A range of 18 derivatives of flavone‐8‐acetic acid (FAA) with substituents on the 2‐phenyl group have been prepared and their anti‐tumour activity evaluated in vitro against a panel of human and murine tumour cell lines and in vivo against MAC 15A. There was no clear‐cut relationship between in vitro and in vivo activity but the activity in each situation was found to be very sensitive to the precise

The title compound, which was reported to be a constituent of the fruiting body of the fungus Antrodia camphorata, has been synthesized. The reactivity and spectroscopic properties of the synthetic material do not match those of the natural product. There is currently insufficient information for a definitive structural reassignment.
Anti-inflammatory Benzenoids from <i>Antrodia </i><i>camphorata</i>
Four new compounds, including three new benzenoids, antrocamphin A (1), antrocamphin B (2), and 2,3,4,5-tetramethoxybenzoyl chloride (3), and a new 1,3-dioxolan-2-one derivative, antrodioxolanone (4), together with 13 known compounds have been isolated from the fruiting body of Antrodia camphorata. The structures of these new compounds were determined through spectral analyses including extensive 2D-NMR data. Among the isolates, antrocamphin A (1), antcin A (10), and antcin B (11) exhibited potent inhibition against fMLP-induced superoxide production with IC50 values less than 10 mu M.
