Mechanistic investigations on the previously reported reduction of B-alkylcatecholboranes in the presence of methanol led to the disclosure of a new mechanism involving catechol as a reducing agent. More than just revising the mechanism of this reaction, we disclose here the surprising role of catechol, a chain breaking antioxidant, which becomes a source of hydrogen atoms in an efficient radic...

the imbalance between pro-oxidants and anti-oxidants leads to generation of oxygen/nitrogen free radicals which are implicated in several neurodegenerative diseases. fagonia arabica is an ethno-pharmacologically important ayurvedic herb known to have many medicinal properties like anti-inflammatory, analgesic and antipyretic effects. however, its antioxidant potential has not been investigated ...

It would be desirable to establish and standardize methods that can measure the total antioxidant capacity level directly from vegetable extracts containing phenolics. Antioxidant capacity assays may be broadly classified as electron transfer (ET)- and hydrogen atom transfer (HAT)-based assays. The majority of HAT assays are kinetics-based, and involve a competitive reaction scheme in which ant...

Abstract Rosemary Oil ( Rosmarinus officinalis ) contains carnosic acid, carnosol, and rosmarinic which are sources of active antioxidants. The Secretome MSC has growth factors such as antioxidants that protect HDFs. This study aimed to obtain a gel formulation from secretome combinates with test its effect an antioxidant. antioxidant, propylene glycol humectants, Carbomer 940 gelling agent, tr...

BACKGROUND Administration of KA on rodents has resulted in seizures, behavioral changes, oxidative stress, and neuronal degeneration on selective population of neurons in the brain. The present study was undertaken to investigate the extent of neuroprotective effect conferred by Malaysian Tualang Honey (TH), an antioxidant agent, in the cerebral cortex of rats against KA-induced oxidative stres...

Vanilic Acid Article 2200431 by Markus Stöckl, Siegfried R. Waldvogel, and co-workers demonstrates a new method how to obtain selectively vanillic acid, flavouring agent antioxidant, from side-stream lignins degradation using electrochemically generated ferrate as oxidizer. In times of climate changes the utilization relevant bio-based lignin renewable feedstock for fine chemicals is considered...

Ceramide-based therapeutics have gained recent attention as anti-neoplastic therapeutics. These include standard of care therapeutics that in part exert efficacy through the generation of ceramide, as well as new therapeutics that seek to specifically deliver or augment ceramide levels in malignant cells. Ceramide is a bioactive sphingolipid involved in apoptotic and stress cellular signaling p...

this study was carried out to evaluate the antimicrobial and antioxidant effectiveness of different extracts from aerial parts of six salvia species including salvia ceratophylla, salvia chorassanica, salvia leriifolia, salvia macrosiphon, salvia chloroleuca and salvia virgata. the effect of the extracts against 3 gram positive and 3 gram negative bacteria was tested by the micro dilution metho...

The molecular properties of apigenin, luteolin and nevadensin which are three naturally flavonoid compounds have been studied theoretically by DFT method at 6-311++G(d,p) level. Both FMO analysis, mechanism, kinetics suggested that compound Luteolin (compound 3) was a promising antioxidant agent. results indicated HAT is thermodynamically preferred in the gas phase, SPLET favorable pathway meth...
