ADRENERICS… Consider the structures shown here for the questions below: *** a)  Define the term AGONIST: [blank1] *** b) Define the term ANTAGONIST: [blank2]  *** c) Drug (ii) is called albuterol and is used to treat the respiratory disease known as asthma. Albuterol is an agonist that binds in a similar manner compared to an endogenous neurotransmitter, compound (i.). Name compound (i.) [blank3] *** d)  Drug (iii) is called propranolol and it is an antagonist compared to compound (i.). Briefly describe the pharmacophore common to all three structures (i. ii. and iii.) [blank4] *** e) Briefly, how do the varying structures shown above lead to their agonist or antagonist activity? [blank5] *** f)  Rank the drugs in order from most water soluble to least water soluble: [blank6] Structure (i.) is a “Catecholamine”, where the catechol portion is circled in the figure below. It undergoes metabolism to an inactive compound. *** g) Provide a generic name for an enzyme that could complete this metabolic reaction. [blank7]

ANTIFUNGALS … Antifungal drugs exploit the biochemical differences between healthy cells and infected cell. *** a) The “azole” class of antifungal drugs, function by inhibiting the production of what sterol that is unique to fungi? [blank1] *** b) What is the sterol found in normal mammalian cell membranes? [blank2] *** c) Consider the portion of the biosynthesis pathway for a key component of the fungal membrane … What type of enzyme is responsible for this reaction? [blank7] *** d) Name an antifungal “azole” drug discussed in class. [blank3] *** e) What metal element are these drugs attracted to in the active sites of fungal enzymes (hint: and also P450s)? [blank4] *** f)  Consider the portion of the biosynthesis pathway for a key component of the fungal membrane … What type of enzyme is responsible for this reaction?  [blank5] *** g) Would the reaction shown above be classified as a Phase I or Phase II type reaction?
