MI-1061 is a potent, orally bioavailable, and chemically stable MDM2 (MDM2-p53 interaction) inhibitor (IC50=4.4 nM; Ki=0.16 nM). MI-1061 potently activates p53, induces apoptosis, and has anti-tumor activity[1]. IC50: 4.4 nM (MDM2)[1]Ki: 0.16 nM (MDM2)
MI-1061 achieves IC50=100 and 250 nM in the SJSA-1 and HCT-116 p53+/+ cell lines, respectively, and has IC50>10000 nM in the p53 knockout cell line HCT-116 p53-/-cell line[1].
MI-1061 is capable of achieving tumor regression in the SJSA-1 xenograft tumor model in mice with oral administration[1].

Targeted Degradation of MDM2 as a New Approach to Improve the Efficacy of MDM2-p53 Inhibitors
J Med Chem 2019 Jan 24;62(2):445-447.PMID:30575392DOI:10.1021/acs.jmedchem.8b01945.
MDM2 is a key oncogenic protein that serves as a negative regulator of the tumor suppressor p53. While a number of inhibitors of the MDM2-p53 interaction have progressed to clinical testing as treatments for a variety of hematologic and solid tumor cancers, the results thus far have been mixed, with perhaps the strongest responses observed in relapsed/refractory acute myeloid leukemia (AML). In an effort to improve the efficacy for this class of compounds, researchers have turned to targeted degradation of MDM2. IMiD-based MDM2 PROTAC 8, which potently reduces MDM2 protein levels through targeted degradation, exhibits enhanced efficacy in the RS4;11 xenograft model relative to a nondegrading MDM2-p53 inhibitor MI-1061.
Design of chemically stable, potent, and efficacious MDM2 inhibitors that exploit the retro-mannich ring-opening-cyclization reaction mechanism in spiro-oxindoles
J Med Chem 2014 Dec 26;57(24):10486-98.PMID:25496041DOI:10.1021/jm501541j.
Inhibition of the MDM2-p53 protein-protein interaction is being actively pursued as a new anticancer therapeutic strategy, and spiro-oxindoles have been designed as a class of potent and efficacious small-molecule inhibitors of this interaction (MDM2 inhibitors). Our previous study showed that some of our first-generation spiro-oxindoles undergo a reversible ring-opening-cyclization reaction that, from a single compound in protic solution, results in an equilibrium mixture of four diastereoisomers. By exploiting the ring-opening-cyclization reaction mechanism, we have designed and synthesized a series of second-generation spiro-oxindoles with symmetrical pyrrolidine C2 substitution. These compounds undergo a rapid and irreversible conversion to a single, stable diastereoisomer. Our study has yielded compound 31 (MI-1061), which binds to MDM2 with Ki = 0.16 nM, shows excellent chemical stability, and achieves tumor regression in the SJSA-1 xenograft tumor model in mice.
