片藻素是一类从海洋无脊椎动物中分离出来的六环吡咯生物碱,具有良好的抗肿瘤活性。它们通过多靶点机制诱导凋亡细胞死亡,包括拓扑异构酶I的抑制、与DNA的相互作用以及对线粒体的直接作用。我们在这里报道,片层蛋白抑制几种与癌症相关的蛋白激酶,如周期蛋白依赖性激酶、双特异性酪氨酸磷酸化活化激酶1A、酪蛋白激酶1、糖原合成酶激酶3和PIM-1。研究发现,片层蛋白对蛋白激酶的影响与其对细胞死亡的作用之间存在良好的相关性,表明对特定激酶的抑制可能与片层蛋白的细胞毒性有关。结构/活性关系为优化片层蛋白作为激酶抑制剂提供了几种途径。
Lamellarins, a family of hexacyclic pyrrole alkaloids originally isolated from marine invertebrates, display promising anti-tumor activity. They induce apoptotic cell death through multi-target mechanisms, including inhibition of topoisomerase I, interaction with DNA and direct effects on mitochondria. We here report that lamellarins inhibit several protein kinases relevant to cancer such as cyclin-dependent kinases, dual-specificity tyrosine phosphorylation activated kinase 1A, casein kinase 1, glycogen synthase kinase-3 and PIM-1. A good correlation is observed between the effects of lamellarins on protein kinases and their action on cell death, suggesting that inhibition of specific kinases may contribute to the cytotoxicity of lamellarins. Structure/activity relationship suggests several paths for the optimization of lamellarins as kinase inhibitors.
