TP0480066 (compound 32) (0-2048 μg/mL; 18-24 h) demonstrats favorable antimicrobial activities against various bacterial species including some clinically isolated drug-resistant strains : MRSA (n=24), gPRSP (n=30), and VRE (n=34)[1].
TP0480066 (0-2048 μg/mL; 18-24 h) shows good antibacterial activity against Clostridioides difficile[1].
TP0480066 (0-2048 μg/mL; 24-48 h) demonstrates potent antibacterial activity to N. gonorrhoeae, including strains with decreased susceptibility or resistance to currently available antimicrobial agents[2].
TP0480066 (1.25×10-4, 5×10-4 and 2×10-3 µg/mL; 24 h) shows good time-kill activity when concentration up to (or more than) MIC (5×10-4 µg/mL) in N. gonorrhoeae ATCC 49226[2].
