Receptors 4 Flashcards
What is the Lock and Key model
the interaction of the a drug (ligand) with a receptor (protein) is sometimes described as analogous to a lock and key fit in which the drug is complementary to the receptor.
In a lock and key model the drug and receptor are described as what?
rigid
does the lock and key model have high specificity?
yes it does have high specificity.
What is the induced fit model?
this hypothesis has been described as “a hand in a glove”, where the hand and the glove both adjust their shapes to provide an optimal fit. The protein receptor changes conformation on binding to its ligand (drug)
What is the conformational -selection model?
this model suggest the protein receptor fluctuates among several conformational states. Only some of these conformational states allow binding to its ligand
What are some drug targets?
proteins -receptors -enzymes -binding sites nonprotein -DNA
What is pharmacophore?
minimum chemical features necessary to elicit the biological response at a given biological target
Pharmacodynamics
the study of the effects of drugs on the body. This includes the interactions of drugs with their biological targets
