Evaluation of phenolic contents and antioxidant activity of various solvent extracts of Sonchus asper (L.) Hill
BACKGROUND Sonchus asper (SA) is traditionally used for the treatment of various ailments associated with liver, lungs and kidneys. This study was aimed to investigate the therapeutic potential of nonpolar (hexane, SAHE; ethyl acetate, SAEE and chloroform, SACE) and polar (methanol, SAME) crude extracts of the whole plant. METHODS To achieve these goals, several parameters including free-radi...
متن کاملMolecular basis of sulfonylurea herbicide inhibition of acetohydroxyacid synthase.
Acetohydroxyacid synthase (AHAS) (acetolactate synthase, EC ) catalyzes the first step in branched-chain amino acid biosynthesis and is the target for sulfonylurea and imidazolinone herbicides. These compounds are potent and selective inhibitors, but their binding site on AHAS has not been elucidated. Here we report the 2.8 A resolution crystal structure of yeast AHAS in complex with a sulfonyl...
متن کاملProtective effects of Sonchus asper (L.) Hill, (Asteraceae) against CCl4-induced oxidative stress in the thyroid tissue of rats
BACKGROUND Sonchus asper (L.) Hill, (Asteraceae) is used in Pakistan as a traditional ("folk") medicine for the treatment of hormonal disorders and oxidative stress. The present study was aimed to evaluate the efficacy of Sonchus asper (L.) Hill, (Asteraceae) methanolic extract (SAME) on hormonal dysfunction in thyroid tissue after carbon tetrachloride (CCl4)-induced oxidative stress. METHODS...
متن کاملProtein trans-splicing to produce herbicide-resistant acetolactate synthase.
Protein splicing in trans has been demonstrated both in vivo and in vitro by biochemical and immunological analyses, but in vivo production of a functional protein by trans-splicing has not been reported previously. In this study, we used the DnaE intein from Synechocystis sp. strain PCC6803, which presumably reconstitutes functional DnaE protein by trans-splicing in vivo, to produce functional...
متن کاملResistance to Acetolactate Synthase-Inhibiting Herbicides in Annual Ryegrass (Lolium rigidum) Involves at Least Two Mechanisms.
WLR1, a biotype of Lolium rigidum Gaud. that had been treated with the sulfonylurea herbicide chlorsulfuron in 7 consecutive years, was found to be resistant to both the wheat-selective and the nonselective sulfonylurea and imidazolinone herbicides. Biotype SLR31, which became cross-resistant to chlorsulfuron following treatment with the aryloxyphenoxypropionate herbicide diclofop-methyl, was r...
