Project Retired. The Drug Design and Optimization Lab (D2OL)™ works to discover drug candidates against Anthrax, Smallpox, Ebola and SARS and other potentially devastating infectious diseases. By simply downloading a no cost, non-intrusive software application, you can contribute the idle time available on your computer to emerging microbial diseases and other pathogens that significantly impact global health even when not connected to the Internet. D2OL, was first to use computational methods to deploy targets against Anthrax, Smallpox and Ebola, and now is first to have a credible SARS target (A target conserved between pig and human coronovirus, the suspected virus behind SARS).
