Aryl sulfones: a new class of gamma-secretase inhibitors.

Bioorg. Med. Chem. Lett. 15(10) , 2685-8, (2005)

The development of a novel series of 4-aryl, 4-phenylsulfonyl cyclohexananone-derived gamma-secretase inhibitors for the potential treatment of Alzheimer's disease is described.

Synthesis and evaluation of [(1R)-1-amino-2-(2,5-difluorophenyl)ethyl]cyclohexanes and 4-[(1R)-1-amino-2-(2,5-difluorophenyl)ethyl]piperidines as DPP-4 inhibitors.

Bioorg. Med. Chem. Lett. 21 , 1880-1886, (2011)

A series of 4-amino cyclohexanes and 4-substituted piperidines were prepared and evaluated for inhibition of DPP-4. Analog 20q displayed both good DPP-4 potency and selectivity against other proteases...
