Biological Activity

Description Betulinic acid (ALS-357, Lupatic acid, Betulic acid), a pentacyclic triterpenoid from Syzigium claviflorum, is a inhibitor of HIV-1 with EC50 of 1.4 μ M. It's reported that Betulinic acid acts as a new activator of NF-κB.Phase 1/2.
Targets
HIV-1 [1] Eukaryotic topoisomerase I [3] Aminopeptidase N [2]
1.4 μM(EC50) 5 μM 7.3 μM
In vitro
In vitro 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. [1] Betulinic acid also acts as anti-melanoma agent through inhibiting aminopeptidase N activity with IC50 of 7.3 μM. [2] In addition, Betulinic acid inhibits eukaryotic topoisomerase I activity with IC50 of 5 μM and can be exploited as a strong candidate for anti-tumor drug. [3]
Kinase Assay Topoisomerase I-DNA interaction
Annealed 25-mer duplex of oligonucleotide-1 and oligonicleotide-2 is incubated with 25 or 50 units of rat liver topoisomerase I at 8 °C for 15 min in the presence or absence of betulinic acid in binding buffer. After incubation the reaction mixtures are electrophoresed in 7% non-denaturing polyacrylamide gel at 4 °C in 0.167 × TBE buffer and DNA bands are stained with ethidium bromid
In Vivo
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. [4]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
