Abstract
In the course of our screening program for regulators of a molecular chaperone GRP78 expression, we isolated a novel inhibitor of GRP78 expression, designated as prunustatin A, from Streptomyces violaceoniger 4521-SVS3. The structure of prunustatin A was determined by a series of NMR analyses to be an oxidized type of the neoantimycin family. Prunustatin A inhibited the expression of GRP78 induced by 2-deoxyglucose in human fibrosarcoma HT1080 cells accompanied by global cell death without showing cytotoxicity under normal nutrient condition.Entities:
