Pyrazole-based cathepsin S inhibitors with improved cellular potency
摘要:
High potency pyrazole-based noncovalent inhibitors of human cathepsin S (CatS) were developed by modification of the benzo-fused 5-membered ring heterocycles found in earlier series of Cats inhibitors. Although substitutions on this heterocyclic framework had a moderate impact on enzymatic potency, dramatic effects on cellular activity were observed. Optimization afforded indole- and benzothiophene-derived analogues that were high affinity Cats inhibitors (IC50 = 20-40 nM) with good cellular potency (IC50 = 30-340 nM). (c) 2007 Elsevier Ltd.
