Large-scale docking approaches to the kinomeDenis Schmidt*, Peter Kolb

From 9th German Conference on ChemoinformaticsFulda, Germany. 10-12 November 2013

Docking nowadays is a widely used tool and has success-fully and repeatedly been applied to identify hits with newchemical scaffolds [1]. Despite its successful applications,docking still suffers mainly form its scoring functions,which tend to be optimized for speed to the disadvantageof accuracy. Because of that, docking successfully enrichesactive molecules compared to inactive ones, however thefalse positive rate in docking runs is still very high. Severalattempts have been made to improve docking by applyingconsensus scoring approaches using multiple structures orsoftwares or by rescoring compounds using normalizationprocedures [2-4]. At the same time, the number of largedatasets of activity data derived from high-throughputscreening methods has strongly increased during the lastyears, especially for kinases, allowing re-evaluation of thesetechniques [5-7]. We herein carried out a large-scale dock-ing approach using 650 different kinase crystal structures.To the best of our knowledge, this is the largest numberof targets docked to at the same time. Subsequently, differ-ent normalization techniques were re-evaluated using theexperimental activity data as target function. Furthermore,we investigated the similarity of the kinase structureswithin the “docking universe” and correlated these simila-rities with other similarity metrices.
