Chemical Constituents from Euphorbia kansui.
In this research, a new triterpenoid, tirucalla-8,24-diene-3β,11β-diol-7-one (1), and eupha-8,24-diene-3β,11β-diol-7-one (2), which was isolated from Euphorbia kansui for the first time, together with twelve other known compounds (3-14), were isolated from the ethyl acetate extract of Euphorbia kansui. Their structures were elucidated based on High resolution electrospray ionization mass spectr...
متن کاملThree antinematodal diterpenes from Euphorbia kansui.
Three compounds, 20-O-acetyl-[3-O-(2'E,4'Z)-decadienoyl]-ingenol (1), 20-O-acetyl-[5-O-(2'E,4'Z)-decadienoyl]-ingenol (2) and 3-O-(2'E,4'Z)-decadienoylingenol (3), were isolated from Euphorbia kansui under the bioassay-guided method. Each compound showed the same antinematodal activity against the nematode, Bursaphelenchus xylophilus, at a minimum effective dose (MED) of 5 microg/cotton ball.
متن کاملEuphorbia Kansui Reactivates Latent HIV
While highly active anti-retroviral therapy has greatly improved the lives of HIV infected individuals, these treatments are unable to eradicate the virus. Current approaches to reactivate the virus have been limited by toxicity, lack of an orally available therapy, and limited responses in primary CD4+ T cells and in clinical trials. The PKC agonist ingenol, purified from Euphorbia plants, is ...
متن کاملChemical constituents of Euphorbia marschalliana Boiss.
Acetone extract of aerial parts of Euphorbia marschalliana collected from Iran has been subjected to different chromatography techniques for fractionation and purification. The stereo-structures of the myrsinol esters 15-O-acetyl-3-O-propionyl-5-O-butanoyl-7-O-nicotinoylmyrsinol (1) and 15-O-acetyl-3,5-O-dibutanoyl-7-O-nicotinoylmyrsinol (2) have been probed using ROESY spectroscopy and modifie...
متن کاملTermiticidal activity of diterpenes from the roots of Euphorbia kansui.
Five ingenane compounds, 1-5, kansuinins A and B, isolated from Euphorbia kansui, and their derivatives 7 and 9 were tested for termiticidal activity against the Japanese termite, Reticulitermes speratus. At 72 hours after treatment, the ingenane compounds 1 to 5 caused 100% mortality in R. speratus at 50, 25 and 12.5 microg/disk, respectively, except for compound 1, which gave a mortality rate...
