  Synthesis of a potent photoreactive acidic γ-secretase modulator for target identification in cells

  摘要：

  Supramolecular self-assembly of amyloidogenic peptides is closely associated with numerous pathological conditions. For instance, Alzheimers disease (AD) is characterized by abundant amyloid plaques originating from the proteolytic cleavage of the amyloid precursor protein (APP) by beta- and gamma-secretases. Compounds named gamma-secretase modulators (GSMs) can shift the substrate cleavage specificity of gamma-secretase toward the production of non-amyloidogenic, shorter A beta fragments. Herein, we describe the synthesis of highly potent acidic GSMs, equipped with a photoreactive diazirine moiety for photoaffinity labeling. The probes labeled the N-terminal fragment of presenilin (the catalytic subunit of gamma-secretase), supporting a mode of action involving binding to gamma-secretase. This fundamental step toward the elucidation of the molecular mechanism governing the GSM-induced shift in gamma-secretase proteolytic specificity should pave the way for the development of improved drugs against AD.
