Phanginin A 是一种有效的具有口服活性的SIK1激活剂。Phanginin A 抑制糖异生。Phanginin A 增加 p-SIK1 的表达并降低 p-CREB 的表达。Phanginin A 可降低血糖水平并改善葡萄糖耐量和血脂异常。Phanginin A 具有用于 2 型糖尿病研究的潜力。
| 生物活性 | Phanginin A is a potent and orally activeSIK1(salt-induced kinase 1)activator. Phanginin A inhibited gluconeogenesis. Phanginin A increases the expression of p-SIK1 and decreases the expression of p-CREB. Phanginin A reduces blood glucose levels and improves glucose tolerance and dyslipidemia. Phanginin A has the potential for the research of type 2 diabetes[1]. |
