Description

Daphnetin (DAP), a natural coumarin derivative isolated from Chinese medicinal herbs, possesses abundant biological activities, such as anti-inflammatory, antioxidant, antimalarial and anti-arthritic. Experiments on mice have shown, that DAP exerts neuroprotective and anti-inflammatory effects, and the potential mechanism is involved the inhibition of TLR4/NF-κB mediated inflammatory signaling pathway. Besides, DAP, a multi-targeted medication, can have the application for the anti-angiogenesis and cancer therapy, through the inhibition of the IKKs/IκBα/NF-κB, Src/FAK/ERK1/2 and Akt signaling pathways. It is known, that protein kinases play key roles in the control of cell proliferation, differentiation, and metabolism. Daphnetin inhibits tyrosine-specific protein kinase, EGF receptor, serine/threonine-specific protein kinases, including cAMP-dependent protein kinase (PKA) and protein kinase C (PKC).

Sample Use Guides

In Vivo Use Guide
in rats: six sprague-dawley rats received intragastric administration of D. giraldii extract (daphnetin, daphnoretin and daphneticin were 88.40, 3.24 and 4.28 mg•kg⁻¹, respectively).
Route of Administration: Intragastric
In Vitro Use Guide
To test the in vitro effect of daphnetin on cytochrome C oxidase (COX) and ribonucleotide reductase (RNR) activity of Plasmodium falciparum. The parasites synchronized with sorbitol in vitro was treated by daphnetin and daphnetin-Fe complex. The inhibition level of the COX activity by daphnetin after being treated for 2, 4, 8 and 12 h were 0.6%, 73% and 80% respectively and the inhibition level by daphnetin at different concentrations (0.1, 1, 100 and 1 mmol/L) for 6h was 3%, 31%, 53% and 84%, respectively.
