δ-Lactam-based hydroxamic acids, inhibitors of histone deacetylase (HDAC), have been synthesized via ring closure metathesis of key diene intermediates followed by conversion to hydroxamic acid analogues. The hydroxamic acids 12a, 12b, and 17c showed potent inhibitory activity in HDAC enzyme assay. The hydroxamic acid 12b exhibited growth inhibitory activity on five human tumor cell lines, showing good sensitivity on the MDA-MB-231 breast tumor cell.
