N-acetyl-L-Cysteine amide (NACA) is a novel antioxidant, the amide form of N-acetylcysteine (NAC), due to its permeability through both cellular and mitochondrial membranes [1]. N-acetylcysteine amide permeates cellular and mitochondrial membranes, crosses the blood-brain barrier [1,2] and has higher radical scavenging ability, metal chelating activity and reducing power than NAC [3].
N-acetyl-L-Cysteine amide protects neurons and dopaminergic cells from oxidative stress in tissue cultures and lipid peroxidation in neuronal cell lines [4,5]. N-acetyl-L-Cysteine amide (750 µM) protected the PC12 cells from glutamate toxicity by slightly decreasing the bleb formation on neurites, and increased the PC12 cell GSH level [5]. N-acetyl-L-Cysteine amide protected PC12 cells against glutamate cytotoxicity by decreasing the glutamate-induced ROS accumulation [5]. N-acetylcysteine amide (1 mM) prevents METH-induced oxidative stress in human brain microvascular endothelial (HBMVEC) cells [6].
In moderate TBI, N-acetyl-L-Cysteine amide treatment improves mitochondrial bioenergetics, cognitive function, cortical tissue sparing and reduces lipid peroxidation product 4-hydroxynonenal compared to NAC or vehicle treated rats [7]. In acute spinal cord injury, N-acetyl-L-Cysteine amide (150 or 300 mg/kg/day) treatment improves mitochondrial bioenergetics, maintains mitochondrial glutathione and improves tissue sparing and hind limb function [8].
