生物活性:
Kuraridine is a prenylated flavonol extract from the roots of?Sophora flavescens. Kuraridine has an inhibitory effect on cGMP specific phosphodiesterase type 5?(PDE5) (IC50=0.64 μM).

体外研究:
Kuraridine shows potent inhibitory activity (IC50=0.64 μM) against cGMP PDE5 with 2.0- and 12.9-fold selectivity over PDE3 and PDE4, respectively.Kuraridine induces pronounced chloride inward currents in the absence of GABA. Thecurrents does not exceed 10% of the maximal?IGABA?induced by a saturating GABA concentration (1 mM).Kuraridine induces a concentration–response curves for?IGABA?enhancement (EC50=4.0±2.4 μM) in Xenopus?oocytes expressing GABAA?receptors composed of?α1, β2, and?γ2S?subunits.
