Icerguastat Carbonate
Based on 4 publication(s) in Google Scholar
Icerguastat (Sephin1) Carbonate, a derivative of Guanabenz lacking the α2-adrenergic activity, is a selective inhibitor of the phosphatase regulatory subunit PPP1R15A (R15A). Icerguastat Carbonate inhibits eIF2α dephosphorylation, thereby prolonging the protective response. Anti-prion effect.
