with spiro ring containing sulfur atoms as cap group and linear carbochain as linker was designed and synthesized as HDACs inhibitors. Several compounds possessed more potent HDAC8 inhibitory activity than clinically used drug SAHA, although their HDAC1 inhibitory activities and anti-proliferative activities against human breast cancer cell lines (MCF-7, MDA-MB-231) and prostate cancer cell line (PC-3)
设计并合成了一系列新的三肽模拟物,其螺环含硫原子作为帽基,线性碳链作为连接基,可作为HDACs抑制剂。尽管几种化合物对人乳腺癌细胞系(MCF-7,MDA-MB-231)和前列腺癌细胞系(PC-3)具有HDAC1抑制活性和抗增殖活性,但它们具有比临床药物SAHA更有效的HDAC8抑制活性。 )并不令人满意。其中,化合物11l和11k对HDAC8表现出优异的效力(IC 50分别为0.021±0.004μM和0.035±0.007μM,而SAHA为0.70±0.12μM),并且相对于HDAC1具有良好的选择性。迄今为止,几乎没有报道具有线性连接体的异羟肟酸衍生物比HDAC1具有HDAC8选择性。
