                                        Comment: Icerguastat (IFB-088, Sephin1) selectively inhibits the regulatory subunit PPP1R15A within the PPP1R15A/PP1c phosphatase complex [2]. Inhibiting PPP1R15A results in reduced dephosphorylation of the translation initiation factor eIF2α, which rescues cells from proteostasis collapse. Structurally icerguastat is a guanabenz derivative but it has no α2-adrenerceptor agonist activity. Icerguastat is designed to maintain an active integrated stress response as a cytoprotective mechanism to combat the toxic effects of cellular stress [1].
