How to use

In Vitro:

ARD-266 (Compound 11; 100 nM; 1-24 hours; LNCaP and VCaP cells) treatment effectively reduces the AR protein level within 3 h and achieves near-complete AR elimination with a 6 h treatment in the LNCaP cells. ARD-266 (Compound 11; 1-10000 nM; 24 hours; LNCaP cells) treatment effectively suppresses the expression of PSA, TMPRSS2, and FKBP5 genes in a dosedependent manner and is capable of reducing the mRNA levels of PSA, TMPRSS2, and FKBP5 genes by >50% at 10 nM in the LNCaP cell line.
