Discovery of 2-aminothiazoles as potent antiprion compounds.

ABSTRACT: Prion diseases are fatal, untreatable neurodegenerative diseases caused by the accumulation of the misfolded, infectious isoform of the prion protein (PrP), termed PrP(Sc). In an effort to identify novel inhibitors of prion formation, we utilized a high-throughput enzyme-linked immunosorbent assay (ELISA) to evaluate PrP(Sc) reduction in prion-infected neuroblastoma cell lines (ScN2a). We screened a library of approximately 10,000 diverse small molecules in 96-well format and identified 121 compounds that reduced PrP(Sc) levels at a concentration of 5 microM. Four chemical scaffolds were identified as potential candidates for chemical optimization based on the presence of preliminary structure-activity relationships (SAR) derived from the primary screening data. A follow-up analysis of a g
