In vitro activity: In vitro, FH1(BRD-K4477) enhances hepatocyte functions, and promotes the maturation of well-differentiated cultures of iHeps, which potentially alleviates a major obstacle to the use of iPS cells as a renewable source of functional human hepatocytes.

Cell Assay: FH1 can promote differentiation of iPS-derived hepatocytes towards a more mature phenotype. It doubles albumin secretion during the differentiation of iPS cells into iHeps. Cultures treated with FH1 contain larger colonies of iHeps were with more pronounced hepatocyte morphologies. Moreover, treatment of FH1 also resulted in the increase of CYP3A4 levels and the decrease of AFP secretion .
