Dear Clean-Subset ZINC users

We updated the filtering rules for clean subsets. We were incorrectly filtering out any charged basic amine (!) instead of just quarternary amines and constituitively charged N-alkylated aromatic nitrogens.

The "clean shards" was the first to appear, this morning, to be followed this evening by clean-leads and clean-fragments. "clean-drugs" and "all-clean" will appear by the weekend.

We appreciate your feedback. You can contact us on http://facebook.com/zincdb or tweet us @chem4biology.
