the seeds of Asimina triloba resulted in the isolation of asimitrin (1) and 4-hydroxytrilobin (2). Compound 1 represents an adjacent ring-hydroxylated bis-tetrahydrofuran (THF) acetogenin. Compound 2 has an adjacent bis-THF ring with two flanking hydroxyl groups and a alpha,beta-unsaturated gamma-lactone with a 4-hydroxyl group. Compounds 1 and 2 showed cytotoxic selectivity, with 100-10 000 times the
生物活性导向的三叶草种子的分馏导致分离出了asimitrin(1)和4-hydroxytrilobin(2)。化合物1代表相邻的环-羟基化的双-四氢呋喃(THF)产黄素。化合物2具有相邻的具有两个侧羟基的双THF环和具有4-羟基的α,β-不饱和γ-内酯。化合物1和2表现出细胞毒性选择性,对前列腺腺癌(PC-3)和结肠腺癌(HT-29)细胞系阿霉素的效力为100-10 000倍。
