The first synthesis of the non-peptidic snail toxin 6-bromo-2-mercaptotryptamine dimer (BrMT)2 is described, along with the preparation of its lower and higher thio homologs. The synthetic (BrMT)2 and its derivatives reported herein are all capable of slowing the activation of the Kv1.1 potassium ion channel. Only the monosulfide variant shows significant slowing of the deactivation process. This synthetic
描述了非肽蜗牛毒素6-溴-2-巯基色胺二聚体(BrMT)2的首次合成,以及其低级和高级硫代同系物的制备。本文报道的合成(BrMT)2及其衍生物都能够减慢K v 1.1钾离子通道的活化。仅单硫化物变体显示出减活过程的显着减慢。现在可以将这种合成策略应用于创建一组更广泛的化合物,这些化合物在连接两个单体,吲哚环核上的取代基和末端胺的连接基的长度上各不相同。
