compounds citrinin (1), phenol A acid (6), dihydrocitrinone (7) and dihydrocitrinin (8), together with a novel cytotoxic dimer, dicitrinin A (5). Dicitrinin A (5) was determined to be a dimerised artefact of the major co-metabolite citrinin, and its structure solved by spectroscopic analysis and chemical modification. Analysis of the products encountered during the controlled decomposition of citrinin led
澳大利亚青霉菌青霉菌分离物的固相发酵的详细化学分析返回了已知化合物柑桔素(1),酚A酸(6),二氢胞嘧啶酮(7)和二氢胞嘧啶素(8),以及新型的细胞毒性二聚体,桔霉素A (5)。Dicitrinin A(5)被确定为主要的共代谢型citrinin的二聚产物,其结构通过光谱分析和化学修饰得以解决。对在柑桔素的受控分解过程中遇到的产物的分析导致发现了另外的柑桔素二聚体,并勾画了连接所有单体和二聚体柑桔素降解产物的似乎可行的机理途径。
