CR 1642 D是从哥斯达黎加雨林采集的青霉属内生分离物,通过高通量方法鉴定,以鉴定在肿瘤-基质相互作用的背景下具有增强的抗肿瘤活性的天然产物。生物测定引导的分离导致从CR 1642 D中鉴定出五种氧杂蒽酮(1-5)。在光谱分析的基础上,包括2D NMR实验,阐明了氧杂蒽酮二聚体戊并蒽酮A(1)和单体戊并蒽酮B(2)的结构。在存在和不存在骨髓基质细胞的情况下,针对一组肿瘤细胞系测试所有化合物。化合物3的活性最强,IC 50值为1~17 μM,在基质细胞存在下,其对肿瘤细胞系RPMI 8226的活性增强两倍(IC 50为1.2 μM,但无基质细胞时为2.4 μM)。
CR1642D, an endophytic isolate of Penicillium sp. collected from a Costa Rican rainforest, was identified through a high-throughput approach to identify natural products with enhanced anti-tumor activity in the context of tumor-stromal interactions. Bioassay-guided separation led to the identification of five xanthones (1-5) from CR1642D. The structures of the xanthone dimer penexanthone A (1) and monomer penexanthone B (2) were elucidated on the basis of spectroscopic analyses, including 2D NMR experiments. All of the compounds were tested against a panel of tumor cell lines in the presence and absence of bone marrow stromal cells. Compound 3 was the most active, with IC50 values of 1~17 μM, and its activity was enhanced two-fold against tumor cell line RPMI8226 in the presence of stromal cells (IC50 1.2 μM, but 2.4 μM without stromal cells).
