CDD Models case study #1

  2. 2. MoDELS RESIDE IN PAPERS NOT ACCESSIBLE…THIS IS UNDESIRABLE How do we share them? How do we use Them?
  3. 3. What if we could build Machine Learning Models in the CDD Vault We could then use them to score public or private libraries in the Vault We can leverage models from other companies or groups to help internal projects We can export models to use in other software We can develop our own private database of models Deliverable: This Case Study walks you through building a model with a dataset in CDD Public and generating predictions in a CDD Vault
  4. 4. Open Extended Connectivity Fingerprints ECFP_6 FCFP_6 • Collected, deduplicated, hashed • Sparse integers • Invented for Pipeline Pilot: public method, proprietary details • Often used with Bayesian models: many published papers • Built a new implementation: open source, Java, CDK – stable: fingerprints don't change with each new toolkit release – well defined: easy to document precise steps – easy to port: already migrated to iOS (Objective-C) for TB Mobile app • Provides core basis feature for CDD open source model service Clark et al., J Cheminform 6:38 2014
  5. 5. Using AZ-ChEMBL data for CDD Models
  6. 6. The AZ data is also present in CDD Public
  7. 7. Select actives – you want low values to equal GOOD
  8. 8. Build Model
  9. 9. Model name
  10. 10. Model built
  11. 11. Model ROC PLOT
  12. 12. Predictions for some approved drugs in Vault with Model – select compo
  13. 13. Predictions for some approved drugs in Vault with Model – select model from protocol section
  14. 14. Predictions for some approved drugs in Vault with Model – outp You can rank molecules by these scores
  15. 15. You can create a private database of CDD Models in your CDD Vault
  16. 16. You can also export your CDD Model
  17. 17. Clark et al., JCIM 55: 1231-1245 (2015) Exporting models from CDD
  18. 18. Clark et al., JCIM 55: 1231-1245 (2015)9R44TR000942-02 You can import your model in a mobile app like MMDS for private use of the model or sharing with a collaborator
