A series of hydroxamic acid-based HDAC inhibitors with an indole amide residue at the terminus have been synthesized and evaluated. Compounds with a 2-indole amide moiety have been found as the most active inhibitors among the different regioisomers. Introduction of substituents on the indole ring further improved the potency and generated a series of very potent inhibitors with significant antiproliferative activity. A representative compound in the series, 7b, has been found to be orally active in tumor growth inhibition model. (C) 2003 Elsevier Science Ltd. All rights reserved.
