Cantharidin Chemical Properties,Usage,Production

Description

Cantharidin is a natural toxicant of blister beetles. Cantharidin has been used as a medicinal agent for over 2000 years and is listed as a drug under the name of Mylabris in the medical monograph Materia Medica published in 77 AD. Some of the most ancient Chinese prescriptions (306–168 BC) refer to the use of Mylabris for the treatment of furuncles and piles.
Cantharidin can be used for topically (0.7%) treatment of warts, in which the skin under the wart blisters, thereby, lifting the wart off the skin. It is used to treat molluscum contagiosum. Cantharidin is a strong inhibitor of protein phosphatases types 1 (PP1) and 2A (PP2A), which are potentially novel targets for anticancer therapies. Thus, cantharidin is exploited as anticancer drugs. Cantharidin is shown to be cytotoxic to cancer cells and stimulatory on the bone marrow. The renal toxicity of this drug has prevented its use in mainstream oncology.

Uses

Cantharidin (Cantharone), a mitochondrial poison derived from the blister beetle Cantharis vesicatoria, leads to changes in cell membranes, epidermal cell dyshesion, acantholysis, and blister formation and is also useful. Cantharidin can be compounded with salicylic acid and podophyllin resin; occlusion for only 2 hours is needed with this combination. Thick hyperkeratotic lesions should be pared down before painting. The lesion should then be painted with cantharidin, allowed to dry, and covered with Blenderm or other nonporous occlusive tape; 40% salicylic acid plaster may be used to achieve greater activity. The tape is left on for 24 hours or until the area begins to hurt. A blister, often hemorrhagic, will form, break, crust, and fall off in 7 to 14 days; at this time, the lesion is pared down, and any wart remnants are retreated. Because the effect of cantharidin is entirely intraepidermal, no scarring ensues. Ring-like or 'donut configuration' recurrences may be seen occasionally after treatment with cantharidin or, at times, following liquid nitrogen therapy. Owing to this agent’s toxicity, application by a physician is recommended. Verrusol, which contains 30% salicylic acid, 5% podophyllin, and 1% cantharidin, may be used in the same manner.

Description

Cantharidin (56-25-7) inhibits protein phosphatase 2A (Ki=0.19 μM) and PP1 (Ki=1.1 μM).1 Displays >500-fold selectivity over PP2B. Suppresses growth and migration of PANC-1 pancreatic cancer cells via phosphorylation and degradation of β-catenin.2?Cantharidin arrests G2/M transition via JNK/Sp1-dependent down-regulation of CDK1.3?Cell permeable. Warning: Avoid skin contact, may cause skin irritation or blistering.

Chemical Properties

Cantharidin is a brown to black powder.

Chemical Properties

white to light yellow crystal powde

Uses

Cantharidin is a natural toxin produced by blister beetles that moderately inhibits protein phosphatases 1 (PP1) (IC50 = 1.7 μM) and PP2A (IC50 = 0.2 μM) and only weakly inhibits the activity of PP2B (IC50 = 1 mM). It has been shown to stimulate cell cycle progression and induce premature mitosis, used topically (0.7%) as an anti-wart treatment, and has been shown to be active in cervical, tongue, neuroblastoma, bone, leukemia, ovarian, colon, and various other cancer cell lines.

Uses

Cantharidin is used as a potent inhibitor of PP2A phosphatase activity. It has been shown to stimulate cell cycle progression and induce premature mitosis, used topically (0.7%) as an anti-wart treatment, and has been shown to be active in cervical, tongue, neuroblastoma, bone, leukemia, ovarian, colon, and various other cancer cell lines.

Uses

In veterinary medicine as a vesicant, rubefa- cient, and counterirritant.

Definition

ChEBI: A monoterpenoid with an epoxy-bridged cyclic dicarboxylic anhydride structure secreted by many species of blister beetle, and most notably by the Spanish fly, Lytta vesicatoria. Natural toxin inhibitor of protein phosphatases 1 and 2A.

Indications

Cantharidin, from the beetle Cantharis vesicatoria, causes intraepidermal vesiculation and is used in the treatment of warts and other benign cutaneous lesions. Cantharidin is extremely toxic if taken internally; it should not be prescribed for at-home use.

General Description

Brown to black powder or plates or scales. Formerly used as a counterirritant and vesicant. Used for the removal of warts. Used as an experimental anti tumor agent. Active ingredient in spanish fly, a reputed aphrodisiac.

Reactivity Profile

Organic anhydrides, such as Cantharidin, are incompatible with acids, strong oxidizing agents, alcohols, amines, and bases.

Hazard

Extremely toxic; questionable carcinogen; powerful irritant to all cells and tissues; deadly poi- son; respiratory failure; death.

Health Hazard

Cantharidin is classified as super toxic. Probable oral lethal dose in humans is less than 5 mg/kg or a taste of less than 7 drops for a 70 kg (150 lb.) person. It is very toxic by absorption through skin.
