Assembling data sets for training ML bioactivity models

Molecular Design

A bioactivity data set assembled in this manner would have a single bioactivity data value for each compound and I would take a look at how many compounds that data is available for because it might be possible to use this information for deciding whether or not to build a QSAR-like ML model.

Target-directed cancer: protein-ligand interactions  

Drug Target Review

We often screen using a biochemical assay, but we can conduct cell-based screening as well. For fragment screening, we can screen with biophysical methods, such as thermal shift assays or, you may have heard about Surface Plasmon Resonance (SPR) which is a very sensitive biophysical technique used for fragment screening.

Variability in biological activity measurements reported in the drug discovery literature

Molecular Design

In the Compatibility Issues section the authors state: Looking beyond laboratory-to-laboratory variability of assays that are nominally the same, there are numerous reasons why literature results for different assays measured against the same “target” may not be comparable. and f > 1.0 and 27% are greater than 1.0.
