MiADMSA
MiADMSA (Monoisoamyl meso-2,3-dimercaptosuccinic acid) is an orally active thiol chelator that can effectively remove heavy metals such as arsenic and lead from the body of animals. Arsenic binds with two vicinal sulfhydryl groups available in MiADMSA leading to marked reduction in body arsenic burden and also marked reduction in various oxidative stress parameters and antioxidant enzymes like-ROS, nitrite, TBARS, GSH, SOD and catalase. MiADMSA attenuates urinary bladder carcinogenesis, protects against oxidative stress, ameliorates copper-induced histopathology, reverses neurotoxicity, and is safe in animals. MiADMSA can be used in studies of bladder cancer, arsenic, and lead-induced developmental neurotoxicity.
