Design, synthesis, and evaluation of resveratrol derivatives as Aß1–42 aggregation inhibitors, antioxidants, and neuroprotective agents
摘要:
A series of novel resveratrol derivatives were designed, synthesised and evaluated as potential therapeutic agents for the treatment of Alzheimer's disease. Among these compounds, compound 7l, (E)-5-(4-(isopropylamino)styryl)benzene-1,3-diol, exhibited potent beta-amyloid aggregation inhibition activity, which was confirmed by a ThT fluorescence assay (71.65% at 20 mu M) and transmission electron microscopy (TEM). Compound 7l also exhibited good antioxidant activity (4.12 Trolox equivalents in an oxygen radical absorbance capacity assay and a 37% reduction in reactive oxygen species in cells at 10 mu M). The cytotoxicity analysis of compounds 7f, 7i, 7j and 7l indicated that these compounds have lower toxicities than resveratrol at 60 mu M. (C) 2012 Elsevier Ltd. All rights reserved.

(3) a plurality of precondensed, inorganic nanoparticles; (b) exposing, using a multibeam interference technique involving at least three beams, at least a portion of the photoreactive composition to radiation of appropriate wavelength, spatial distribution, and intensity to produce a two-dimensional or three-dimensional periodic pattern of reacted and non-reacted portions of the photoreactive composition; (c) exposing at least a portion of the non-reacted portion of the photoreactive composition to radiation of appropriate wavelength and intensity to cause multi-photon absorption and photoreaction to form additional reacted portion; (d) removing the non-reacted portion or the reacted portion of the photoreactive composition to form interstitial void space; and (e) at least partially filling the interstitial void space with at least one material having a refractive index that is different from the refractive index of the remaining portion.
