parthenolide in human breast cancer cells. We find that parthenolide, as well as other related exocyclic methylene lactone-containing sesquiterpenes, covalently modify cysteine 427 of focal adhesion kinase 1 (FAK1), leading to impairment of FAK1-dependent signaling pathways and breast cancer cell proliferation, survival, and motility. These studies reveal a functional target exploited by members of a
白菊内酯是小白菊植物的天然产物,是倍半萜内酯大家族的成员,具有多种生物和治疗活性,包括抗炎和抗癌作用。在这里,我们进一步研究基于基于活性蛋白谱的化学旋转平台的单性酚作用机理,以绘制由单性酚参与人乳腺癌细胞中的其他共价靶标的图谱。我们发现,单苯乙内酯,以及其他相关的含环亚甲基内酯的倍半萜烯,共价修饰粘着斑激酶1(FAK1)的半胱氨酸427,导致FAK1依赖的信号通路和乳腺癌细胞的增殖,存活和运动性受损。这些研究揭示了一大类抗癌天然产物成员利用的功能靶标。
