| Abstract:: |
| Objective For developing safe and effective anti-radiation new drugs, the effects of different lipoic acid amino acid salts on radiosensitivity were investigated.Methods The free radical scavenging ability of the above salts was evaluated in Fenton system. CCK-8 assay and flow cytometry assay were performed to evaluate the survival rate of L02 and apoptosis of AHH-1 after γ-ray irradiation, respectively. Results The lipoic acid arginine salt had the best ability of scavenging free radicals in Fenton system with an IC50 of 8.40 μmol/ml. The survival assay showed that lipoic acid amino acid salts had better stability and equal ability in radioprotection (P>0.05) compared with lipoic acid. The apoptosis assay indicated that all lipoic acid amino acid salts could inhibit radiation-induced apoptosis, where lipoic acid arginine salt was more effective (t=-6.67, P<0.01). Conclusions Lipoic acid arginine salt has good radioprotection effect on L02 and AHH-1 cells by scavenging free radicals. |
