… is that really necessary?Hows about interoperability and
integration?
Wouldn’t it be nice being able to switch seamlessly between
scientific domains and find data that you have not even thought about, but would be important?

ACCESS TO KNOWLEDGE ALONG DRUG DISCOVERY CHAIN
- Focused Library- hERG Model- CYP Model
- Indications for target- Compound active on target- Most active compounds (IC50, Ki, EC50 < 50nM)- Most active competitors- Target selectivity- PK of Compounds classes- Adverse effects : CYP-blockade- Adverse effect : hERG-activity
- Calcium T Type Channel- Hit Generation : customer story- Phenotypic in silico Screening
- High affinity towards the target - Show selectivity versus targets- Reduce binding to HSA- Improve cell permeability- Not be metabolized rapidly- Not interfere with the P450 enzymes-Not interfere with the Pgp- Show selectivity versus targets (Advanced)- Multiple inhibitors : Renin angiotensin pathway
- Exploration of structural features of a lead series of Compounds-Safety pharmacology (off Targets) - Pharmacokinetics- ADMET - Computational chemistry and molecular modeling

AKT1 INHIBITORS
17
DR. OLIVIER BARBERAN | SEPTEMBER 2013| ELSEVIER
AKT INHIBITORS
• AKT IS ASSOCIATED WITH TUMOR CELL SURVIVAL, PROLIFERATION, AND INVASIVENESS.
• THE ACTIVATION OF AKT IS ALSO ONE OF THE MOST FREQUENT ALTERATIONS OBSERVED IN HUMAN CANCER AND TUMOR CELLS.
• Akt1 has been implicated as a major factor in many types of cancer
• Akt2 is an important signaling molecule in the Insulin signaling pathway
• The role of Akt3 is less clear, though it appears to be predominantly expressed in the brain
THEREFORE, UNDERSTANDING AKT AND ITS PATHWAYS IS IMPORTANT FOR THE CREATION OF BETTER THERAPIES TO TREAT CANCER AND TUMOR CELLS.
DR. OLIVIER BARBERAN | SEPTEMBER 2013| ELSEVIER
ABOUT AKT1 INHIBITORS IN REAXYS MEDICINAL CHEMISTRY
• MOST ACTIVE COMPOUNDS ON AKT1 (IC50, KI OR KD BELOW 0.05 ΜM?)
• TARGET SELECTIVITY (AKT1 VERSUS AKT2)
• PK OF COMPOUNDS CLASSES
• ADVERSE EFFECTS : CYP-BLOCKADE
• ADVERSE EFFECT : HERG-ACTIVITY
