E1/E2/E3 Enzyme
E1 activating enzyme; E2 conjugating enzyme; E3 ligating enzyme; Ubiquitin activating enzyme; Ubiquitin conjugating enzyme; Ubiquitin ligase
Ubiquitin (UB) is a protein modifier that regulates many essential cellular processes. To initiate protein modification by UB, the E1 enzyme activates the C-terminal carboxylate of UB to launch its transfer through the E1-E2-E3 cascade onto target proteins. The E1 enzyme is the activating enzyme, to which ubiquitin is attached in an ATP-dependent reaction by a thioester bond. The E2 enzyme is the conjugating enzyme, to which the ubiquitin is transferred from the E1. The E3 is the ubiquitin ligase, which directly or indirectly catalyzes the transfer of the ubiquitin to the target protein (the substrate), with the formation of an isopeptide bond.

TAK-243
0 ImagesSynonyms: MLN7243TAK-243 (MLN7243) is a first-in-class, selective ubiquitin activating enzyme, UAE (UBA1) inhibitor (IC50=1 nM), which blocks ubiquitin conjugation, disrupting monoubiquitin signaling as well as global protein ubiquitination. TAK-243 (MLN7243) induces endoplasmic reticulum (ER) stress, abrogates NF-κB pathway activation and promotes apoptosis.
-
Nutlin-3a
0 ImagesSynonyms: RebemadlinNutlin-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.

Subasumstat
0 ImagesSynonyms: TAK-981Subasumstat (TAK-981) is a first in class and selective inhibitor of the SUMOylation enzymatic cascade, with potential immune-activating and antineoplastic activities.
-
Pentagalloylglucose
0 ImagesSynonyms: Penta-O-galloyl-β-D-glucose; 1,2,3,4,6-Pentagalloyl glucosePentagalloylglucose (Penta-O-galloyl-β-D-glucose) is an orally active gallic tannin compound and an inducer of apoptosis and autophagy. Pentagalloglucose induces cell apoptosis and autophagy through the GSK3β/β-catenin pathway. Pentagalloylglucose inhibits UBE2T-mediated p53 ubiquitination, upregulates p53, downregulates RRM1/RRM2 in pancreatic cancer organoids. Pentagalloglucose has antioxidant, anti mutagenic, anti-inflammatory, anticonvulsant, cardioprotective, anti allergic, cholesterol lowering, and anti-tumor activities.

Idasanutlin
0 ImagesSynonyms: RG7388Idasanutlin (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.

DI-1859
0 ImagesDI-1859 is a DCN1 and cullin 3 inhibitor with a Ki of <1 nM against human DCN1. DI-1859 forms a covalent bond with Cys115 of DCN1, cleaves its dimethylamino group, disrupts the DCN1-UBC12 interaction, and selectively inhibits the neddylation modification of cullin 3 relative to other cullins. DI-1859 inactivates CRL3, promotes the accumulation of NRF2 and SLC7A11, upregulates the expression of HO-1 and NQO1, reduces reactive oxygen species (ROS) levels, enhances insulin signaling, promotes insulin secretion, activates RhoA, regulates the phosphorylation of AKT, without completely blocking the neddylation modification of cullin 3 or restoring the expression of IRS-1. DI-1859 can be used in the research of Acetaminophen (HY-66005)-induced hepatotoxicity, hyperglycemia, metabolic dysfunction-associated steatotic liver disease, insulin resistance, breast cancer and lung cancer.
