Curacin A is a structurally novel antimitotic agent isolated from the Caribbean cyanobacterium Lyngbya majuscula. Its planar structure has been previously determined from a spectroscopic investigation. Here, we define the complete relative and absolute configuration of curacin A by comparison of products obtained from chemical degradation of the natural product with the same substances prepared by
Curacin A是一种结构新颖的抗有丝分裂剂,从加勒比海蓝藻Lyngbya majuscula中分离出来。先前已经通过光谱学研究确定了其平面结构。在这里,我们通过比较天然产物的化学降解产物与合成制备的相同物质,定义了curacin A的完整相对构型和绝对构型。示出了姜黄素A具有2 R,13 R,19 R,21 S的绝对构型。
