Background: Artepillin C (3,5-diprenyl-4-hydroxycinnamic acid) is the main bioactive component of
Brazilian green propolis, and possesses, among other things, anticancer properties. However, to the best of our
knowledge, there are no studies of artepillin C in cervical cancer.
Method: To explore a new therapeutic candidate for cervical cancer, we have evaluated the effects of artepillin
C on cellular viability in a comprehensive panel of human cervical cancer-derived cell lines including HeLa
(human papillomavirus/HPV 18-positive), SiHa (HPV 16-positive), CaSki (HPV 16- and 18-positive) and C33A
(HPV-negative) cells compared to a spontaneously immortalized human epithelial cell line (HaCaT).
Results: Our results demonstrated that artepillin C had a selective effect on cellular viability and could induce
apoptosis possibly by intrinsic pathway, likely a result of oxidative stress, in all cancer-derived cell lines but not
in HaCaT. Additionally, artepillin C was able to inhibit the migration and invasion of cancer cells.
Conclusion: Thus, artepillin C appears to be a promising new candidate as an anticancer drug for cervical cancer
induced by different HPV types.
