In-Depth Information
leaf are covered with sharp, pointed straight and stiff hairs. Heads (1 cm
diameter) are yellow and stalked. Involucral bracts are oblong-ovate. Ray
lowers, numbering about 10, are broad and spreading. Disk lowers, num-
bering about 20, are short, narrow, and pointed.
Compounds and activities: The antiproliferative compounds isolated from this
species include indole-3-carboxyaldehyde, wedelolactone, luteolin, and
apigenin possessing an androgen receptor (AR) suppression (inhibition)
property. The 50% inhibition concentration values of these compounds
(with respect to their ability to modulate the AR activation of transcription
from prostate-speciic antigen promoter in prostate cancer [PCa] cells) were
found to be 34.9, 0.2, 2.4, and 9.8 µm, respectively (Lin et al., 2007).
