SK33 Chemical Properties,Uses,Production

Uses

SK33, a trifluoromethylated enobosarm analog, is a potent, and tissue selective anti-androgen. SK33reduces androgen receptor (AR) transcriptional activity[1].

Biological Activity

SK33, a trifluoromethylated enobosarm analog, is a potent, and tissue selective anti-androgen. SK33reduces androgen receptor (AR) transcriptional activity[1]. In LNCaPAR+ cells, SK33, demonstrates a significantly potent activity with IC50=0.2 μM. SK33 decreases cells entering S-phase in LNCaP cells. Treatment of LNCaP/BicR cells with increasing concentrations of SK33 for 96 hours results in a dose-dependent response and an inhibition of cell growth, with IC50 of approximately 5 μM for SK33[1]. SK33 (50 mg/kg; s.c.; 24 hours) inhibits AR transcriptional activity[1].

in vivo

SK33 (50 mg/kg; s.c.; 24 hours) inhibits AR transcriptional activity[1].

Animal Model:ARE-Luc mice[1]
Dosage:50 mg/kg
Administration:Subcutaneously; 24 hours
Result:Inhibited AR transcriptional activity.
