Abstract: The invention relates to antibody drug conjugate (ADC) compounds represented by Formula I: Ab-(L-D)p??I where one or more 1,8 bis-naphthalimide drug moieties (D) having Formulas IIa and IIb are covalently linked by a linker (L) to an antibody (Ab). The invention also relates to pharmaceutical compositions comprising an effective amount of a Formula I ADC for treatment of hyperproliferative disorders and other disorders. The invention also relates to methods for killing or inhibiting the multiplication of a tumor cell or cancer cell including administering to a patient an effective amount of a Formula I ADC.

Abstract: The invention relates to bis 1,8 naphthalimide compounds including antibody drug conjugate (ADC) compounds represented by Formula I: Ab-(L-D)p ??I where one or more 1,8 bis-naphthalimide drug moieties (D) having Formulas IIa and IIb are covalently linked, through the wavy line, by a linker (L) to an antibody (Ab). The invention also relates to heterocyclic-substituted 1,8 bis-naphthalimide compounds having Formula XV The invention also relates to pharmaceutical compositions comprising an effective amount of a Formula I ADC or Formula XV heterocyclic-substituted 1,8 bis-naphthalimide compound for treatment of hyperproliferative disorders and other disorders. The invention also relates to methods for killing or inhibiting the proliferation of tumor cells or cancer cells including administering to a patient an effective amount of a Formula I ADC or Formula XV compound.
