title: Synthesis and biodistribution of radioarsenic labeled dimethylarsinothiols: derivatives of penicillamine and mercaptoethanol.
abstract: Arsenic analogs of sulfhydryl containing biomolecules can be derived from dimethylchloroarsine as a precursor. Arsenic-76 labeled dimethylarsinothiols (dimethylarsinopenicillamine and dimethylarsinomercaptoethanol) were synthesized, purified by chromatography, and their biodistributions obtained in mice. The present study demonstrates the possibility of developing a group of radioarsenicals from SH-containing biomolecules.
