摘要

Histone deacetylases (HDACs) play an important role in the epige-netic regulation of gene expression by catalyzing the removal of acetyl groups from lysine residue of histone protein, stimulating chromatin condensation and promoting transcriptional repression.1,2 HDACs are divided into four classes on the basis of their homology to yeast HDACs: class I (HDAC1, 2, 3 and 8), class IIa (HDAC4, 5, 7 and 9), class IIb (HDAC6 and 10), class III (SIRT1, 2, 3, 4, 5, 6 and 7) and class IV (HDAC11). As aberrant epigenetic changes are a hallmark of cancer, HDACs are a promising target for an anticancer drug. The inhibitors of HDACs can induce cell-cycle arrest, promote differentiation and stimulate tumor cell death. In fact, several HDAC inhibitors are currently in clinical trials both for solid and hematological malignancies.1,2 Therefore, we attempted to search new HDAC inhibitors. As a result, we isolated a novel compound designated as JBIR-17 (1) from Streptomyces sp. 26634 (Figure 1). We report herein the isolation, structure elucidation and biological activity of 1.
