Biological Activity for SP 141

SP 141 is a high affinity MDM2 inhibitor (K_i = 28 nM); directly binds MDM2. SP 141 inhibits MDM2 expression and induces MDM2 autoubiquitination and proteasomal degradation. SP 141 attenuates growth of breast cancer xenograft tumors. SP 141 impairs liposarcoma growth in vitro and in human xenograft models. SP 141 is cell permeable.
