The KD values of D13-9001 in Escherichiacoli and Pseudomonas aeruginosa were 1.15μM and 3.57μM, respectively. D13-9001 has antibiotic activity. It is an effective AcrB (AcrAB-TolC efflux pump subunit) and MexB (MexAB-OprM efflux pump subunit) inhibitor.
G0507 is a pyrrolopyrimidinedione compound that serves as a potent inhibitor of Escherichiacoli growth, effectively inducing the extracytoplasmic σE stress response. It acts as a valuable chemical probe, specifically designed to dissect lipoprotein trafficking in Gram-negative bacteria. Notably, G0507 demonstrates strong inhibitory activity against the LolCDE ABC Transporter.
