The invention relates to 2-methylbenzoxazole compounds of formula I which are analogues of the DNA alkylating subunit of the duocarmycins. Compounds of formula I can be used in the synthesis of DNA alkylating agents and antibody-drug conjugates and related compounds. The 2-methylbenzoxaxole unit of formula I has advantageous properties in combining high cytotoxicity, low lipophilicity, and unusual aqueous stability, all of which are desirable for application as payloads in efficacious antibody-drug conjugates.
