CIP2A is an oncoprotein that upregulates p-Akt and promotes cancer cell proliferation and survival. The proteasome inhibitor bortezomib has been shown to reduce CIP2A and lead to cell apoptosis. Here; we modified the functional group of bortezomib to generate a series of novel compounds and conducted a structure–activity relationship (SAR) study. The results showed that compound 1 was able to repress CIP2A expression and cell apoptosis in the same manner as bortezomib, but with less potency in inhibition of proteasome activity. This finding provides a new direction for the design of CIP2A inhibitors.
CIP2A 是一种上调 p-Akt 并促进癌细胞增殖和存活的肿瘤蛋白。蛋白酶体抑制剂硼替佐米已被证明能减少 CIP2A 并导致细胞凋亡。在此,我们对硼替佐米的官能团进行了修饰,生成了一系列新型化合物,并进行了结构-活性关系(SAR)研究。结果表明,化合物 1 能够以与硼替佐米相同的方式抑制 CIP2A 的表达和细胞凋亡,但对蛋白酶体活性的抑制作用较弱。这一发现为 CIP2A 抑制剂的设计提供了新的方向。
