研究表明苦参碱对多种癌症具有抗肿瘤活性。然而，其抗癌作用在癌细胞中的直接靶点尚未确定。本研究的目的是寻找苦参碱抑制癌细胞增殖的分子靶点，并探讨其作用机制。实验结果表明，苦参碱在体外和体内均能抑制肿瘤的增殖。用苦参碱-氨基偶联树脂和液相色谱-质谱/质谱（LC-MS/MS）进行下拉分析，确定Src为苦参碱的靶点。细胞热移实验（CETSA）和药物亲和力反应靶稳定性（DARTS）证实苦参碱与Src直接结合。生物信息学预测和pull-down实验表明Src激酶结构域是其与苦参碱相互作用所必需的，而激酶结构域中的Ala392参与了苦参碱与Src的相互作用。有趣的是，苦参碱被证明通过阻断Src激酶结构域Tyr419的自磷酸化，以非atp竞争的方式抑制Src激酶活性。苦参碱通过靶向Src下调MAPK/ERK、JAK2/STAT3和PI3K/Akt信号通路的磷酸化水平。总之，苦参碱靶向Src，抑制其激酶活性，下调其下游MAPK/ERK、JAK2/STAT3和PI3K/Akt磷酸化信号通路，抑制癌细胞的增殖。
Studies have shown that matrine has antitumor activity against many types of cancers. However, the direct target in cancer cells of its anticancer effect has not been identified. The purpose of this study was to find the molecular target of matrine to inhibit the proliferation of cancer cells and explore its mechanism of action. Herein we showed that matrine inhibited the proliferation of cancer in vitro and in vivo. Pull-down assay with matrine-amino coupling resins and liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) identified Src as the target of matrine. Cellular thermal shift assay (CETSA) and drug affinity responsive target stability (DARTS) provided solid evidences that matrine directly bound to Src. Bioinformatics prediction and pull-down experiment demonstrated that Src kinase domain was required for its interaction with matrine and Ala392 in the kinase domain participated in matrine–Src interaction. Intriguingly, matrine was proven to inhibit Src kinase activity in a non-ATP-competitive manner by blocking the autophosphorylation of Tyr419 in Src kinase domain. Matrine down-regulated the phosphorylation levels of MAPK/ERK, JAK2/STAT3, and PI3K/Akt signaling pathways via targeting Src. Collectively, matrine targeted Src, inhibited its kinase activity, and down-regulated its downstream MAPK/ERK, JAK2/STAT3, and PI3K/Akt phosphorylation signaling pathways to inhibit the proliferation of cancer cells.
