Medchemexpress LLC Mk-28 | 864388-65-8 | 99.88% | 396.44 | 100 MG

MK-28 is a potent and selective PERK activator that demonstrates significant pharmacokinetic properties and high blood-brain barrier (BBB) penetration in mice. It has been shown to rescue cells from ER stress-induced apoptosis in vitro and improve systemic function and survival in R6/2 mice, an animal model for Huntington's disease. MK-28 also enhances motor and executive functions and delays the onset of death in R6/2 mice without causing toxicity.
