Uses
PERK-IN-5 is a highly potent, selectively and orally bioavailable PERK inhibitor (IC50s of 2 and 9 nM for PERK and p-eIF2α, respectively). PERK-IN-5 can significantly inhibit tumor growth in the 786-O renal cell carcinoma xenograft tumor model[1].

PERK-IN-5 (compound 28) (10-48 μM) is relatively stable in both human and dog hepatocytes and is characterized with long half-lives[1].
PERK-IN-5 (3-100 mg/kg; p.o.; 0.25-24 hours) has robust pharmacokinetics in CD1 mice, with Cmax of 3353 ng/mL, AUC0-last of 5153 h*ng/mL, and bioavailability of 70%[1].PERK-IN-5 (3 or 10 mg/kg; p.o.; twice daily, for 28 days) has statistically significant tumor growth inhibition[1].
