  Synthesis and Structure−Affinity Relationships of Novel Dibenzylideneacetone Derivatives as Probes for β-Amyloid Plaques

  摘要：

  A new and extensive set of dibenzylideneacetone derivatives was synthesized and screened for affinity toward A beta(1-42) aggregates. Structure-activity relationships revealed the binding of dibenzylideneacetones to be affected by various substituents. The introduction of a substituent group in the ortho position reduced or abolished the binding. However, the para position was highly tolerant of sterically demanding substitutions. Three radioiodinated ligands (6, 70, and 71) and two F-18 fluoro-pegylated (FPEG) ligands (83 and 85) were prepared, all of which displayed high affinity folr A beta(1-42) aggregates (K-i ranging from 0.9 to 7.0 nM). In biodistribution experiments, they exhibited good initial penetration (1.59, 4.68, 4.56, 4.13, and 5.15% ID/g, respectively, at 2 min) of and fast clearance from the brain. Autoradiography with sections of postmortem AD brain and transgenic mouse brain confirmed the high affinity of these tracers. These preliminary results strongly suggest the dibenzylideneacetone structure to be a potential new scaffold for beta-amyloid imaging probes.

  A novel Hemozoin Detoxification Protein (HDP) from Plasmodium and related parasites is provided as a target for therapeutic intervention in diseases caused by the parasites. HDP has been shown to play a critical role in adhesion to, or invasion into, host cells by the parasite. Furthermore, HDP catalyzes the neutralization of heme by the parasite, by promoting its polymerization into hemozoin. This invention provides methods and compositions for therapies based on the administration of protein, DNA or cell-based vaccines and/or antibodies based on HDP, or antigenic epitopes of HDP, either alone or in combination with other parasite antigens. Methods for the development and use of compounds that inhibit the catalytic activity of HDP, and diagnostic and laboratory methods utilizing HDP are also provided. HDP is also referred to herein as Fasciclin Related Adhesive Protein (FRAP).
