A Minimally-Masked Inactive Prodrug Of Panobinostat That Is Bioorthogonally Activated By Gold Chemistry
BIOORGANIC & MEDICINAL CHEMISTRY(2021)
摘要
The recent incorporation of Au chemistry in the bioorthogonal toolbox has opened up new opportunities to deliver biologically independent reactions in living environments. Herein we report that the O-propargylation of the hydroxamate group of the potent HDAC inhibitor panobinostat leads to a vast reduction of its anticancer properties (>500-fold). We also show that this novel prodrug is converted back into panobinostat in the presence of Au catalysts in vitro and in cell culture.
