From the screening of a unique collection of 880 off-patent small organic molecules, we have found that quinacrine inhibits the interaction between a BH3 domain-derived peptide and the antiapoptotic protein Bcl-xL. Nuclear magnetic resonance spectroscopy confirmed that quinacrine binds to the hydrophobic groove that Bcl-xL uses for interacting with the BH3 domain of proapoptotic proteins. This activity can contribute to the anticancer activity of quinacrine.
通过对880种已过专利保护期的小分子有机物的独特集合进行筛选,我们发现奎纳克林可抑制一种源自BH3结构域的肽与抗凋亡蛋白Bcl-xL之间的相互作用。核磁共振波谱证实,奎纳克林可结合至Bcl-xL用于与促凋亡蛋白的BH3结构域相互作用的疏水凹槽。这一活性可能有助于奎纳克林的抗癌活性。
