MSH: 3-Mercapto-D-valine. The most characteristic degradation product of the penicillin antibiotics. It is used as an antirheumatic and as a chelating agent in Wilson's disease.,CSP: beta dimethyl analog of cysteine; USP lists as a chelating agent.,NCI: A drug that removes copper from the body and is used to treat diseases in which there is an excess of this metal. It is also being studied as a possible angiogenesis inhibitor in brain tumors.,PDQ: A beta dimethyl analog of the amino acid cysteine. As a degradation product of penicillin antibiotics, penicillamine chelates with heavy metals and increases their urinary excretion. Possessing antineoplastic properties, penicillamine induces apoptosis by a p53-mediated mechanism and inhibits angiogenesis by chelating with copper, a cofactor for angiogenesis.
