A nitrile group is an attractive covalent bonding warhead for cysteine proteases because the proximity of the HIS(41) residue facilitating the formation of the SG-C(=N-H)R binding complex. Selectivity is then possible by non-covalent interactions elsewhere in the binding site. This selection of 500 molecules from nearly 8,000 commercially available nitriles in the ChemBridge Express Pick collection are predicted to bind using the THINK software (https://treweren.com) into the 6WNP crystal structure (which has a slightly more favourable geometry than 5RF7). These hits were partitioned by lipophilicity (as calculated by the software) in to 5 sets. This is set 2 of 5.
A SD file of the 3D binding coordinates is available.
