چکیده

Three new macrocyclic diterpenes, kansuinins F (1), G (2), and H (3), together with four known jatrophane diterpenes, kansuinins D (4), E (5), and A (6) and 3beta,5alpha,7beta,15beta-tetraacetoxy-9alpha-nicotinoyloxyjatropha-6(17)-11E-dien-14-one, were isolated from the roots of Euphorbia kansui. Compounds 1 and 2 were assigned as 6(17)-en-11,12-epoxy-14-one-type jatrophane diterpenes, and compound 3 as a 6(17)-en-11,14-epoxy-12-one jatrophane diterpene. The structures of compounds 1-3 and the relative configurations of compounds 4 and 5 were determined by spectral data analysis. Kansuinin E (5) exhibited a specific survival effect on fibroblasts that expressed TrkA, a high-affinity receptor for nerve growth factor.

Termiticidal 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...

Three 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.
