Abstract
A new hypothesis regarding the effect of vitamin K-3 On hepatoma cell growth is presented. In brief, exploration of cell growth activity has been identified with the action of p34(cdc2) kinase and its associate d protein tyrosine phosphatase. After exploring a series of substitute d derivatives of vitamin K and vitamin K-3 oxide, we suggest a mechani sm involving alkylation at the active-site cysteine for the inhibition of the protein tyrosine phosphatase which controls the activity of th e p34(cdc2) kinase.
