology are three-dimensional experimental systems that combine patient-derived or stem cell-derived tumor organoids with immune cells and other components of the tumor microenvironment to recapitulate tumor-immune interactions in vitro.
