From the US Environmental Protection Agency, ToxCastDB provides public access to data gathered by the ToxCast project that screens chemicals for potential human toxicity using more than 500 high-throughput screening bioassays from nine bioassay vendors. ToxCast is part of the EPA's National Center for Computational Toxicology. As the Basic Info link states, ToxCast links "biological, metabolic and cellular pathway data to gene and in vitro assay data for the chemicals screened."
