N-Acetylcysteine amide

N-Acetylcysteine amide 是一種能透過細(xì)胞膜和血腦屏障的硫醇抗氧化劑和神經(jīng)保護(hù)劑，可降低 ROS 的產(chǎn)生。

生物活性

N-Acetylcysteine amide is a cell membranes and blood brain barrier permeant thiol antioxidant and neuroprotective agent, reduces ROS production.

體外研究(In Vitro)

N-Acetylcysteine amide shows no obvious effect on the viability of H9c2 cells treated with doxorubicin (DOX) at < 1 mM, but causes significant cytotoxicity at 10-20 mM. N-Acetylcysteine amide (750 μM) reduces the ROS levle and lipid peroxidation induced by DOX, and restores GSH/GSSG ratio and activities of antioxidant enzymes, such as catalase (CAT), gluthathione peroxidase (GPx), gluthathione reductase (GR)^[1]. N-Acetylcysteine amide (1 mM) protects the human brain microvascular endothelial (HBMVEC) from methamphetamine (METH)- induced cell death^[3].

體內(nèi)研究(In Vivo)

N-Acetylcysteine amide has increased CNS bioavailability. N-Acetylcysteine amide (150 mg/kg, i.p.) improves cortical sparing and functional outcome, reduces oxidative stress, improves mitochondrial bioenergetics, and maintains mitochondrial glutathione content following traumatic brain injury (TBI) in rats^[2].
