Dihydropyrenophorin is a macrolide fungal metabolite and derivative of pyrenophorin originally isolated from D. avenae that has herbicidal and phytotoxic activities.1 It is herbicidal against S. halepense when used at a concentration of 0.065 µM. Dihydropyrenophorin is phytotoxic to a variety of agricultural crops, including barley, sorghum, wheat, and oats, as well as grasses, including goosegrass and Bermuda grass, in leaf puncture assays.

Antifungal metabolites from fungal endophytes of Pinus strobus
Phytochemistry 2011 Oct;72(14-15):1833-7.PMID:21632082DOI:10.1016/j.phytochem.2011.05.003
The extracts of five foliar fungal endophytes isolated from Pinus strobus (eastern white pine) that showed antifungal activity in disc diffusion assays were selected for further study. From these strains, the aliphatic polyketide compound 1 and three related sesquiterpenes 2-4 were isolated and characterized. Compound 2 is reported for the first time as a natural product and the E/Z conformational isomers 3 and 4 were hitherto unknown. Additionally, the three known macrolides; pyrenophorol (5), Dihydropyrenophorin (6), and pyrenophorin (7) were isolated and identified. Their structures were elucidated by spectroscopic analyses including 2D NMR, HRMS and by comparison to literature data where available. The isolated compounds 1, 2, and 5 were antifungal against both the rust Microbotryum violaceum and Saccharomyces cerevisae.
