Biological Activity

SC428 (SC-428) is a small molecule androgen receptor (AR) signaling inhibitor, directly binds to the AR N-terminal domain (NTD) and exhibits pan-AR inhibitory effect.
SC428 potently decreased the transactivation of AR-V7, ARv567es, as well as full-length AR (AR-FL) and its LBD mutants.
SC428 substantially suppressed androgen-stimulated AR-FL nuclear translocation, chromatin binding, and AR-regulated gene transcription.
SC428 significantly attenuated AR-V7–mediated AR signaling that does not rely on androgen, hampered AR-V7 nuclear localization, and disrupted AR-V7 homodimerization.
SC428 inhibited in vitro proliferation and in vivo tumor growth of cells that expressed a high level of AR-V7 and were unresponsive to enzalutamide (ENZ) treatment.
