NCIt definition : The indanyl ester of carbenicillin, a broad-spectrum, semisynthetic penicillin derivative
with antibacterial activity. Following absorption, carbenicillin indanyl is rapidly
hydrolyzed to the active carbenicillin, which binds to and inactivates penicillin-binding
proteins (PBPs) located on the inner membrane of the bacterial cell wall, thereby
preventing the cross-linkage of peptidoglycans, which are critical components of the
bacterial cell wall. This leads to a weakening of the bacterial cell wall, eventually
causing bacterial cell lysis.;
