LRRK2 activity model

LRRK2 is a large multi-domain kinase whose gain-of-function mutations, such as G2019S, are a common genetic cause of Parkinson's disease. Kinase inhibitors are being developed as Parkinson's treatments.

A model trained on measured activity data for LRRK2 (Neuroscience). Give it compounds and it predicts their IC50 against LRRK2, so you can rank candidates by it.

How to use it

  1. Under Predict with this model, press TSAP (Boltz-2) or TSAP (AI-QSAR). The wizard of the workflow you pressed opens with the LRRK2 model already selected.

  2. Upload the SMILES of the compounds to predict as a .smi, .csv or .txt file.

  3. Check the estimated credits and time, then submit.

  4. The result is a table of compounds ranked by predicted IC50.

Limitations

  • Predictions can be less accurate for compounds whose structures differ a lot from the training data.
  • Validation used only about 30 compounds, so performance on new compounds can differ from these metrics.
  • Predictions do not replace experiments. Use them to decide what to synthesize and measure first.
