To investigate the influence of the adamantyl group on the biological properties of known HDAC inhibitors with a 4-phenylcinnamic skeleton, a series of compounds having the adamantyl moiety in the cap structure were synthesized and compared to the corresponding hydroxamic acids lacking this group. An unexpected finding was the substantial reduction of inhibitory activity toward the tested enzymes, in particular HDAC6, following the introduction of the adamantyl group. In spite of the reduced ability to function as HDAC inhibitors, the compounds containing the adamantyl moiety still retained a good efficacy as antiproliferative and proapoptotic agents. A selected compound (2c; ST3056) of this series exhibited an appreciable antitumor activity against the colon carcinoma xenograft HCT116. (c) 2014 Elsevier Masson SAS. All rights reserved.
