The CHCl3 extract of the root of Angelica japonica showed high inhibitory activity against human gastric adenocarcinoma (MK-1) cell growth. From this extract, a new furanocoumarin named japoangelone and four furanocoumarin ethers of falcarindiol, named japoangelols A-D, were isolated together with caffeic acid methyl ester, four polyacetylenic compounds (panaxynol, falcarindiol, 8-O-acetylfalca...
Osthole-mediated cell differentiation through BMP-2/p38 and ERK1/2 pathway in human osteoblast cells
The interaction of human serum albumin (HSA) with osthole was investigated by fluorescence spectroscopy. Osthole can quench the fluorescence of HSA and the quenching mechanism is a static process. The binding site number n and apparent binding constant K were measured at different temperatures. The thermodynamic parameters ΔH0, ΔG0 and ΔS0 were calculated at different temperatures. The results ...
Synthesis, characterization, and antimicrobial evaluation of polyvinylalcohol-osthol composite films
Although poly-vinyl alcohol (PVA) has certain mechanical drawbacks such as a weak barrier, it widely been used in food packaging over the last many years. To increase suitability of PVA (C2H4O)n and render ideal for packaging, diversity studies have already carried out. In below-mentioned script, we, first time, report use natural product osthol making new composite with enhancing thermal, phys...
coumarins are bioactive secondary metabolites and could be found in the fruits of umbelliferae. prangos asperula boiss. is an iranian native plant which is found wild in many regions of iran. osthol, a prenylated coumarin, was isolated from the hexane extract of the fruits of p. asperula and its structure was elucidated using 1 hnmr, 13 cnmr, ir and ms spectra. the essential oil of the aerial p...
Phytochemical analysis of the dichloromethane:methanol (1:1) extract of root parts of Prangos pabularia led to the isolation of twelve cytotoxic constituents, viz., 6-hydroxycoumarin (1), 7-hydroxycoumarin (2), heraclenol-glycoside (3), xanthotoxol (4), heraclenol (5), oxypeucedanin hydrate (6), 8-((3,3-dimethyloxiran-2-yl)methyl)-7-methoxy-2H-chromen-2-one (7), oxypeucedanin hydrate monoacetat...
