Abstract
New chemotherapeutics are needed to treat hepatocellular carcinoma (HCC), and menaquinones, homologs of vitamin K consisting of a 1,4-naphthoquinone core and a (poly)isoprene chain, are potential candidates. In this study, we designed and synthesized a series of phthalazine-1,4-dione-based menaquinone analogs. Among them, compounds bearing the intact isoprene chain exhibited selective antiproliferative activity towards HCC cell line JHH7, as compared with normal hepatocytes. The geranyl derivative 10 showed submicromolar potency, and might be a promising lead compound for anticancer agents.
