The proteolytic enzyme β-secretase (BACE1) plays a central role in the synthesis of the pathogenic β-amyloid in Alzheimer's disease. SAR studies of the S2′ region of the BACE1 ligand binding pocket with pyrazolyl and thienyl P2′ side chains are reported. These analogs exhibit low nanomolar potency for BACE1, and demonstrate >50- to 100-fold selectivity for the structurally related aspartyl proteases BACE2 and cathepsin D. Small groups attached at the nitrogen of the P2′ pyrazolyl moiety, together with the P3 pyrimidine nucleus projecting into the S3 region of the binding pocket, are critical components to ligand's potency and selectivity. P2′ thiophene side chain analogs are highly potent BACE1 inhibitors with excellent selectivity against cathepsin D, but only modest selectivity against BACE2. The cell-based activity of these new analogs tracked well with their increased molecular binding with EC50 values of 0.07-0.2 μM in the ELISA assay for the most potent analogs.

Page/Page column 82-83, (2008/06/13)
The present invention relates generally to bis-amide group containing pharmaceutical agents, and in particular, to multicyclic bis-amide MMP-13 inhibitor compounds. More particularly, the present invention provides a new class of MMP-13 inhibiting compounds, containing a pyrimidinyl bis-amide group in combination with a heterocyclic moiety, that exhibit an increased potency and solubility in relation to currently known bis-amide group containing MMP-13 inhibitors.
