Stictic acid is an aromatic organic compound, a product of secondary metabolism in some species of lichens.^[1]

Stictic acid is the subject of preliminary biomedical research. Stictic acid has cytotoxic and apoptotic effects in vitro .^[2] Computational studies suggest stictic acid may also stimulate p53 reactivation.^[3]
