TAS4464
Based on 10 publication(s) in Google Scholar
TAS4464 is a long-acting, highly selective covalent inhibitor targeting NEDD8-activating enzyme (NAE) (IC50=0.955 nM), and also inhibits CAII with an IC50 of 0.73 μM, which is less potent than MLN4924 (HY-70062). The IC50 values of TAS4464 against other E1 enzymes UAE and SAE are 449 nM and 1280 nM, respectively. TAS4464 targets NEDD8 in an ATP-dependent manner to inhibit NAE, blocks the neddylation pathway, causes accumulation of CRL ubiquitin ligase substrates (such as CDT1, p27, phosphorylated IκBα), and further induces tumor cell apoptosis. TAS4464 exhibits antiproliferative and cytotoxic effects, and has broad-spectrum antitumor activity against various hematologic and solid tumor cell lines as well as patient-derived tumor cells. TAS4464 has a wide selcetive window, without obvious toxicity. TAS4464 can be used in the research of hematologic malignancies (leukemia, lymphoma, multiple myeloma, etc.) and solid tumors (small cell lung cancer, colorectal cancer, sarcoma, endometrial cancer, ovarian cancer, etc.).

Biological Activity
IC50：0.955 nM (NAE)[1]
TAS4464 is a highly potent and selective recombinant NAE inhibitor, with over 470-fold and 1340-fold selectivity against recombinant UAE and SAE, respectively, and weak off-target inhibitory activity against CA2[1].
TAS4464 (1-10 μM; 24-48 h) induces apoptosis in leukemia, lymphoma, multiple myeloma and solid tumor cell lines, with the apoptosis rate increasing as the drug concentration rises[1].
TAS4464 (1 nM-1 μM, 4 h; 100 nM, 1-24 h) significantly increases the protein expression levels of CRL ubiquitin ligase substrates CDT1, p27, and phosphorylated IκBα in tumor cells, while reduces the level of cullin neddylation modification[1].
TAS4464 (0.1-10 μM; 24-48 h) significantly inhibits the migratory capacity of solid tumor cell lines such as colorectal cancer and sarcoma, with a concentration-dependent inhibitory effect[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
TAS4464 (100 mg/kg; i.v.; administered on days 1, 4, 8 and 11, with one cycle every 21 days; 8 cycles total) hydrochloride significantly prolongs survival and reduces tumor burden in a systemic diffuse large B-cell lymphoma model of SCID mice xenografted with TMD8-Luc[1].
