6β-[(N-phenylacetyl-glycyl)-amino]-penicillanic acid, also known as ampicillin, is a semi-synthetic antibiotic derived from the penicillin group. It is a broad-spectrum beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins, ultimately leading to bacterial cell lysis and death. Ampicillin is effective against a wide range of Gram-positive and some Gram-negative bacteria, making it useful for treating various infections such as respiratory, urinary tract, and skin infections. Its chemical structure features a phenylacetyl-glycyl side chain attached to the 6β position of the penicillanic acid nucleus, which contributes to its enhanced activity against certain bacteria compared to natural penicillins.
