di·mer·cap·rol

(dī'mĕr-kap'rol),
A chelating agent, developed as an antidote for lewisite and other arsenical poisons. It acts by competing for the metal with the essential -SH groups in the pyruvate oxidase system of the cells and forms, with arsenic, a stable, relatively nontoxic cyclic compound, the metal having a greater affinity for it than for the -SH groups of the cell proteins; also used as an antidote for antimony, bismuth, chromium, mercury, gold, and nickel.
