The histone deacetylase (HDAC) enzyme plays an important role in gene transcription. Inhibitors of histone deacetylases induce cell differentiation and suppress cell proliferation in tumor cells. Hydroxamates with rigid linker have displayed better inhibition profiles than those with linear and flexible aliphatic linkers. We have designed and synthesized several potential histone deacetylase inhibitors
组蛋白去乙酰化酶 (HDAC) 在基因转录中起重要作用。组蛋白去乙酰化酶抑制剂在肿瘤细胞中诱导细胞分化并抑制细胞增殖。具有刚性接头的异羟肟酸盐比具有线性和柔性脂肪族接头的异羟肟酸盐显示出更好的抑制特性。我们设计并合成了几种潜在的组蛋白去乙酰化酶抑制剂,在接头区域具有哌嗪部分,以测试接头灵活性降低的影响。评估了抑制剂对人 HDAC3/NCoR2 和 HDAC8 的抑制作用。发现 N-羟基甲酰胺衍生物(化合物 4a-d)比 N-羟基乙酰胺衍生物(化合物 6a-d)对 HDAC8 的效果更好。在合成的化合物中,4a (HDAC8, IC50: 3rd
