What is a drug
A compound which interacts with a biological system to produce a biological response
The therapeutic index
Shows the ratios of concentrations at which a drug is effective versus toxic
ADMET
Absorption Distribution Metabolism Elimination Toxicity
Types of molecular target
Proteins (Enzymes, Receptors, and Ion channels) Lipids Nucleic acids Carbohydrates
Druggability
A target that is capable of binding a small molecule capable of modulating its activity in a therapeutically desirable way
Protein-protein interactions (PPIs)
Modulate a lot of biochemical processes. Large molecules so spread over large surface area. Involves 2 fairly flat surfaces without defined pockets or grooves.
Intermolecular interactions
Salt bridges (strongest)
Hydrogen bonding
Van deer waals (weakest)
