| Outline of Final Research Achievements |
After progression of CRPC during hormonal treatment and docetaxel treatment, we face difficulty of these treatments. Therefore, it is important to develop new medicines next to taxanes. Then we focused on one of flavonoids, 2’-hydroxyflavanone (2’-HF). 2’-HF inhibited not only cell proliferation of androgen-sensitive prostate cancer LNCaP but also androgen-independent prostate cancer cells PC-3 and DU145. We also examined effect of 2’-HF on androgen receptor (AR) activity. When LNCaP cells transfected with PSA promoter-driven luciferase reporter were treated with 2’-HF in the presence of androgen, AR activity was reduced by 2’-HF. These data indicate that 2’-HF is candidate to treat CRPC after docetaxel treatment.
