生物活性
Kuraridine 是一种从苦参根中得到的酮醇提取物。Kuraridine 对 cGMP 特异性磷酸二酯酶 5 型 (PDE5) 有抑制作用，IC50 值为 0.64 μM。靶点
|
PDE5 0.64 μM (IC 50 ) |
体外研究
Kuraridine shows potent inhibitory activity (IC 50 =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 I GABA induced by a saturating GABA concentration (1 mM).Kuraridine induces a concentration–response curves for I GABA enhancement (EC 50 =4.0±2.4 μM) in Xenopus oocytes expressing GABA A receptors composed of α1, β2, and γ2S subunits.
