Redox Behaviour of Verbascoside and Rosmarinic Acid

Combinatorial Chemistry & High Throughput Screening, 2013
The electrochemical oxidation mechanisms of rosmarinic acid (RA) and verbascoside (VB), both caffeic acid esters with two catechol moieties, were investigated. The redox mechanism is associated with the oxidation of the catechol groups, and was studied over a wide pH range by cyclic, differential pulse and square wave voltammetry, using a glassy carbon

Antiinflammatory effects in THP‐1 cells treated with verbascoside

Phytotherapy Research, 2010
AbstractVerbascum thapsus commonly known as ‘mullein’ is part of a large family of Scrophulariaceae consisting of more than 360 species. From antiquity Verbascum thapsus has been used as a medicinal herb, it contains diverse polysaccharides, iroid glycosides, flavonoids, saponins, volatile oils and phenylentanoids. Inducible nitric oxide synthase (iNOS)

Iridoids and verbascoside in callitrichaceae, hippuridaceae and lentibulariaceae

Phytochemistry, 1994
Abstract Callitriche stagnalis (Callitrichaceae), Hippuris vulgaris (Hippuridaceae), Pinguicula moranensis and Utricularia vulgaris (both Lentibulariaceae) have been investigated for iridoid glucosides and verbascoside or similar compounds.

Anti-Sports Anaemia Effects of Verbascoside and Martynoside in Mice

International Journal of Sports Medicine, 2010
This paper aims to investigate the effects of verbascoside and martynoside isolated from PEDICULARIS DOLICHOCYMBA on sports anaemia. Forty mice were divided into four groups: Group R (control group, nonsupplemented and maintained at rest), Group E (nonsupplemented and undergoing exercise), Group VE (supplemented with verbascoside 10 mg/kg per day and ...

Mode of Action of Buddleja cordata Verbascoside Against Staphylococcus aureus

Journal of Ethnopharmacology, 1999
We evaluate the mode of action of verbascoside obtained from Buddleja cordata against Staphylococcus aureus by killing kinetics and incorporation of precursors methods. Verbascoside induced lethal effect on S. aureus, by affecting protein synthesis and inhibiting leucine incorporation.

Verbascoside Alleviates Pneumococcal Pneumonia by Reducing Pneumolysin Oligomers

Molecular Pharmacology, 2016
Pneumolysin (PLY), an essential virulence factor of Streptococcus pneumoniae (pneumococcus), can penetrate the physical defenses of the host and possesses inflammatory properties. The vital role PLY plays in pneumococcus pathogenesis makes this virulence factor one of the most promising targets for the treatment of pneumococcal infection. Verbascoside (

Verbascoside derivatives and iridoid glycosides from Penstemon crandallii

Phytochemistry, 1995
The new phenylethanoid glycosides 2-O-acetyl-3'''-O-methylverbascoside and 2,4"-di-O-acetyl-3'''-O-methylverbascoside were isolated and identified from Penstemon crandallii. The major iridoid glycoside was plantarenaloside and no aucubin type iridoids were found. This contrasted with a previous analysis of P.

Anti-Tumor Activity of Verbascoside Loaded Gold Nanoparticles

Journal of Biomedical Nanotechnology, 2014
Verbascoside (VB), a major bioactive constituent of the Tsoong herb, has attracted a great deal of attention due to its pharmacological properties. In this study, we demonstrated the inhibitory effect of VB-loaded gold nanoparticles (VB-Au) on the growth of K562 cells both in vitro and

Effect and mechanism of verbascoside on hypoxic memory injury in plateau

Phytotherapy Research, 2019
Verbascoside is a water‐soluble natural phenylethanoid glycoside and distributes widely in plants. It has been proved with antioxidant, neuroprotective, anti‐inflammatory, antibacterial, and immunomodulatory bioactivities. In this experiment, the effect and mechanism of verbascoside on hypoxic memory injury were studied in a low‐pressure and low‐oxygen

Synthesis of Verbascoside: A Dihydroxyphenylethyl Glycoside with Diverse Bioactivity

European Journal of Organic Chemistry, 1999
TMSOTf-mediated condensation of ethyl 4,6-O-benzylidene-1-thio-β-D-glucopyranoside (2) with peracetylated α-L-rhamnopyranosyl trichloroacetimidate donor 3a resulted in the formation of orthoester 4, which, after acetylation, rearranged into ethyl 3-O-(α-L-rhamnopyranosyl)-1-thio-β-D-glucopyranoside derivative 6a.
