Hispidulin is a natural flavone with a broad spectrum of biological activities. Hispidulin is a Pim-1 inhibitor with an IC₅₀ of 2.71 μM.

IC50: 2.71 μM (Pim-1)^[1]

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^[2].

Hispidulin shows significant inhibitory effect on mice tumor size^[2]. Hispidulin treatment effectively prevents ovariectomy-induced body weight loss and attenuates ovariectomy-induced bone loss. Hispidulin treatment also decreases trabecular spacing in ovariectomy mice^[3]. 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^[4].

HepG2 cells are treated with different concentrations of hispidulin (50, 100, 200 μM) for 24, 48 and 72 h. Following treatment, cells are further incubated with MTT reagents at 37°C for 4 h before DMSO is added, to dissolve farmazan crystals, and absorbance is measured at 570 nm in a microplate reader^[2].

Mice: Tumor are established in mice. Mice are treated with DMSO or Hispidulin at a dosage of 10, 20 or 40 mg/kg/day for 35 days. The body weight of tumour-bearing mice is recorded every week and tumour volume is calculated ^[2].
