7-Hydroxystaurosporine (UCN-01) is a protein kinase inhibitor which is under development as an anti-cancer agent in the USA and Japan. Although UCN-01 was originally isolated from the culture broth of Streptomyces sp. as a protein kinase C-selective inhibitor, its ultimate target as an anti-cancer agent remains elusive. As a single agent, UCN-01 exhibits two key biochemical effects, namely accumulation of cells in the G1 phase of the cell cycle and induction of apoptosis. Both these effects may be important for its anti-cancer activity. As a modulator, 7-Hydroxystaurosporine enhances the cytotoxicity of other anti-cancer drugs such as DNA-damaging agents and anti-metabolite drugs through putative abrogation of G2 and/or S phase accumulation induced by these anti-cancer agents. 7-Hydroxystaurosporine had been in phase II clinical trials Life Sciences for the treatment of T-cell lymphoma, malignant melanoma, pancreatic cancer, small cell lung cancer, acute myeloid leukemia, ovarian cancer. However, the research was either discontinued or suspended.

The three different human HCC cell lines (HepG2, Hep3B, and Huh7) were grown at 37°C in the presence of 5% CO2 in Dulbecco's modified Eagle's media (DMEM) supplemented with 10% foetal bovine serum (FBS). The cells were seeded in a 96-well dish to a final concentration of 1×10^4 cells/well and incubated in DMEM containing 10% FCS overnight. After incubation with different concentrations of the tested compounds (7-Hydroxystaurosporine) for 72 h, the cells were incubated for 2 h with DMEM containing 0.4 mg/ml MTT. The conversion of MTT to formazan in metabolically viable cells was measured at 490 nm absorbance in a 96-well microtiter plate reader.
