Inactivity of 3-methyleneoxindole as mediator of auxin action on cell elongation.
The recently reported growth-promoting ability of 3-methyl-eneoxindole was examined in order to test the hypothesis that indole-3-acetic acid acts as a growth promoter only after oxidative conversion to 3-methyleneoxindole. Methyleneoxindole was synthesized from indole-3-acetic acid and N-bromosuccinimide, and its identity was confirmed by ultraviolet absorption, infrared absorption, mass spect...
متن کامل3-Methyleneoxindole reductase of peas.
A 100-fold purification of a reduced triphosphopyridine nucleotide/3-methyleneoxindole reductase of peas has been achieved using conventional protein fractionation procedures. Reduced diphosphopyridine nucleotide is 25-fold less effective than reduced triphosphopyridine nucleotide as the reductant. The preparation is free of other reductase activities including those linking the oxidation of re...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولInhibition of cellular and viral protein synthesis by 3-methyleneoxindole.
The effect of 3-methyleneoxindole (MO) on mengovirus and L-cell protein synthesis was investigated. MO was found to inhibit mengovirus multiplication and the incorporation of radioactive amino acids into both viral and cellular proteins. These results suggest that the antiviral effect of this compound is not specific but rather stems from its inhibition of the cellular translational machinery u...
متن کاملAuxin Activity of Isatin and Oxindole-3-Acetic Acid.
Most workers have found that oxindoles are inactive as auxins or as auxin antagonists. For example, Thimann (44) working with straight growth of Az'ena coleoptile cylinders anid Pisitm stem sectiolns, and with growth curvature of slit Pistni stem sections, found the following 6 compounds to be without effect at concentraticns up to 30 mg/liter, both in the absence and presence of IAA at concent...
