ICCB280 is a potent inducer of C/EBPα. ICCB280 exhibits anti-leukemic properties including terminal differentiation, proliferation arrest, and apoptosis through activation of C/EBPα and affecting its downstream targets (such as C/EBPε, G-CSFR and c-Myc).

How to use

In Vitro:

ICCB280 (0.1-50 μM; 48 h) suppresses the HL-60 cell growth, with an IC50 of 8.6 μM. ICCB280 (10 μM; 2-8 d) increases the C/EBPα expression (mRNA and protein) and modulates its target genes in HL-60 cells. ICCB280 (10 μM; 7 d) induces granulocytic differentiation and subsequent apoptosis in HL-60 cells.
