New sesquiterpene quinones, metachromins X (1) and Y (2), together with the known metachromins C (3), J (4), and T (5), were isolated as inhibitors of cell cycle progression in the HeLa/Fucci2 cells. The structure of 1 was assigned by spectroscopic data and confirmed by a total synthesis. The planar structure of 2 was determined by interpretation of spectroscopic data, whereas its absolute configuration
分离出新的倍半萜醌,变色素X(1)和Y(2)以及已知的变色素C(3),J(4)和T(5)作为HeLa / Fucci2细胞中细胞周期进程的抑制剂。1的结构由光谱数据确定,并通过总合成得到证实。2的平面结构是通过光谱数据的解释来确定的,而其绝对构型则是通过手性HPLC和CD光谱的结合来分析的。变色素X(1)和C(3)在S / G2 / M期阻止了HeLa / Fucci2细胞的细胞周期进程。
