Daphne-type diterpenes from genus Daphne and their anti-tumor activity

Daphne-type diterpenenoids is the major biologically active constituents in the genus Daphne. We find that there are about 101 Daphne-type diterpenes in this genus, most of these compounds show different degrees of inhibitory effect on various cancer cell. Some of them have been studied in depth and the potent molecular mechanisms might be associated with modulation of different cell-signaling pathways. In addition, some compounds of this type also can inhibit the synthesis of protein and DNA. Absolutely, the anti-tumor activity of Daphne-type diterpenes is worthy of attention. Unfortunately, most of the current research on the activity of these compounds is focused on simple drug efficacy, and its in-depth mechanism research is far from enough. On the other point of view, there still exists wide growing space on the depth of these compounds.     

Assessment of anti-inflammatory and antinociceptive activities of Daphne pontica L. (Thymelaeaceae)

The n-hexane, diethylether, ethyl acetate and methanol extracts from roots, leaves, stems and flowers with young leaves of Daphne pontica L. (Thymelaeaceae) were investigated for their in vivo anti-inflammatory and antinociceptive activities. For the anti-inflammatory activity assessment, carrageenan-induced hind paw edema, PGE(2)-induced hind paw edema and 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema models and for the antinociceptive activity, p-benzoquinone-induced abdominal constriction test were used. Only ethyl acetate extracts of the roots showed significant anti-inflammatory activity on carrageenan-induced (22.7-32.0% inhibition) and PGE(2)-induced hind paw edema (3.2-27.3% inhibition) as well as 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema (47.8-43.3% inhibition) models at 50 mg/kg dose without inducing any apparent gastric lesion or acute toxicity, whereas the other extracts were shown to be ineffective. In addition to roots, ethyl acetate extracts of the stems exhibited 19.5-29.9%; 5.3-23.9%; 36.6-28.1% inhibition on carrageenan-induced and PGE(2)-induced hind paw edema as well as 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema models, respectively. On the other hand, none of the extracts showed any significant antinociceptive activity.
