Fly model of Alzheimer's disease tested with potentially bioactive viridins extracted from endolichenic fungi

Zhao Q, Chen GD, Feng XL, Yu Y, He RR, Li XX, Huang Y, Zhou WX, Guo LD, Zheng YZ, Yao XS, Gao H. Nodulisporiviridins A-H, Bioactive Viridins from Nodulisporium sp. J Nat Prod. 2015 Jun 26;78(6):1221-30. PMID: 25978520.

From the abstract: "Eight new viridins, nodulisporiviridins A-H (1-8), were isolated from the extract of an endolichenic fungal strain Nodulisporium sp. (No. 65-17-2-1) that was fermented with potato-dextrose broth. ... The short-term memory assay on an Aβ transgenic drosophila model of Alzheimer's disease showed that all eight compounds improved the short-term memory capacity, with potencies close to that of the positive control (memantine)."
