Antimicrobial meroterpenoids from the endophytic fungus Penicillium sp. T2-8 associated with Gastrodia elata

Publication date: December 2016 Source:Phytochemistry Letters, Volume 18 Author(s): Rongting Duan, Hao Zhou, Yabin Yang, Hongtao Li, Jianwei Dong, Xiaozhan Li, Guangyi Chen, Lixing Zhao, Zhongtao Ding A new meroterpenoid preaustinoid D (1) and a new neogrifolin derivative dihydroxyneogrifolic acid (2), together with other five previously reported meroterpenoids (3-7) were isolated from the endophytic fungus Penicillium sp. T2-8 associated with Gastrodia elata. The structures were elucidated on the basis of spectroscopic data analyses. It was the first time that neogrifolin and its derivatives were isolated from microorganism. Some of these meroterpenoids exhibited obvious antimicrobial activities in the microdilution antimicrobial assays. Graphical abstract
