Lapachol is a 1,4-naphthoquinone that is isolated from the Bignoniaceae family. It has been reported to exert anti-inflammatory, antibacterial, and anticancer activities. However, the anticancer activity of lapachol and its molecular mechanisms against esophageal squamous cell carcinoma (ESCC) cells have
