The SMSF now has a 100,000 compound library from Life Chemicals ready for screening. The recent addition of our fourth subset of 25,000 compounds complements the previous sets (added 1/2009, 10/2009 and 9/2015). These sets were chosen to maximize compound diversity and focus around common drug-like criteria. Users may screen individual subsets or the entire LifeChem library. Details are available by contacting SMSF.
