藥理活性: Antiarrhythmic (rat arrhythmia caused by BaCl2);inhibits fatigue; antiviral; inhibits replication of HSV-1; bidirectional action to blood pressure (mus, first increases and then lowers blood pressure, whileheart rate slows); calcium antagonist; increases blood pressure (injecting0.3μL into lateral area of rat hypothalamus, average arteriotony noticeablyrising); antioxidant (rat hepatic homogenate, caused by H2O2, IC50 =644.8μg/mL); cAMP phosphodiesterase inhibitor (in vitro, IC50 = 137μmol/L);antihypercholesterolemic (reduces the level of cholesterol in serum); promotesbiosynthesis of DNA, protein and lipid (murine marrow cells); enhancescytotoxic effects of daunomycin and vincaleucoblastine; promotes plasma
secretion of corticosterone (ED50 = 112μmol/kg); liver and nerve protectant;reduces uterine contraction (gpg, in vitro, caused by acetylcholine);vasodilator (dog); anti-inflammatory (modulator of cytokine network: inhibits IC50 = 56.5μmol/Land 51.3μmol/L, respectively); antinociception (i.t.injected 0.7μg substance P-induced pain model, EC = 50μg i.t.); neurite
outgrowth enhancer (hmn neuroblastoma SK-N-SH cells, 100μmol/L, total length of neurites = 149.3μm, number of varicosity per cell = 0.93, p<0.05;control, total length of neurites = 45.3μm, number of varicosity per cell =0.10); hepatoprotective (inhibits activation of macrophages, inhibitsincrease in sALT and sAST levels, in vivo, D-GalN/LPS-induced liver injury in mouse, 100mg/kg ip for sALT, InRt = 33%; 100mg/kg ip for sAST, InRt =40%; control Hydrocortisone, 20mg/kg ip for sALT, InRt = 99%; 20mg/kg ipfor sAST, InRt = 97%).
