Methylmercury complexes of the most widely studied antidotes for mercury poisoning have been prepared, and both the water solubility and l-octanol/water partition coefficients determined for these complexes and the L-cysteine complex. New complexes of N-acetyl-D,L-penicillamine, 2-mercaptosuccinic acid, meso-dimercaptosuccinic acid, and Unithiol have been synthesized and characterized, and are found to have the formulations MeHgSCMe2CH(NHCOMe)CO2H, MeHgSCH(CO2H)CH2CO2H, MeHgSCH(CO2H)CH(CO2H)SHgMe, and Na[MeHgSCH2CH(SHgMe)CH2SO3)], respectively. Trends in octanol/water partition coefficients are consistent with reported studies of the effectiveness of antidotes for methylmercury poisoning and redistribution of methylmercury) on administration of antidotes, particularly for British anti-Lewisite, Unithiol, and meso-dimercaptosuccinic acid.
