Abstract

Modern high throughput drug discovery approaches have increased the numbers of lead compounds being identified, and in shorter time frames than traditional medicinal chemistry, however many of these promising compounds often fail because of unsatisfactory ADMET properties. In silico screening approaches help to reduce these risks. Here we propose a novel approach to the prediction of pharmacokinetic properties, called pkCSM, which relies on graph-based signatures. These encode distance patterns between atoms and are used to represent the small molecule and to train predictive models.

The pkCSM signatures were successfully used across five main different pharmacokinetic properties classes to develop predictive regression and classification models. We show that pkCSM performs as well or better across different pharmacokinetic properties than other freely available methods. Here we present a web server to provide an integrated freely available platform to rapidly screen multiple pharmacokinetic properties.
