Provided is oxadiazole linkers and use thereof, more specifically to the compounds represented by formulas (I), (II), and (III), and their use in the preparation of antibody-drug conjugates (ADCs). The ADCs obtained from said oxadiazole linkers have high homogeneity and stability, and could be used effectively for the treatment of various diseases including tumors. The definition of the groups in formula (I), (II), and (III) is the same as that in the description.
Linker-drug intermediates of Formula I are conjugated to antibodies to form antibody-drug conjugates where the drug moiety is an N-methylalaninyl-maytansinoid.
