Biological Activity

Betulinic acid is a pentacyclic triterpene which induces apoptosis and antiangiogenic responses in tumors derived from multiple tissues. Betulinic acid shows anti-HIV activity by blocking HIV replication in H9 lymphocytes with an EC50 value of 1.4 μM and inhibiting uninfected H9 cell growth with an IC50 value of 13 μM. In vivo, Betulinic acid inhibits prostate cancer cell and tumor (xenograft) growth in athymic nude mice bearing LNCaP cells and this is due, in part, to proteasome-dependent downregulation of Sp1, Sp3, Sp4 and several Sp-regulated genes.

Cell Experiment
Cell lines H9 lymphocytes
Preparation method Incubating H9 lymphocytes ( 1 ×107 cells/ml) in the presence or absence of HIV-1 (IIIB isolate) for 1 h at 37 °C. Washing cells thoroughly to remove unadsorbed virions and resuspending in culture medium. Adding betulinic acid (diluted in test medium) to the culture medium. After incubation for 3 days at 37 °C, the cell densities of uninfected cultures are determined to assess toxicity of betulinic acid. Using a p24 antigen capture assay to determine the level of HIV infection in HIV-treated culture
Incubation time 3 days
Animal Experiment
Animal models LNCaP tumor xenograft model
Formulation Diluted in corn oil containing 1% DMSO
Dosages 10 and 20 mg/kg/d
Administration Orally
Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
