Fusaric acid is a picolinic acid derivative.

Antibiotic (wilting agent) first isolated from the fungus Fusarium heterosporium.[1]

It is typically isolated from various Fusarium species, and has been proposed for a various therapeutic applications. However, it is primarily used as a research tool.

Its mechanism of action is not well understood. It likely inhibits Dopamine beta-hydroxylase (the enzyme that converts dopamine to norepinephrine). It may also have other actions, such as the inhibition of cell proliferation and DNA synthesis.

It is used to make bupicomide.
