Download Blood-Brain Barrier in Drug Discovery: Optimizing Brain by Li Di, Edward H. Kerns PDF

By Li Di, Edward H. Kerns

Focused on vital frightened process (CNS) drug discovery efforts, this publication educates drug researchers in regards to the blood-brain barrier (BBB) to allow them to have an effect on vital advancements in a single of the main major – and so much hard – components of drug discovery.

• Written via global specialists to supply functional suggestions to extend mind penetration or reduce CNS side-effects
• Reviews state of the art in silico, in vitro, and in vivo instruments to evaluate mind penetration and complicated CNS drug supply strategies
• Covers BBB body structure, medicinal chemistry layout rules, loose drug speculation for the BBB, and delivery mechanisms together with passive diffusion, uptake/efflux transporters, and receptor-mediated processes
• Highlights the advances in modelling BBB pharmacokinetics and dynamics relationships (PK/PD) and physiologically-based pharmacokinetics (PBPK)
• Discusses case reports of winning CNS and non-CNS medicinal drugs, classes realized and paths to the market

Example text

Transport processes which determine the BBB transfer of the drug between blood and brain (as the measure of the rate and extent of brain penetration) 3. Intrabrain distribution of the drug (as the key element to determine the active site concentration of the drug in the effect compartment) 4. Elimination of the drug from the CNS (often with ISF bulk flow into the CSF or back to blood across BBB) PK Measurements, PK Parameters, and Key Equations This paragraph focuses on those PK parameters and equations which are most c­ ritical for the understanding and optimization of CNS penetration and distribution of compounds in a drug discovery setting.
