Which of the following drugs has a 1,3,4-thiadiazole ring system?
Show Hint
- The 1,3,4-thiadiazole ring is commonly found in drugs with carbonic anhydrase inhibition properties, like Acetazolamide.
- Recognizing key heterocyclic rings like thiadiazole helps in identifying specific drug classes.
- Dichlorophenamide
- Spironolactone
- Acetazolamide
- Furosemide
The Correct Option is C
Solution and Explanation
The 1,3,4-thiadiazole ring is a heterocyclic compound containing both sulfur and nitrogen atoms, and it is found in certain pharmacologically active compounds. Among the options:
- Acetazolamide (option C) contains a 1,3,4-thiadiazole ring in its structure. Acetazolamide is a carbonic anhydrase inhibitor, primarily used in the treatment of glaucoma, edema, and certain types of seizures. The thiadiazole ring is integral to its pharmacological activity.
Why Other Options Are Incorrect:
- (A) Dichlorophenamide: This drug does not contain the 1,3,4-thiadiazole ring system.
- (B) Spironolactone: This drug contains a lactone ring system, but not a thiadiazole ring.
- (D) Furosemide: Furosemide contains a sulfonamide group and a benzene ring, but it does not have a thiadiazole ring.
Thus, the correct drug with the 1,3,4-thiadiazole ring system is Acetazolamide.
