Betulinic acid is a natural pentacyclic triterpenoid compound and an inhibitor of eukaryotic topoisomerase I with an IC50 value of 5 μM[1]. Betulinic acid has anti-inflammatory, anti-malarial, anti-AIDS and anti-tumor activities[2]. Betulinic acid can inhibit α-glucosidase with an IC50 value of 10.6 μM[3].
In vitro, betulinic acid (7.5 μM) treatment of mouse hypothalamic cell line (mHypoE-46) neurons for 10 h significantly inhibited the enzymatic activity of protein tyrosine phosphatase 1B (PTP1B) by 35%[4]. Betulinic acid (10-160 μM) treatment of MDA-MB-231 cells for 24 or 48 h inhibited cell viability in a time- and dose-dependent manner, reduced Bcl-2 expression in cells, and induced ultrastructural changes in cells[5].
In vivo, oral administration of betulinic acid (50 mg/kg) to treat retinal ischemia model mice prevented retinal GCL cell loss and optic nerve axon loss, partially blocked retinal arteriolar endothelial dysfunction, inhibited ROS production in retinal blood vessels, and enhanced the mRNA expression of antioxidant enzymes SOD3 and HO-1[6]. Oral administration of betulinic acid (30 mg/kg) to treat colitis mice significantly prevented colon pathological changes such as diarrhea and bleeding, reduced nitrite, malondialdehyde, peroxidase and lipid peroxide levels, and increased superoxide dismutase, catalase and glutathione levels[7].

Cell experiment [1]: | |
Cell lines | Mouse hypothalamic cell line (mHypoE-46) neurons |
Preparation Method | Lupeol (28 μM) and betulinic acid (7.5 μM) were applied to the mHypoE-46 cell line for 10 h. The cells were collected for western blot and immunoprecipitation analysis. |
Reaction Conditions | 7.5μM; 10h |
Applications | Lupeol and betulinic acid significantly inhibited the enzymatic activity of protein tyrosine phosphatase 1B (PTP1B) by 35%. |
Animal experiment [2]: | |
Animal models | Male C57Bl/6J mice |
Preparation Method | One day before induction of retinal ischemia (I/R), mice received 50 mg/kg body weight of betulinic acid or DMSO by gavage. 24 hours later, mice received a second dose of betulinic acid or vehicle solution, followed by anesthesia with xylocaine and ketamine to induce retinal ischemia. For the next seven days, mice received betulinic acid or vehicle solution once a day. Mice were sacrificed on day 8 for further studies. |
Dosage form | 50mg/kg; p.o. |
Applications | Following I/R, betulinic acid prevented retinal GCL cell loss and optic nerve axon loss, partially blocked retinal arteriolar endothelial dysfunction, inhibited ROS production in retinal vessels, and enhanced the mRNA expression of antioxidant enzymes SOD3 and HO-1. |
