Two series of SAHA-liked hydroxamate analogues were designed, synthesized and evaluated for their biological activities against nuclear HDACs. Compounds of Series I were found to be very effective inhibitors of cancer cell growth in the PC-3, Hut78, K562 and Jurkat E6-1 cancer cell lines with mean $IC_50}$ values from $0.54\mu}M$ (Ic, Jurkat E6-1) to $7.73\mu}M$ (Ib, K562), indicating that they are cell permeable and the benzimidazolyl-based ligands are flexible enough to occupy the binding site of HDAC.
两系列类似于SAHA的羟肟酸类似物被设计、合成并评估了它们对核HDACs的生物活性。第一系列化合物被发现对PC-3、Hut78、K562和Jurkat E6-1肿瘤细胞系具有非常有效的抑制生长作用,其平均$IC_50}$值从$0.54\mu}M$(Ic,Jurkat E6-1)至$7.73\mu}M$(Ib,K562),表明这些化合物具有细胞通透性,且苯并咪唑基的配体足够柔韧以占据HDAC的结合位点。
