A novel series of compounds containing a uracil moiety as the connection unit between a phenyl/phenylalkyl portion and a N-hydroxy-polymethylenealkanamide or -methylenecinnamylamide group (uracil-based hydroxamic acids, UBHAs) was tested against maize histone deacetylases (HDACs) and mouse HDAC1. Compounds with a phenyl/benzyl ring at the uracil-C6 position and bearing 4-5 carbon units as well as a
测试了一系列新的化合物,其中包含尿嘧啶部分作为苯基/苯基烷基部分与N-羟基-聚亚甲基铝酰胺或-亚甲基肉桂酰胺基之间的连接单元(基于尿嘧啶的异羟肟酸,UBHA)对玉米组蛋白脱乙酰基酶(HDACs)和小鼠的抑制作用HDAC1。最有效的抑制剂是在尿嘧啶-C6位置具有苯基/苄基环且带有4-5个碳单元以及间-或对-亚甲基肉桂基部分作为间隔基的化合物。在基于细胞的人类HDAC1和HDAC4分析中,测试的两个UBHA抑制了HDAC1,但没有抑制HDAC4的免疫沉淀活性。在人白血病U937细胞中进行测试时,一些UBHA会导致细胞周期的G1期停滞。此外,1j显示出高抗增殖和剂量依赖性的粒细胞分化特性。
