L-778123 alone does not have obvious cytotoxicity on HT-29 and A549 cell lines (IC50: >100 μM), but can generate synergistic effects with Doxorubicin (HY-15142A), with the decreased IC50s of 1.72 and 1.52 μM respectively[2].
L-778123 inhibits myeloid leukemia cell proliferation with IC50 values of 0.2 μM-1.8 μM for cell lines, and 0.1 μM-161.8 μM in primary samples[3].
L-778123 (0-1 μM, 12 h; or 5 μM, 6 h) inhibits H-RAS prenylation in HL-60 cells, and inhibits phosphorylated MEK-1/2 level (5 μM, 24 h)[3].
L-778123 (0-100 μM, 72 h) inhibits lymphocyte activation (marker: CD71 or CD25) and function in human PBMCs[4].
