A new ecdysteroside, named lygodiumsteroside A, as well as a known ecdysteroside, were isolated from the roots of Lygodium japonicum (Thunb.) Sw. Their structures were identified by spectral and chemical methods.
Vascular endothelial growth factor receptor 2 (VEGFR2)-mediated signaling is the key rate-limiting step in angiogenesis. VEGFR2 serves as the most important target of anti-angiogenic therapy for cancers. Single-chain trimer (SCT) comprising antigen peptide, β2-microglobulin (β2m), and major histocompatibility complex (MHC) class I heavy chain was a… (More)
A new ecdysteroside was isolated from the roots of Lygodium japonicum (Thunb.) Sw. The structure was identified as 2beta,3beta,14alpha,20R,22R-pentahydroxy-24R-methyl-5beta-cholest-7-en-6-one-3-O-beta-D-glucopyranoside by spectral and chemical methods.
A new arylbenzofuran, 4-hydroxy-2-(4′-hydroxy-2′-methoxyphenyl)-6-methoxybenzofu-ran-3-carbaldehyde (1), was isolated from the aerial parts of alfalfa (Medicago sativa L.), together with three known compounds. The structure of the new compound (1) was determined by spectroscopic methods.
