Chemical Constituents of the Roots of Euphorbia micractina.

30 Aug 2009 Nine minor new tirucallane (1-7) and euphane (8 and 9) triterpenoids including five hydroperoxides, together with 18 known compounds, have been isolated from an ethanolic extract of the roots of Euphorbia micractina. Their structures including ... Read more...

17-hydroxy-jolkinolide B inhibits signal transducers and activators of transcription 3 signaling by covalently cross-linking Janus kinases and induces apoptosis of human cancer cells.

23 Aug 2009 Constitutive activation of the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway occurs frequently in cancer cells and contributes to oncogenesis. Among the members of STAT family, STAT3 plays a pivotal role in the ... Read more...

Diterpenoids and triterpenoids from Euphorbia retusa.

29 Jun 2009 Six new ent-abietane lactones (1-6), three new esterified tetracyclic triterpenes (7-9), and seven known diterpenoids and triterpenoids were isolated from the roots of Euphorbia retusa. Their structures were elucidated by means of spectroscopic ... Read more...

Technical information about 'Euphorbia'

Definition: A large plant genus of the family EUPHORBIACEAE, order Euphorbiales, subclass Rosidae. They have a milky sap and a female flower consisting of a single pistil, surrounded by numerous male flowers of one stamen each. Euphorbia hirta is rarely called milkweed but that name is normally used for ASCLEPIAS.
