Discovery, Structure–Activity Relationship, and Biological Evaluation of Noninhibitory Small Molecule Chaperones of Glucocerebrosidase
摘要:
A major challenge in the field of Gaucher disease has been the development of new therapeutic strategies including molecular chaperones. All previously described chaperones of glucocerebrosidase are enzyme inhibitors, which complicates their clinical development because their chaperone activity must be balanced against the functional inhibition of the enzyme. Using a novel high throughput screening methodology, we identified a chemical series that does not inhibit the enzyme but can still facilitate its translocation to the lysosome as measured by immunostaining of glucocerebrosidase in patient fibroblasts. These compounds provide the basis for the development of a novel approach toward small molecule treatment for patients with Gaucher disease.
Synthesis and structure–activity relationship of tetrahydropyrazolopyrimidine derivatives—A novel structural class of potent calcium-sensing receptor antagonists
derivatives containing an adamantylgroup were synthesized and evaluated as potential calcium-sensing receptor (CaSR) antagonists. After chemical modification of 9a, which was identified as a hit compound in a random screening of CaSR antagonist assay, 7,7-dimethyl derivative 16c was found to be the most active compound of this new series (IC50 = 10 nM). We report the synthesis of this series and their
