Study Notes
The Science of Medicine: Discovery & Design of Drugs
Lecture 1 Overview
- Discovery and design of drugs: a complex process involving multiple disciplines
- Two main stages: drug discovery and drug development
- Medicinal chemistry plays a key role in the drug discovery process
The Magic Bullet Concept
- Developed by Paul Ehrlich in the early 20th century
- The idea of a "magic bullet" that can target and kill specific bacteria without harming the body
- Led to the development of the first chemotherapeutic agent, Salvarsan 606, to cure syphilis
Drug Discovery Processes
- Identification of a disease and a suitable drug target
- Screening for leads: natural products, synthetic compounds, and biologicals
- Lead optimization: modifying the lead compound to achieve the desired properties
- Preclinical evaluation: in vitro and in vivo tests to assess efficacy, toxicity, and pharmacokinetics
Choosing a Disease and a Drug Target
- Unmet medical needs: identifying diseases with limited treatment options
- Economic factors: considering the cost of development and potential return on investment
- Developing world diseases: often neglected due to limited financial resources
- Philanthropic efforts: organizations like the Wellcome Trust and the Bill & Melinda Gates Foundation
Choosing a Drug Target
- Discovering drug targets through biological effects, observation, and proteomics/genomics
- Identifying suitable receptors, enzymes, and nucleic acids as targets
- Advances in proteomics and genomics have improved understanding of drug targets
- Orphan receptors: targets with unknown ligands
- Compound screening: a common approach to identify potential leads
Target Specificity and Selectivity
- Importance of specificity and selectivity in drug design
- Achieving selectivity between species, e.g., antibacterial targets
- Advantages of selectivity: reduced side effects and improved efficacy
