Abstract: This disclosure relates to antibody-drug conjugates (ADCs) comprising an anti-Trop-2 antibody. Provided herein are compositions comprising such ADCs, as well as methods of making and using the same.

Abstract: The disclosure provides a method for preparing drug toxin PNU-159682 (morpholinyl anthracycline derivative) for antibody-conjugated drugs and intermediates involved in the preparation method. The preparation method of the present disclosure improves the stability, practicability and scalability of the process by introducing protecting groups and changing to reagents that are capable to amplify; the preparation method of the present disclosure minimizes the risk and operational difficulty during scale-up production; production and operation is simple and convenient.

Abstract: The disclosure provides a method for preparing drug-linker MC-MMAF for antibody drug conjugates and intermediates therein. The preparation method of the present disclosure improves the reactivity of the N-terminal, thereby effectively controlling the occurrence of racemization; does not directly use the toxin MMAF, but uses fragmented peptides with lower toxicity, which minimizes the operational difficulty in scale-up production; no reverse phase is required and it is easy to prepare and operate.
