PERK-IN-3 is a potent inhibitor of PERK (IC50 of 7.4 nM).

GCN2-IN-6 is also a eIF2α kinase PERK inhibitor with an IC50 of 0.26 nM (in enzymatic assay) and 230 nM (in cells). GCN2-IN-6  is a potent, and orally available GCN2 inhibitor confirmed by in-house enzymatic (IC50 of 1.8 nM) and cellular assays (IC50 of 9

CCT020312 (0-9 µM, 24 h) treatment of medium HT29 cells for 24 h resulted in a concentration-dependent loss of P-S608-pRB signaling with linear response values between 1.8 and 6.1 µM.

ISRIB is a potent and selective PERK inhibitor.

ONO-8130 is an orally available antagonist of EP1 receptor.

GSK2606414 is a cell-permeable and orally active protein kinase R-like endoplasmic reticulum kinase(PERK)inhibitor with IC50 of 0.4 nM. GSK2606414 inhibits PERK activation in cells and suppresses the growth of human tumor xenografts in mice.

GSK2656157 is a highly specific and ATP-competitive PERK inhibitor (IC50: 0.9 nM) in a cell-free assay. The selectivty is 500-fold higher against a panel of 300 kinases.

ISRIB (trans-isomer) is a potent inhibitor of PERK (IC50=5 nM) that restores protein translation and prevents SG formation in the presence of P-eIF2α.

MK-28 is a selective PERK agonist that reduces toxicity and prolongs survival in a Huntington's disease model.MK-28 has a significant killing effect on MK28 gastric cancer cells.

(S)-PERK-IN-5, the S-enantiomer of PERK-IN-5, is a PERK inhibitor with an IC50 range of 0.101-0.250 μM.

PERK-IN-5 is a highly selective, potent, orally active inhibitor of protein kinase R-like endoplasmic reticulum (ER) kinase (PERK), displaying inhibition with IC50 values of 2 nM for PERK and 9 nM for p-eIF2α. PERK-IN-5 significantly inhibited tumor growth in the 786-O renal cell carcinoma xenograft tumor model.

Compound V8 (PERK/eIF2α activator 1), a flavonoid, exhibits anti-tumor properties by inducing apoptosis and activating the PERK-eIF2α-ATF4 pathway. It effectively inhibits the proliferation of HepG2 cells, with an IC 50 value of 23 μM [1].

GP 1a is a potent agonist of cannabinoid receptor 2 (CB2) (EC50=7.1), as shown in cAMP, GTPγS and β-arrestin recruitment assays. GP 1a is approximately 30-fold more selective for CB2 receptors than CB1 receptors and increases P-ERK1/2 expression in HL-60 cells in vitro. GP 1a is beneficial for skin wound healing. GP 1a inhibits inflammation and fibrogenesis while promoting epithelial re-formation.

MSU-42011 is an orally active retinoid X receptor-like (RXR) agonist. It potently inhibits the expression of iNOS, low SREBP-induced and activated RXR, and p-ERK at the protein level. MSU-42011 has demonstrated antitumor activity in a [kras]-driven mouse model of lung cancer and is effective for the treatment of preclinical [kras]-driven lung cancer with immunomodulatory activity.

SHP099 is an oral, highly selective, allosteric SHP2 (PTPN11) inhibitor with an IC₅₀ of 70 nM. SHP099 inhibits tumor cell proliferation and survival by stabilizing the autoinhibitory conformation of SHP2 and blocking RAS-ERK signaling. SHP099 inhibits the growth of cancer cells, such as MV4-11 and TF-1 cells (IC₅₀ = 0.32 and 1.73 μM). SHP099 can be used in tumor research.
