四乙酰基-D-吡喃木糖,

1,2,3,4-Tetra-O-acetyl-D-xylopyranose is a molecule that is derived from D-xylose. It has been shown to inhibit the growth of fungi such as T. rubrum and L. candidum by acetylation of l-threonine at the C2 position. This molecule can be recycled and its inhibitory activity can be increased through acetylation of the hydroxymethyl group on the C4 position. The mechanism of inhibition is not known but it may be due to steric hindrance or peracylation.
