Abstract
In this report, we disclose our discovery of a new antifungal natural product, sakurafusariene (1), from an in-house fractionated library of the culture broth of Fusarium sp. FKI-7550 strain by using a combination strategy of multidrug-sensitive yeast and chemical modification. Throughout our investigation, we encountered challenges in the isolation of natural product 1. A chemical modification strategy via alkylation of 1 allowed for removal of the impurities enabling us to elucidate the structure of 1. Furthermore, we synthesized ester derivatives using a method inspired by the isolation study of 1, which gave us valuable information to understand a preliminary structure-activity relationship against Pyricularia oryzae growth inhibitory activity.
