Cyclooxygenase is an enzyme the catalyzes the first reaction in the biosynthesis of prostaglandins. Prostaglandins are small molecules that can trigger inflammation. Aspirin is an effective anti-inflammatory agent because it will form a covalent bond with an amino acid found in the active site of cyclooxygenase to inhibit the enzymes activity. New cyclooxygenase must be synthesized before prostaglandin synthesis can continue. Based on this description, aspirin is an example of a competitive reversible inhibitor.

By using an NSAID to reduce inflammation, what other physiological processes may be affected by blocking prostaglandin synthesis?

A patient came to the hospital with severe chest pain and was diagnosed as a case of angina. One of the drug he was given was aspirin which inhibit platelets aggregation. Prostaglandin which promotes platelet aggregation is:Select one:a. Thrombaxaneb. PGE2c. Prostacyclind. PGF2α

Name the inhibition where the end product of the biosynthetic pathway inhibits the activity of the first enzyme.  Competitive inhibition   Feedback repression   Feedback inhibition   Noncompetitive inhibition   Allosteric inhibition

Compare prostaglandins to leukotrienes. Select the answer which most accurately matches your own.Leukotrienes are formed by the enzyme lipooxygenase whereas prostaglandins are formed by the enzyme cyclooxygenase. They both mediate pain but leukotrienes attract leukocytes to the area and prostaglandins dilate blood vessels.Leukotrienes are formed by the enzyme cyclooxygenase whereas prostaglandins are formed by the enzyme lipooxygenase.

Aspirin (acetylsalicylic acid) is a well-known pain reliever and anti-inflammatory drug. However, it can cause stomach irritation in some individuals. Acetaminophen, another common pain reliever, is gentler on the stomach but lacks the anti-inflammatory properties of aspirin. Here's a challenge that combines organic chemistry concepts!The Task: Develop a two-step synthesis plan to convert aspirin (acetylsalicylic acid) into acetaminophen (N-acetyl-p-aminophenol).Clues and Considerations:Aspirin has an ester functional group (carbonyl bonded to an oxygen and then an alkyl group).Acetaminophen has an amide functional group (carbonyl bonded to a nitrogen and then a carbon).Both molecules share a similar aromatic ring structure with a hydroxyl group (-OH) attached.Possible Steps:Step 1: What kind of reaction could be used to break the ester bond in aspirin?Step 2: How can the resulting intermediate be transformed into an amide group to yield acetaminophen?Bonus Challenge:Identify the reagents required for each step of your proposed synthesis.
