ADC Payload (ADC Cytotoxin)

ZD06519 is a potent ADC cytotoxin and a topoisomerase I inhibitor derived from camptothecin. It exhibits a significant bystander effect, effectively inhibiting various malignancies, including HER2-positive and FRα-overexpressing tumors. By interfering with DNA cleavage, relaxation, and reconnection, ZD06519 induces apoptosis in tumor cells. This compound is ideal for ADC synthesis and applications in cancer research.

Dxd (Exatecan derivative for ADC) is a potent DNA topoisomerase I inhibitor, with an IC50 of 0.31 μM, used as a conjugated drug of HER2-targeting ADC (DS-8201a).

Mertansine (DM1) is a microtubulin inhibitor and is an antibody-conjugatable maytansinoid that is developed to overcome systemic toxicity associated with maytansine and to enhance tumor-specific delivery.

altobulin (HTI-286; SPA-110) is an analogue of Hemiasterlin; potent tubulin inhibitor; ADCs cytotoxin.

C-11 is a tubulin inhibitor and acts as a ADC cytotoxin, displays cytotoxicity for carcinoma cell lines.
