Chitin synthase inhibitor 2 (compound 2b) is a potent inhibitor of chitin synthase with the IC50 value of 0.09 mM and the Ki value of 0.12 mM. Chitin synthase inhibitor 2 has antimicrobial activities in vitro and shows synergistic or additive effects with fluconazole or polyoxin B[1].
ATP synthase inhibitor 2 is a Pseudomonas aeruginosa (PA) ATP synthase inhibitor (IC50=10 μg/mL). ATP synthase inhibitor 2 can inhibit Pseudomonas aeruginosa (PA) ATP synthesis activity completely at 128 μg/mL[1].
