StarDrop Modules


High quality predictive QSAR models of key ADME properties

Before committing resources to in vivo and in vitro studies, it’s vital to know you’re working with the best molecules. StarDrop is built to help you predict a wide range of ADME models and physicochemical properties in silico, allowing you to explore all your options and giving you confidence in your decisions – and all with an intuitive, interactive graphical interface.

ADME QSAR StarDrop Module cover

High-quality models

This module enables you to predict a broad range of ADME and physicochemical properties using a suite of high-quality QSAR models including:

  • Human Intestinal Absorption
  • CNS (Blood-Brain Barrier) Penetration
  • Cytochrome P450 Affinities
    – CYP2C9
    – CYP2D6
  • P-gp Transport
  • hERG
  • Plasma Protein Binding

Model validation

Independent test sets are used to validate every model.

Prediction confidence

Every prediction is accompanied by an estimate of confidence, helping you to fully consider uncertainties.

Chemical space

The applicable chemical space is captured for each model. Molecules outside this space – where confidence in the predictions are lower – are clearly identified.


StarDrop interfaces with in-house models to supplement or replace StarDrop’s optional models. StarDrop models can also be run from other informatics platforms.

Glowing Molecule

The StarDrop ADME QSAR models provide Glowing Molecule results.



The predictive ADME QSAR models are available as an optional module for StarDrop. To find out more about StarDrop and the ADME QSAR models, to arrange an online demonstration or to try StarDrop for yourself, please contact us.
