PAINS Substructure Filters as SMARTS

Sometime back Baell et al published an interesting paper describing a set of substructure filters to identify compounds that are promiscuous in high throughput biochemical screens. They termed these compounds Pan Assay Interference Compounds or PAINS. There are a variety of functional groups that are known to be problematic in HTS assays. The reasons for […]

Some More Comparisons with the GSK Dataset

My previous post did a quick comparison of the GSK anti-malarial screening dataset with a virtual library of Ugi products. That comparison was based on the PubChem fingerprints and indicated a broad degree of overlap. I was also interested in looking at the overlap in other feature spaces. The simplest way to do this is […]
