Abstract
Due to the increase in cancer cases nowadays, an increase in studies related
to treatment has been observed. Although many natural or synthetic compounds have
been described as therapeutic today, the effects of these treatments are seen in both
healthy and cancer cells. In order to reduce these undesirable effects seen in
chemotherapy and radiotherapy, alternative treatments that have less effect on healthy
cells or alternative attitudes that will allow the minimum use of therapeutics in these
treatments continue to be investigated. In particular, such studies focus on natural
compounds with phenolic properties. This chapter focuses on the relationship between
coumarin derivatives, curcumin, Olea europaea leaf extract, and Cynara scolymus leaf
extract with hepatocellular carcinoma. Furthermore, the effect of these natural
compounds on the genetic hallmarks of various signalling pathways and important
cellular metabolism molecules of hepatocellular carcinoma are discussed.
