Anti-inflammatory and antioxidant activities of constituents isolated from Pueraria lobata roots.[Pubmed:22644850]
Arch Pharm Res. 2012 May;35(5):823-37.
In order to evaluate the anti-inflammatory and antioxidant activities of Pueraria lobata roots and its active components, in vitro inhibitory activities against lipopolysaccharide (LPS)-induced nitric oxide (NO) production, inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) protein expression, and tert-butylhydroperoxide (t-BHP)-induced reactive oxygen species (ROS) generation in RAW 264.7 cells, as well as in vitro scavenging activities against 1,1-diphenyl-2-picrylhydrazyl (DPPH), peroxynitrite (ONOO(-)), nitric oxide (NO.), superoxide anion (.O(2)(-)) and total ROS, and inhibitory activities against ONOO(-)-mediated tyrosine nitration, were determined. Repeated column chromatography was performed to isolate four known compounds from the anti-inflammatory and antioxidant EtOAc fraction: daidzein; genistein; puerarin; (+)-puerarol B-2-O-glucopyranoside; four known compounds from the anti-inflammatory n-hexane fraction: lupenone; lupeol; puerarol; coumestrol; seven known compounds from the antioxidant n-BuOH fraction: allantoin; 3'-hydroxypuerarin; daidzein 8-C-apiosyl-(1-->6)-glucoside; puerarin; genistin; 3'-methoxypuerarin; daidzin. Among these compounds, lupenone and lupeol reduced NO production, as well as iNOS and COX-2 protein levels in LPS-stimulated RAW 264.7 cells. Furthermore, lupeol showed significant inhibitory activity against intracellular ROS generation by t-BHP. Meanwhile, 3'-hydroxypuerarin showed marked ONOO(-), NO., total ROS scavenging activities, and weak .O(2)(-) scavenging activity, while 3'-methoxypuerarin showed ONOO(-) scavenging activity and weak NO. and O(2)(-) scavenging activities, suggesting that existence of the 3'-hydroxyl group in puerarin plays an important role in the scavenging of ONOO(-), NO., and total ROS, as well as inhibiting the ONOO(-)-mediated tyrosine nitration mechanism. These results indicate that P. lobata roots and its constituents may be a useful therapeutic and preventive approach to various inflammatory diseases and oxidative stress-related disease.
Protection by 3'-methoxypuerarin of rat hippocampal neurons against ischemia/reperfusion injury.[Pubmed:21793321]
Chin J Physiol. 2010 Apr 30;53(2):136-40.
3'-Methoxypuerarin (3'-MOP) is an isoflavone extracted from radix puerariae. The aim of this study was to investigate the role and the mechanism of 3'-MOP in the protection of hippocampal neurons against cerebral ischemia/reperfusion (I/R) injury in rats. I/R injury was induced by a modified four-vessel occlusion model. Rats were randomly divided into an I/R group, an I/R + 3'-MOP group and a control group. Histological changes in the neurons of the hippocampal CA1 region were observed with hematoxylin and eosine (H&E) staining. The apoptotic neurons in the hippocampal CA1 area were counted with the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining. The results showed that compared with the I/R group, 3'-MOP increased the number of surviving neurons in the hippocampal CA1 region (P < 0.001) and markedly reduced the number of apoptotic pyramidal neurons (P < 0.001) after I/R injury. In conclusion, 3'-MOP can protect hippocampal neurons against I/R injury by inhibiting apoptosis.
