noricumazole A, and their glycosylated derivatives are new, structurally related secondary metabolites isolated from Sorangium cellulosum. Their structures have been fully assigned by a joint strategy that relied on spectroscopy, derivatization, fragmentation, and finally the first total synthesis of noricumazole A.
共同的努力:抗真菌药icumazole A,钾离子通道抑制剂诺替唑[noricumazole A]及其糖基化衍生物是新的,与结构相关的二级代谢产物,其是从橙皮纤维素中分离得到的。它们的结构已通过联合策略完全确定,该策略依赖于光谱学,衍生化,碎片化,最后是首次合成诺霉唑A。
