Abstract
Hydroxamate-based HDAC inhibitors have promising anticancer
activities
but metabolic instability and poor pharmacokinetics leading to poor
in vivo results. QSAR and PK studies of HDAC inhibitors showed that
a γ-lactam core and a modified cap group, including halo, alkyl,
and alkoxy groups with various carbon chain linkers, improved HDAC
inhibition and metabolic stability. The biological properties of the
γ-lactam HDAC inhibitors were evaluated; the compound designated <b>8f</b> had potent anticancer activity and high oral bioavailability
