Penicillamine occurs as pharmaceutical of the chelator class. These are sold under a brand of Cuprimine & Depen. A pharmaceutical form is D-penicillamine, when L-penicillamine is toxic (it inhibits a action of pyridoxine). These are the metabolite of penicillin, although it has no antibiotic properties.
Uses
Penicillamine is utilized as a form of immunosuppression to treat rheumatoid arthritis. It works by reducing many T-lymphocytes, inhibiting macrophage function, decreasing IL-1, decreasing rheumatoid factor, and preventing collagen from cross-linking.
Its have around Wilson's disease, a rare genetic disorder of copper metabolism, relies on its binding to accumulated copper and elimination through urine.
History
Dr John Walshe (1956) foremost described a apply of cuprimine around Wilson's disease. He got found a compound in the piddle of patients (including himself) world health organization experienced taken penicillin, and by experimentation confirmed that it increased urinary copper excretion by chelation. He experienced initial difficulty convincing many globe experts of the period (Drs Denny Red & Cumings) of its efficaciousness, when it held that Wilson's disease was non primarily the condition of copper homeostasis however of amino acid metabolism, & that dimercaprol should be utilized as a chelator. Late studies confirmed each a copper-centered theory & a efficaciousness of D-penicillamine. Walshe likewise pioneered more chelators within Wilson's like triethylene tetramine 2HCl and tetrathiomolybdate (Walshe 2003).
