Study Notes
Key Concepts in Drug Design and Development
- The Lipinski rule, or "Rule of Five", is used in drug development to identify compounds with optimal pharmacokinetic properties for clinical trials.
- Oral drugs are absorbed from the gut into the systemic circulation through a combination of passive diffusion, facilitated diffusion, and active transport mechanisms.
- A good lead compound should have sufficient structural complexity and diversity to allow for further optimization through structure-activity relationship (SAR) studies.
- The fragment-based approach to drug design involves screening small, low-molecular-weight fragments to identify compounds that bind to a target of interest.
- The "rule of four" is generally applied to larger compound libraries used for high-throughput screening (HTS), while the "rule of three" is applied to fragment libraries.
- Virtual screening is a computational approach used to identify potential drug candidates by simulating the binding of compounds to a target protein.
- SAR studies involve modifying the structure of a lead compound to investigate the relationship between its structure and biological activity.
- A good clinical candidate compound should have optimal pharmacokinetic properties, such as high potency, selectivity, and bioavailability, as well as low toxicity, metabolic stability, and off-target effects.
- Neuraminidase inhibitors are a class of drugs used to treat influenza virus infections by inhibiting the activity of the neuraminidase enzyme.
- Several oral antiviral drugs for COVID-19 are currently under development or in clinical trials, targeting various proteins involved in the viral life cycle.
- Mechanisms of action for these drugs include inhibition of viral replication, modulation of the immune response, and prevention of viral entry into host cells.
- Drug discovery and development involve a complex process of target identification, hit identification, lead optimization, preclinical testing, clinical trials, and regulatory approval.
