Question:
Which of the drug is represented by following structure?
Which of the drug is represented by following structure?
Show Hint
Look for the Sulfur group ($S-CO-CH_{3}$) at position 7 for Spironolactone.
Updated On: May 28, 2026
- Spironolactone
- Canrenone
- Aldesterone
- Eplerenone
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
The chemical structure identifies a specific steroid-based diuretic drug.
Step 2: Meaning
The structure shows a steroidal nucleus with a lactone ring at the 17-position and a thioacetate group ($-S-CO-CH_{3}$) at the 7-alpha position.
Step 3: Analysis
Spironolactone is characterized by the presence of this 7-alpha acetylthio group. Canrenone lacks the thioacetate; Aldosterone is the natural hormone; Eplerenone has an epoxy group.
Step 4: Conclusion
The structure matches Spironolactone.
Final Answer: (A)
