Abstract
A compound of the following formula: ##STR1## wherein X.sub.1 is hydrogen or mercapto; X.sub.2 is mercapto or acetylthio; X.sub.3 is hydrogen or acetylthio; and X.sub.4 is hydrogen, acetylthio or X.sub.3 and X.sub.4 together form a valence bond, but if X.sub.3 and X.sub.4 form a valence bond X.sub.2 is mercapto. The compounds are useful in the treatment of heavy-metal poisoning.
