Several myrcenylhydroquinone derivatives have been evaluated for their cytotoxic activity against three neoplastic cell line cultures and compared with the activity previously observed on other neoplastic systems. Also a new series of this type of compounds has been prepared and the compounds synthesised have been evaluated by their GI(50) values.
