A novel set of dual gamma-secretase/PPAR gamma modulators characterized by a 2-benzyl hexanoic acid scaffold is presented. Synthetic efforts were focused on the variation of the substitution pattern of the central benzene. Finally, we obtained a new class of 2,5-disubstituted 2-benzylidene hexanoic acid derivatives, which act as dual gamma-secretase/PPAR gamma modulators in the low micromolar range. We have explored broad SAR and successfully improved the dual pharmacological activity and the selectivity profile against potential off-targets such as NOTCH and COX. Compound 17 showed an IC50 A beta 42 = 2.4 mu M and an EC50 PPAR gamma = 7.2 mu M and could be a valuable tool to further evaluate the concept of dual gamma-secretase/PPAR gamma modulators in animal models of Alzheimer's disease.
