CDD models case study #3
- 1. CASE STUDY #3 SEAN EKINS COLLABORATIVE DRUG DISCOVERY, 1633 BAYSHORE HIGHWAY, SUITE 342, BURLINGAME, CA 94010, USA
- 2. MoDELS RESIDE IN PAPERS NOT ACCESSIBLE…THIS IS UNDESIRABLE How do we share them? How do we use Them?
- 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. 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. Using Kinase data for CDD Models
- 6. The Kinase data is present in CDD Public
- 7. Select actives – >80% inhibition for EPHB1 = active
- 8. Build Model
- 9. Model name
- 10. Model name
- 11. Model ROC PLOT
- 12. Predictions for some approved drugs in Vault with Model – select compounds
- 13. Predictions for some approved drugs in Vault with Model – select model from protocol section
- 14. Predictions for some approved drugs in Vault with Model – output You can rank molecules by these scores
- 15. You can create a private database of CDD Models in your CDD Vault
- 16. You can also export your CDD Model Search under protocols tab
- 17. Clark et al., JCIM 55: 1231-1245 (2015) Exporting models from CDD
- 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
