Question

Which of the following antibiotics possesses a $\beta$-lactam ring in its structure?

• A. Erythromycin
• B. Vancomycin
• C. Ciprofloxacin
• D. Amoxicillin

Hint:

The $\beta$-lactam ring in antibiotics like Amoxicillin is the target of bacterial resistance mechanisms, such as $\beta$-lactamase enzymes.

Answer 1

The Correct Option is D

A $\beta$-lactam ring is a four-membered lactam ring in the structure of certain antibiotics, which inhibits bacterial cell wall synthesis. Amoxicillin, a penicillin-class antibiotic, contains a $\beta$-lactam ring in its structure, making it effective against a wide range of bacteria. Erythromycin (a macrolide), Vancomycin (a glycopeptide), and Ciprofloxacin (a fluoroquinolone) do not have a $\beta$-lactam ring in their structures.
Thus, the correct answer is Amoxicillin.
