ZINC is a publicly available database that aggregates commercially available and annotated compounds. ZINC provides downloadable 2D and 3D versions as well as a website that enables rapid molecule lookup and analog search. ZINC has grown from fewer than 1 million compounds in 2005 to nearly 2 billion now. This dataset includes ~1B molecules in total. We have filtered out any compounds that were not avaible to be converted from smiles to seflies representations.

Data Splits

The dataset is split into an 80/10/10 train/valid/test random split across files (which roughly corresponds to the same percentages)

Source Data

Initial Data Collection and Normalization

Initial data was released at https://zinc20.docking.org/. We have downloaded and added a selfies field and filtered out all molecules that did not contain molecules that could be converted to selfies representations.
