Two new indole diterpene derivatives, 5-hydroxy--aflatrem () and 14-hydroxy--aflatrem (), along with one known analogue, 14-(,-dimethl--valyloxy)paspalinine (), were isolated from the fermentation broth of the fungus sp. PQJ-1 derived from . The structures of the new compounds were elucidated from spectroscopic data and ECD spectroscopic analyses. All the compounds (-) were evaluated for their cytotoxicity against A549, Hela, Hep G2, and MCF-7 cell lines. Compounds and exhibited selective inhibition against Hela cells. Further studies showed that significantly induced apoptosis and suppressed migration and invasion in Hela cells. Moreover, could up-regulate pro-apoptotic genes BAX and Caspase-3 and down-regulate anti-apoptotic genes Bcl-xL and XIXP.
从采自 的真菌 sp. PQJ-1 的发酵液中分离得到了两个新的吲哚二萜衍生物，5-羟基--黄曲霉毒素 () 和 14-羟基--黄曲霉毒素 ()，以及一个已知类似物 14-(-，-二甲- -缬氨酰氧基)巴卡丁 (). 新化合物的结构通过光谱数据和 ECD 光谱分析阐明。所有化合物 (-) 都对 A549、Hela、Hep G2 和 MCF-7 细胞系进行了细胞毒性评估。化合物 和 对 Hela 细胞表现出选择性抑制作用。进一步的研究表明， 能显著诱导 Hela 细胞凋亡，并抑制其迁移和侵袭。此外， 可上调促凋亡基因 BAX 和 Caspase-3，下调抗凋亡基因 Bcl-xL 和 XIXP。
