Antimicrobial agent-34

Antimicrobial agent-34 (compound 4h) is an antibacterial agent (MIC = 1–4 μg/mL), with a clogP value of 9.14. Antimicrobial agent-34 has good plasma stability (HC50 of 131.1 μg/mL) and good membrane selectivity (HC50/MIC is 65.6), with rapid sterilization capability. Antimicrobial agent-34 destroys the integrity of bacterial cell membranes, induces an increase in intracellular reactive oxygen species, and leaks protein and DNA, ultimately leading to bacterial death. Antimicrobial agent-34 demonstrates significant in vivo antibacterial potency in a mouse sepsis model infected with Staphylococcus aureus ATCC43300[1].
