3,3'-Spirocyclopentene oxindoles structurally related to Wang's spiropyrrolidine oxindoles have been highlighted as a new class of antiproliferative agents against cancer cell lines with wild-type p53 status (IC up to 0.96 μM on SJSA-1 and 2.9 μM in HCT116 p53-wt). Inhibition of the MDM2-p53 interactions has been demonstrated through in vitro HTRF assays (IC up to 3.1 nM), while Western blot analysis showed activation of p53 selectively in HCT116 cancer cell lines with wild-type p53.
3,3'-螺环戊烯氧吲哚类化合物与 Wang 的螺吡咯烷吲哚类化合物结构相关,已被确定为具有野生型 p53 状态的癌细胞系的新型抗增殖剂(对 SJSA-1 的 IC 高达 0.96 μM,对 HCT116 p53-wt 的 IC 高达 2.9 μM)。通过体外 HTRF 测定(最高达 3.1 nM)证实了对 MDM2-p53 相互作用的抑制,而 Western blot 分析显示,在具有野生型 p53 的 HCT116 癌细胞系中,p53 被选择性激活。
