A
Vancomycin
B
Penicillin
C
Ciprofloxacin
D
Erythromycin
Verified step by step guidance1
Understand that beta-lactam antibiotics are characterized by the presence of a beta-lactam ring in their chemical structure, which is crucial for their mechanism of action.
Recall that beta-lactam antibiotics work by inhibiting bacterial cell wall synthesis, specifically targeting penicillin-binding proteins (PBPs).
Identify the drugs listed: Vancomycin, Penicillin, Ciprofloxacin, and Erythromycin, and consider their antibiotic classes.
Recognize that Penicillin belongs to the beta-lactam class because it contains the beta-lactam ring and inhibits cell wall synthesis.
Note that Vancomycin is a glycopeptide antibiotic, Ciprofloxacin is a fluoroquinolone, and Erythromycin is a macrolide, none of which have the beta-lactam ring.
