生物活性
Biochanin A is a naturally occurring fatty acid amide hydrolase (FAAH) inhibitor, which inhibits FAAH with IC50s of 1.8, 1.4 and 2.4 μM for mouse, rat, and human FAAH, respectively.
体外研究
(In Vitro)
Biochanin A inhibits the hydrolysis of 0.5 µM AEA by mouse, rat and human FAAH with IC50 s of 1.8, 1.4 and 2.4 µM respectively. FAAH is inhibited by Biochanin A with a pIC50 value of 6.21±0.02, corresponding to an IC50 value of 0.62 µM. Biochanin A produces significant inhibition of the URB597-sensitive tritium retention at high nanomolar-low micromolar concentrations. Experiments are run with human FAAH and 0.5 µM [3H]AEA with assay conditions giving these higher utilization rates, the activity is still inhibited by Biochanin A, Genistein, Formononetin and Daidzein in the low micromolar range (IC50s of 6.0, 8.4, 12 and 30 µM, respectively)[1].
体内研究
(In Vivo)
Biochanin A is tested at doses of 30, 100 and 300 µg. The highest dose also reduced formalin-induced ERK phosphorylation in a manner antagonized by AM251. Thus, Biochanin A behaved like URB597 after local administration to the paw. In anaesthetized mice, URB597 (30 µg i.pl.) and Biochanin A (100 µg i.pl.) both inhibit the spinal phosphorylation of extracellular signal-regulated kinase produced by the intraplantar injection of formalin. The effects of both compounds are significantly reduced by the CB1 receptor antagonist/inverse agonist AM251 (30 µg i.pl.). Biochanin A (15 mg/k i.v.) does not increase brain AEA concentrations, but produces a modest potentiation of the effects of 10 mg/kg i.v. AEA in the tetrad test. Biochanin A (15 mg/kg i.v.) is without effects on its own, but significantly potentiates the effects of AEA (10 mg/kg i.v.)[1].
