| 动物实验 |
1. Prediabetic mouse model and drug administration (Reference [1]): 6-week-old male C57BL/6 mice were fed HFD for 1 week, then injected with STZ (40 mg/kg, intraperitoneal) once daily for 5 days. After 4 weeks, mice with fasting blood glucose 6.1-7.0 mmol/L were defined as prediabetic. Oroxin A was dissolved in 0.5% carboxymethyl cellulose (CMC) to concentrations of 1 mg/mL and 2 mg/mL. Mice were given oral gavage of 10 mg/kg or 20 mg/kg Oroxin A once daily for 8 weeks; the model group received 0.5% CMC [1]
2. Sample collection and detection (Reference [1]): After 8 weeks of administration, mice were fasted for 12 hours, blood was collected via orbital venous plexus to detect fasting blood glucose and insulin. Livers were excised, part was fixed in 4% paraformaldehyde for histological analysis, and part was homogenized for Western blot/qPCR to detect insulin signaling proteins and inflammatory factors [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
1. In vivo safety (Reference [1]): During 8-week treatment with Oroxin A (10, 20 mg/kg, oral), no mouse mortality was observed. Body weight of the 20 mg/kg group (28.5 ± 1.2 g) was not significantly different from the model group (27.8 ± 1.0 g). Serum ALT (26 ± 4 U/L), AST (70 ± 6 U/L), and creatinine (42 ± 5 μmol/L) in the 20 mg/kg group were within normal ranges [1]
2. In vitro safety (Reference [2]): Oroxin A (up to 40 μM) had no significant cytotoxicity on normal human breast epithelial cells (MCF-10A), with cell viability >85% (MTT assay) [2] |

Oroxin A has been reported in Scutellaria comosa, Scutellaria immaculata, and other organisms with data available.
1. Source and structure (Reference [1][2]): Oroxin A is a flavone compound isolated from the seeds of Oroxylum indicum (a traditional Chinese medicinal plant commonly known as "Muhudie") [1][2] 2. Mechanism of action: (1) In prediabetes: Oroxin A improves insulin sensitivity by activating the AKT-GLUT4 signaling pathway and inhibiting systemic inflammation [1]; (2) In breast cancer: It inhibits cell proliferation by inducing robust ER stress (upregulating GRP78/CHOP) and cellular senescence (upregulating p16/p21) [2] 3. Therapeutic potential: Oroxin A shows potential in preventing prediabetes progression to type 2 diabetes and treating ER-positive/triple-negative breast cancer [1][2] |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
