Study Notes
Drug Discovery
- The process begins with finding a lead compound, which is an active naturally sourced or synthetic compound.
- The steps to find a lead compound include:
- Choosing a disease and a drug target
- Identifying a bioassay
- Finding a lead compound
- Isolating and purifying the lead compound
- Determining the structure of the lead compound
Drug Design
- The goal of drug design is to identify structure-activity relationships (SARs) and the pharmacophore.
- This involves improving target interactions (pharmacodynamics) and pharmacokinetic properties.
Drug Development
- The process involves several stages, including:
- Patenting the drug
- Conducting preclinical trials, which include:
- Drug metabolism studies
- Toxicology studies
- Formulation and stability tests
- Pharmacology studies
- Designing a manufacturing process (chemical and process development)
- Conducting clinical trials
- Registering and marketing the drug
Key Facts
- The entire process of drug discovery, design, and development can take over 15 years.
- It can involve the synthesis of over 10,000 compounds.
- The total cost can be around $2.5 million USD.
