of acyclic, truncated microcystin analogues, comprised of the dienic beta-amino acid (Adda) and up to four additional amino acids characteristic of the parent toxin, was synthesized and screened for activity as inhibitors of PP1 and PP2A. Despite a recent report to the contrary for a microcystin-derived tetrapeptide degradation product, none approaches the potency of microcystin itself.
合成了一系列无环的,截短的微囊藻毒素类似物,包括二齿β-氨基酸(Adda)和多达四个母体毒素特征的其他氨基酸,并筛选了作为PP1和PP2A抑制剂的活性。尽管最近有报道相反地报道了微囊藻毒素衍生的四肽降解产物,但是没有一种方法能达到微囊藻毒素本身的效力。
