To find novel non-hydroxamate histone deacetylase (HDAC) inhibitors, a series of compounds modeled after suberoylanilide hydroxamic acid (SAHA) was designed and synthesized. In this series, compound 7, in which the hydroxamic acid of SAHA is replaced by a thiol, was found to be as potent as SAHA, and optimization of this series led to the identification of HDAC inhibitors more potent than SAHA. In cancer
为了找到新型的非异羟肟酸酯组蛋白脱乙酰基酶(HDAC)抑制剂,设计并合成了以亚磺酰苯胺异羟肟酸(SAHA)为模型的一系列化合物。在该系列中,发现化合物7(其中SAHA的异羟肟酸被硫醇替代)与SAHA一样有效,该系列的优化导致鉴定出比SAHA更有效的HDAC抑制剂。在癌细胞生长抑制测定中,S-异丁酰基衍生物51显示出强活性,并且其效力与SAHA相当。通过Western印迹分析证实癌细胞生长抑制活性是组蛋白过度乙酰化和随后诱导p21(WAF1 / CIP1)的结果。
