描述 | Hydroxyflutamide (HF), an active metabolite of the first generation antiandrogen flutamide, was used in clinic to treat prostate cancer targeting androgen receptor (AR) [2]. Combined treatment with 5-FU and OH-flutamide (Hydroxyflutamide) had a synergistic effect on CDX25R cells. OH-flutamide decreased expression of the transcription factor E2F1, and subsequently of thymidylate synthase (TS), in CDX25R cells but not in AR-negative DU145 cells[3]. In the absence of dihydrotestosterone, concentrations of 10 mM M2 or hydroxyflutamide promote AR binding to androgen response element DNA and activation of transcription. Agonist activities of M2 and hydroxyflutamide occur at 10-fold lower concentrations with the mutant AR (Thr877 to Ala) endogenous to LNCaP human prostate cancer cells[4]. A significant decrease in sperm mitochondrial membrane potential and a concomitant increase in mitochondrial superoxide anion production after a 2-hour incubation with 50 μg OH-Flu (Hydroxyflutamide) compared with the respective controls and other doses used. The adverse effects of OH-Flu become strengthened over time. Hydroxyflutamide significantly decreased the fast sperm subpopulation percentage after 15 minutes and reduced the straight line velocity distribution[5]. Endometrial decidualization in ovariectomized, steroid-treated rats, following artificial stimuli, was significantly suppressed in hydroxyflutamide-treated rats compared with controls[6]. |
