Utiliziation of uncorrelated multi-point pharmacophores in virtual screening
Mička, Ondřej ; Hoksza, David (advisor) ; Škoda, Petr (referee)
Recently, a new method for ligand based virtual screening was published. It uses pharmacophore fingerprints and statistical methods to create a phar- macophore model which is then used to predict the activity of ligands. In this thesis two possible enhancemets of this method were examined. The first one is the removal of correlated pharmacophores, the second one is the utilization of larger pharmacophores (originally only 3-point pharmacopho- res were used). Both modifications were implemented along with neccessary extension of the RDKit cheminformatics toolkit. Finally, both modifications were experimentally evaluated and compared to the original method. Based on the results, combination of the pharmacophore model with the fingerprint similarity was proposed as another modification and evaluated. 1
