  NSAID-derived γ-secretase modulation requires an acidic moiety on the carbazole scaffold

  摘要：

  Modulation of gamma-secretase activity holds potential for the treatment of Alzheimer's disease. Most NSAID-derived gamma-secretase modulators feature a carboxylic acid, which may impair blood-brain barrier permeation. The structure activity relationship of 33 carbazoles featuring diverse carboxylic acid isosteres or metabolic precursors thereof was established in a cellular amyloid secretion assay. The modulatory activity was observed for acidic moieties and metabolically labile esters only, which supports our hypothesis of an acid-lysine interaction to be relevant for this type of gamma-secretase modulators.

  Scaffold of the Cyclooxygenase-2 (COX-2) Inhibitor Carprofen Provides Alzheimer γ-Secretase Modulators

  摘要：

  N-Sulfonylated and N-alkylated carprofen derivatives were investigated for their inhibition and modulation of gamma-secretase, which is associated with Alzheimer's disease. The introduction of a lipophilic substituent transformed the COX-2 inhibitor carprofen into a potent gamma-secretase modulator. Several compounds (e.g., 9p, 11f) caused selective reduction of A beta(42) and an increase of A beta(38). The most active compounds displayed activities in the low micromolar range and no effect on the gamma-secretase cleavage at the epsilon-site.
