StarDrop’s ADME QSAR module

Before committing resources to in vivo and in vitro studies, it’s vital to know you’re working with the best molecules. StarDrop’s ADME QSAR module helps you to predict a wide range of ADME 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.

High-quality models

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

– Most acidic pKa
– Most basic pKa
– All pKa values
logP (Octanol/Water)
logD7.4 (Octanol/buffer at pH 7.4)
– Aqueous Solubility
– PBS Solubility pH 7.4
HIA (Human Intestinal Absorption)
CNS Penetration (Blood-Brain Barrier)
Cytochrome P450 Affinities
– CYP2C9
– CYP2D6
P-gp Transport
Plasma Protein Binding

How ADME QSAR works

Try the ADME QSAR module

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.
