Structural Elucidation of a Small Molecule Inhibitor of Protein Disulfide Isomerase
Compound libraries provide a starting point for multiple biological investigations, but the structural integrity of compounds is rarely assessed experimentally until a late stage in the research process. Here, we describe the discovery of a neuroprotective small molecule that was originally incorrectly annotated with a chemical structure. We elucidated the correct structure of the active compou...
متن کاملSmall molecule-induced oxidation of protein disulfide isomerase is neuroprotective.
Protein disulfide isomerase (PDI) is a chaperone protein in the endoplasmic reticulum that is up-regulated in mouse models of, and brains of patients with, neurodegenerative diseases involving protein misfolding. PDI's role in these diseases, however, is not fully understood. Here, we report the discovery of a reversible, neuroprotective lead optimized compound (LOC)14, that acts as a modulator...
متن کاملCatalysis of protein folding by protein disulfide isomerase and small-molecule mimics.
Protein disulfide isomerase (PDI) catalyzes the formation of native disulfide pairings in secretory proteins. The ability of PDI to act as a disulfide isomerase makes it an essential enzyme in eukaryotes. PDI also fulfills other important roles. Recent studies have emphasized the importance of PDI as an oxidant in the endoplasmic reticulum. Intriguing questions remain regarding how PDI is able ...
متن کاملDiscovery of an orally active small-molecule irreversible inhibitor of protein disulfide isomerase for ovarian cancer treatment.
Protein disulfide isomerase (PDI), an endoplasmic reticulum chaperone protein, catalyzes disulfide bond breakage, formation, and rearrangement. The effect of PDI inhibition on ovarian cancer progression is not yet clear, and there is a need for potent, selective, and safe small-molecule inhibitors of PDI. Here, we report a class of propynoic acid carbamoyl methyl amides (PACMAs) that are active...
