General description
A cell-permeable, blood-brain barrier permeable, non-toxic pyrazolone compound that potently blocks mutant Cu/Zn SOD1 cytotoxicity (EC50 = 67 nM in PC12 cells expressing mutant G93A SOD1). Shown to directly interact with 26S proteasome PSMC1 and PSMC4 and the chaperone protein TCP-1 and enhance proteasome activity. Offers neuroprotection against protein aggregation induced toxicity and prolongs the survival of ALS transgenic mice by 13.3% (20 mg/kg, i.p., q.d.) Demonstrates attractive microsomal (T1/2 = 93 & 36 min in human & mouse, respectively) and metabolic stability, aqueous solubility (250 µM) and PK profile in mice. Poorly affects the activities of 68-enzymes & receptors, hERG and Cyp450 isozymes at 10 µM.
