The metabolites, compounds A-E, were isolated from a toxic strain of Aspergillus candidus and the structures of the characteristic cytotoxic compounds A (terphenyllin) and E (deoxyterphenyllin) were elucidated to p-terphenyl derivatives (1 and 24) by spectral data, oxidation reactions, and synthesis of compound A trimethyl ether. The cytotoxicity of the compounds and the derivatives was also discussed.
通过光谱数据、氧化反应和化合物 A 三甲基醚的合成,阐明了特征性细胞毒性化合物 A(三苯乙烯)和 E(脱氧三苯乙烯)的结构,即对三苯乙烯衍生物(1 和 24)。此外,还讨论了这些化合物及其衍生物的细胞毒性。
