To find effective antiprioncompounds, we synthesized and evaluated various pyrazolonederivatives. Seven of 19 compounds showed inhibition of PrP-res accumulation and the remarkably active compound 13 showed an IC50 value of 3 nM in both ScN2a and F3 cell lines. Findings from studies on physicochemical and biochemical properties suggest that the action mechanism of these compounds does not correlate

A photographic element for color diffusion transfer photography is described wherein a polymeric vehicle layer is employed in a metallizable dye image-receiving layer, a layer adjacent thereto, or in both. The polymeric vehicle comprises a cross-linked polymer derived from recurring units of an acrylamide, a 1-vinyl-2-pyrrolidone or a 2-hydroxyethyl acrylate with a cross-linkable monomer.
