    Product Description

    Mecysteine is a methyl ester form of the conditionally essential amino acid L-cysteine (Item No. 33309). It increases the output of respiratory tract fluid in anesthetized dogs when administered at doses of 30 and 100 mg/kg.1 Mecysteine has also been used in the synthesis of free fatty acid receptor 2 (FFAR2/GPR43) agonists.2 Formulations containing mecysteine have been used in the treatment of chronic obstructive pulmonary disease (COPD) and chronic bronchitis.
