MDM-2/p53 MDM2 Inhibitor

Nutlin-3a (Rebemadlin), an active enantiomer of Nutlin-3, is a potent murine double minute (MDM2) inhibitor (IC₅₀=90 nM). Nutlin-3a inhibits MDM2-p53 interactions and stabilizes the p53 protein, and induces cell autophagy and apoptosis. Nutlin-3a has the potential for the study of TP53 wild-type ovarian carcinomas.

Nutlin-3 is a commercial available p53-MDM2 inhibitor, with K_i of 90 nM.

Idasanutlin (RG7388) is an orally bioavailable MDM2 inhibitor with an IC₅₀ of 6 nM. Idasanutlin disrupts MDM2-p53 binding, stabilizes and activates p53, triggering cell cycle arrest, apoptosis, and reduced cancer cell viability. Idasanutlin reduces EGFR protein expression and phosphorylation, suppresses downstream SHP2, MEK1/2, ERK1/2, AKT, mTOR, p70(S6K1), and S6 signaling. Idasanutlin induces mitochondrial ROS production, drives p38 MAPK phosphorylation, upregulates NOXA, and mediates caspase-3-dependent apoptosis and gasdermin E-mediated pyroptosis. Idasanutlin can be used for the research of TP53-mutant non-small cell lung cancer, T-cell acute lymphoblastic leukemia, colorectal carcinoma, melanoma, diffuse large B-cell lymphoma, mantle cell lymphoma, non-Hodgkin lymphoma, severe fever with thrombocytopenia syndrome, neuroblastoma, acute lymphoblastic leukemia, relapsed or refractory acute myeloid leukemia, osteosarcoma, solid tumors, and hematological tumors.

Navtemadlin (AMG 232) is a potent, selective and orally available inhibitor of p53-MDM2 interaction, with an IC₅₀ of 0.6 nM. Navtemadlin binds to MDM2 with a K_d of 0.045 nM.

Siremadlin (NVP-HDM201) is a potent, orally bioavailable and highly specific p53-MDM2 interaction inhibitor.

MD-224 is a first-in-class and highly potent small-molecule human murine double minute 2 (MDM2) degrader based on the proteolysistargeting chimera (PROTAC) concept. MD-224 consists of ligands for Cereblon and MDM2. MD-224 induces rapid degradation of MDM2 at concentrations <1 nM in human leukemia cells, and achieves an IC₅₀ value of 1.5 nM in inhibition of growth of RS4;11 cells. MD-224 has the potential to be a new class of anticancer agent. MD-224 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Brigimadlin (BI 907828) is an orally active E3 ubiquitin-protein ligase MDM-2 inhibitor, preventing MDM-2 from negatively regulating the tumor suppressor p53. Brigimadlin can be used for antineoplastic research.

Alrizomadlin (APG-115) is an orally active MDM2 protein inhibitor binding to MDM2 protein with IC₅₀ and K_i values of 3.8 nM and 1 nM, respectively. Alrizomadlin blocks the interaction of MDM2 and p53 and induces cell-cycle arrest and apoptosis in a p53-dependent manner.

Milademetan (DS-3032) is a specific and orally active MDM2 inhibitor for the research of acute myeloid leukemia (AML) or solid tumors. Milademetan (DS-3032) induces G1 cell cycle arrest, senescence and apoptosis.

RG7112 is a potent, selective, orally active and blood-brain barrier crossed MDM2-p53 inhibitor, with an IC₅₀ of 18 nM and a K_D of 11 nM for binding to MDM2.

Serdemetan (JNJ-26854165) is a potent anticancer agent with radiosensitizing activity. Serdemetan exhibits antiproliferative activity in various p53 wild-type tumor cells. Serdemetan also antagonizes the Mdm2-HIF1α axis leading to decreased levels of glycolytic enzymes.

Solasodine (Purapuridine) is a steroidal alkaloid that occurs in plants of the Solanaceae family. Solasodine induces apoptosis by inhibiting the p53-MDM2 complex, p21Waf1/Cip1, and Bcl-2 proteins. Solasodine has neuroprotective, antifungal, hypotensive, anticancer, antiatherosclerotic, antiandrogenic and anti-inflammatory activities.

SP-141 is a specific inhibitor of MDM2. SP-141 promotes MDM2 auto-ubiquitination and degradation. SP-141 might be used for the research of pancreatic cancer and breast cancer cells.

MX69 is an inhibitor of MDM2/XIAP, used for cancer treatment.

Nutlin-3b, the inactive form of Nutlin-3 (HY-50696), is a p53/MDM2 inhibitor with an IC₅₀ of 13.6 μM. Nutlin-3b is 150 times less potent in binding to MDM2 than Nutlin-3a (HY-10029). Nutlin-3b is promising for research of cancers.

SAR405838 (MI-77301), an analog of MI-773, is a highly potent and selective MDM2-p53 interaction inhibitor. SAR405838 binds to MDM2 with a K_i of 0.88 nM. SAR405838 induces apoptosis and has potent antitumor activity.
