From Phomopsis sp. (68-GO-164) six new cytochalasans named cytochalasins N, O, P, Q, R and S were isolated, together with the four known compounds, epoxycytochalasins H and J and cytochalasins H and J. The structures (5 – 10) of the new compounds as 10-phenyl-[11]cytochalasans were determined from spectral data, especially 1H and 13C NMR, and by chemical correlation with known compounds. Cytochalasins
从Phomopsis sp。(68-GO-164)6个名为细胞松弛素N,O,P,Q,R和S中分离新cytochalasans,与四个已知的化合物一起,epoxycytochalasins H和J和细胞松弛素H和J的结构(5 - 10)根据光谱数据,特别是1 H和13 C NMR,以及与已知化合物的化学相关性,确定了新化合物的10-苯基-[11]细胞松弛素。细胞松弛素P,Q,R和S(7 - 10)具有在分子中的环己烷部分新颖二醇型结构。
