isolated from the sea hare Aplysia kurodai together with the congeners aplyronines B (3) and C (4). The absolute stereostructure of aplyronine A (2) was determined by the instrumental analysis (mainly NMR and MS) and the enantioselective synthesis of the fragments obtained from chemical degradation of aplyronine A (2). The structures of aplyronines B (3) and C (4) were also elucidated. Cytotoxicity and
从海兔Aplysia kurodai中分离到了一种有效的抗肿瘤大环内酯-Aplyronine A(2),以及同类的aplyronines B(3)和C(4)。通过仪器分析(主要是NMR和MS)和对苯丙氨酸A(2)的化学降解获得的片段的对映选择性合成,确定了苯丙氨酸A(2)的绝对立体结构。还阐明了鸭绿素B(3)和C(4)的结构。肾上腺素A(2)的细胞毒性和抗肿瘤活性进行了评估。
