(5S,6S)-6-[(R)acetooxyeth-2-yl]-penem-3-carboxylatepropane

(5S,6S)-6-[(R)acetooxyeth-2-yl]-penem-3-carboxylatepropane is a synthetic penem derivative. Penems are a subclass of beta-lactam antibiotics structurally related to carbapenems and penicillins. They act by inhibiting bacterial cell wall synthesis through binding to penicillin-binding proteins (PBPs), leading to bactericidal activity against susceptible bacteria. This compound features a penem core with specific stereochemistry at positions 5 and 6 and an acetooxyethyl side chain at position 6, as well as a carboxylic acid group at position 3. The detailed pharmacological properties, clinical indications, or commercial development status for this specific molecule are not available in the provided sources; however, it is structurally consistent with experimental or investigational antibacterial agents within the penem class[7][3][1].
