体外研究 (In Vitro) | 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 againstClostridioides difficile[1]. TP0480066 (0-2048 μg/mL; 24-48 h) demonstrates potent antibacterial activity toN. gonorrhoeae, including strains with decreased susceptibility or resistance to currently available antimicrobial agents[2]. TP0480066 (1.25×10-4, 5×10-4and 2×10-3μg/mL; 24 h) shows good time-kill activity when concentration up to (or more than) MIC (5×10-4μg/mL) inN. gonorrhoeaeATCC 49226[2].
