DIBA-1 (2,2′-dithiobisbenzamide-1) is a disulfide that interacts with zinc fingers as a zinc ejector. It has been shown to interact with many zinc finger containing proteins, including HIV-1 nucleocapsid and the estrogen receptor. DIBA-1 has been studied as a candidate for the treatment of AIDS and also breast cancer. In one study DIBA restored tamoxifen sensitivity in resistant breast cancer.
