A series of hydroxamate based HDAC inhibitors containing a phenylisoxazole as the CAP
group has been synthesized using nitrile oxide cycloaddition chemistry. An HDAC6 selective
inhibitor having a potency of∼ 2 picomolar was identified. Some of the compounds were
examined for their ability to block pancreatic cancer cell growth and found to be about 10-
fold more potent than SAHA. This research provides valuable, new molecular probes for use
in exploring HDAC biology.
