MedKoo CAT#: 333182

CAS#: 155558-32-0

Description: Hydroxyfasudil, aslo known as HA1100, is a cell-permeable hydroxylated metabolite of HA-1077, is a potent inhibitor of Rho-associated kinase (ROCK) (Ki = 150 nM). Hydroxyfasudil alleviates demyelination through the inhibition of MOG antibody and microglia activation in cuprizone mouse model.
