cantharidin was first isolated by pierre robiquet in 1810. it is an odorless and colorless solid at room temperature. it is secreted by the male blister beetle and given to the female during the mating. afterwards the female beetle will cover its eggs with it as a defense against predators. the complete mechanism of the biosynthesis is currently unknown. if cantharidin is ingested, it severely irritates the urinary tract as it is excreted, causing swelling of the genitalia. this can cause a harmful condition known as priapism in men, where an erection lasts more than about four hours.
1. cantharidin (cas no.56-25-7) is used in biochemical research, clinically as antineoplastic agents, mainly for primary liver cancer, it is often used in conjunction with other antineoplastic agents.
2. cantharidin (cas no.56-25-7) is used as hydroxycanthayridimide intermediates.
