COVID_moonshot_data_clean

This repository contains comp chem/ML-ready versions of the data in https://github.com/asapdiscovery/COVID_moonshot_submissions. This data has all been downloaded from the COVID Moonshot CDD Vault.

The IC50 measurements in this repository were measured using the fluorescence inhibition assay described in

On suspected_SMILES: Note that many of the enantiopure compounds on this project were obtained by chiral separation, and thus the compounds are often obtained as a single enantiomer with unknown absolute stereochemistry. The suspected_SMILES column represents the current understanding of the actual identity of the compound given the current information, which explains the frequent use of enhanced/relative stereochemistry representations.

Files

• cdd_noncovalent_dates_2023_10_18_filt.csv: All noncovalent available data as of October 10, 2023, filtered to remove data without a noted SMILES string or IC50 value. Note that some of the entries in this dataset are racemates.
• cdd_achiral_enantiopure_dates_2023_10_18_filt.csv: All noncovalent available data as of October 10, 2023, filtered to contain only achiral and enantiopure molecules.

Column Headers

A brief explanation of each column present in the CSV files.

• suspected_SMILES: SMILES string of the synthesized molecule
• Canonical_PostEra_ID: Molecule's canonical name
• IC50_(µM): Experimental IC50 value, in µM units. Unless otherwise noted in the file description, these values are semi-quantitative, meaning that some values may have been outside the range of the assay used. The semi-quantitativeness of a given measurement is given by the Semiquant field
• IC50_CI_(Lower)_(µM): Lower bound of the 95% CI of the experimental IC50 value, in µM units
• IC50_CI_(Upper)_(µM): Upper bound of the 95% CI of the experimental IC50 value, in µM units
• Hill_slope: Calculated slope of the Hill equation for this measurement
• CDD_curve_class: Calculated curve class from CDD for this measurement
• Semiquant: Whether the given compound was too strong of a binder to be resolved ("Strong"), too weak of a binder to be resolved ("Weak"), or within the assay range ("Quant")
