  • Patent number: 6211149
    Abstract: Peptides are disclosed that inhibit the conversion of protease sensitive prion protein (PrPsen) to the protease resistant isoform (PrPres). These peptides comprise discrete fragments of prion proteins, and are shown to inhibit the in vitro conversion of PrPsen to PrPres in a cell-free system. Numerous peptides are disclosed that include at least two amino acid residues from the highly amyloidogenic region P113-120 of the PrP protein. None of these peptides conferred protease-resistance to the PrPsen molecules. The presence of residues 119 and 120 from the highly hydrophobic sequence AGAAAAGA (position 113 to 120) produced a particular inhibitory effect. The inhibition occurred with a high degree of specificity (e.g. with an IC50 of less than about 1000 &mgr;M).
