Abstract: Copper is broadly toxic to bacteria. The present invention has identified a compound called N,N-dimethyldithiocarbamate (DMDC) and derivatives thereof that combines with copper to prevent the growth of wild type Streptococcus pneumoniae, and even better, kills Streptococcus pneumoniae. Low micromolar levels of DMDC, complexed with biologically relevant amounts of copper, such as those found in the phagolysosome of the macrophage, has a profound effect in killing up to 99.9% of wild type S. pneumoniae in 2 hours. DMDC also works against S. pneumoniae in an animal model of infection, and in vitro against schistosomes and Coccidioides spp. Additionally, the present invention features a method of treating infections caused by the aforementioned pathogenic organisms, as well as others, by administering DMDC to a patient in need thereof.
