Study Notes
Medicinal Chemistry
- Medicinal chemists study drug synthesis, Structure-Activity Relationship (SAR), Absorption, Distribution, Metabolism, and Excretion (ADME), and mechanism of action
- They design and make new drug compounds and examine how small changes to a molecule affect its biological activity
- They investigate how a drug is absorbed, distributed, metabolized, and excreted in the body to predict its effects
Commercialization
- A drug that proves effective and safe may receive regulatory approval and move onto market authorization
- Companies then manufacture, package, and distribute the drug globally
- Patent protections grant inventors exclusive rights to their invention for a specified period, typically 20 years from the filing date
- This provides incentive for companies to invest in research and development of innovative drugs
Challenges and Opportunities
- Despite advancements in drug design, challenges remain, including understanding complex biology systems, dealing with scientific uncertainty, and ensuring drug quality
- These challenges present opportunities for innovation, collaboration, and groundbreaking developments in understanding diseases and treatments
- They include predicting human response, managing costs, addressing safety concerns, overcoming resistance, promoting accessibility, and navigating ethical issues
Drug Design
- Drug design involves discovering, designing, developing, and commercializing pharmaceutical drugs
- It requires a multidisciplinary approach to develop new medicines and treatments for diseases
Discovery
- The discovery phase focuses on identifying promising compounds that interact with biological targets such as proteins, enzymes, and receptors involved in disease processes
- Techniques like high-throughput screening, molecular modeling, and bioinformatics help identify potential candidates from large libraries of chemicals
Design
- Once a lead compound is identified, it undergoes optimization to improve its properties, such as potency, selectivity, safety, and stability
- This process involves iterative cycles of structural modification and property evaluation until an acceptable candidate emerges
Development
- The selected compound undergoes preclinical testing to evaluate toxicity, efficacy, and dosage regimen
- If successful, the drug enters clinical trials to assess safety and effectiveness in volunteers or patients
- Clinical trials involve increasing numbers of participants across phases, ranging from Phase I (healthy volunteers) to Phase IV (post-marketing surveillance)
Explore the fundamentals of medicinal chemistry including drug synthesis, Structure Activity Relationship (SAR), ADME processes, and mechanisms of drug action within the human body.
