    – be administered by the most desired route (generally orally)
    at minimal dosage and dosing frequency
    – have optimal onset and duration of activity
    – exhibit no side effects

34
Q

What are the methods of Drug Discovery?

A
  • research programs of screening
  • molecular modification
  • mechanism-based drug design
35
Q
  • involves the testing of large numbers of synthetic organic compounds or substances of natural origin for biologic activity
  • may be used initially to detect an unknown activity of the test compound or substance or to identify the most promising compounds to be studied by more sophisticated nonrandom or targeted screens to
    determine a specific activity.
A

Random or untargeted screening

36
Q
  • is a chemical alteration of a known andpreviously characterized organic compound (frequently a lead compound) for the purpose of enhancing its usefulness as a drug.
  • enhancing its specificity for a particular body target site, increasing its potency, improving its
    rate and extent of absorption,     modifying to advantage its time course in the body, reducing its toxicity, or changing its physical or chemical properties (e.g., solubility) to provide desired features
A

Molecular modification

37
Q

–also known as beta-adrenergic blocking
agents, are medications that reduce
your blood pressure.

A

Beta blockers

38
Q

– reduce the amount of acid produced by the cells in the lining of the stomach
– also called ‘histamine H2-receptor antagonists’ but are commonly called H2 blockers.

A

H2 blockers

39
Q
  • is molecular modification to design a drug that interferes specifically with the known or suspected biochemical pathway or mechanism of a disease process
  • is the interaction of the drug with specific
    cell receptors, enzyme systems, or the
    metabolic processes of pathogens     or
    tumor cells, resulting in a blocking,
    disruption, or reversal of the disease
    process
A

Mechanism-based drug design

40
Q

the active metabolite of enalapril (Vasotec), which inhibits the angiotensin-converting enzyme (ACE) that catalyzes the
conversion of angiotensin I to the vasoconstrictor substance angiotensin II. Inhibition of the enzyme results in decreased plasma angiotensin II, leading to decreased vasopressor effects and lower blood pressure

A

enalaprilat
