Abstract

Jaceosidin (4',5,7-trihydroxy-3',6-dimethoxyflavone) was isolated from Artemisia argyi as a putative oncogene inhibitor. Jaceosidin inhibited binding between oncoprotein E6 of the human papillomavirus and the p53 tumor suppressor protein. In addition, jaceosidin inhibited binding between the E7 oncoprotein and the Rb tumor suppressor protein, and also inhibited the function of HPV-16 harboring cervical cancer cells, including SiHa and CaSki. Collectively, jaceosidin inhibited the functions of the E6 and E7 oncoproteins of the human papillomavirus, suggesting that this compound might be used as a potential drug for the treatment of cervical cancers associated with the human papillomavirus.
