Progress in clinical trial of histone deacetylase （HDAC） inhibitors for non-small cell lung cancers

Histone deacetylase (HDAC) inhibitors, which represent a structurally diverse group of molecules, have emerged as a novel therapeutic class of molecules with significant anticancer potential. Vorinostat and romidepsin, known as the first generation of HDAC inhibitors, were approved in the United States for the treatment of T-cell lymphomas. Preliminary activity of HDAC inhibitors has also been observed in non-small cell lung cancer (NSCLC) in combination with the existing treatment regimens, of which is the focus of the current review.
