2-Methoxynaphthoquinone is a naturally occurring naphthalene derivative, first synthesized by L. Fieser in 1926, and afterward found in Impatiens balsamina (garden balsam). 2-Methoxynaphthoquinone possess antifungal activity. In vitro studies showed that compound inhibits Wnt signaling and suppresses the invasion of breast cancer cell lines, and is able to induce gastric adenocarcinoma necrosis.
