Hinokitiol, a constituent of the wood of Chamaecyparis taiwanensis, was found to induce differentiation of teratocarcinoma F9 cells. When examined by the agar-overlay method, in which expression of plasminogen activator as a differentiation marker protein was detected, this compound exhibited a dose- and time-dependent induction. Induction of differentiation by hinokitiol occurred irreversibly and required its addition for more than 12h. Among its structure-related compounds tested, tropolone and two colchicine-related compounds exerted potent activities comparable to that of hinokitiol. These findings indicate that free tropolone structure in the molecules plays an essential role in inducing differentiation of F9 cells. Hinokitiol showed a strong inhibitory effect of DNA synthesis in very early stages of culture, suggesting that this effect may be responsible for triggering differentiation of F9 cells.

The effects of several chelators, including hinokitiol, on embryonal carcinoma F9 cell differentiation were assessed by assaying the production of plasminogen activator (PA) as a differentiation marker protein. Hinokitiol and tropolone which were potent differentiation inducers lost their activity following preincubation with Fe2+ and Fe3+ ions. Other metal ions had no or little effect on the hinokitiol-induced differentiation. Of several chelators examined, dithizone induced differentiation as effectively as did hinokitiol and tropolone. Dithizone-induced differentiation was also inhibited by preincubation with Fe3+ ions. It was concluded that some potent iron chelators could trigger the teratocarcinoma F9 cells to differentiate through the chelation with intracellular iron ions.
