Ladder-shaped polyether (LSP) compounds, such as brevetoxins and ciguatoxins, are thought to interact with transmembrane (TM) proteins. As a model LSP compound, we designed and synthesized an artificial tetracyclic ether (1) and evaluated its interaction with glycophorin A (GpA), a membrane protein known to dimerize or oligomerize between membrane-integral alpha-helical domains. Model compound 1 was
梯形聚醚(LSP)化合物(如短毒素和雪茄毒素)被认为与跨膜(TM)蛋白相互作用。作为模型LSP化合物,我们设计并合成了人工四环醚(1),并评估了其与糖蛋白A(GpA)的相互作用,该蛋白已知是在膜整合性α螺旋结构域之间二聚或寡聚的膜蛋白。当通过SDS-PAGE检查时,发现模型化合物1以与天然LSP类似的方式诱导寡聚GpA的解离。结果表明,即使是人工四环醚也具有与TM蛋白相互作用的能力,大概是通过具有GXXXG基序的分子间氢键(Cα-Hcdots,三个点,居中的O)。
