Biological Activity
Tigecycline hydrochloride (GAR-936 hydrochloride) is a broad-spectrum glycylcycline antibiotic. The mean inhibitory concentration (MIC) of Tigecycline against E. coli (strain MG1655) is approximately 125 ng/mL. The MIC50 and MIC90 for Acinetobacter baumannii (A. baumannii) were 1 and 2 mg/L, respectively.
in vitro
Tigecycline (0.63-30 μM, preincubated for 4 days, treated for 72 h) inhibits AML2 cells and HL-60 cells with IC
50 s of 4.72±0.54 and 3.06±0.85 μM (freshly prepared).
in vivo
Tigecycline (50 mg/kg; intraperitoneal injection; twice a day; for 11 days) reduces tumor volume and weight in NOD/SCID mice.
target
Mean MIC: 125 ng/mL ( E. coli )
MIC50: 1 mg/mL ( A. baumannii )
MIC90: 2 mg/mL ( A. baumannii )
