  1. Results are presented as the mean ± SD of three different replicates. Kd dissociation constant, UDCA-G1 and UDCA-G2 ursodeoxycholic acid glucuronide conjugate 1 and 2 [44], UDPGlcA UDP-glucuronic acid. Molecules with ΔG of < −0.1 and with an SD of ≤0.1 Kcal/mol were selected for further for MD simulations (methotrexate was not selected as it has an SD 0.5). SD is calculated from 8 docking poses or models (default option). The ligand binding pose was selected for further analyses is the pose with the lowest free binding energy (Kcal/mol). Bilirubin was selected for further molecular docking simulations as an endogenous negative control to compare our results with other putative ligands
