Each SAVI product has been annotated with over 60 properties, including data about the BBs and proposed reaction (catalog numbers, reactants, general conditions, protection, predicted yield etc.), identifiers/representations of both the BBs and the product, as well as "drug design" properties such as Lipinski RO5/RO3 violations, PAINS filter matches, FSP3 (fraction of sp 3 hybridized carbons), and log P. The complete list is available on the SAVI Download web page as well as in sections 1 and 2 of Supplementary Information 1. Section 3 of Supplementary Information 1 shows the fields written in SD file format of a SAVI product file. We are also computing and will make available in the future about 100 different ADME/Tox properties using the program ADMET Predictor (Simulations Plus, Lancaster, CA).
