Product Description

Product name: L-Lysine-S-Carboxy Methyl-L-Cysteine Synonyme: L-Carbocysteine-Lysine, SCMC-Lys CAS#: 49673-81-6 Molecular Formula: C6H14N2O2.C5H9NO4S Specification: 98% Function: Carbocysteine lysine salt monohydrate (SCMC-Lys) is a well-known mucoactive drug whose therapeutic efficacy is commonly related to the ability of SCMC-Lys to replace fucomucins by sialomucins. The aim of this study was to determine if SCMC-Lys couldexert an anti-oxidant action by scavenging reactive oxygen intermediates (ROIs). Our results show that SCMC-Lys proved effective as a selective scavenger of hypochlorous acid (HOCl) and hydroxyl radical (OH.), this effect being related to the reactivity of the SCMC tioether group. The scavenger activity of SCMC-Lys was observed in free cellular system as well as in activated human polymorphonuclear neutrophils (PMNs). SCMC-Lys scavenger activity on HOCl was paralleled by a powerful protection from HOCl-mediated inactivation ofalpha1-antitripsin (alpha1-AT) inhibitor, the main serum
