Biology:Pilabactam

From HandWiki

Pilabactam is an beta-lactamase inhibitor that is being evaluated by Antabio as an antiinfective.[1][2][3]

Chemistry

The first in class non-β-lactam β-lactamase inhibitor avibactam contains a strained urea functional group within the diazabicyclooctane (DBO) ring system. This strained urea acts as a warhead that reacts with the active site serine residue in β-lactamases. Other drugs in this class include relebactam, durlobactam, nacubactam and zidebactam.[2] However none of these are active against carbapenem-resistant Acinetobacter baumannii. (CRAB). Pilabactam contains a fluorine atom that replaces a carboxamide group in the other DBOs and restores CRAB sensitivity.[2]
