Description
Betulinic acid is a natural pentacyclic triterpenoid, acts as a eukaryotic topoisomerase I inhibitor, with an IC50 of 5 μM, and possesses anti-HIV, anti-malarial, anti-inflammatory and anti-tumor properties[1][2][3][4].

In Vitro
Betulinic acid is a eukaryotic topoisomerase I inhibitor, with an IC50 of 5 μM, and prevents topoisomerase I-DNA interaction[1]. Betulinic acid (10, 20, 40, 80, and 160 μM) significantly suppresses MDA-MB-231 cell viability in a time- and dose-dependent manner after treatment for 24 or 48 h.? Betulinic acid (20, 40 μM) causes decrease in Bcl-2 expression of MDA-MB-231 cells. Betulinic acid also induces morphological changes of MDA-MB-231 cells at 20 μM, and leads to ultrastructure changes of MDA-MB-231 cells at 40 μM[2]. Betulinic acid shows anti-HIV activities, with an EC50 of 1.4 μM in acutely infected H9 lymphocytes[4].

In Vivo
Betulinic acid (10 and 30 mg/kg, p.o.) significantly abrogates colon shortening, and reduces malondialdehyde (MDA) and lipid hydroperoxide levels in dextran sulfate sodium (DSS)-induced colitis in mice. Betulinic acid (30 mg/kg, p.o.) restores superoxide dismutase (SOD), catalase activity and glutathione (GSH) content to control levels in DSS-induced colitis in mice. Betulinic acid (30 mg/kg, p.o.) also inhibits the DSS-induced increase in inflammatory markers. Betulinic acid (3, 10, 30 mg/kg, p.o.) suppresses acetic acid-induced writhing responses and mustard oil (MO)-induced visceral nociception in mice[3].

*Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles. Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day. The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Protocol 1
Add each solvent one by one: 10% DMSO 90% Corn Oil
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μLDMSO stock solution (20.8 mg/mL) to 900 μLCorn oil, and mix evenly.
For the following dissolution methods, please prepare the working solution directly.
It is recommended to prepare fresh solutions and use them promptly within a short period of time. The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution.
If precipitation or phase separation occurs during preparation,
heat and/or sonication can be used to aid dissolution.
Protocol 1
Add each solvent one by one: 50% PEG300 50% Saline
Solubility: 4 mg/mL (8.76 mM); Suspended solution; Need ultrasonic
Protocol 2
Add each solvent one by one: 0.5% CMC-Na/saline water
Solubility: 2 mg/mL (4.38 mM); Suspended solution; Need ultrasonic

Cell Assay
[2]
CCK-8 is used in the assay. MDA-MB-231 cells are cultured in 96-well plates at a density of 2 × 103 cells/well and then treated with DMSO vehicle or various concentrations of Betulinic acid ranging from 5 µM to 160 µM in 100 µL of medium for the indicated times. After the treatment period, the medium in each well is replaced with 110 µL of medium containing 10 µL of the CCK-8 mixture, and the plates are incubated for 1 h and 30 min at 37°C. The absorbance at a wavelength of 450 nm is measured with a microplate reader[2].

Animal Administration
[3]
Female Swiss albino mice are administered vehicle (5% v/v DMSO in peanut oil) or Betulinic acid (3, 10 or 30 mg/kg) in vehicle, orally. After 1 h, acetic acid (300 mg/kg) is administered by intraperitoneal route and number of writhing response of each animal is counted for 20 min by an observer who is blind to the treatments. Writhing response is when animal rubs its abdomen on surface of table/floor with elongation of the body and extension of the hind limbs[3].

Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
