effective treatment for this metastatic disease. In the last years, histone deacetylase inhibitors (HDACIs) have been studied as a possible therapeutic treatment for UM, alone or in association with other chemotherapeutic agents. Here we synthesised a series of new HDACIs based on the SAHA scaffold bearing an (arylidene)aminoxy moiety. Their HDAC inhibitory activity was evaluated on isolated human HDAC1
摘要 葡萄膜黑色素瘤(UM)代表一种侵略性癌症,目前,尚无针对这种转移性疾病的有效治疗方法。在过去的几年中,已经研究了组蛋白脱乙酰基酶抑制剂(HDACIs)作为UM的一种可能的治疗方法,可以单独使用或与其他化学治疗剂联合使用。在这里,我们基于带有(亚芳基)氨氧基部分的SAHA支架合成了一系列新的HDACI。通过荧光测定法对分离的人类HDAC1、3、6和8评估了它们的HDAC抑制活性,并通过分子对接研究了它们在HDAC催化位点的结合模式。最有希望的产品是喹啉衍生物VS13,一种HDAC6的纳摩尔抑制剂,在微摩尔浓度下对UM细胞系表现出良好的抗增殖作用,并且具有与SAHA类似的修饰HDAC靶基因mRNA水平的能力。
