Product Description
ARCC-4 is a nanomolar androgen receptor (AR) degrader based on PROTAC technology with a D50 of 5 nM. ARCC-4 is an enzalutamide-based von Hippel-Lindau (VHL)-recruiting AR PROTAC. ARCC-4 effectively degrades AR mutations relevant to antiandrogen studies.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
The three-promoted polymer complex binds more readily when ARCC-4 improves the protein-protein reaction between AR and VHL [1]. AR can be efficiently degraded by -4 (0.1-10,000 nM; 20 hours), with a D50 of 5 nM and a Dmax of greater than 95% [1]. Molds with ARCC-4 (100 nM; 12 hours) exhibit AR. ARCC-4 does not impede PR-A or PR-B, but it nearly solely modulates AR through chromoplast pigments [1]. Clinically significant AR mutations are effectively suppressed by ARCC-4 [1]. ARCC-4 is still functional in the presence of high androgen levels [1].

Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
