gamma-Pyrone-3-acetic acid (L-741,494) is a novel metabolite produced by a culture of the fungal genus Xylaria. This substance is a water-soluble, competitive, irreversible inhibitor of Interleukin-1 beta Converting Enzyme that is inactive against papain and trypsin. It has a mol wt of 154 and an empirical formula of C7H6O4. We propose the name xylaric acid for this compound.
