3,8’-Biapigenin is a polyketide synthase-derived biflavonoid that has been found in Hypericum and has diverse biological activities.1,2,3,4,5 It inhibits protein tyrosine phosphatase 1B (PTP1B; IC50 = 4.5 µM) and stimulates glucose uptake in 3T3-L1 adipocyte cells when used at concentrations of 5 and 10 µM.2 3,8’-Biapigenin inhibits the cytochrome P450 (CYP) isoforms CYP3A4, CYP2C9, and CYP1A2 (Kis = 0.038, 0.32, and 0.95 µM, respectively).3 It reverses cell death induced by kainate and NMDA in isolated rat embryonic hippocampal neurons when used at a concentration of 10 µM.4 3,8’-Biapigenin (8 mg/kg) decreases carrageenan-induced paw edema and protects against gastric lesions induced by indomethacin in rats.5

计算结果:
工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
