体外研究
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). Tigecycline inhibits AML2 cells and HL-60 cells with IC 50 s of 5.64±0.55 and 4.27±0.45 μM (1 day preincubation). Tigecycline inhibits AML2 cells and HL-60 cells with IC 50 s of 5.02±0.60 and 4.39±0.44 μM (2 day preincubation). Tigecycline inhibits AML2 cells and HL-60 cells with IC 50 s of 4.09±0.41 and 3.95±0.39 μM (3 day preincubation). After a 4 day preincubation of Tigecycline in saline, Tigecycline lost its ability to kill TEX human leukemia cells (from IC 50 ~5 µM when freshly prepared to IC 50 >50 µM after 4 days preincubation) as measured by CellTiter Flour assay.
Cell Viability Assay
Cell Line: Human leukemic OCI-AML2, HL-60 (ATCC) and TEX cell lines Concentration: 0.63-30 µM Incubation Time: Preincubated for 4 days, treated for 72 hours Result: Inhibited AML2 cells and HL-60 cells with IC 50 s of 4.72±0.54 and 3.06±0.85 μM (freshly prepared). -
