Methylation of Gibberellins by Arabidopsis GAMT1 and GAMT2[W]
It is shown that GAMT1 expression is also localized mostly to seed, suggesting a role in seed development and suggesting that the mature mutant seeds contained higher levels of active GAs than wild-type seeds. Expand
Inactive Methyl Indole-3-Acetic Acid Ester Can Be Hydrolyzed and Activated by Several Esterases Belonging to the AtMES Esterase Family of Arabidopsis1[W][OA]
MeIAA is an inactive form of IAA, and the manifestations of MeIAA in vivo activity are due to the action of free IAA that is generated from Me IAA upon hydrolysis by one or more plant esterases. Expand
Characterization of a petunia acetyltransferase involved in the biosynthesis of the floral volatile isoeugenol.
Biochemical characterization of the protein encoded by this gene showed that it has acetyltransferase activity and is most efficient with coniferyl alcohol among the alcohol substrates tested, supporting the conclusion thatConiferyl acetate is the substrate of isoeugenol synthase. Expand
Iridoids from Scrophularia buergeriana attenuate glutamate‐induced neurotoxicity in rat cortical cultures
Results suggested that Harp and 8‐MCA‐Harp protected primary cultured neurons against glutamate‐induced oxidative stress primarily by acting on the antioxidative defense system and on glutamatergic receptors, respectively. Expand
Meso‐dihydroguaiaretic acid and licarin A of Machilus thunbergii protect against glutamate‐induced toxicity in primary cultures of a rat cortical cells
The results suggest that MDGA and licarin A significantly protect primary cultured neuronal cells against glutamate‐induced oxidative stress, via antioxidative activities. Expand
Neuroprotective lignans from the bark of Machilus thunbergii.
Isoguaiacin, meso-dihydroguaiaretic acid, licarin A and (+)-guaiacIn had significant neuroprotective activities against glutamate-induced neurotoxicity in primary cultures of rat cortical cells at concentrations ranging from 0.1 microM to 10.0 microM. Expand
KD-501, a standardized extract of Scrophularia buergeriana has both cognitive-enhancing and antioxidant activities in mice given scopolamine.
It could be postulated that KD-501 may exert its potent cognitive-enhancing activity through both anti-acetylcholinesterase and antioxidative actions. Expand

The present study shows that induction of capsidiol production in the C. annuum is mediated by PLA2 activation. Expand
Articles : Quantitative Analysis of Compounds in Fermented Insampaedok-san and Their Neuroprotective Activity in HT22 Cells
Insampaedok-san is a traditional medicine used for the treatment of colds. We investigated several compounds in Insampeadok-san, and tested their neuroprotective and anti-oxidative activities afterExpand
meso-Dihydroguaiaretic acid attenuates the neurotoxic effect of staurosporine in primary rat cortical cultures
Results suggested that MDGA protected neuronal cells against staurosporine-induced apoptosis through the inhibition of Ca(2+) influx, cellular oxidation, cytochrome c release and caspase-3/7 activation. Expand
