The total synthesis of melleumin A (1), a novel cyclic depsipeptide isolated from the myxomycete Physarum melleum, and 3-epi-melleumin A (6) was achieved. Melleumin A-like compounds were also designed and synthesized; analysis of these melleumin A-like compounds showed moderate Wnt signal inhibition. Comparison of the inhibition activity of melleumin B and its three epimers, melleumin A, 3-epi-melleumin
melleumin A的总合成(1)中,从分离粘菌一个新的环状缩肽绒泡melleum,和3-外延-melleumin A(6)中的溶液来实现。还设计并合成了类似Mleuleumin A的化合物。这些类melleumin A样化合物的分析显示中等温特信号抑制。褪黑素抑制活性的比较乙及其三种差向异构体,melleumin A,3- epi- melleumin A和三种melleumin A-like化合物导致了对活性分子结构构象的进一步研究。melleumin的支架是寻找“肽样”的潜在目标温特 信号抑制剂。
