Description
Lapachol is a naphthoquinone that was first isolated from Tabebuia avellanedae (Bignoniaceae). Lapachol shows anti-infection and antitumor activity[1]
Lapachol is a hydroxy-1,4-naphthoquinone that is 1,4-naphthoquinone substituted by hydroxy and 3-methylbut-2-en-1-yl groups at positions 2 and 3, respectively. It is a natural compound that exhibits antibacterial and anticancer properties, first isolated in 1882 from the bark of Tabebuia avellanedae. It has a role as a plant metabolite, an antineoplastic agent, an antibacterial agent and an anti-inflammatory agent. It is a hydroxy-1,4-naphthoquinone and an olefinic compound.

Drug Information
Substances that prevent infectious agents or organisms from spreading or kill infectious agents in order to prevent the spread of infection. (See all compounds classified as Anti-Infective Agents.)|Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues. (See all compounds classified as Antifungal Agents.)|Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly. (See all compounds classified as Antiviral Agents.)|Agents used in the treatment of malaria. They are usually classified on the basis of their action against plasmodia at different stages in their life cycle in the human. (From AMA, Drug Evaluations Annual, 1992, p1585) (See all compounds classified as Antimalarials.)|Agents obtained from higher plants that have demonstrable cytostatic or antineoplastic activity. (See all compounds classified as Antineoplastic Agents, Phytogenic.)|Agents that kill parasitic worms. They are used therapeutically in the treatment of HELMINTHIASIS in man and animal. (See all compounds classified as Anthelmintics.)
