studied. The preparative results, the thermal stability of the photochemical substrate, and the limiting quantum yield values obtained from photoreactions with several nucleophiles suggest the possible usefulness of 2-fluoro-4-nitrophenyl ethers as biochemicalphotoprobes.
photosubstitutions of 2-fluoro-4-nitroanisole with several amines are studied from the preparative and the preliminary mechanistic points of view. The possible usefulness of this structure as biochemicalphotoprobe is discussed.

These 23 compounds were evaluated by competitive binding assay against aggregated Abeta42 fibrils using [(125)I]TZDM. All the isoindolone derivatives showed very good bindingaffinities with K(i) values in the subnanomolar range (0.42-0.94 nM). Among them, isoindol-1,3-diones 1i and 1k and isoindol-1-ones 2c and 2i exhibited excellent bindingaffinities (K(i)=0.42-0.44 and 0.46-0.49 nM) than those of
