New dipolar and non-dipolar poly(phenylenevinylene) dendrimers bearing electron-donating and electron-withdrawing groups have been efficiently synthesized using Heck and Horner-Wadsworth-Emmons reactions. The photoluminescence of these systems may be tuned in the blue zone by choosing the appropriate peripheral groups. Despite the meta-substitution pattern, large Stokes shifts can be observed when

New bis-styrylpyridine and bis-styrylbenzene derivatives were designed and synthesized. These 34 compounds were evaluated by A beta fibril formation inhibitory assay using thioflavin T as a dye (named ThT assay). Most of them showed excellent inhibitory activities for A beta fibril formation at IC50 of 0.1-2.7 mu M which is comparable to curcumin (IC50 of 0.8 mu M). Among them, nine compounds were screened for their cytotoxicities on HT-22 cell by MTT assay at 1, 10, and 50 mu M. In particular, 1-7 and II-2 exhibited the best combination of inhibitory activity and compound cytotoxicity. (c) 2006 Elsevier Ltd. All rights reserved.
