Study Notes
Innovation Deficit of New Chemical Entities
- The main issue is the decline in the number of new medicines being approved despite increasing R&D investments.
Drug Discovery Process
- The process is often referred to as a wasteful game due to the high failure rate of candidate compounds, with up to 90% of them failing to reach the market.
Drugability
- In drug design, drugability refers to the likelihood of a biological target being modulated by a small molecule.
Hit Compounds vs Lead Compounds
- Hit compounds are molecules that show preliminary activity against a target, while lead compounds are optimized hit compounds that have been validated through further testing.
- Lead compounds are chosen based on their potency, selectivity, and pharmacokinetic properties.
Testing Validated Compounds
- Currently, biochemical assays, cell-based assays, and animal models are used for testing validated hit or lead compounds.
Hit to Lead Criteria
- A hit must fulfill certain criteria to be accepted as a lead compound, including:
- Sufficient potency and selectivity
- Favorable pharmacokinetic properties
- Low toxicity and good safety profile
- Ability to be formulated and delivered effectively
