Drugs that target the toxic proteins would be a big boost for treatment against anthrax since antibiotics are not always an effective antidote. Even though most B. anthracis strains are susceptible to antibiotics, there is a certain point during the course of infection, after which so much toxic protein has accumulated, that no amount of antibiotic does any good.
