(+)-JJ-450 is a non-competitive antagonist targeting the androgen receptor (AR) that inhibits AR nuclear localization and transcriptional activity in the absence of androgen. (+)-JJ-450 is less active than (-)-JJ-450 in inhibiting prostate-specific antigen (PSA) expression in LN95 cells, possibly because (+)-JJ-450 targets the ligand binding domain (LBD) of AR. (+)-JJ-450 inhibits the transcriptional activity of AR and its splice variants (e.g., ARv7) by promoting the degradation of unliganded AR in the nucleus and reducing the binding of AR to androgen response elements (AREs). (+)-JJ-450 can be used in castration-resistant prostate cancer (CRPC) studies that are resistant to enzalutamide (MDV3100).

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
