Synthesis and spectral studies of natural chlorins having antioxidative activity
Starting from pheophorbide a methyl ester (l), a degradation product of chlorophyll a, novel natural antioxidants of chlorophyll a related chlorins 3, 5(S), S(R), 8(R), 9-13 have been synthesized in high yields. Key steps involve formation of 5(R) and 5(S) via a DBU-promoted asymmetric hydroxylation of 3, and regioselective periodate oxidations of 5 to 8(R) and 9. Since photosynthetic organisms...
متن کاملAntioxidative Activity of Sixty Plants from Iran
Antioxidants are vital substances which possess the ability to protect the body from damage caused by free radical-induced oxidative stress. A variety of free radical scavenging antioxidants exist within the body which many of them are derived from dietary sources like fruits, vegetables and teas. This article describes a test method for screening the antioxidant activity of 60 Iranian plant...

متن کاملAntioxidative Activity of Melia Azedarach Linn Leaf Extract
The antioxidant activity of the melia azedarach was investigated in rats with ethanol-induced erythrocyte damage. Chronic administration of ethanol (20% w/v, 2 g/kg.p.o.,daily for four weeks) increased the level of lipid peroxidation (LPO), decreased the activity of superoxide dismutase (SOD) and catalase and reduced the content of glutathione (GSH). The concurrent treatment of ethanol-admini...
متن کاملNew aminophosphonates with antioxidative activity.
The antioxidative activity of some newly synthesized aminomethanephosphonic acid derivatives was studied. The compounds studied differed in their polarity and the hydrophobicity of the electronic substituents at their nitrogen and phosphorus atoms. It was found that all the aminophosphonates studied, both cyclic and acyclic, protected erythrocyte membranes against peroxidation to some extent. T...
