Salubrinal

Salubrinal is a selective inhibitor of eIF2α dephosphorylation and inhibits ER stress-mediated apoptosis with EC50 of ~15 μM in a cell-free assay.

S7369

4EGI-1

4EGI-1 is a competitive eIF4E/eIF4G interaction inhibitor by binding to eIF4E with KD of 25 μM. 4EGI-1 specifically inhibits the function of mTOR by blocking the activation of 4E-BP1. 4EGI-1 induces apoptosis.

S7437

Sal003

Sal003 is a potent and cell-permeable eIF-2α phosphatase inhibitor.

S0706New

ISRIB

ISRIB is an integrated stress response (ISR) inhibitor that potently reverses the effects of eukaryotic initiation factor 2α (eIF2α) phosphorylation with IC50 of 5 nM.

S6533

Briciclib

Briciclib (ON-014185) is a water soluble derivative of ON-013100, a small molecule that binds to and inhibits eukaryotic translation initiation factor 4E (eIF4E).

S7428New

Rocaglamide

Rocaglamide (Roc-A), isolated from Aglaia species, is a potent inhibitor of heat shock factor 1 (HSF1) activation with IC50 of ~50 nM for HSF1. Rocaglamide inhibits the function of the translation initiation factor eIF4A. Rocaglamide also inhibits NF-κB activity. Rocaglamide exhibits anti-tumor activity.

S2961New

GC7 Sulfate

GC7 (N1-guanyl-1,7-diaminoheptane) Sulfate is an inhibitor of deoxyhypusine synthase (DHPS). GC7 inhibits Neuroblastoma (NB) cell proliferation in a dose-dependent manner, through induction of the cell cycle inhibitor p21 and reduction of total and phosphorylated Rb proteins.

S9668New

PKR-IN-C16

PKR-IN-C16 (imoxin, C16, Imidazolo-oxindole PKR inhibitor C16) is a specific inhibitor of RNA-dependent protein kinase (PKR, Protein Kinase R, EIF2AK2). PKR-IN-C16 prevents apoptosis and IL-1β production in an acute excitotoxic rat model with a neuroinflammatory component.

S7370

4E1RCat

4E1RCat is a dual inhibitor of eIF4E:eIF4G and eIF4E:4E-BP1 interaction, and inhibits the binding of eIF4G to eIF4E with IC50 of 3.2 μM.

S8275

Tomivosertib (eFT-508)

Tomivosertib (eFT-508) is a potent and selective MNK1/2 inhibitor with IC50s of 2.4 nM and 1 nM, respectively. It potentially results in decreased tumor cell proliferation and tumor growth. Tomivosertib (eFT-508) inhibits eIF4E phosphorylation and dramatically downregulates PD-L1 protein abundance.

S8181

SBI-0640756

SBI-0640756 is a first-in-class inhibitor that targets eIF4G1 and disrupts the eIF4F complex. It can also suppress AKT and NF-kB signaling.
