A new a-pyrone metabolite from a mangrove plant endophytic fungus, Fusarium sp.

摘要

A new cr-pyrone derivative, compound 2, and a known one, cladobotrin V, were isolated from the culture broth of the mangrove endophyte Fusarium sp. IM-37. Their structures were determined spectroscopically and compared with previously reported spectral data. Compound 2 restored the growth inhibition caused by hyperactivated Ca2+-signaling in mutant yeast.
