Romidepsin，也稱為FK228或縮肽，是組蛋白脫乙酰酶(HDACs)的有效和選擇性抑制劑，HDACs與沉默的腫瘤抑制基因的再表達(dá)的調(diào)節(jié)有關(guān)。它是第一個(gè)表現(xiàn)出抗腫瘤活性的HDAC抑制劑，最初從日本土壤樣本中發(fā)現(xiàn)的桿狀革蘭氏陰性細(xì)菌紫色色桿菌中分離。Romidepsin對(duì)HDAC1和HDAC2酶(I類)表現(xiàn)出更強(qiáng)的抑制作用，與HDAC4和HDAC6酶(II類)相比，從N-末端組蛋白尾部的賴氨酸殘基中去除乙?；⒈３指_放和轉(zhuǎn)錄活性的染色質(zhì)狀態(tài)。除了HDAC抑制作用，romidepsin還能夠在成人惡性腫瘤中誘導(dǎo)細(xì)胞周期停滯、細(xì)胞分化、凋亡和基因表達(dá)的改變。
