Dimercaprol (2, 3-dimercapto-1-propanol) or British anti-Lewisite (BAL), is a colorless or almost colorless liquid chelating agent having a disagreeable, mercaptan-like odor. Dimercaprol was developed at Oxford University during World War II as a means of treating and reversing poisoning from Lewisite, an arsenical gas used in chemical warfare (and thus initially called British anti-Lewisite [BAL]). The sulfhydryl groups of dimercaprol form complexes with certain heavy metals thus preventing or reversing the metallic binding of sulfhydryl-containing enzymes. Parenterally administered dimercaprol is used to treat arsenic, gold, copper and mercury poisoning. It is indicated in acute lead poisoning when used concomitantly with edetate clcium disodium. Dimercaprol is occasionally used in the initial treatment of severe, symptomatic Wilson disease, but generally for a short time only.

Conditions:
Trientine, also known as triethylenetatramine or abbreviation TETA, is a highly selective divalent Cu(II) chelator and orphan drug that reverses copper overload in tissues. It was approved as second-line pharmacotherapy for Wilson's disease. Wilson's disease (hepatolenticular degeneration) is an autosomal inherited metabolic defect resulting in an inability to maintain a near-zero balance of copper. Excess copper accumulates possibly because the liver lacks the mechanism to excrete free copper into the bile. Hepatocytes store excess copper but when their capacity is exceeded copper is released into the blood and is taken up into extrahepatic sites. This condition is treated with a low copper diet and the use of chelating agents that bind copper to facilitate its excretion from the body. Although penicillamine treatment is believed to be more extensive, TETA therapy has been shown to be an effective initial therapy. In addition, TETA is in a clinical trial phase II for the prevention of the Macular Edema after Cataract Surgery. TETA is also considered a potential chemotherapeutic agent as it could be a telomerase inhibitor. Chelating excess copper may affect copper-induced angiogenesis. Other mechanisms of action of TETA for alternative therapeutic implications include improved antioxidant defense against oxidative stress, pro-apoptosis, and reduced inflammation.

Targets:
Penicillamine, sold under the trade names of Cuprimine among others, is a medication primarily used for treatment of Wilson's disease, cystinuria and active rheumatoid arthritis. Penicillamine is a chelating agent recommended for the removal of excess copper in patients with Wilson's disease. From in vitro studies which indicate that one atom of copper combines with two molecules of penicillamine. Penicillamine also reduces excess cystine excretion in cystinuria. This is done, at least in part, by disulfide interchange between penicillamine and cystine, resulting in formation of penicillamine-cysteine disulfide, a substance that is much more soluble than cystine and is excreted readily. Penicillamine interferes with the formation of cross-links between tropocollagen molecules and cleaves them when newly formed. The mechanism of action of penicillamine in rheumatoid arthritis is unknown although it appears to suppress disease activity. Unlike cytotoxic immunosuppressants, penicillamine markedly lowers IgM rheumatoid factor but produces no significant depression in absolute levels of serum immunoglobulins. Also unlike cytotoxic immunosuppressants which act on both, penicillamine in vitro depresses T-cell activity but not B-cell activity.
