Two new annonaceous acetogenins squamocin P (2) and annosquatin III (3) and one new ACG precursor dieporeticenin B (1) along with five known precursors (4-8) were isolated from the seeds of Annona squamosa. Their structures were ascertained by chemical methods and various spectral evidences. These compounds showed inhibitory effects against three multidrug-resistant (MDR) cancer cell lines. Compound 2 and 3 displayed selective cytotoxicity against SMMC 7721/T (IC 0.435 and 1.79 μM) and MCF-7/ADR (IC values 3.34 and 4.04 μM).
从番荔枝种子中分离出两种新的番荔枝乙酰精宁——鳞精宁P(2)和番荔枝鳞精三(3),以及一种新的乙酰精宁前体——二氢番荔枝宁B(1),同时还分离出了五种已知的前体(4 - 8)。通过化学方法和各种光谱证据确定了它们的结构。这些化合物对三种多药耐药(MDR)癌细胞系显示出抑制作用。化合物2和3对SMMC 7721/T(IC值分别为0.435和1.79 μM)和MCF - 7/ADR(IC值分别为3.34和4.04 μM)表现出选择性细胞毒性。
