Primary TargetPDI

Cell permeable: yes

General description

A cell-permeable, blood brain barrier permeable, orally bioavailable, non-toxic benzothiazolone derived compound that acts a potent, reversible and non-covalent inhibitor of protein disulfide isomerase (PDI) reductase activity (K_d = 61.7 nM for PDIa). Shown to bind to PDIa stoichiometrically (1:1), adjacent to the active site, and enforce PDI to adopt an oxidized conformation. Dose-dependently rescues both PC12 cells (EC₅₀ = 500 nM) and medium spiny neurons from mutant huntingtin neurotoxicity. Exhibits favorable microsomal (k = 0.0016, t_1/2 = 438.7 min, CL_int = 0.17 ml/min/g mouse liver) and blood plasma stability (k = 0.0049, t_1/2 = 144 min and 49.9% remains after 2 h incubation) and is well tolerated in mice (20 mg/kg, p.o.).
