Abstract :

HPV (Human Papillomavirus) is known as one of the papillomavirus family which is able to infect humans. HPV infection appears to be a necessary prerequisite for more than 90% of cervical cancer, especially squamous cell carcinoma. Although HPV vaccination was recommended in almost all developed countries, including JAPAN, very recently, serious adverse events were reported. Thus, anti-HPV agents should be developed in order to prevent many types of cervical cancers. However, since more than 120 types of HPVs have been identified, it is not easy to inhibit the tumor promoting activities of all carcinogenic HPVs. Last year, at this conference, the author reported some candidate compounds which can be HPV E6 protein inhibitors developed by using in silico screening, especially, docking studies. However, the obtained agents are not for anti-cancer drugs but for in vitro studies which can reveal whether E6 protein inhibitors are capable of suppressing canceration of HPV infected cells. Thus, in this study the author tried to develop other candidates of HPV E6 protein inhibitors which can be more druglike using in silico drug-like compounds database. Some lead chemical structures, which appeared to be effective not only for revealing the mechanism of canceration of HPV infected cells, but also for some key compounds of anti-HPV E6 inhibitors were obtained.
