Elucidation of the Structure and Synthesis of Neuroprotective Low Molecular Mass Components of the Parawixia bistriata Spider Venom

The South American social spider Parawixia bistriata produces a venom containing complex organic compounds with intriguing biological activities. The crude venom leads to paralysis in termites and stimulates l-glutamate uptake and inhibits GABA uptake in rat brain synaptosomes. Glutamate is the major neurotransmitter at the insect neuromuscular junction and at the mammalian central nervous system, suggesting a modulation of the glutamatergic system by the venom. Parawixin1, 2, and 10 (Pwx1, 2 and 10) are HPLC fractions that demonstrate this bioactivity. Pwx1 stimulates l-glutamate uptake through the main transporter in the brain, EAAT2, and is neuroprotective in in vivo glaucoma models. Pxw2 inhibits GABA and glycine uptake in synaptosomes and inhibits seizures and neurodegeneration, and Pwx10 increases l-glutamate uptake in synaptosomes and is neuroprotective and anticonvulsant, shown in in vivo epilepsy models. Herein, we investigated the low molecular mass compounds in this venom and have found over 20 small compounds and 36 unique acylpolyamines with and without amino acid linkers. The active substances in fractions Pwx1 and Pwx2 require further investigation. We elucidated and confirmed the structure of the active acylpolyamine in Pwx10. Both fraction Pwx10 and the synthesized component enhance the activity of transporters EAAT1 and EAAT2, and, importantly, offer in vitro neuroprotection against excitotoxicity in primary cultures. These data suggest that compounds with this mechanism could be developed into therapies for disorders in which l-glutamate excitotoxicity is involved.

A substituted indole -3 - acetic acid synthesis method (by machine translation)

The present invention provides a substituted indole - 3 - acetic acid synthesis method, comprises the following steps: (1) in order to replace the indole as the starting material, with the acylation reagent under the action of catalyst through the tutor - acylation to obtain the 1, 3 - diacetyl substituted indole; (2) intermediate 1, 3 - diacetyl substituted indole does not need refining, directly with the morpholine and sulfur by the Willgerodt - Kindler rearrangement reaction, the inorganic under the catalysis of alkali hydrolysis, acidified to obtain substituted indole - 3 - acetic acid.

Three oxidative metabolites of indole-3-acetic acid from Arabidopsis thaliana

Three metabolites of indole-3-acetic acid (IAA), N-(6-hydroxyindol-3-ylacetyl)-phenylalanine (6-OH-IAA-Phe), N-(6-hydroxyindol-3-ylacetyl)-valine (6-OH-IAA-Val), and 1-O-(2-oxoindol-3-ylacetyl)-β-d-glucopyranose (OxIAA-Glc), were found by a liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS)-based search for oxidative IAA metabolites during the vegetative growth of Arabidopsis. Their structures were confirmed by making a comparison of chromatographic characteristics and mass spectra between naturally occurring compounds and synthetic standards. An incorporation study using deuterium-labeled compounds showed that 6-OH-IAA-Phe and 6-OH-IAA-Val were biosynthesized from IAA-Phe and IAA-Val, respectively, which strongly suggested the formation of these amino acid conjugates of IAA in plants. Both 6-OH-IAA-Phe and 6-OH-IAA-Val were inactive as auxins, as indicated by no significant root growth inhibition in Arabidopsis. Quantitative analysis demonstrated that OxIAA-Glc was present in the largest amount among the metabolites of IAA in Arabidopsis, suggesting that the conversion into OxIAA-Glc represents the main metabolic process regarding IAA in Arabidopsis.
