a variety of GJP14 derivatives were prepared using pyrrole derivatives, (haloalkyl)oxiranes, and amines, and their anti-prion activity was evaluated in TSE-infected cells. It was found that the tricyclic aromatic ring, a hydroxy group at the 2-position and an amino group at the 3-position of the N-propyl group were the basic requirements for anti-prion activity. The derivatives bearing an N-ortho-halobenzyl
