Described herein are compounds and compositions for use in treatment or prevention of an inflammatory bowel disease, gastrointestinal cancer, or a systemic bacterial infection in a subject in need thereof. They subject may be colonized by one or more pathogenic bacterial strains such as B. fragilis, E. faecalis, or C. perfringens. In certain aspects, the disclosure provides a method of diminishing the pathogenic effects of these bacterial stmins by administering a compound that binds to and/or inhibits one or more toxins produced thereby.
