SPOP-IN-2 (compound E1) is a Speckle-type POZ protein (SPOP) inhibitor with IC50 of 0.58 μM, which disrupt the SPOP-subtrate interaction and selectively inhibits proliferation of ccRCC.
SPOP-IN-2 (0-40 μM) binds to SPOPMATH protein through competition with puc-SBC1 peptide, disrupts the interaction between SPOPMATH and Myc-PTEN or Myc-DUSP7[1].SPOP-IN-2 (0-50 μM) selectively inhibits the colony formation of ccRCC in cell lines OS-RC-2, 786-O, A498, and 769-P[1].
