متن کاملImmunoinhibitory Effect of Teuclatriol a Guaiane Sesquiterpene from Salvia mirzayanii
Background: Salvia mirzayanii, a native plant to Iran, is shown to have immunomodulatory effects on lymphocyte proliferation. Objective: To identify the bioactive immunomodulatory compound(s) present in S. mirzayanii. Methods: The crude extract was fractionated to five fractions in two steps using different solvents. The fractions were subjected to bioassay-guided fractionation. All the fractio...
متن کاملA dimeric state for PRC2
Polycomb repressive complex-2 (PRC2) is a histone methyltransferase required for epigenetic silencing during development and cancer. Long non-coding RNAs (lncRNAs) can recruit PRC2 to chromatin. Previous studies identified PRC2 subunits in a complex with the apparent molecular weight of a dimer, which might be accounted for by the incorporation of additional protein subunits or RNA rather than ...
متن کاملCynaratriol, a sesquiterpene lactone from Centaurea musimomum
THE TITLE COMPOUND [SYSTEMATIC NAME: 3,8-dihydr-oxy-3-(hydroxy-meth-yl)-9-methyl-6-methyl-enedeca-hydro-azuleno[4,5-b]furan-2(3H)-one], C(15)H(22)O(5), is a sesquiterpene lactone showing the typical tricyclic guaianolide skeleton which has been isolated, together with other related metabolites, from the plant Centaurea musimomum. The present study confirms the mol-ecular structure, assigned by ...
متن کاملA sesquiterpene distress signal transmitted by maize.
Plants release a blend of volatile defense compounds in response to herbivore feeding. Whereas some of these volatiles act as direct deterrents, others serve as indirect defense signals that attract natural enemies of the foraging herbivores (reviewed in Dicke et al., 2003). For instance, the signal emitted from maize leaves damaged by lepidopteran larvae attracts parasitic wasps that deposit t...
