Bioactivity

• In Vivo:
  In vivo treatment with RA-9 retards tumor growth, increases overall survival, and was well tolerated by the host.
• In Vitro:
  The characterization of RA-9 as a small-molecule inhibitor of proteasome-associated DUBs. Treatment with RA-9 selectively induces onset of apoptosis in ovarian cancer cell lines and primary cultures derived from donors. Loss of cell viability following RA-9 exposure is associated with an unfolded protein response as mechanism to compensate for unsustainable levels of proteotoxic stress.

• Animal Research:
  Mice were inoculated i.p. with 100,000 ES-2 cells (in 100 μl DMEM) stably expressing GFP. When tumor was detectable (approx. 6 days post inoculation), mice were randomly assigned into two groups receiving RA-9 or 0.9% saline. Treatment with RA-9 was given i.p. on a one-day on, two-days off schedule. The control group received the vehicle alone at the same schedule. Working concentrations of RA-9 (10 mg/ml) were reached by dissolution in Cremophor EL and polyethylene glycol 400 (Sigma). Prior to each injection RA-9 was further diluted in 0.9% saline (working concentration 1mg/ml). To monitor for tumor growth, RA-9 treated and control mice were imaged with an IVIS SpectrumCT Pre-clinical in vivo imaging system (PerkinElmer) every other day. Animals were sacrificed when abdomens became distended to twice normal size.
