Antimicrobial agent-34 (compound 4h), characterized by its clogP value of 9.14, effectively disrupts the integrity of bacterial cell membranes. This compound boasts a minimum inhibitory concentration (MIC) ranging from 1-4 µg/mL and shows notable plasma stability with an HC50 of 131.1 µg/mL. Additionally, it exhibits excellent membrane selectivity, as evidenced by its HC50/MIC ratio of 65.6, and possesses rapid sterilization capabilities. It not only increases intracellular reactive oxygen species but also causes the leakage of protein and DNA, culminating in bacterial death. Antimicrobial agent-34 has demonstrated significant antibacterial effectiveness in vivo, particularly in a mouse sepsis model infected with Staphylococcus aureus ATCC43300.
