Hispidulin (Dinatin), an active natrual ingredient in a number of traditional Chinese medicinal herbs, exhibits inhibitory activity against the oncogenic protein kinase Pim-1 with IC50 of 2.71 μM. Hispidulin induces apoptosis through mitochondrial dysfunction and inhibition of P13k/Akt signalling pathway in HepG2 cancer cells. Hispidulin exerts anti-osteoporotic and bone resorption attenuating effects via activating the AMPK signaling pathway.

How to use

In Vitro:

Hispidulin induces cell death in a dose- and time-dependent manner in HepG2 cells. Hispidulin induces apoptosis through mitochondrial dysfunction, which is characterized by decreased Bcl-2/Bax ratio, disrupted mitochondrial membrane potential and increased release of cytochrome C and activated capase-3.

In Vivo:

Hispidulin shows significant inhibitory effect on mice tumor size. Hispidulin treatment effectively prevents ovariectomy-induced body weight loss and attenuates ovariectomy-induced bone loss. Hispidulin treatment also decreases trabecular spacing in ovariectomy mice. Intraperitoneally administering hispidulin(10 or 50mg/ kg) to rats 30 min before intraperitoneally injecting kainic acid (15mg/kg) increases seizure latency and decreases seizure score. In addition, hispidulin substantially attenuates kainic acid-induced hippocampal neuronal cell death, and this protective effect is accompanied by the suppression of microglial activation and the production of proinflammatory cytokines such as interleukin-1β, interleukin-6, and tumor necrosis factor-α in the hippocampus.
