Phenylethanoid Glycosides from Callicarpa nudiflora

Chemistry of Natural Compounds, 2020
A new phenylethanoid glycoside, named cis-alyssonoside (1), was isolated from the leaves of Callicarpa nudiflora, along with four known phenylethanoid glycosides (2–5). Their structures were determined on the basis of extensive spectroscopic analysis and comparison with literature data. The inhibitory effects on lipopolysaccharide induced nitric oxide (

Biodiversity of Phenylethanoid Glycosides

2002
Phenylethanoid glycosides are a group of natural products widely distributed in the plant kingdom, most of which have been isolated from medicinal plants, and their patterns of distrubition have been suggested to be valuable taxonomic markers. The most widely studied families are Scrophulariaceae, Oleaceae, Plantaginaceae, Lamiaceae and Orobanchaceae1 ...

Phenylethanoid glycosides from Prostanthera melissifolia

Phytochemistry, 1999
Abstract Six phenylethanoid glycosides were isolated from aerial parts of Prostanthera melissifolia, together with apigenin and ursolic acid. The glycosides were characterized by spectral methods as martynoside, isomartynoside, verbascoside, isoverbascoside, betonyoside F and isobetonyoside F, the latter being a new natural product.

Synthetic phenylethanoid glycoside derivatives as potent neuroprotective agents

European Journal of Medicinal Chemistry, 2015
Several phenylethanoid glycoside derivatives were designed and synthesized. Most of the synthetic compounds showed significant neuroprotective effects, including antioxidative and anti-apoptotic properties. Specifically, target compounds displayed potent effects against various toxicities such as H2O2 and 6-hydroxydopamine (6-OHDA) in PC12 cells. Among
