Description
Raphin1 acetate is an orally bioavailable, selective inhibitor of the regulatory phosphatase PPP1R15B (R15B). Raphin1 acetate binds strongly to the R15B-PP1c holophosphatase (Kd=33 nM), and shows ~30-fold selective in binding R15B-PP1c over R15A-PP1c. Raphin1 acetate crosses the blood-brain barrier, and reduces organismal and molecular deficits in a mouse model of a protein misfolding disease.

How to use
In Vitro:
Raphin1 acetate causes a rapid and transient accumulation of its phosphorylated substrate, resulting in a transient attenuation of protein synthesis. Raphin1 acetate inhibits the recombinant R15B-PP1c holoenzyme, but not the closely related R15A-PP1c, by interfering with substrate recruitment.
In Vivo:
Raphin1 acetate improves weight of HD82Q mice treated from 4 to ∼10 weeks of age with 2 mg/kg of Raphin1 once a day by oral gavage. Raphin1 acetate also decreases SDS-insoluble huntingtin assemblies and nuclear inclusions in the cortex of HD82Q mice.
