Description
MI-63 is a potent, specific, non-peptide inhibitor of the MDM2-p53 interaction.
Uses
MI 63 is an activator for p53, by targeting the MDM2 (Ki is 3 nM). MI 63 inhibits the proliferation of embryonic and alveolar rhabdomyosarcoma (ERMS and ARMS) cells (IC50 is 0.58 μM in RH36 cells), and induces apoptosis in ERMS and ARMS[1].
Definition
ChEBI: MI-63 is an azaspiro compound resulting from the formal fusion of position 3 of 6-chloro-oxindole with position 3 of (2R,3SS5S)-3-(3-chloro-2-fluorophenyl)-5-(2,2-dimethylpropyl)-N-[2-(morpholin-4-yl)ethyl]pyrrolidine-2-carboxamide. It is a potent inhibitor of the MDM2-p53 interaction. It has a role as an apoptosis inducer. It is an azaspiro compound, a member of morpholines, a member of oxindoles, a member of pyrrolidines, a member of monochlorobenzenes, a member of monofluorobenzenes and a secondary carboxamide.
