In order to identify active constituents and to gain some information regarding their mode of action, extracts from leaves of Epipremnum pinnatum were tested for their ability to inhibit inflammatory gene expression in endothelial- and monocyte-like cells (HUVECtert and THP-1, respectively).
The crude extract (IPA) of the plant Ipomoea pes-caprae (L.) R. Br. has previously been shown to antagonize smooth muscle contractions induced by several agonists via a non-specific mechanism. Bioassay-guided fractionation of IPA resulted in isolation of the antispasmodically acting isoprenoids
Structural comparison of apple constituents with known inducers of phase two cytoprotective enzymes led to the identification of 3-hydroxy-beta-damascone and related carotenoid derived aroma compounds as potent inducers of NAD(P)H:quinone reductase (QR) activity. Damascone-related compounds were
